Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    The present application claims priority under 35 U.S.C. §365 to International Patent Application No. PCT/CN2014/075426 filed Apr. 15, 2014 which is incorporated herein by reference in its entirety. 
     
    
     TECHNICAL FIELD 
       [0002]    The present invention relates to the field of mobile communications technologies, and in particular, to a right control method, a client, and a server. 
       BACKGROUND 
       [0003]    The Web (web) has been widely applied in application systems of various organizations, such as a government and an enterprise. In these web application systems, it is a very important function that different users are controlled to have different access rights for different resources. 
         [0004]    In the prior art, generally there are the following several methods for controlling access right of a user: 
         [0005]    1. On a web page, a right element such as a button or a hyperlink can be displayed, and all users can see the right element and initiate an operation. After receiving a request sent by a user, a web server performs right determining according to a URL (uniform resource locator); if the user has no right, the web server intercepts access and returns error information to the user. 
         [0006]    In this solution, only after performing an operation, the user can know whether the user has a right, and in the solution, various operation links of a system are exposed to a user who has no right, which may lead to a potential security risk of the system. 
         [0007]    In addition, all processing in the solution is completed on the server, which increases processing pressure on the server. 
         [0008]    2. An active web technology is used, such as JSP (Java server pages) or ASP (Active Server Page, active server page); on a web page, a segment of code is implanted into each right element, such as a button or a hyperlink; whether these right elements are displayed is controlled by using the implanted code. By implanting the code, a relevant right element is not displayed to a user who has no right. 
         [0009]    This solution is relatively complex during implementation and requires a large amount of code to be implanted, and a server is also under too much processing pressure.

         [0088]    Various aspects are described in this specification with reference to a client and/or a server. 
         [0089]    The client may be a wireless client or a wired client. The wireless client may refer to a device that provides a user with voice and/or data connectivity, a handheld device with a wireless connection function, or another processing device connected to a radio modem. The wireless client may communicate with one or more core networks by using a radio access network (RAN, Radio Access Network). The wireless client may be a mobile terminal, such as a mobile phone (also referred to as a “cellular” phone) and a computer with a mobile terminal, for example, may be a portable, pocket-sized, handheld, computer built-in, or in-vehicle mobile apparatus, which exchanges voice and/or data with the radio access network. For example, it may be a device such as a personal communications service (Personal Communications Service, PCS) phone, a cordless telephone set, a Session Initiation Protocol (SIP) phone, a wireless local loop (WLL, Wireless Local Loop) station, or a personal digital assistant (Personal Digital Assistant, PDA). The wireless client may also be referred to as a system, a subscriber unit (Subscriber Unit), a subscriber station (Subscriber Station), a mobile station (Mobile Station), a mobile device (Mobile Device), a remote station (Remote Station), an access point (Access Point), a remote terminal (Remote Terminal), an access terminal (Access Terminal), a user terminal (User Terminal), a user agent (User Agent), a user device (User Device), or user equipment (User Equipment). 
         [0090]    The server, for example, may be a web server, or may be another server. 
         [0091]    To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. 
         [0092]    In addition, the terms “system” and “network” may be used interchangeably in this specification. The term “and/or” in this specification describes only an association relationship for describing associated objects and represents that three relationships may exist. For example, A and/or B may represent the following three cases: Only A exists, both A and B exists, and only B exists. In addition, the character “/” in this specification generally indicates an “or” relationship between the associated objects. 
         [0093]    The following further describes the embodiments of the present invention in detail with reference to accompanying drawings in this specification. 
         [0094]    Referring to  FIG. 1 , an embodiment of the present invention provides a right control method. A main process of the method is described as follows: 
         [0095]    Step  101 : A client acquires login information input by a user. 
         [0096]    Optionally, in this embodiment of the present invention, that a client acquires login information input by a user may include: the client displays a login interface, where the login interface is a login interface of a website, or the login interface is a login interface of an application; and the client acquires the login information that the user inputs by using the login interface. 
         [0097]    Optionally, in this embodiment of the present invention, the login interface may be a login interface of a website, or the login interface may be a login interface of an application, such as a game application or an office application. 
         [0098]    For example, for some websites, a user needs to perform some background settings. For example, in a campus network, login accounts of an administrator, a teacher, and a student are distinguished from each other and have different rights; or for example, on a company website, an administrator, leaders at all levels, and common staff are distinguished from each other, and different login accounts also have different rights. A user generally needs to provide login information when logging in to this type of website. 
         [0099]    For example, it is also necessary to distinguish rights from each other for some applications. For example, login accounts of players and administrators at different levels are distinguished from each other and have different rights. A user generally needs to provide login information when logging in to this type of application. 
         [0100]    Regardless of whether the user logs in to a website or an application, an interface on which the user inputs the login information may be referred to as the login interface. 
         [0101]    Upon accessing the login interface by using the client, the user needs to input a login account and a password, where the login account and the password of the user are the login information of the user, and the login account may be referred to as a login account of the login information. The present invention sets no limitation to specific forms of the login account and the password. For example, the login information may be voice information, fingerprint information, or text information. 
         [0102]    Step  102 : The client sends the login information to a server, where the login information is used by the server to query right information corresponding to the login information. 
         [0103]    After obtaining the login information, the client may send the login information to the server; and after receiving the login information, the server may query the right information corresponding to the login information. 
         [0104]    Optionally, the server may store a correspondence list, and the correspondence list includes a correspondence between login information and right information that are of each login account, where one piece of login information corresponds to one piece of right information, and one piece of login information corresponds to one login account. 
         [0105]    Optionally, in this embodiment of the present invention, when the login interface is a login interface corresponding to a website, the right information corresponds to the website; when the login interface is a login interface corresponding to an application, the right information corresponds to the application. 
         [0106]    In this embodiment of the present invention, if the login interface is a login interface corresponding to a website, the login information and the website are corresponding to each other, where a meaning of “corresponding” is: The right information refers to right information that is corresponding to the login information and that is for all right elements included in the website, and the website is a website to which a user logs in by using the login information and by using the login interface. For example, the website includes multiple interfaces, where all or some of interfaces include different right elements, that is, the website includes multiple right elements. The right information includes the right information that is corresponding to the login information and that is for all the right elements included by the website. All rights that are corresponding to the login information and for the website can be learned by acquiring the right information. 
         [0107]    Similarly, in this embodiment of the present invention, if the login interface is a login interface corresponding to an application, the login information and the application are corresponding to each other, where a meaning of “corresponding” is: The right information refers to right information that is corresponding to the login information and that is for all right elements included in the application, and the application is an application to which a user logs in by using the login information and by using the login interface. For example, the application includes multiple interfaces, where all or some of interfaces have different right elements, that is, the application includes multiple right elements. The right information includes the right information that is corresponding to the login information and that is for all the right elements included in the application. All rights that are corresponding to the login information and for the application can be learned by acquiring the right information. 
         [0108]    After receiving a piece of login information, the server may query the correspondence list for the login information. If the login information is found, the server may feed back right information corresponding to the login information to the client. If the server does not find the login information, the server may feed back a response message to the client, indicating that the login information is not found, and the client may not control a right of the login account, or the client may directly reject access by the login account. 
         [0109]    A website may include multiple web pages, that is, the website includes multiple interfaces; for a login account, right information corresponding to the login account may cover rights corresponding to the login account on all interfaces included in the website. That is, right information of a login account covers a scope of all rights corresponding to the login account of the website, so that the server needs to send only the right information to the client, and the client can control a right of the login account according to the right information regardless of an interface on which a user performs an operation using the login account. 
         [0110]    Similarly, an application may also include multiple interfaces; for a login account, right information corresponding to the login account may cover rights corresponding to the login account on all interfaces included in the application. That is, right information of a login account covers a scope of all rights corresponding to the login account of the application, so that the server needs to send only the right information to the client, and the client can control a right of the login account according to the right information regardless of an interface on which a user performs an operation using the login account. 
         [0111]    Step  103 : The client receives the right information sent by the server, and controls access right of a login account according to the right information, where the login account is an account corresponding to the login information. 
         [0112]    After receiving the right information, the client can control the access right of the login account according to the right information. 
         [0113]    For example, a website may include multiple right elements, where the right elements can be used to control an access scope; different content can be accessed by performing an operation on different right elements. Therefore, access right of each login account can be controlled by controlling the right elements. A right element may be, for example, a button or a link. 
         [0114]    If a login account has a right for a right element, information about the right element is included in right information corresponding to the login account. If a login account has no right for a right element, information about the right element is not included in right information corresponding to the login account. 
         [0115]    Optionally, in this embodiment of the present invention, that the client controls access right of a login account according to the right information includes: the client determines information about a right element included in each interface of the website; the client determines, according to the right information, whether there is information about a right element, wherein the information is in the determined information about a right element but is not included in the right information; and when there is information about a right element that is not included in the right information, the client forbids displaying of the right element corresponding to the information about the right element that is not included in the right information. 
         [0116]    Then, when receiving the right information, the client can determine information about all right elements included in the website or the application, that is, information about a right element included in each interface belonging to the website or the application. After determining the information about these right elements, the client can determine, according to the right information, whether there is information about a right element, wherein the information is in the determined information about a right element but is not included in the right information. If there is information about a right element that is not included in the right information, it indicates that the login account has no operation right for the right elements. 
         [0117]    If the client determines that there is information about a right element that is in the determined information about the right elements but is not included in the right information, the client can forbid displaying of the right element corresponding to the information about the right elements. That is, if it is determined that the login account has no operation right for a right element, the client can directly forbid displaying of the right element, so that a user using the login account obviously cannot perform an operation on the right element. In addition, the client directly forbids displaying of a right element for which the login account has no right, so that each user can see only a right element for which the user has operation permission, and the user does not perform an operation on a right element for which the user has no right, which reduces operation time of the user and avoids a misoperation of the user. Furthermore, a user having no right cannot see corresponding information, which prevents a user from performing a malicious attack on a system, and ensures security of the system to the greatest extent. 
         [0118]    Optionally, in this embodiment of the present invention, that the client controls access right of a login account according to the right information includes: the client determines information about a right element included in each interface of the website or the application; the client determines, according to the right information, whether there is information about a right element, wherein the information is in the determined information about a right element but is not included in the right information; and when there is information about a right element that is not included in the right information, the client forbids enabling of the right element corresponding to the information about the right element that is not included in the right information. 
         [0119]    When receiving the right information, the client can determine information about all right elements included by the website or the application, that is, information about a right element included in each interface belonging to the website or the application. After determining the information about these right elements, the client can determine, according to the right information, whether there is information about a right element, wherein the information is in the determined information about a right element but is not included in the right information. If there is information about a right element that is not included in the right information, it indicates that the login account has no operation right for the right elements. 
         [0120]    If the client determines that there is information about a right element that is in the determined information about the right elements but is not included in the right information, the client can forbid enabling of the right element corresponding to the information about the right elements. That is, if it is determined that the login account has no operation permission for a right element, the client can forbid enabling of the right element, so that a user using the login account cannot perform an operation on the right element. Forbidding enabling of the right element may mean that the right element is still displayed but may be displayed in an inoperative state, and after seeing this state, a user naturally knows that the right element cannot be operated. In this way, a display effect of an entire page is not damaged; meanwhile, the user is reminded so that the user will not perform a misoperation. 
         [0121]    Optionally, in this embodiment of the present invention, if only enabling the right element is forbidden, and the right element still continues to be displayed, there may be various specific display manners. For example, the right element may be displayed in a highlighted state; the right element may be displayed in a color different from that of another right element, where the another right element may refer to a right element for which the login account has a right; or the right element may be endowed with a display identifier when being displayed. In conclusion, these display manners aim to remind a user that the right element cannot be operated, so as to prevent the user from performing a misoperation. 
         [0122]    Optionally, in this embodiment of the present invention, a website or an application includes multiple right elements; before step  101 , a right customized attribute may be pre-configured for all or a part of the right elements, so that the client can control a right element for which the customized attribute is configured. 
         [0123]    For example, for a right element for which the customized attribute is configured, the client can forbid displaying of the right element or forbid enabling of the right element; however, for a right element for which the right customized attribute is not configured, the client may not be capable of performing similar control over the right element. 
         [0124]    For example, a website includes three right elements in total, which are respectively a right element  1 , a right element  2 , and a right element  3 , where a right customized attribute is pre-configured for the right element  1  and the right element  2 , while the right customized attribute is not configured for the right element  3 . When receiving the right information, the client can determine information about all right elements included by the website, that is, determine information about the right element  1 , information about the right element  2 , and information about the right element  3 . After determining the information about these right elements, the client can determine, according to the right information, whether there is information about a right element, wherein the information is in the determined information about a right element but is not included in the right information; if there is information about a right element that is not included in the right information, it indicates that the login account has no operation permission for the right elements. 
         [0125]    For example, the client determines that the information about the right element  1  and the information about the right element  3  are not included in the right information. Because the right customized attribute is pre-configured for the right element  1 , the client can control the right element  1 , for example, the client can forbid displaying or forbid enabling of the right element  1 , so that a user cannot perform an operation on the right element  1 . However, because the right customized attribute is not pre-configured for the right element  3 , the client cannot control the right element  3 , and the right element  3  may be still normally displayed. 
         [0126]    It can be learned that, the right customized attribute may be configured for a right element that needs to be controlled, where the right element that needs to be controlled may be only a part of all right elements, so as to reduce workload required for configuration. In addition, a right element that can be controlled and a right element that cannot be controlled are distinguished from each other by configuring the right customized attribute, which is more convenient for performing control. 
         [0127]    Referring to  FIG. 2 , based on a same inventive concept, an embodiment of the present invention provides another rights control method, where the method may be applied on a server, and the server may be the server described above. A main procedure of the method is described as follows: 
         [0128]    Step  201 : The server receives login information sent by a client and input by a user. 
         [0129]    Optionally, in this embodiment of the present invention, that the server receives login information sent by a client and input by a user may include: the server receives the login information that is sent by the client and input by the user by using a login interface, where the login interface may be a login interface of a website, or the login interface may be a login interface of an application, such as a game application or an office application. 
         [0130]    Optionally, in this embodiment of the present invention, when the login interface is a login interface corresponding to a website, right information corresponds to the website; or when the login interface is a login interface corresponding to an application, the right information corresponds to the application. 
         [0131]    Regardless of whether the user logs in to a website or an application, an interface in which the user inputs the login information may be referred to as the login interface. 
         [0132]    When entering the login interface by using the client, the user needs to input a login account and a password, where the login account and the password of the user are login information of the user, and the login account is referred to as a login account of the login information. The present invention sets no limitation to specific forms of the login account and the password, for example, the login information may be voice information, fingerprint information, or text information. 
         [0133]    After obtaining the login information, the client may send the login information to the server. 
         [0134]    Step  202 : The server queries, according to the login information, right information corresponding to the login information. 
         [0135]    Optionally, the server may store a correspondence list, where the correspondence list includes a correspondence between login information and right information that are of each login account, and one piece of login information corresponds to one piece of right information. 
         [0136]    Optionally, in this embodiment of the present invention, when the login interface is a login interface corresponding to a website, the right information corresponds to the website; or when the login interface is a login interface corresponding to an application, the right information corresponds to the application. 
         [0137]    In this embodiment of the present invention, login information is in one-to-one correspondence with a website; similarly, login information is also in one-to-one correspondence with an application. That is, the right information mentioned in this embodiment of the present invention refers to right information that is of one login account and for one website, where the website is a website to which a user logs in by using the login account and by using the login information; or the right information mentioned in this embodiment of the present invention refers to right information that is of one login account and for one application, where the application is an application to which a user logs in by using the login account and by using the login information. 
         [0138]    After receiving a piece of login information, the server may query the correspondence list and search for the login information in the correspondence list. If finding the login information, the server may send right information corresponding to the login information to the client; or, if the server does not find the login information, the server may send a response message to the client, indicating that the login information is not found, and the client may not control a right of the login account, or the client may directly reject access of the login account. 
         [0139]    Step  203 : The server sends the right information to the client, where the right information is used by the client to control access right of a login account, and the login account is an account corresponding to the login information. 
         [0140]    After finding the right information corresponding to the login information, the server can feed back the right information to the client. The manner in which the client controls the access right of the login account has been described in detail in the procedure shown in  FIG. 1 , and details are not described herein again. 
         [0141]    Referring to  FIG. 3 ,  FIG. 3  is an interaction flowchart of a user, a client, and a server according to an embodiment of the present invention. An example that a login interface is a login interface corresponding to a website is used in the embodiment of  FIG. 3 , where the user herein may be understood as a login account used by the user. 
         [0142]    First, a website developer can develop a web page, for example, a right control framework may be introduced to add a right customized attribute, so that the client can control a corresponding right element according to whether the login account has a right. In this embodiment of the present invention, a website may include multiple right elements. Optionally, a right customized attribute may be added to each right element, so that each right element can be displayed; or a right customized attribute is added to only some right elements that are relatively important, so that the implementation is simpler. 
         [0143]    A user accesses a web page by using a browser installed on the client; when accessing a website, the user enters a login interface of the website and inputs login information, where the login information corresponds to the login account. The client sends a URL request to the server, where the URL request carries the login information of the user. 
         [0144]    The server may perform a query in a database, where the database may store correspondence list, and the database determines that the login information corresponds to a piece of right information in the correspondence list, that is, determines a button right identifier list corresponding to the login account, where the button right identifier list includes all right elements for which the login account has a right. The database feeds back a query result to the server, and the server may feed back acquired right information (referred to as a right list in the figure), that is, the button right identifier list, as a parameter of a right initialization function of the client to the client; the client may execute the right initialization parameter and generate a right identifier list variable, that is, the client determines which rights the login account has; and the client may acquire a list of elements for which a right customized attribute is configured, that is, the client may acquire information about a right element that is on the website and has a right customized attribute. The client may call a right comparison function to determine information about a right element that is on the website but is not included in the right information, so as to perform rights control. 
         [0145]    In  FIG. 3 , the server and the database are shown separately, that is, the database may not be located on the server, but the database may be controlled by the server; or the database may be located on the server. 
         [0146]    Optionally, this embodiment of the present invention may be mainly applied to a web system. For typical implementation, generally Java programming language is used on a server, and HTML (Hypertext Markup Language)/JavaScript (network script language) is used on a client. The following describes the technical solutions of the present invention by using Java and HTML/JavaScript as an example. 
         [0147]    The client adds a right customized attribute mappingid to a right element, where the right customized attribute is assigned as a right identifier of a function point corresponding to the right element. 
         [0148]    A user logs in to a website by using a browser installed on the client, the user inputs login information, the login information corresponds to a login account, and the client sends the login information to the server. 
         [0149]    The server acquires right information of the login account from the database, stores the right information of the login account into a Session (session) of the user, and assigns the right information of the login account to the client by using a JSTL (JSP Standard Tag Library, JSP Standard Tag Library) tag, where generally the right information may be a right list and include a right that the login account has, that is, include information about each right element that the login account can operate. 
         [0150]    The client acquires the right information of the login account from the server by using the JSTL tag, and the client converts the right information into a client variable. 
         [0151]    For example, addprivilegeId is a right initialization function of the client, where the function divides incoming right information into arrays and saves the arrays to a JavaScript array variable privilegeMappingidList of the client. 
         [0152]    After a web page is completely loaded, the client acquires an right element for which a right customized attribute is configured, and calls a right comparison function (filterPrivilege). 
         [0153]    For example, a document.ready event definition function is used to acquire a list of right elements for which a right customized attribute mappingid is configured, and the list is transmitted to the right comparison function for processing. 
         [0154]    The right comparison function acquires a value of a right customized attribute of each right element and determines whether the value of the right customized attribute of each right element exists in the privilegeMappingidList array; if a value of a right customized attribute of one right element of the right elements exists in the privilegeMappingidList array, it indicates that the login account has operation right for the right element, and the right element can be displayed or enabled for the login account; if a value of a right customized attribute of one right element of the right elements does not exist in the privilegeMappingidList array, it indicates that the login account has no operation permission for the right element, and the right element is not displayed or enabled for the login account. 
         [0155]    Referring to  FIG. 4 , based on a same inventive concept, an embodiment of the present invention provides a client, where the client may include an acquiring module  401 , a sending module  402 , and a control module  403 . 
         [0156]    The acquiring module  401  may be configured to acquire login information input by a user. 
         [0157]    The sending module  402  may be configured to send the login information to a server, where the login information is used by the server to query right information corresponding to the login information. 
         [0158]    The control module  403  may be configured to receive the right information sent by the server, and control access right of a login account according to the right information, where the login account is an account corresponding to the login information.

         [0163]    a determining submodule, configured to determine the information about the right element included in each interface of the website or the application; a judging submodule, configured to determine, according to the right information, whether there is information about a right element, wherein the information is in the determined information about a right element but is not included in the right information; and a display forbidding submodule, configure to: when there is information about a right element that is not included in the right information, forbid displaying of the right element corresponding to the information about the right element that is not included in the right information. 
         [0164]    Optionally, in this embodiment of the present invention, that the control module  403  may be specifically configured to control the access right of the login account according to the right information is specifically: determining information about a right element included in each interface of the website or the application, determining, according to the right information, whether there is information about a right element that is in the determined information about the right element but is not included in the right information, and when there is information about a right element that is not included in the right information, forbidding enabling of the right element corresponding to the information about the right element that is not included in the right information. 
         [0165]    Specifically, in this embodiment of the present invention, the control module  403  may include: 
         [0166]    a determining submodule, configured to determine the information about the right element included in each interface of the website or the application; a judging submodule, configured to determine, according to the right information, whether there is information about a right element that is in the determined information about the right element but is not included in the right information; and an enabling forbidding submodule, configure to: when there is information about a right element that is not included in the right information, forbid enabling of the right element corresponding to the information about the right element that is not included in the right information. 
         [0167]    Referring to  FIG. 5 , based on a same inventive concept, an embodiment of the present invention provides a server, where the server may include a receiving module  501 , a querying module  502 , and a sending module  503 . 
         [0168]    The receiving module  501  may be configured to receive login information sent by a client and input by a user.

         [0171]    Optionally, in this embodiment of the present invention, the receiving module  501  may be specifically configured to receive the login information that is sent by the client and input by the user by using a login interface, where the login interface is a login interface of a website, or the login interface is a login interface of an application. 
         [0172]    Optionally, in this embodiment of the present invention, when the login interface is a login interface corresponding to a website, the right information corresponds to the website; or when the login interface is a login interface corresponding to an application, the right information corresponds to the application. 
         [0173]    Referring to  FIG. 6 , based on a same inventive concept, an embodiment of the present invention provides a client, where the client may be the client described above. The client includes: a bus  640 , and a processor  610 , a memory  620 , a receiver  630 , a transmitter  650 , and an input device  660  that are connected to the bus  640 , where: the memory  620  is configured to store an instruction; the input device  660  is configured to acquire login information input by a user; the transmitter  650  is configured to send the login information to a server, where the login information is used by the server to query right information corresponding to the login information; the receiver  630  is configured to receive the right information sent by the server; and the processor  610  is configured to execute the instruction, and control access right of a login account according to the right information, where the login account is an account corresponding to the login information. 
         [0174]    Optionally, in this embodiment of the present invention, the client may further include a display connected to the bus  640 . The display may be configured to display a login interface, where the login interface is a login interface of a website, or the login interface is a login interface of an application; the input device  660  may be specifically configured to acquire the login information that is input by the user by using the login interface. 
         [0175]    Optionally, in this embodiment of the present invention, when the login interface is a login interface corresponding to a website, the right information corresponds to the website; or when the login interface is a login interface corresponding to an application, the right information corresponds to the application. 
         [0176]    Optionally, in this embodiment of the present invention, the processor  610  is specifically configured to: execute the instruction; determine information about a right element included in each interface of the website or the application; determine, according to the right information, whether there is information about a right element that is in the determined information about the right element but is not included in the right information; and when there is information about a right element that is not included in the right information, forbid displaying of the right element corresponding to the information about the right element that is not included in the right information. 
         [0177]    Optionally, in this embodiment of the present invention, the processor  610  is specifically configured to: execute the instruction; determine information about a right element included in each interface of the website or the application; determine, according to the right information, whether there is information about a right element that is in the determined information about the right element but is not included in the right information; and when there is information about a right element that is not included in the right information, forbid enabling of the right element corresponding to the information about the right element that is not included in the right information. 
         [0178]    Referring to  FIG. 7 , based on a same inventive concept, an embodiment of the present invention provides a server, where the server may be the server described above. The server includes: a bus  740 , and a processor  710 , a memory  720 , a receiver  730 , and a transmitter  750  that are connected to the bus  740 , where: the memory  720  is configured to store an instruction; the receiver  630  is configured to receive login information sent by a client and input by a user; the processor  610  is configured to execute the instruction, and query, according to the login information, right information corresponding to the login information; and the transmitter  650  is configured to send the right information to the client, where the right information is used by the client to control access right of a login account, and the login account is an account corresponding to the login information. 
         [0179]    Optionally, in this embodiment of the present invention, the receiver  630  is specifically configured to receive the login information that is sent by the client and input by the user by using a login interface, where the login interface is a login interface of a website, or the login interface is a login interface of an application. 
         [0180]    Optionally, in this embodiment of the present invention, when the login interface is a login interface corresponding to a website, the right information corresponds to the website; or when the login interface is a login interface corresponding to an application, the right information corresponds to the application. 
         [0181]    In this embodiment of the present invention, the rights control method may include: acquiring, by a client, login information input by a user; sending, by the client, the login information to a server, where the login information is used by the server to query right information corresponding to the login information; receiving, by the client, the right information sent by the server, and controlling, by the client, access right of a login account according to the right information, where the login account is an account corresponding to the login information. 
         [0182]    In the embodiments of the present invention, the server can query, according to the login information, right information corresponding to a user and feed back the right information to the client, so that the client can control a right of the user, that is, the client controls the right of the user, which does not cause too much pressure on the server; after the right information is fed back to the client, the client can directly control the right of the user, and it is unnecessary to implant too much code; therefore, this implementation manner is simpler and more convenient for practical application. In addition, if the server controls the right of the user, the server is under too much pressure, and the server can control the right of the user only after the client transmits information to the server, which requires more control time; however, if the client directly controls the right of the user, time for information transmission is saved, and correspondingly control efficiency is improved. 
         [0183]    It may be clearly understood by a person skilled in the art that, for the purpose of convenient and brief description, division of the foregoing functional modules is taken as an example for illustration.
