Web application security access method, server, and client

1. An application store server for web application security access, comprising:

a memory comprising instructions; and

a processor coupled to the memory, wherein the instructions cause the processor to be configured to:

periodically detect whether a first source code of a web application in the application store server is consistent with a second source code of the web application in a web server;

add an exception identifier to a version parameter of the first source code stored-on the application store server when the first source code is inconsistent with the second source code;

receive an access request for accessing the web application from a client, wherein the access request comprises a user version parameter for third source code for the web application installed on the client;

transmit prompt information to the client indicating a security risk in accessing the web application when detecting the exception identifier in the version parameter of the first source code and associated with the user version parameter;

send, to the client, a push message indicating that the second source code has changed, and in response, receiving from the client an operation instruction; and

execute the operation instruction on the web application, wherein the operation instruction causing to modify a second network address of the second source code to a first network address of the first source code stored on the application store server, thereby switching a network address of the web application to a secure version of the web application in the application store server.

2. The application store server according to claim 1 , wherein the instructions further cause the processor to be configured to:

store approved source code of the web application that is approved as the first source code; and

initialize the version parameter of the first source code on the application store server.

3. The application store server according to claim 1 , wherein the instructions further cause the processor to be configured to:

separately obtain, through calculation according to a preset hash algorithm, a first hash value corresponding to the first source code and a second hash value corresponding to the second source; and

determine, by means of comparison, whether the first hash value is equal to the second hash value; and

determine that the first source code is inconsistent with the second source code when the first hash value is not equal to the second hash value.

4. The application store server according to claim 1 , wherein the instructions further cause the processor to be configured to push, to the client, a push message indicating that the second source code displayed on the client has changed, wherein the push message comprises the operation instruction for confirmation by the client.

5. A web application security access method, comprising:

storing, by an application store server, approved source code of a web application as a first source code;

periodically detecting, by the application store server, whether the first source code of the web application in the application store server is consistent with a second source code of the web application in a web server;

adding an exception identifier to a version parameter of the first source code stored on the application store server when the first source code is inconsistent with the second source code;

receiving, by the application store server, an access request for accessing the web application from a client, wherein the access request comprises a user version parameter for a third source code of the web application installed on the client; and

transmitting, by the application store server, prompt information to the client indicating a security risk in accessing the web application when detecting the exception identifier in the version parameter of the first source code on the application store server and associated with the user version parameter;

sending, by the application store server to the client, a push message indicating that the second source code has changed and, in response, receiving, by the application store server, an operation instruction from the client; and

executing, by the application store server, the operation instruction causing to modify a second network address of the second source code to a first network address of the first source code stored on the application store server thereby switching a network address of the web application to a secure version of the web application in the application store server.

6. The web application security access method according to claim 5 , wherein the prompt information comprises information that indicates whether to continue to access the web application.

7. The web application security access method according to claim 5 , wherein the prompt information comprises changed content of the web application.

8. The web application security access method according to claim 5 , further comprising:

initializing, on the application store server, the version parameter of the stored first source code.

9. The web application security access method according to claim 5 , wherein periodically detecting, by the application store server, whether the first source code is consistent with the second source code comprises:

separately obtaining, through calculation according to a preset hash algorithm, a first hash value corresponding to the first source code and a second hash value corresponding to the second source code; and

determining, by means of comparison, whether the first hash value is equal to the second hash value; and

determining that the first source code is inconsistent with the second source code when the first hash value is not equal to the second hash value.

10. The web application security access method according to claim 5 , comprising, forwarding, by the application store server, the access request to the web server and receiving a response from the web server that subsequent access to the web application is allowed.

11. The web application security access method according to claim 5 , comprising, responding, by the application store server, to the access request using the first source code corresponding to the web application on the application store server.

12. The web application security access method according to claim 5 , further comprising:

periodically performing, by the application store server, virus detection on the second source code of the web application; and

prohibiting the client from accessing the web application in the web server when a virus is detected.
