The problem with HTTP protocols – the connection was not duplex. The communication was unidirectional. At any point in time, either the client can send a request to the server or the server can respond. 当你获取 Web Socket 连接后，你可以通过 send() 方法来向服务器发送数据，并通过 onmessage 事件来接收服务器返回的数据。 以下 API 用于创建 WebSocket 对象。 var Socket = new WebSocket(url, [protocol] ); 以上代码中的第一个参数 url, 指定连接的 URL。第二个参数 protocol 是可选的

The html5 webpage connects to a local port that allows a web socket connection (use Flask/tornado). The C++ application connects to a UDP 

最近关于HTML 5 Web Socket的流言已经满天飞，它通过Web上的一个单一Socket定义了一个全双工通信信道，HTML 5 Web Socket并不是普通HTTP通信的增强版，它代表着一个巨大的进步，特别是针对实时的、事件驱动的Web应用程序。 Google的工程师Ian Hickson说“数据的字节数急剧减少到2字节，延迟从150毫秒减少到50

How to Use Sockets in JavaScript/HTML? There is no facility to use general-purpose sockets in JS or HTML. It would be a security disaster, for one. There is WebSocket in HTML5. The client side is fairly trivial: Copy above code and create HTML file, socket_client.html. After that execute following commands. nohup php -q socket_server.php & Above command will start your socket server. Now open HTML file in browser and it will connect to socket server. You are all set to use you PHP socket server.

The HTML5 WebSockets specification defines an API that enables web pages to use the WebSockets protocol for two-way communication with a remote host. It introduces the WebSocket interface and defines a full-duplex communication channel that operates through a single socket over the Web. HTML5 WebSockets provide an enormous reduction in unnecessary network traffic and latency compared to the unscalable polling and long-polling solutions that were used to simulate a full-duplex connection by

14 Nov 2012 In the world of HTML5 development, interoperability is king. Unfortunately, sometimes interoperability can be at the expense of performance. Websockets are great for maintaining a server/client relationship without as much of the overhead of HTTP web traffic. Today, websockets are used to build a  It shows that it is possible to create a HMI in HTML5 for a Command & tag, web workers, web sockets but the focus lies on evolving the HTML platform.[2, p.6-7]. From this point on, the client and server have a direct, socket connection and can freely I have an HTML5 page consisting of some JavaScript references. 0 onwards, you can use HTML5 WebSockets to exchange messages with the broker from your browser. HTML 5 introduced web sockets, as a standardized way to
