One, WebSocket and HTTPWebSocket is the HTML5 (protocol), that is, the HTTP protocol does not change, or it does not matter, but HTTP is not support for persistent connection (long connection, not counting the loop connection)First of all, HTTP has, 1.1 and 1.0 it is called keep-alive , to merge multiple HTTP requests into one, but in Websocket fact a new protocol, with the HTTP protocol basically does not

WebSocket is a protocol in the HTML5 that supports persistent connections, while the HTTP protocol does not support persistent connections.First of all, HTML5 refers to a series of new APIs, or new specifications, technologies. WebSocket is a new protocol and new API in HTML5.The HTTP protocol itself is only 1.0 and 1.1, the so-called keep-alive, merging multiple HTTP requests into one.Second,

Socketis the intermediate software abstraction layer that the application layer communicates with the TCP/IP protocol family, which is a set of interfaces. In design mode, the socket is actually a façade mode, it is the complex TCP/IP protocol family hidden behind the socket interface, for the user, a set of simple interface is all, let the socket to organize data to meet the specified protocol. The previous chapters we talked about the difference between the socket and HTTP, to understand the s

method restrictions on @onmessage annotations differ. It is also further explained that the WebSocket specification is a rapidly changing norm. there is a direct compile time error, and some run-time errors. (It may be related to my choice of different versions of the development tools, not quite sure, the same code, behaves differently, odd)It is important to note that the three methods that are annotated by OnMessage receive different message types

This chapter describes the life cycle of the websocket endpoint. The lifecycle of the WebSocket endpoint provides the developer with a framework to manage the resources needed for the endpoint, as well as a framework to intercept messages. We'll look at the sequence and semantics of their lifecycle, and how the Java WebSocket API provides APIs and annotations to

, and need an efficient and energy-saving bidirectional communication mechanism to ensure the real-time transmission of data. In this context, the WebSocket, which is based on the HTML5 specification, is called the Web TCP . Early HTML5 did not form an industry-uniform specification, and each browser and application server vendor had a similar implementation, such as the Mqtt of IBM, the Comet Open source framework, and so on. Until 2014, HTML5 finall

My favorite Web technology in the HTML5 specification is the WebSocket API that is rapidly becoming popular. WebSocket offers a popular technology to replace the AJAX technology we've been using for the past few years. This new API provides a way to effectively push messages to the server from the client using simple syntax. Let's take a look at HTML5 's websocket
