This is the Request/response-based approach to interacting with the server. HTML5 provides a duplex communication protocol

Today research websocket time, found online many websocket+php demo is to enter the command line Php-q xxx.php to start the server, I am not very familiar with PHP, I would like to ask the following this scenario can be achieved? The browser Ajax request creates the Socket--> server to receive and establish the socket, which returns the socket address and port,

The development of web technology over the past few days can be described as a revolutionary development, not only limited to the ajax asynchronous refresh layer of web. I personally think that the technologies that can bring revolutionary significance after HTML5 mainly lie in the support of WebGL and local operations. However, the development of web not only exists with clients, but also changes in server technologies, such as

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

First to introduce Webscoket, actually started I do not know what is, so searched for a bit:WebSocket protocol is a new protocol for HTML5. It is the implementation of browser-to-server full-duplex communication (Full-duplex).Many web sites are now polling (polling) for instant messaging. Polling is at a specific time interval (such as every 1 seconds), the browser sends an HTTP request to the server, and the server returns the latest data to the client's browser. This traditional HTTP request p

The most important feature of using WebSocket to connect to a server is the feature of persistent links.Common points are: all are based on the TCP protocol Client-server link, WebSocket is HTML5 proposed a set of gaps in the HTTP link is not persistent link features (except long connection, long polling)Polling (AJAX): Refers to the browser-side timed to send th

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

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

Part III: Network protocolsWebSocket is an advanced network protocol developed to improve the performance of the network and the response rate of Web applications, we will introduce Netty support for these two features websocket, and we will give a simple example to explain the features of the two WebSocketIn the 12th chapter, you will learn how to use WebSocket to realize the function of bidirectional tran

, and need an efficient and energy-saving bidirectional communication mechanism to ensure the real-time transmission of data. In this context, the WebSocket, which is based on the HTML5 specification, is called the Web TCP . Early HTML5 did not form an industry-uniform specification, and each browser and application server vendor had a similar implementation, such as the Mqtt of IBM, the Comet Open source framework, and so on. Until 2014, HTML5 finall

IntroducedWebSocket is a network technology that HTML5 started to provide full duplex communication between the browser and the server. In the WebSocket API, the browser and server only need to do a handshake, and then a fast channel is formed between the browser and the server. The data can be transmitted to each other directly between the two.The Cocos2d-x engine integrates libwebsockets, and encapsulates an easy-to-use interface on the basis of Lib

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

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
