Communication system building method and device based on websocket

Abstract

The invention provides a communication system building method and device based on websocket. The communication system building method based on the websocket comprises the following steps that a servercreates an app.js application program; the server quotes an express framework and an http framework in the aap.js application program; the server starts the http framework to monitor a port of the server; the server maps a url request and returns a request response, wherein the request response comprises an initial character string; a client enables a socket.io.js component; the client defines aninformation sending function and an information receiving function; the server quotes a socket.io framework in the app.js application program; the server replaces the initial character string with acharacter string on a page of the client; and the server defines a socket monitoring event in the app.js application program. According to the method and the device, the full-duplex communication application of the websocket is achieved through open source technologies such as NodeJS, Express and socket.io, and the method and the device do not depend on the version of an application server any more, and have the advantages of light weight, large flexibility and high transfer ability.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a method and device for building a communication system based on websocket. Background technique [0002] Websocket is a new protocol of HTML5, which realizes full-duplex communication between browser and server, can better save server resources and bandwidth, and achieve real-time communication. Since the advent of Websocket, the industry has not formed a unified specification. Each browser and application server manufacturer has its own implementation. Later, javaEE7 began to support websocket, and major application server manufacturers also began to support it. However, the existing technology has certain requirements on the version of the server. For example, IBM's WebSphere requires 8.0 or above, and Tomcat requires 7.0.5+. The application processing is relatively complicated.
