The following figure shows the handshake between the client and the server when a websocket connection is established. This part can be easily completed in node, because the net module provided by node has encapsulated socket sockets, developers only need to consider data interaction instead of connection creation. Php does not, from socket connection, establishment, binding, listening, etc., all of which need to be operated by ourselves, so it is nec

high-performance and highly available, the WebSocket protocol requires a load-balancing layer, Nginx supports WebSocket starting from 1.3, which can be used as a reverse proxy and load balancing for websocket programs. Nginx Configuration Note: See official documents said Nginx after 1.3 version of the support WebSocket

We can also have a special broker, and WebSocket is the connection between the node and the broker, which is the WebSocket application messaging Protocol, but the small example does not use the specialized broker method. clusterevent A small example passes the event object directly in the
The example in this paper describes PHP based on WebSocket to build a simple chat room practice. Share to everyone for your reference. Specific as follows: 1. Preface Company game inside there is a simple chat room, understand the later only know is Node+websocket do, think of PHP also to do a simple chat room. So gather all kinds of information to look at the
Reprinted by the author: By: 88250 Time: January 1, January 1, 2010 We use a simple example to familiarize ourselves with HTML 5 websocket. In this example, the server increments an integer every second from 0 and sends it to the client browser for display. Preparation: Download jetty 7, Java Web development environmen

WebSocket IntroductionWebSocket is an important feature of HTML5. It is HTML5 a new protocol that implements browser-to-server full-duplex communication (Full-duplex). Enables the server to proactively transmit data to the client, useful for building a real-time Web application WebSocket principle WebSocket Background and advantages: Http://zh.wikipedia.org/wiki/

When WebSocket is communicating, it is possible to choose a transmission mode with string or byte stream. However, when sending and receiving, it is necessary to consider the subcontracting of the data, which is divided into request and response messages. No matter which mode of transmission is used, it is unavoidable to encounter this problem.When a string is transferred, the receiving side can stitch together each received string, and then detect wh
