1. OverviewWebSocket is created to meet the growing demand for real-time communications based on the Web. In the traditional Web, in order to achieve real-time communication, the common way is to use the HTTP protocol to continuously send requests. However, this means wasting bandwidth (HTTP HEAD is relatively large) and consuming server CPU (no information is required to accept requests). (from websocket.org)Instead of using WebSocket technology, the

1. What is websocket?API Websocket API is the asynchronous communication method of the Next Generation client-server. This communication replaces a single TCP socket. It uses ws or WSS protocol and can be used for any client or server program. Websocket is currently standardized by W3C. Websocket has been received by

1, WebSocket introduction WebSocket is a protocol for Full-duplex communication provided by HTML5, typically a communication between a browser (or other client) and a Web server. This makes it suitable for highly interactive Web applications, such as timely communication chats. The websocket protocol is a new network protocol based on TCP. It implements the brow

The > ' WebSocket ' protocol enables full-duplex communication at the front and back end, replacing long-polling for wasted resources. On the basis of this protocol, the front-end data, the multi-data, real * * Real-time response can be realized. In the course of learning ' WebSocket ', a simplified version of Group chat was implemented, with detailed documentation of the process and code in this article. *

1.websocket Introduction In the past, the browser wanted to get the server data by sending an HTTP request and then waiting for the server to respond. That is, the browser side has always been the initiator of the entire request, only if it is active, to obtain data. To allow the browser side to get real-time data on the server side, it is necessary to constantly initiate requests to the server. Although the actual data has not been obtained in
