A method for executing a service operation by displaying a web page through a web browser, the method comprising: receiving, by a server and from a terminal device, a web page service request, wherein i) the web page service request is sent to the server from a browser on the terminal device, ii) the web page service request comprises a request for a web page that executes a corresponding service operation, and iii) the web page service request comprises multiple service parameters for executing the service operation; parsing, by the server, the web page service request to obtain the multiple service parameters, wherein the multiple service parameters comprise a service identifier and one or more of service type, transaction amount, payment channel, information about transaction parties, terminal device operating system, terminal device MAC address, terminal device network type; returning (S 102), from the server, to the terminal device and based on the web page service request, a web page comprising i) the service identifier and ii) code for waking up a designated application configured to initiate execution of the service operation, the code comprising an identifier of the designated application, wherein the browser on the terminal device i) does not integrate a software development kit of the designated application, ii) runs the web page to load the code included in the web page and iii) sends an instruction to the designated application to wake up the designated application using the identifier of the designated application included in the web page; receiving, by the server and from the application, a request for execution of the service operation, wherein the request for execution of the service operation corresponds to the web page service request, wherein the request for execution of the service operation is sent by the application based on the service identifier; and executing, by the server and the application, the service operation based on the request for execution of the service operation, wherein executing the service operation comprises i) returning, from the server, the service parameters to the application, wherein the application displays the service parameters to a user for confirmation, ii) receiving, by the server, confirmation information from the application, and iii) executing, by the server, the service operation based on the service parameters. receiving, by a server and from a terminal device, a web page service request, wherein i) the web page service request is sent to the server from a browser on the terminal device, ii) the web page service request comprises a request for a web page that executes a corresponding service operation, and iii) the web page service request comprises multiple service parameters for executing the service operation; parsing, by the server, the web page service request to obtain the multiple service parameters, wherein the multiple service parameters comprise a service identifier and one or more of service type, transaction amount, payment channel, information about transaction parties, terminal device operating system, terminal device MAC address, terminal device network type; returning (S 102), from the server, to the terminal device and based on the web page service request, a web page comprising i) the service identifier and ii) code for waking up a designated application configured to initiate execution of the service operation, the code comprising an identifier of the designated application, wherein the browser on the terminal device i) does not integrate a software development kit of the designated application, ii) runs the web page to load the code included in the web page and iii) sends an instruction to the designated application to wake up the designated application using the identifier of the designated application included in the web page; receiving, by the server and from the application, a request for execution of the service operation, wherein the request for execution of the service operation corresponds to the web page service request, wherein the request for execution of the service operation is sent by the application based on the service identifier; and executing, by the server and the application, the service operation based on the request for execution of the service operation, wherein executing the service operation comprises i) returning, from the server, the service parameters to the application, wherein the application displays the service parameters to a user for confirmation, ii) receiving, by the server, confirmation information from the application, and iii) executing, by the server, the service operation based on the service parameters. i) returning, from the server, the service parameters to the application, wherein the application displays the service parameters to a user for confirmation, ii) receiving, by the server, confirmation information from the application, and iii) executing, by the server, the service operation based on the service parameters.
