Objective web开发It also explains chapter three, which begins with a discussion of knowledge related to front-end communication. Implementation of an online chat room similar to the function or back-end push message to the front, in the absence WebSocket of the university that the group has been contacted DWR(Direct Web Remoting) , but also used polling method, when Servlet3.0 it comes out, also use its asynchronous connection mechanism for the fr

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

Introduction:Prepare some HTML5 new technologies to enhance the project tools. The design background interaction part selects HTML5 websocket, studies the basic usage, and wants to write some feelings about websocket practices. I personally think that the emergence of websocket is an innovation in Web application interaction design. Before

technique . This child sounds a lot bigger. is actually hiding a iframe tag, and then place this iframe src The property is set to a request for a long connection, and the server can continuously enter data to the client. But there is an obvious problem with this approach, and each browser will always show the page loading is not complete, and if the user is obsessive, he will turn off the page in minutes. TAT ... Forever IFRAME Technology 　　no matter what

This article mainly introduces WebSocket in HTML5. This article explains what WebSocketAPI is in HTML5, how to use WebSocketAPI in HTML5, and how to use WebSocketAPI with Socket. IO WebSocket, NodeJS, and Socket. i/O joint development and other content. For more information, see Understand HTML5 WebSocket In HTML5 specifications, my favorite Web technology is th

Websocket is an important feature of HTML5 and provides two-way communication between the client and server. It is the first choice for many webapps for network communication, but it is not supported in Android WebKit, the socket. i/O popularity. Of course, this feature cannot be missed in our cloud OS. My task this week is to support websocket in the cloud OS WebKit so that webapps can directly call the

Before we introduce the main body, let me introduce the background and principle of websocket: Background In the browser can only achieve one-way communication through HTTP, comet can simulate two-way communication to some extent, but the efficiency is low, and need the server to have better support; The sockets and Xmlsocket in Flash enable true two-way communication, and you can use these two features in JavaScript with Flex Ajax Bridge. It can be

that it was not very suitable for the current project (maybe I just don't know how to implement it). Later learned that websocket, the Internet read a lot of documents are similar to chat room scenes, some different. In this, I mainly focus on the introduction of the server under the active push , by the service side to trigger. WebSocket main achievable scenarios: 1, web chat room 2, Server message real-t

Here is a discussion of the second way of thinking.

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

1. Introduction HTML5 brings the ability of a full-duplex TCP connection WebSocket a standard server to a Web browser.In other words, the browser is able to establish a connection with the server, sending and receiving data through the established communication channels without the need for additional overhead to be introduced by the HTTP protocol.WebSocket offers a popular technology to replace the AJAX technology we've been using for the past few ye

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 browser receives the socket address and p

Objective When the video stream is pushed, the rtmp will have a delay of 3 seconds. At present, one solution is to resolve it in a Mpegts format. If you consider using FFmpeg to push the flow, you can use the HTTP format and UDP format to push the stream. The thing to do now is to forward the rtmp to the WebSocket interface with Netty, and then play with H5. The playback plugin is implemented using the JSMPEG project. "FFmpeg push Mpegts" The FFmpeg

Working with WebSocket technology, the use of the process found that the browser (Chrome) after the upgrade may cause the WebSocket is not available, the browser can be changed after the normal use.Once in a while, it is occasionally possible to debug locally, discovering that using the same version of the Chrome browser does not connect to the WS service on the online server, but can connect to the local W
