Server:OK, well, I know, show you my ID card to prove it. Later, Sec-websocket

I have to service A, do not mistakeFinally, to Sec-WebSocket-Version tell the server to use the Websocket Draft (Protocol version), at the initial time, the WebSocket protocol is still in the Draft stage, all kinds of bizarre protocols have, and there are many strange things in the period, What Firefox and Chrome use

In HTML5 specifications, my favorite Web technology is the rapidly becoming popular WebSocket API. WebSocket provides a popular technology to replace the Ajax technology we have been using over the past few years. This new API provides a method to effectively push messages from the client to the server using simple syntax. Let's take a look at HTML5 WebSocket API

address this compatibility limit, such as: Open source Socket.io, see the Socket.io Introduction: Support WebSocket, web-side instant Messaging framework.6. SSE: Solutions for the Future 2SSE (server-sent event, server-side push events) is a HTML5 technology that allows the server to push new data to the client. This is a better solution than the client polling every few seconds to pull new data from the server.It can also push data from the server t

framework of python (tornado provides the tornado. websocket module ). Of course, you can also use socket. io is a js language server designed for webSocket. it is very easy to use and is compatible with browsers that do not support webSocket (implemented in flash or comet ). I personally prefer tornado, which has been used for background development for several

Then the string is SHA-1 algorithm encryption, get the length of 20 bytes of binary data, and then the data is BASE64 encoded, the end of the service side of the key, that is Ser_key. The handshake succeeded after the server attached Ser_key to the return value sec-websocket-accept.2.3 Dat

HTML5-WebSocket to achieve chat room example, websocket to achieve chat room The traditional way to implement chat rooms on Web pages is to request the server to obtain related chat information at intervals. However, the websocket function brought about by html5. because websocket allows a connection to the server for

Php + websocket Simple Chat Room practice, websocket Construction 1. Preface There is a simple chat room in the company's game. After learning about it, I learned that it was implemented by node + websocket. I think php will also be used as a simple chat room. As a result, I collected various materials to read documents and find instances. I also wrote a simple c

WebSocket and message push, WebSocket message push In B/S-structured software projects, sometimes the client needs to obtain server messages in real time, but the default HTTP protocol only supports the request response mode. This can simplify the Web server and reduce the burden on the server, the response speed is accelerated because the server does not need to establish a communication link with the clie

Use html5 websocket to implement a chat room. What is websocket? The WebSocket protocol is a new protocol introduced by html5. it aims to implement full duplex communication between browsers and servers. Those who read the link above will surely have some knowledge about how low efficiency and high consumption (polling or comet) have been done in the past. In th

First knowledge of WebSocket protocol, first knowledge of websocket1. What is the WebSocket protocol? RFC6455 is described as follows: The WebSocket Protocol enables two-way communication between a client running untrusted code in a controlled environment to a remote host that has opted-in to communications from that code. The security model used for this is the

connection, the connection can be two-way communication, and once the connection is established, there is no client service side of the communication between the two sides, providing the end-to-end communication. We can use this approach to build a desktop version of the IM program that allows users on different hosts to send messages. In essence, a socket is not a new protocol, it is simply a encapsulation of the TCP/IP protocol family communication

The WebSocket protocol is a two-way communication protocol that is based on TCP and transmits data over TCP as HTTP, but it differs from HTTP by a maximum of two points: 1. WebSocket is a two-way communication protocol, after establishing a connection, the WebSocket server and Browser/ua can actively send or receive data to each other, just like a socket, The dif

Function: Use websocket technology to display the log information on remote server in real time on the browser of operation and Maintenance toolIn general, we need to present the information in the deployment process in real time when the OPS tool is deployed, or show the program log to the developer in real time in the browser. Are you still using AJAX to get the server log every once in a while? Out, try the web
