Recent projects in the use of Nginx Push_stream_module push module to implement server-to-client information push, originally only want to achieve this one-way communication needs, but to the client push the message, if you want to let the client give a feedback, There's no way to listen to the feedback event that gets to the client and respond in a timely manner. Later know that Push_stream_module management long connection is based on Pub/sub mode, and as if the module does not give a similar

of data to pay a huge price, it is very uneconomical, occupy a lot of broadband.Disadvantage: can cause excessive unnecessary requests, waste traffic and server resources, every request, reply, wasted a certain amount of traffic on the same header informationHowever, the appearance of websocket can compensate for this shortcoming. In WebSocket, only the server and browser are required to perform a handshak

[This article is original, if reproduced, please indicate the source http://blog.csdn.net/yl02520/article/] Browser has supported the HTTP protocol, so why develop a new websocket protocol? We know that the HTTP protocol is a one-way network protocol, after the connection is established, it only allows Browser/ua (useragent) to send webserver request resources, webserver can return the appropriate data. And webserver can not take the initiative to pus

Introduction and principle of websocket 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. --Baidu Encyclopedia Purpose: Instant messaging instead of pollingThe Instant Messenger on the website is very common, such as the QQ of the webpage, chat system and so on.

Websocket server handshake protocol test webpage code, websocket handshake The test webpage code is as follows:

. ':' . $ERRSTR); $wsData = Fread ($this->_socket, 2000); $retData = Trim ($wsData, Chr (0). chr (255)); return $retData; } Private Function Encode ($data) {$data = Is_array ($data) | | is_object ($DATA)? Json_encode ($data): (String ) $data; $len = strlen ($data); $mask = Array (); for ($j = 0; $j Can send an array to the server, how to receive data? Http://www.workerman.net/workerman-chatCan look at this, php written

The > ' WebSocket ' protocol enables full-duplex communication at the front and back end, replacing long-polling for wasted resources. On the basis of this protocol, the front-end data, the multi-data, real * * Real-time response can be realized. In the course of learning ' WebSocket ', a simplified version of Group chat was implemented, with detailed documentation of the process and code in this article. *

onclick event. What we're going to do is probably the following steps: 1. Get input2. The data needed to assemble a string3. Send to the background the first step is simple, using jquery for a second, the second step can be done using the Json.stringify () method, The third step is to use the Stompclient send method, the Send method has three parameters, the first is to send the address, the second parameter is the header information, the third param

refers to a specific time interval (such as every second), the browser to the server to initiate an HTTP request, and then the server returned data to the browser.Because the HTTP protocol is inert, the server will return data only if the client initiates the request. The precondition for the implementation of polling technology is also based on this mechanism. While WebSocket belongs to the service-side push technology, the essence is an application

In B/S model Web applications, the client often needs to maintain continuous updates with the server. Such applications that require high timeliness include stock price queries, real-time commodity prices, automatically updated Twitter timeline, and browser-based chat systems (such as Gtalk. Due to the rise of Ajax technology in recent years, there have also been many implementation methods. This article will describe these methods and demonstrate them with
