1. Essentially differentAjax, asynchronous JavaScript and XML, is a Web development technique for creating interactive Web applications;WebSocket is HTML5 a new protocol that implements full-duplex communication between the browser and the server. The essence is to create a TCP connection for exchanging data after shaking hands with the HTTP/HTTPS protocol, and the server communicates with the client in real time through this TCP connection.2. Life cy

Yesterday, I learned the native instance of WebSocket, and found it necessary to compare several common client-server-side no-refresh interaction forms:First, Ajax: The client determines when to proactively send requests to the server sidesuch as: No refresh comments, no refresh change pictures.The primary purpose is to not refresh the customer experience, but it is the client's action to trigger a request

Recently participated in a LAN chat project. Use of the WebSocket. Here is a brief introduction.Sockets and WebSocketSimply saying that the relationship between sockets and WebSocket is the same as Java and JavaScript. Never mind.The Socket is a programming interface for transmitting data between the transport layer and the application layer in the TCP/IP protocol.WebSocket is a method based on asynchronous

, request: Servlet request. Like filters, the return value determines whether to intercept messages from the server to the browser. # Create a service named myservice. Groovy // The Listener annotation specifies the message that this method accepts. If namespace is not specified, all messages are accepted. Here, messages named browser group are accepted.// Note that the method name must be the Tag Name Defined in myevents. Groovy@ Listener (namespace = 'browser ') def msgtoserver (Map Data ){Pri

significantly improved for performance. In terms of consumption, the consumption on the server is certainly a little larger. After all, you have to Hold N links for N accesses. This fact is there. Compatibility is not considered. If you have high requirements on real-time performance, you can use websocket because the latency is much lower, such as message pushing and other functions. In addition, it is better to maintain a connection when frequ

. If you have a high demand for real-time, you can consider using WebSocket, because the delay is much lower, such as doing some message push functions, and frequent communication words to maintain a better connection. If you just do a query without timing, you should still use Ajax. Personal opinion, for reference only ~ Right, now both requirements exist, in order to improve the real-time can

In HTML5 specifications, my favorite Web technology is the rapidly becoming popular WebSocket API. WebSocket provides a popular technology to replace the Ajax technology we have been using over the past few years. This new API provides a method to effectively push messages from the client to the server using simple syntax. Let's take a look at HTML5

you need to be compatible with earlier versions of browsers, it is recommended to use reverse ajax or persistent connections; websocket can be directly used if it is a mobile client or non-modern browser is not required. It is not recommended to use Flash to push messages because it depends on plug-ins and does not support messages on mobile phones. There are also encapsulated plug-ins for reverse
