websocket connection

Create a websocket server instance with python, and share the websocket with python. I. Start Using python to implement websocket server, you can display the log information of the remote server in real time on the browser. A web Version Release System was developed before, but the system did not view logs online. After each release, You need to log on to the ser

What is WebSocket? WebSocket is a persistent protocol, which is relative to HTTP non-persistence. to give a simple example, The life cycle of http1.0 is defined by the request, that is, a request, a response, for HTTP, this time the client and server session to this end, and in http1.1, slightly improved, that is, the addition of keep-alive, that is, in a Multiple request requests and multiple response acce

/'); Script> Body>HTML>EntirecodeSecondly, the callback function is used to listen to the corresponding event and deal with it. There are altogether four monitoring events:　1. Onpen: triggered when the request succeeds　　2. OnClose: triggered when the request is closed　　3. onerror: triggered when an error occurs during a request or connection　　4. onMessage: triggered when a message is sent by the receiving serveralso, when a request is sent, the

transmission in a socket connection, the heartbeat message needs to be sent to maintain the connection ~ ~ The specific heartbeat message format is defined by the developer. WebSocket WebSocket is a network technology for Full-duplex communication between browsers and servers that HTML5 has started to provide. The

subscriptions and publications in the cluster Using the spring framework for subscriptions and publishing within this app is easy. As our systems become more complex, we need to post messages to other apps. This study will give you a websocket for ordering and publishing messages between different apps. In a small example, we establish a websocket connection bet

transport layer's TCP, there are more problems. I believe everyone who has created the wheel will feel it. Even if HTTP is used, problems such as performance, network latency, and reverse notification (the server actively notifies the client) occur. Therefore, WebSocket has emerged to solve this series of problems within a certain range. Use Directly go to the Code to show how to use WebSocket C ++ code (s

Objective HTML5 WebSocket realizes the two-way communication between the server and the browser, the bidirectional communication makes the server message push development simpler, the most common is the instant communication and the high demand for the real-time information. Most of the previous server message tweets used "polling" and "long Connection" technologies, both of which have considerable overhea

HTML5 has many notable new features, such as Canvas, local storage, multimedia programming interfaces, WebSocket, and so on. Although everyone is very enthusiastic about it, I personally think it requires the support of other platforms to truly "fire ". I used to explain in detail other methods such as ajax-based "polling" and "long polling" during web communication. Round robin: This is the earliest solution to implement real-time Web applications.

side.Both of these technologies are based on the request-response model, which is not really real-time technology; Each request and response wastes a certain amount of traffic on the same header information, and the complexity of the development is greater.With the launch of the HTML5 WebSocket, the real real-time communication of the web, so that b/s model with the C/s mode of real-time communication capabilities.

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
