Using the WebSocket interface in WorkermanWorkerman official website http://www.workerman.net/Suppose you now have a need to instantly update the list of people watching live(1) First establish a mapping table with the current process ID and the live video ID, as well as the u_id (user ID) and u_name (user name) fields in the table.(2) to

We have established a two-way communication between the server and the client, if you immediately drop the data according to previous experience, congratulations, the data can pass, but you do not know, it is natural, his site he wants to make the decision, WebSocket has its own agreed data format, We have to do it in this format.Protocol this thing, very boring, can only use, can not innovate, but more understanding of some of these rules, for the fu

Once you understand the connection between the network socket and the WEB server, you can send data from the browser to the server and receive the response data returned by the server.The following is an API for creating a new WebSocket object:Copy codeThe Code is as follows: var Socket = new WebSocket (url, [protocal]);Here, the first parameter refers to the URL to be connected, and the second parameter is

This chapter describes how to use the WebSocket API to control protocols and create applications, and using the existing WebSocket servers provided by http://websocket.org, we can send and receive messages, and create some simple websocket applications. Step-by-step learning to use the

principle and programming interface of WebSocket. The next step is to demonstrate how to implement a WebSocket application in a simple case, and to demonstrate how WebSocket is perfectly unified in both powerful and easy-to-use programming. Finally, this paper introduces the current situation, limitations and future p

Next, we will use a simple case to demonstrate how to implement a WebSocket application, and demonstrate how WebSocket is perfectly unified in terms of powerful functions and easy-to-use programming. Finally, the status, limitations, and future prospects of mainstream browsers for

One, WebSocket and HTTPTransferred from: https://www.cnblogs.com/tohxyblog/p/7112917.htmlWebSocket is the HTML5 (protocol), that is, the HTTP protocol does not change, or it does not matter, but HTTP is not support for persistent connection (long connection, not counting the loop connection)First of all, HTTP has, 1.1 and 1.0 it is called keep-alive , to merge multiple HTTP requests into one, but in Websocket
