websocket service

implementation has its own set of APIs, where we do not go into detail WebSocket concrete implementation, I can not speak, at least not now.Here we use the more accessible node. JS's Socket.io to do the communication framework,Socket.io to make long-connected communication is very simple, the server can no longer wait for the client's request to send a message directly to the client, According to this characteristic, the data communication synchroniz

transmitted on a TCP connection, so it is still the request/response message pair, which will cause the waste of resources and the problem of not being strong in real time.If it is not a continuous connection, that is, a short connection, then each resource to establish a new connection, the HTTP underlying use of TCP, then each time to use a three-time handshake to establish a TCP connection, that is, each request corresponding to a response, will cause great waste of resources.Long polling, t

Today research websocket time, found online many websocket+php demo is to enter the command line Php-q xxx.php to start the server, I am not very familiar with PHP, I would like to ask the following this scenario can be achieved? The browser Ajax request creates the Socket--> server to receive and establish the socket, which returns the socket address and port, The browser receives the socket address and p

Knowing HTML5 's websocket in the HTML5 specification, my favorite Web technology 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

In PHP, developers need to consider more things, from the socket connection, establishment, binding, monitoring and so on all need the developer to complete the operation, for beginners, difficulty is also very large, so the idea of this article is as follows: 1, the socket agreement brief introduction 2. Introduce the connection principle between client and server 3, PHP set up the process of socket to explain 4, use a chat room as an example to expla

Description:The two lines are peer2 as sever output, and the middle three lines are output as client side. The following is an analysis of client-side output: A peer-to-peer message sent to 7001: The client opens a message sent by the server: The server begins to receive the message sent by the server: Received message When the client side executes the Connect () method, Peer2 successfully connects to the OnOpen method of the peer1 that triggers both ends of the connection (the server and clie

This article outlines The goal of WEB sockets is to provide full-duplex, bidirectional communication on a single persistent connection. After JavaScript creates a Web socket, an HTTP request is sent to the browser to initiate the connection. After the server response is obtained, the connection is switched from the HTTP protocol to the WebSocket protocol for the HTTP upgrade.Because WebSocket uses a custom

Recently I encountered JavaScript cross-domain problem in the project, the parent page and the child page to communicate, and the parent-child page cross-domain, how to do?Everyone combined with previous experience, think of websocket,websocket client programming is relatively simple, the server we use Java implementation,To ensure that parent-child page communication is a peer-to-peer project, it is necess

This article uses Swoole to implement PHP + websocket chat rooms. The process is detailed and helpful for the development of chat rooms. if you need it, you can refer to the study. Websocket Websocket is only a network communication protocol Just like http and ftp, they are all network communication protocols; Compared with non-persistent protocols such as HTTP
