ajax websocket

The Socket.io encapsulates the WebSocket and includes other ways of connecting, such as Ajax. The reason is that not all browsers support WebSocket, and through the Socket.io package, you don't have to worry about what connection is being used. You can use Socket.io in any browser to establish an asynchronous connection. Socket.io contains the server side and the

The following figure shows the handshake between the client and the server when a websocket connection is established. This part can be easily completed in node, because the net module provided by node has encapsulated socket sockets, developers only need to consider data interaction instead of connection creation. Php does not, from socket connection, establishment, binding, listening, etc., all of which need to be operated by ourselves, so it is nec

Most websites use HTTP Communication, while HTTP is a connectionless protocol. Only when the client requests, the server can send a corresponding response, and the HTTP request package is also relatively large. If it is only a small data communication, the overhead is too large. So, we can use websocket this specific websocket introduction visible http://zh.wikipedia.org/wiki/

Websocketdemo WebSocket How to implement the Android client. introduce If you do not want to understand the principle can be directly pulled to the end of the use of the chapter, according to the tutorial can be used, or directly open the demo view Code, code address:.Https://github.com/0xZhangKe/WebSocketDemo This article uses a background service to establish a WebSocket connection, and the activity and

This article mainly introduces the example of using websocket in php. If you need a websocket connection, you can refer to the figure below to demonstrate the handshake between the client and the server, this part can be easily completed in node, because the net module provided by node has encapsulated socket, developers only need to consider data interaction instead of connection creation. Php does not, fr

HTTP/WebSocket and httpwebsocketHttp Definition HTTP is a standard TCP protocol for client and server requests and responses.HTTP request format The HTTP request format consists of the request line, request header, empty line, and message body. Each part occupies one line. Request Line: The request line is the first line of the request message. It consists of three parts: the request method (GET/POST/DELETE/PUT/HEAD) the URI path of the requested res

Review the previous chapterIn the previous chapter, "Why do we need HTML5 WebSocket", I briefly introduced the next WebSocket of the past life. I believe that we have a preliminary understanding of the websocket. So today we continue to study the mechanism of websocket in depth.WebSocket mechanismWe know that

Previously mentioned that LUA and NODEJS use socket communication, but because of the service-side constraints, eventually still chose the luasocket.Now, in the face of a new project, I naturally chose WebSocket.Therefore, I need to understand the following questions: What are the differences and connections between sockets and WebSocket? What's the relationship between WebSocket and HTML5?

high degree of freedom of customization, data privacy and other aspects of consideration, the final server-client end is self-implementation, the server uses the worker man's PHP socket architecture.On long-connected bidirectional communication, the WebSocket protocol is selected. Development is mainly responsible for the development of iOS client side, in accordance with the development of the third-party SDK standard, the key parts are encapsulated

Add the websocket module to skynet and skynetwebsocket Recently, I became fascinated by skynet, with a high code quality and outstanding computing in open-source game server frameworks, whether it's Python firefly, C ++/Python's kbengine, C #'s scut, or nodejs's pomelo, skynet has great advantages in concurrency and commercial applications. Recently, I have been playing h5 games. tornado/django is more than enough. I plan to try skynet in the next gam

Real-time push technology in the web domain is also called realtime technology. The purpose of this technology is to allow users to get real-time updates without having to refresh their browsers. It has a wide range of application scenarios, such as online chat rooms, online customer service systems, commenting systems, WEBIM, etc.Pan TigerLinks: https://www.zhihu.com/question/20215561/answer/26419995Source: KnowOriginal address: http://www.plhwin.com/2014/05/28/nodejs-socketio/

polling, the advantage of background polling is that the foreground does not have to send the request to the background, but wait until the background to find the data updated to remind the foreground to re-request data. This will require the use of websocket.The HTTP connection we normally use is the only client that can send requests to the server.The most important feature of WebSocket is that the server can actively push information to the client

Polling: The client periodically sends an AJAX request to the server, returning the response information and closing the connection as soon as the server receives the request.Pros: It's easier to write back-end programs.Cons: Half of the requests are useless, wasting bandwidth and server resources. (and each HTTP request and response has full HTTP header information, which increases the amount of data that is transmitted each time)Example: suitable fo

Most sites use HTTP protocol communication. HTTP is a non-connected protocol. The server-side talent sends a corresponding response only when the client is requested. the HTTP Request package is also larger, assuming only very small data traffic. Too much overhead. As a result, we are able to use the websocket Protocol to implement connection-oriented communication with minimal overhead. Detailed websocket
