How to build a websocket?
The first step is to compile a simple jsp file, which mainly includes websocket connection and four websocket response events.
Step 2: configure the struts. xml
"receive /app/change-notice the value sent, and then forward the value to the /topic/notice client."
/topic/noticeis an address that is specified when the client initiates a connection, subscribes to the server's message, and is used to receive the return of the server, which we will see when we write the client code.
So far, the service-side code coding finished! Next article we will write the client function.Wen/devid (author of Jane's book)Original link: http://www.jianshu.com

What is websocket?
The WebSocket protocol is a new protocol introduced by html5. it aims to implement full duplex communication between browsers and servers. Those who read the link above will surely have some knowledge about how low efficiency and high consumption (polling or comet) have been done in the past. In th

Concept As a next-generation Web Standard, HTML5 has a number of compelling new features, such as canvas, local storage, multimedia programming interfaces, WebSocket, and so on. Today we'll take a look at the WebSocket, which is called "Web TCP." The emergence of WebSocket is based on the real-time needs of Web applications. This kind of real-time web application
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
In PHP, developers need to consider more things, from the socket connection, establishment, binding, monitoring and so on all need the developer to complete the operation, for beginners, difficulty is also very large, so the idea of this article is as follows:

The example of using websocket in php is described in detail. The following figure shows the handshake between the client and the server when a websocket connection is established. This part can be easily completed in node, because the net module provided by node below I drew a figure to demonstrate the handshake part of the websocket connection between the clien
Here I draw a diagram showing the handshake part of the WebSocket connection between the client and the server, which can be done very easily in node, because the net module provided by node has already encapsulated the socket socket, and developers only need to use Consider the interaction of the data without having to deal with the establishment of the connection. and PHP does not, from the socket connection, establishment, binding, monitoring, and

To achieve the goal of this article, it is necessary to directly realize the function of chatting, and, on the basis of the chat function, and then realize the function of the cache chat record. The first step: the principle of chat implementation first, we need to clarify our needs. Usually, the chat on the Web page is the form of the chat room, so, this example also has a chat space concept, as long as in this space, you can chat together. Secondly, everyone can speak and be seen by others, so
