http://www.oschina.net/translate/java-ee-html5-websocket-example?cmpHTML5 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.In this

In fact, I have been wondering why HTML5 wraps an application layer discussion as the basic purpose of socket adoption. In fact, directly supporting socket TCP is comparatively simpler and more flexible. since the standards have been developed and the browser also supports them, we can only use points for our developers. the latest version of websocket Protocol onIts standard specification has been clearly defined, So now can be developed according to

WebSocket defines two types of transport information: text information and binary information. The types are determined, but their transmissions are not specified. Therefore, it is necessary to use a simple text transfer type to specify

WebSocket 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-t

After the connection is established, the WebSocket data frame can be transmitted between the client and the server in full duplex mode. At the same time, both the text and binary frames can be sent in any direction, the minimum frame size is 2 bytes. In a text frame, each frame starts at 0x00 and stops at 0 x FF bytes, and the data is encoded in UTF-8. WebSocket text frames use Terminator, while binary fr
