This article mainly introduces the use of Node. js and Socket. i/O extends Django's real-time processing function. asynchronous real-time processing is quite powerful. the example in this article is to create a real-time chat room. if you need it, refer to the following example, our goal is to use Django, Redis, and Socket. IO creates a real-time chat room. Altho
This article mainly introduces node. use socket in js. io method. For more information, see use socket. use io to create a socket. i/O server. however, this server depends on a created http server.
After the http server is running, use the listen method to append a
I. Source Code Installation
To use socket, you can only download the latest version from the official website and install it from the source code. (The package name under Ubuntu is recorded here, which is difficult to find)
1: Install libpcre3-dev,
2: OpenSSL library is not used. I have installed OpenSSL libssl-Dev. Later we found that we wanted to specify the source code path of OpenSSL.
./Configure -- prefix =/usr/local/nginx -- With-OpenSSL
Let me explain why I wrote this first.
When the program is too hard, really, for a long time, really do not have a sense of accomplishment to move bricks, good people can build a building (body can also be good ), we don't know which day a bear child will get rid of the hard drive.
This semester, I have never been at the forefront ...... Khan, I still want to eat some food in the future, but I have never had a rest this semester, but I am busy with a lot of things that many people may thin
This article to share the content is about PHP implementation of System programming network socket and IO multiplexing, has a certain reference value, the need for friends can refer to
All along, PHP is rarely used for socket programming, after all, is a scripting language, efficiency will become a big bottleneck, but can not say that PHP can not be used for
Use node. js + socket. io + redis to implement basic chat room scenarios
This article introduces the basic operations of Redis and Redis-cli in the redis database and its basic operations. among them, the publish-subscribe mechanism is widely used, so we will use nodejs to implement this mechanism. this article describes how to use socket in the previous article.
As mentioned earlier, websocket has some client frameworks to simplify programming. Today, we use socket. Io and node. js to write a helloworld websocket communication.One of them is socket. io, socket. io belongs to node. JS (nod

I recently reviewed socket programming, which is used to help myself and everyone remember.
The socket Io model can manage the communication on the socket. The details are as follows:
1. Select model:By placing the socket into the set and filtering by the Select function
Recently, a young man complained that Ajax was weak and could not achieve persistent connections. Then he kept crying .... in fact, this may not be implemented. For long links, comet and server push rely on the server. If the server implements server push, it is easy to say that, I understand that most servers currently support Apache, Jetty, fast CGI, and ninix (re-add nginx_http_push_module to compile), but this is often not enough... well, this is not good. I have translated a

Keywords: NIO, Io,bio,aio and evolution reasons
I do not really understand NIO, this article is only a brief introduction of the code under the https://github.com/zhaikaishun/NettyTutorial socket01 Traditional bio communication: Synchronous blocking mode
Look at the picture, invade and delete
The traditional model is the Bio mode, which is synchronized blocking, just look at the example below.Server Side

This article mainly introduces socket in node. io event Usage Details. For more information, see socket. the io class library can not only send messages to each other, but also send events to each other through the emit method of the socket port object.
In the previous even
The socket. io client is very elegant in event processing, which is similar to weboscket's limited javascript interface, but supports more custom events:
Var socket = io. connect ('HTTP: // localhost: 9000/chat ');
Socket. on ('connect ', function (){// Your code here});

Socket. io, user node. as a server, js is used for Synchronous synchronization. For example, when a user logs on to a website, multiple windows of the browser are displayed after logon.
First, install socket. io and the required modules, reference the js package of socket.
