ajax websocket

Recently in a project to do need to use the WebSocket technology introduced in the HTML5, originally thought should be easy to fix, who knows in the real development after the discovery of a lot of trouble, although we are a front-end development and design of the team, And as a second-hand program apes are not to be seen for a long time, but in order to have the same needs of friends less detours, I decided to put the implementation method affixed to

WebSocket protocol is a new protocol for HTML5. It implements browser-to-server full-duplex communication (Full-duplex).The first handshake needs to be done with an HTTP request.The WebSocket is implemented based on TCP:Wikipedia:https://en.wikipedia.org/wiki/WebSocket https://html.spec.whatwg.org/multipage/comms.html#network :The server side can refer to the PH

a · What is WebSocketThe WebSocket protocol can communicate more than once after a successful handshake from the HTTP protocol until the connection is closed. However, the handshake in WebSocket is compatible with the handshake in HTTP, which uses the Upgrade protocol header in HTTP to upgrade the connection from HTTP to WebSocket. This makes it easier for the

We have introduced WebRTC and read the example of https://apprtc.appspot.com/on the Internet (which may need to be accessed through a wall). This example is an application deployed on the Google App Engine and relies on the Gae environment, the background language is Python and also relies on the Google App Engine channel API. Therefore, it cannot be run locally or be expanded. After studying the Python source code in the example, I decided to implement it in Java. After Tomcat 7, I started to s

The distribution of Message Centers is achieved through establishing a persistent connection between websocket and the backend server. The advantage of this method is to save network bandwidth, second, users can receive messages sent from the backend in real time. netty is used in the backend implementation. After stress testing, each server can withstand 0.5 million persistent connections, that is, 0.5 million users at the same time (only one persist

Socket. io can provide programmers with the same programming experience on the client and server. socket. io supports any browser and any Mobile devices. Next, I will explain to you through this article HTML5 WebSocket entry 3-Communication Model socket. io. If you need it, refer to socket. io. Why is it born? See the following description. Why socket. io? Node. js provides an efficient server running environment, but the browser supports HTML5 diffe

JS provides an efficient server-side runtime environment, but thanks to the browser-side support for HTML5, the Socket.io was born to provide a superior real-time user experience for all browsers, and to provide programmers with a consistent programming experience for

WebSocket protocol is a new protocol for HTML5. It implements browser-to-server full-duplex communication (Full-duplex).Browsers and servers 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. In this WebSocket agreement, there are two major benefits to our Instant service: 1. Headers that comm

The WebSocket technology introduced in HTML5 needs to be used in a project recently, which was supposed to be easily handled, who knows that there are a lot of troubles after the development is really started? Although we are a long-experienced team in development and design, we have never been seen as a second-hand programmer for a long time, however, I decided to stick the implementation method here to reduce detours for my friends who have the same

WebSocket Protocol:WebSocket protocol is a new protocol for HTML5. It is the implementation of browser-to-server full-duplex communication (Full-duplex). HTML5 defines the WebSocket protocol to better conserve server resources and bandwidth and to achieve real-time communication.We know that the traditional HTTP protocol is stateless, each request must be initiated by the client (such as a browser), the ser
