Recently, when using Ratchet (a PHP websocket framework) to transform a PHP Web site, an error occurred: "It is set to 1024x768, but you had descriptors numbered at least as high as 1266. --ENABLE-FD-SETSIZE=2048 is recommended, and may want to set itTo equal the maximum number of open files supported by your system " After several twists and turns, the reason is that the PHP source code set Fd_size to 1024, once more than 1024

This article mainly introduces PHP using the WebSocket example, the need for friends can refer to the following 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

Once you understand the connection between the network socket and the WEB server, you can send data from the browser to the server and receive the response data returned by the server.The following is an API for creating a new WebSocket object:Copy codeThe Code is as follows: var Socket = new WebSocket (url, [protocal]);Here, the first parameter refers to the URL to be connected, and the second parameter is

This article series shows how to use reverse Ajax (Reverse Ajax) technology to develop event-driven Web applications. The 1th part of the series describes reverse Ajax, polling (polling), streaming (streaming), comet, and long polling (long polling). You've learned how Comet uses HTTP long polling, which is the best way to reliably reverse Aja

This chapter describes how to use the WebSocket API to control protocols and create applications, and using the existing WebSocket servers provided by http://websocket.org, we can send and receive messages, and create some simple websocket applications. Step-by-step learning to use the WebSocket API, and finally we'll

(a) WebSocket profileShort Connection : in the traditional HTTP protocol, the client and server side of the communication mode is a short connection, that is, the server side does not maintain a connection with the client, after the message is sent, will disconnect the connection, the next time the client communication, must be established and the server New connection, This is the short connection. In the case of a short link, the client must activel

WebSocket and websocket 1. What is webSocket? As we all know, the browser supports stateless http. When a user sends a request on the browser side, the server returns a response. This kind of response can be sent only when the user requests continuously. Before html5, to implement a real-time service data retrieval function, you may only need to use the round-rob

As we all know, the HTTP protocol is stateless and interacts with the server based on Request/response, which is what we often call the single-mode. However, with the development of the Internet, the two-way communication between the browser and the server is increasing, and the way of long polling to the servers to get the latest data and push effect is becoming more and more satisfying. HTML5 Standard, also provides us with the browser and the service side of the Duplex Communication protocol

WebSocket and message push, WebSocket message push In B/S-structured software projects, sometimes the client needs to obtain server messages in real time, but the default HTTP protocol only supports the request response mode. This can simplify the Web server and reduce the burden on the server, the response speed is accelerated because the server does not need to establish a communication link with the clie

First knowledge of WebSocket protocol, first knowledge of websocket1. What is the WebSocket protocol?
