websocket tutorial

Before we introduce the main body, let me introduce the background and principle of websocket: Background In the browser can only achieve one-way communication through HTTP, comet can simulate two-way communication to some extent, but the efficiency is low, and need the server to have better support; The sockets and Xmlsocket in Flash enable true two-way communication, and you can use these two features in JavaScript with Flex Ajax Bridge. It can be

that it was not very suitable for the current project (maybe I just don't know how to implement it). Later learned that websocket, the Internet read a lot of documents are similar to chat room scenes, some different. In this, I mainly focus on the introduction of the server under the active push , by the service side to trigger. WebSocket main achievable scenarios: 1, web chat room 2, Server message real-t

WebSocket Real-time refresh of front-end pages when database updates are implemented javaweb directory (?) [+] userjsp Managerservletjava Title, to achieve the above functions, I know there are two major ideas: Polling: Polling is the principle of sending a request to the server over a period of time, which is not described here. Here is a discussion of the second way of thinking.

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

This article mainly introduces a simple WebSocket server that is compatible with the old and new Socket protocols in Python, if you need it, you can refer to the WebSocket technology introduced in HTML5 that needs to be used in a recent project. I thought it would be easy to handle it, who knows that there are a lot of troubles after the development is really started? although we are a long-experienced team

First, WebSocket Introduction:When it comes to web real-time push, you have to say websocket. Before the advent of WebSocket, a number of sites were typically used to implement real-time push technology.is polling (Polling) and comet technology, comet can be subdivided into two implementations, one is the long polling mechanism, which is called the flow technolog

WebSocket initiates a single request, the server does not need to wait for the customer service side, the client at any time can also send messages to the server, reducing the delay in polling time. The difference between polling and WebSocket. Once the resume is connected, the server can send the client multiple times.HTTP-based real-time messages are quite complex, and the state of maintaining a reply in

Recently in a project to use the HTML5 introduced in the WebSocket technology, I thought it should be easy to handle, 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 have long been not to be seen, but in order to have the same needs of friends to take a few detours, I still decided to put the implementation of the method in this

In HTML5, the Web Socket APIassociated with data communication is invoked to enable the push of information from the server to the client.Socket, also known as socket, is a technology that develops two-way communication in a TCP interface based on the standard. Typically, the socket is used to describe the IP address and port, which is a character handle in the communication process. When the server side and multiple application services bind a socket, the different ports correspond to different

I was very interested in seeing html5 websocket in my previous blog. I can finally get rid of long polling. (For the implementation method before websocket, I can refer to an article on Developer Works, at the same time, I also talked about the basic concepts of websocket. What is websocket

WebSocket is a network technology for Full-duplex communication between browsers and servers that HTML5 has started to provide. In the WebSocket API, the browser and the server only need to do a handshake (handshaking) of the action, then the browser and the server between the formation of a fast path. The data can be transmitted directly between the two. WebSocket
