An acquisition method for applet data, wherein the acquisition method is applied to a terminal, the method comprising: establishing a network connection with a data server according to an interface address of the data server corresponding to an applet when a trigger operation for starting the applet is detected; sending, to a service server, a loading event that is used to instruct the service server to load and start the applet; receiving, from the service server, a call request that is used to instruct the terminal to send a network connection request message to the data server; after receiving the call request, sending directly through the pre-established network connection a data request message to the data server through the network connection after the applet is started; receiving, from the data server, a data response message that contains requested data; sending a data processing request message to a service server corresponding to the applet, wherein the data processing request message contains the requested data and is used to instruct the service server to perform logical processing and rendering processing on the requested data; receiving, from the service server, a data processing response message that contains the requested data that has been processed; and displaying the requested data that has been processed; wherein the establishing a network connection with the data server according to an interface address of the data server corresponding to an applet comprises: sending, according to the interface address of the data server, a network connection request message to the data server, wherein the network connection request message is an empty request message; and receiving, from the data server, a network connection response message that is used to indicate that the network connection has been established. establishing a network connection with a data server according to an interface address of the data server corresponding to an applet when a trigger operation for starting the applet is detected; sending, to a service server, a loading event that is used to instruct the service server to load and start the applet; receiving, from the service server, a call request that is used to instruct the terminal to send a network connection request message to the data server; after receiving the call request, sending directly through the pre-established network connection a data request message to the data server through the network connection after the applet is started; receiving, from the data server, a data response message that contains requested data; sending a data processing request message to a service server corresponding to the applet, wherein the data processing request message contains the requested data and is used to instruct the service server to perform logical processing and rendering processing on the requested data; receiving, from the service server, a data processing response message that contains the requested data that has been processed; and displaying the requested data that has been processed; wherein the establishing a network connection with the data server according to an interface address of the data server corresponding to an applet comprises: sending, according to the interface address of the data server, a network connection request message to the data server, wherein the network connection request message is an empty request message; and receiving, from the data server, a network connection response message that is used to indicate that the network connection has been established. sending, according to the interface address of the data server, a network connection request message to the data server, wherein the network connection request message is an empty request message; and receiving, from the data server, a network connection response message that is used to indicate that the network connection has been established.
