websocket service

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

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

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

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
