1, what is WebSocket? WebSocket is a natural full-duplex, bidirectional, single socket connection. Using WebSocket, your HTTP request becomes a single request to open a WebSocket connection (WebSocket or WebSocket over TLS (trans

. Once the payload length and masking key is decoded, you can go ahead and read that number of bytes from the socket. Let's call the data encoded, and the key MASK. To get decoded, loop through the octets (bytes a.k.a. Characters for text data) of encoded and XOR the O Ctet with the (i modulo 4) th octet of the MASK. In pseudo-code (so happens to be valid JavaScript): var decoded = "";for (var i = 0; i Decoded[i] = encoded[i] ^ mask[i% 4];}

Overview of WebSocket Technology in JavaScript HTTP is a stateless protocol. The server itself does not have the ability to identify the client. It must use external mechanisms, such as session and cookie, to maintain a conversation with a specific client. This is more or less inconvenient, especially when the server and client need to continuously exchange data (such as online chat. To solve this problem, HTML5 proposes the

LAPLACEDEMON/SJQ.Http://www.cnblogs.com/shijiaqi1066/p/3795075.html1 WebSocket and traditional web real-time communication technology1.1 WebSocketHTTP is a typical single-work mode. This is the Request/response-based approach to interacting with the server. HTML5 provides a duplex communication protocol

The reason why I write this article is that I think the more simple the technology can often play the more important role, with the birth of a variety of new technologies, real-time web technology has come into our. WebSocket and node. js make it easy to develop real-time applications with very high performance.About WebSocketWebSocket is HTML5 important feature, it directly in the browser with the socket support, which gives the web development unlim

/** * Initiates the WebSocket connection. This method is does not block. */public void Connect () {if (writethread! = null) throw new IllegalStateException ("Websocketclient objects is not Reusea Ble "); writethread = new Thread (this); Writethread.start ();}We can find:He actually started a thread because the websocketclient class implements the Runnable interface, so he's going to call the Run method on his own, and then we

So take the time today to record what you've learned recently. This article mainly analyzes the principle of WebSocket, and attaches a complete chat room combat Demo (including front and back end, code download link at the end of the text).2, WebSocket and HTT

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

With so many theories in front, let's take a look at code learning.Websocketapi Introductionfirst look at a simple JavaScript code that calls the WebSockets API.var ws = new WebSocket ("ws://echo.websocket.org"); Ws.onopen = function () {ws.send ("test!");}; Ws.onmessage = function (evt) {console.log (evt.data); Ws.close ();}; Ws.onclose = function (evt) {console.log ("websocketclosed!");}; Ws.onerror = function (evt) {console.log ("websocketerr

This chapter describes the life cycle of the websocket endpoint. The lifecycle of the WebSocket endpoint provides the developer with a framework to manage the resources needed for the endpoint, as well as a framework to intercept messages. We'll look at the sequence and semantics of their lifecycle, and how the Java WebSocket API provides APIs and annotations to

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
