This article mainly introduces the example of using websocket in php. If you need a websocket connection, you can refer to the figure below to demonstrate the handshake between the client and the server, this part can be easily completed in node, because the net module provided by node has encapsulated socket, developers only need to consider data interaction instead of connection creation. Php does not, fr
HTTP/WebSocket and httpwebsocketHttp Definition
HTTP is a standard TCP protocol for client and server requests and responses.HTTP request format
The HTTP request format consists of the request line, request header, empty line, and message body. Each part occupies one line.
Request Line: The request line is the first line of the request message. It consists of three parts: the request method (GET/POST/DELETE/PUT/HEAD) the URI path of the requested res
Review the previous chapterIn the previous chapter, "Why do we need HTML5 WebSocket", I briefly introduced the next WebSocket of the past life. I believe that we have a preliminary understanding of the websocket. So today we continue to study the mechanism of websocket in depth.WebSocket mechanismWe know that
Previously mentioned that LUA and NODEJS use socket communication, but because of the service-side constraints, eventually still chose the luasocket.Now, in the face of a new project, I naturally chose WebSocket.Therefore, I need to understand the following questions:
What are the differences and connections between sockets and WebSocket?
What's the relationship between WebSocket and HTML5?
high degree of freedom of customization, data privacy and other aspects of consideration, the final server-client end is self-implementation, the server uses the worker man's PHP socket architecture.On long-connected bidirectional communication, the WebSocket protocol is selected. Development is mainly responsible for the development of iOS client side, in accordance with the development of the third-party SDK standard, the key parts are encapsulated
1. Introduction HTML5 brings the ability of a full-duplex TCP connection WebSocket a standard server to a Web browser.In other words, the browser is able to establish a connection with the server, sending and receiving data through the established communication channels without the need for additional overhead to be introduced by the HTTP protocol.WebSocket offers a popular technology to replace the AJAX technology we've been using for the past few ye
This article mainly introduces WebSocket in HTML5. This article explains what WebSocketAPI is in HTML5, how to use WebSocketAPI in HTML5, and how to use WebSocketAPI with Socket. IO WebSocket, NodeJS, and Socket. i/O joint development and other content. For more information, see
Understand HTML5 WebSocket
In HTML5 specifications, my favorite Web technology is th
Websocket is an important feature of HTML5 and provides two-way communication between the client and server. It is the first choice for many webapps for network communication, but it is not supported in Android WebKit, the socket. i/O popularity. Of course, this feature cannot be missed in our cloud OS. My task this week is to support websocket in the cloud OS WebKit so that webapps can directly call the
In this article we first understand the basic knowledge, so that we can learn more useful behind.Socket,websocket,http,tcp and so on we have heard the ear has a cocoon, but the use of time to review it.University Learning Network Foundation when the teacher said, the network from the bottom up into the physical layer, Data link layer, network layer, transport layer, Session layer, presentation layer and application layer. Through the preliminary under
Most sites use HTTP protocol communication. HTTP is a non-connected protocol. The server-side talent sends a corresponding response only when the client is requested. the HTTP Request package is also larger, assuming only very small data traffic. Too much overhead. As a result, we are able to use the websocket Protocol to implement connection-oriented communication with minimal overhead. Detailed websocket
Recall the previous chapterIn the previous chapter, "Why do we need HTML5 WebSocket", I briefly introduced the next WebSocket of the past life. I believe that we have a preliminary understanding of the websocket. So today we continue to study the mechanism of websocket in depth.WebSocket mechanismWe know that
Http://www.jb51.net/article/112183.htmRecently encountered a demand in the work, need to use Nginx reverse proxy websocket, after looking for some information, has been tested, so this article mainly introduces the Nginx reverse proxy websocket configuration related information, the need for friends can reference, Let's take a look below.Implementation scenariosUsing the more mature
1. Prefacehas not been how to do the front-end things, but the recent project, the front-end personnel scarce, the company does not arrange for new personnel to enter, so I this background developer can only pull over to sit front end, the front section of things feel a lot, css,js from needless to say, the HTML ecosystem has a lot of technology to learn, okay, Then one of the learning to organize, first of all, the recent project of the front end of the use of what technology it.1, Restful:drop
a · What is WebSocketThe WebSocket protocol can communicate more than once after a successful handshake from the HTTP protocol until the connection is closed. However, the handshake in WebSocket is compatible with the handshake in HTTP, which uses the Upgrade protocol header in HTTP to upgrade the connection from HTTP to WebSocket. This makes it easier for the
WebSocket protocol is a new network protocol based on TCP, which realizes the bidirectional traffic between client and server, and allows the service side to send information to the client actively. WebSocket is an agreement in the HTML5.HTTP protocol with WebSocket protocol:The HTTP protocol has only 1.0 and 1.1 two versions,The HTTP protocol is a stateless resp
Working with WebSocket technology, the use of the process found that the browser (Chrome) after the upgrade may cause the WebSocket is not available, the browser can be changed after the normal use.Once in a while, it is occasionally possible to debug locally, discovering that using the same version of the Chrome browser does not connect to the WS service on the online server, but can connect to the local W
Getting started with WebSocket
WebSocket is a network technology that HTML5 provides for full-duplex communication between browsers and services, and the WebSocket Communication protocol was established as the standard Rfc6455,websocket API by the IETF in 2011.In the WebSocket
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. and PHP does not, from the socket connection, establishment, binding, monitoring, and
First, WebSocket Overview
The WebSocket protocol is based on the TCP protocol, not the HTTP protocol.As follows:ws://127.0.0.1 or wss://127.0.0.1 is the websocket request.Note: ws represents WebSocket protocol, WSS represents an encrypted WebSocket agreement. The
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
