Today, many Web sites are polled for the technology they use to implement push technology. Polling is at a specific time interval (such as every 1 seconds), the browser sends an HTTP request to the server, and then the server returns the latest data to the client's browser. This traditional pattern brings with it the obvious drawback that the browser needs to constantly make requests to the server, but the header of the HTTP request is very long, and the data contained in it may be a small value

As we all know, the HTTP protocol is stateless and interacts with the server based on Request/response, which is what we often call the single-mode. However, with the development of the Internet, the two-way communication between the browser and the server is increasing, and the way of long polling to the servers to get the latest data and push effect is becoming more and more satisfying. HTML5 Standard, also provides us with the browser and the service side of the Duplex Communication protocol

TCP/IP, WebSocket and MQTT
According to the OSI network layering model, IP is the Network layer protocol, TCP is the Transport Layer protocol, and HTTP and Mqtt are the application layer protocols. Between the three, TCP is the protocol for HTTP and Mqtt at the bottom. Everyone is familiar with HTTP, here is a brief introduction to MQTT. The MQTT (message Queuing Telemetry Transport, Messaging queue telemetry transmission) is an Instant Messaging pro
The HTML5 specification has brought us many new features on the basis of traditional web interaction, and these new features have been popularized and used as Web technology is widely used in web app development, and WebSocket as a new web communication technology is of great significance.What is a socket? What is WebSocket? What is the difference between the two? WebSo

The WebSocket protocol belongs to the HTML5 standard, and more and more browsers already natively support WebSocket, which enables two-way communication between client and server. After establishing a WebSocket connection on the client and server side, server-side messages can be sent directly to the client, thus breaking the traditional request-response mode and
The goal of the WebSocketWebSocket specification is to implement bidirectional communication with the server in the browser. Two-way communication can expand the application types on the browser, such as real-time data push (stock quotes), games, and chat. WebSocket protocol is a new HTML5 protocol ). It implements full-duplex communication between the browser and the server ). Currently, many websites use polling to implement real-time communication

Gmail turned out to be a native app-level experience based on front-end rendering that boosted the time and touched the user's G-spot relative to the previous service-side rendering of the Web page. Since then, the front-end rendering site has been the direction that countless developers are chasing.To better develop front-end rendering of "native-level" sites,

In PHP, developers need to consider more things, from the socket connection, establishment, binding, monitoring and so on all need the developer to complete the operation, for beginners, difficulty is also very large, so the idea of this article is as follows:
1, the socket agreement brief introduction
2. Introduce the connection principle between client and server
3, PHP set up the process of socket to explain
4, use a chat room as an example to expla
This article uses Swoole to implement PHP + websocket chat rooms. The process is detailed and helpful for the development of chat rooms. if you need it, you can refer to the study.

Websocket is only a network communication protocol
Just like http and ftp, they are all network communication protocols;
Compared with non-persistent protocols such as HTTP

The goal of WEB sockets is to provide full-duplex, bidirectional communication on a single persistent connection. After JavaScript creates a Web socket, an HTTP request is sent to the browser to initiate the connection. After the server response is obtained, the connection is switched from the HTTP protocol to the WebSocket protocol for the HTTP upgrade.Because WebSocket uses a custom

This allows you to use a third-party library, such as Frisbee or Axios, or you can request it directly using the XMLHttpRequest API.var New = (e) + = {if (request.readystate!== 4) {return; } if (Request.status = = =) { console.log (' success ', request. responsetext) ; Else { Console.warn
