Abstract

A method, an apparatus and a system for invoking a local service component by a browser are provided. The method includes receiving, by a client terminal, a connection request based on a cross-domain communication protocol initiated by a browser terminal; performing, by the client terminal, validity verification of the connection request; and if the connection request passes the validity verification, establishing, by the client terminal, a communication connection with the browser terminal based on the cross-domain communication protocol to allow the browser terminal to invoke a local service component. The present disclosure can achieve an invocation of a local service component by most mainstream browsers, and has a better security of communications.

Claims

1. A method implemented by a client terminal, the method comprising:

receiving a request for establishing a communication connection based on a cross-domain communication protocol from a browser terminal;

performing validity verification of the request; and

establishing the communication connection with the browser terminal based on the cross-domain communication protocol to allow the browser terminal to invoke a local service component, after the request passes the validity verification.

2. The method of claim 1, further comprising selecting a port from a port list for binding according to a set port binding priority order upon receiving the request from the browser terminal, the port binding priority order being consistent with a port selection priority order of the browser terminal.

3. The method of claim 1, further comprising sending a breakdown report from the client terminal to a server when the client terminal breaks down.

4. The method of claim 3, further comprising obtaining the breakdown report by invoking a fault diagnostic program built in an operating system via an application programming interface of the operating system.

5. The method of claim 3, wherein the breakdown report comprises at least an error code, an error location, and a current state.

6. The method of claim 1, wherein the cross-domain communication protocol comprises a WebSocket protocol, a JSONP protocol, or a CORS protocol.

7. The method of claim 1, wherein the validity verification comprises determining whether a website corresponding to the browser terminal from which the request is received is a website included in a website white list.

8. The method of claim 7, further comprising updating the website white list by querying the server periodically.

9. The method of claim 1, further comprising:

receiving a command sent by the browser terminal;

parsing the command and delivering the command to a corresponding local service component;

receiving a processing result returned by the local service component after processing the command; and

forwarding the processing result to the browser terminal.

10. An apparatus comprising:

one or more processors;

memory;

a connection request reception module stored in the memory and executable by the one or more processors to receive a connection request based on a cross-domain communication protocol from a browser terminal;

a validity verification module stored in the memory and executable by the one or more processors to perform validity verification of the connection request; and

a connection control module stored in the memory and executable by the one or more processors to establish a communication connection with the browser terminal based on the cross-domain communication protocol to enable the browser terminal to invoke a local service component, if the connection request passes the validity verification.

11. The apparatus of claim 10, further comprising a port binding module to select a port from a port list for binding according to a set port binding priority order after the connection request reception module receives the connection request based on the cross-domain communication protocol from the browser terminal, the port binding priority order being consistent with a port selection priority order of the browser terminal.

12. The apparatus of claim 10, further comprising a breakdown report processing module to send a breakdown report to a server upon determining that the apparatus breaks down.

13. The apparatus of claim 12, wherein the breakdown report processing module acquires the breakdown report by invoking a fault diagnostic program built in an operating system via an application programming interface of the operating system.

14. The apparatus of claim 12, wherein the breakdown report comprises at least an error code, an error location, and a current state.

15. The apparatus of claim 10, wherein the cross-domain communication protocol comprises a WebSocket protocol, a JSONP protocol, or a CORS protocol.

16. The apparatus of claim 10, wherein the validity verification comprises determining whether a website corresponding to the browser terminal from which the connection request is received is a website included in a website white list.

17. The apparatus of claim 16, further comprising an update module to update the website white list by querying the server periodically.

18. A system comprising:

a browser terminal to initiate a connection request based on a cross-domain communication protocol to a client terminal; and

the client terminal to perform validity verification of the connection request, and establish a communication connection with the browser terminal based on the cross-domain communication protocol to enable the browser terminal to invoke a local service component, if the connection request passes the validity verification.

19. The system of claim 18, further comprising a server to receive and store a breakdown report sent by the client terminal.

20. The system of claim 19, wherein the breakdown report comprises at least an error code, an error location, and a current state.
