2) installing the rear end of a browser plug-in at a computer terminal;
3) the service monitoring program is started automatically, whether the WebSocket server program is online or not is judged, and if the WebSocket server program is not online, the WebSocket server program is started;
4) a webpage of the Web browser calls a WebSocket client interface to initiate a service request;
5) the WebSocket client forwards the service request to the WebSocket server;
6) the WebSocket server analyzes the specific service request and calls a corresponding service middleware interface;
7) the service middleware calls a corresponding bottom layer function library interface to complete service response, and the service response is returned to the service middleware;
8) the service middleware forwards the service response to the WebSocket server;
9) the WebSocket server forwards the service response to the WebSocket client;
10) the WebSocket client interface returns a service response to the Web page.
Compared with the prior art, the invention has the advantages that:
1. the method is based on the widely popular WebSocket technology, has no hidden trouble of technology obsolescence and elimination for a long time, does not depend on a specific browser plug-in framework, and has no defect of poor compatibility of the traditional browser plug-in framework/technology;
2. the front end and the back end of the Web browser plug-in are separated, the front end and the back end process of the browser plug-in are isolated during the operation, the stability of the browser and the plug-in service is improved, the browser operation is not influenced when the back end of the browser plug-in is broken down, and the browser operation is not influenced when the browser is broken down;
3. the back end of the Web browser plug-in adopts a service framework of layered management, and is suitable for various application scenes according to different functions of a bottom function library integrated by coupling.
Drawings
Fig. 1 is a schematic structural diagram of a Web browser plug-in according to an embodiment of the present invention.
Detailed Description
The invention is further described below with reference to the drawings and specific preferred embodiments of the description, without thereby limiting the scope of protection of the invention.
As shown in fig. 1, the present invention provides a Web browser plug-in based on WebSocket, which implements data interaction between a browser and a background process/local device, and is composed of a WebSocket client, a WebSocket server, a service monitor, a service middleware, and a bottom-layer function library. The WebSocket client side is integrated to a Web browser webpage in a JS script mode, is used for forwarding service requests and responses by the front end of a browser plug-in and is operated on the background by the WebSocket server side, a service monitoring program, middleware and a bottom function library to form the rear end of the browser plug-in and is used for analyzing, forwarding and responding to the service requests.
