websocket tutorial

I. AgreementWebSocket is a protocol of Full-duplex communication between client and server based on TCP, which is defined in HTML5 and is also one of the basic specifications of the next generation WebApp. It broke through the previous limitations of Ajax, the key is real-time, the server can actively push content to the client! Possible applications are: Multiplayer online games, instant chat, real-time monitoring, Remote Desktop, news server and so on. For myself, the most I want to try now

In the project, you need to view the running log of the frame in the Docker container in real time in the browser, and on the server you can get tail-f execution result InputStream stream by the RESTful interface provided by Docker. The browser HTTP protocol is a request-response protocol, in order to obtain data, you must initiate a request, obviously and the Java InputStream concept is not collaborative, the server can not real-time push log stream to the browser. Using AJAX techniques, you ca

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

1. IntroductionTo allow Web apps to maintain two-way communication with server processes, the WebSocket interface is described here . 2. Conformance requirements (abbreviated)3. Terminology (abbreviated)4.WebSocket Interface(Code slightly)The WebSocket (URL, protocols) constructor can pass in a 1-2 parameter. The first host specifies the URL to connect to . The

How does QML interact with C ++ through WebSocket ?, QmlwebsocketPreface As a full-duplex network communication protocol, WebSocket is gradually accepted by various development frameworks and languages. Among them, a large amount of data is transferred between the browser and the program, that is, WebSocket. Today, let's talk about how QML interacts with C ++ thr

Project descriptionWebsocket-client module is websocket client for Python. This provide the low level APIs for WebSocket. All APIs is the synchronous functions.Websocket-client supports only hybi-13.License Lgpl InstallationThis module was tested on Python 2.7 and Python 3.4+.Type "python setup.py Install" or "Pip install websocket-client

Here I draw a diagram demonstrating the handshake part of a websocket connection between the client and the server, which can be done very easily in node, because the net module provided by node has encapsulated the socket socket, and the developer will use only Consider the interaction of the data without dealing with the establishment of the connection. and PHP does not, from the socket connection, establishment, binding, monitoring, etc., these nee

polling, the advantage of background polling is that the foreground does not have to send the request to the background, but wait until the background to find the data updated to remind the foreground to re-request data. This will require the use of websocket.The HTTP connection we normally use is the only client that can send requests to the server.The most important feature of WebSocket is that the server can actively push information to the client

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

Specific WebSocket introduction Visible Http://zh.wikipedia.org/wiki/WebSocket Here, we describe how to use Python to communicate with the front-end JS. WebSocket after the handshake is completed using the HTTP protocol, WebSocket communication is not made directly through HTTP. So, use

Recently, a web game was created as needed. In a certain period of time, the page needs to be refreshed in real time. Currently, the general idea of website creation is to use js polling. Because it is an innovative small project, friends in the same group proposed the WebSocket mentioned in html5. they first conducted technical research. Currently, java does not support many websockets. Few websocket imple

Before the company's real-time chat with the regular round, has always felt very unscientific, the recent backstage said configuration good socket server, I am happy to prepare with asyncsocket, but told me to use WebSocket, based on HTML5, A new bidirectional communication protocol (--websocket) is proposed in HTML5, this paper attempts to use this technology to realize the above real-time chat function.Af

The case is developed and run in the apache-tomcat-8.0.15 and jdk1.8.0_25 environments. However, the title is Java7, it does not affect, the code does not involve any jdk1.8.x-related code. In addition, the reason to clear the software version, one is to ensure that the case can have a clear implementation of the background, the second is websocket to achieve tomcat7.x and tomcat8.x there is a great difference.The Java API for
