Preface Today, users expect fast and dynamic applications that can be accessed through the web. This article series shows how to use reverse Ajax (reverse Ajax) technology to develop event-driven Web applications. Part 1 of the series describes reverse Ajax, polling, streaming, Comet, and long polling ). You have learned how comet uses HTTP long polling. This is the best way to reliably implement reverse Ajax, because all existing browsers provide support. Part 1 of the series illustrates how to

This article mainly introduces node. socket. js. i/O advanced usage skills. This article describes the configuration, room, event, authorization, and other content. For more information, see Socket in the previous blog. IO, I briefly introduced Socket. i/O basic usage and a simple chat room DEMO is created. This articl

Preface Before seeing a very humorous way to explain the windows of the socket IO model, to borrow this story to explain the Linux socket IO model; Lao Chen has a daughter who works in the field and can't often come back, Lao Chen and her through letter contact.Their letters will be delivered by the postman to the ma

Socket. io provides event-based Real-time bidirectional communication. The following article mainly introduces socket. i/O basic application-related materials have some reference and learning value for everyone. Let's take a look at them. Socket. io provides event-based Real

This article mainly introduces the socket. io entry instance in node. js, and introduces reverse ajax technologies such as websocket. For more information, see Introduction to websocket and other Reverse ajax Technologies In real-time web applications, a common method is reverse Ajax. Definition of reverse Ajax: Reverse Ajax (Reverse Ajax) is essentially a concept that can send data from the server to the

Introduction to websocket and other Reverse ajax Technologies In real-time web applications, a common method is reverse Ajax. Definition of reverse Ajax: Reverse Ajax (Reverse Ajax) is essentially a concept that can send data from the server to the client. In a standard HTTP Ajax request, data is sent to the server. Reverse Ajax can simulate an Ajax request in some specific ways, which will be discussed in this article, the server can send events (low-latency communication) to the client as quic

PrefaceHave seen in a very humorous way to explain the Windows Socket IO model, borrow this story, explain the Linux socket IO model;Lao Chen had a daughter who worked outside and could not come back often, and she contacted her by letter.Their letters will be delivered by the postman to the mailroom in front of their

Node. js and Socket. IO extend Django's real-time processing functions This article mainly introduces the use of Node. js and Socket. i/O extends Django's real-time processing function. The real-time asynchronous processing function is quite powerful. The example given in this article is to create a real-time chat room. For more information, see Today, our goal i

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

This article will share with you how to use node. js to implement multi-room chat code based on socket. io + express. It is very practical and can be referenced by partners who need it. Socket. io Introduction Socket. IO is an op

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

Nodejs implements chat rooms based on socket. io Because the socket. io module is used for the web video Live project to be implemented later, I spent some time studying it and made some improvements by referring to the online code. I wrote a chat room code myself. I have to admit that the backend fact push capability

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.

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

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

1. how to prevent socket. i/O request captured 2. why my socket. io requests are two such requests: post, get, dozens of milliseconds, and 3 more than one second. if you have a chat room, you can chat privately and enjoy the reward 4. socket cluster-related and disconnection reconnection mechanisms, read a lot... 1. ho

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

Use socket. io in node. js to create a namespace. If developers want to completely control the sending of messages and events in a specific application, they only need to use a default "/" namespace. however, if developers need to provide applications to other applications as third-party services, they need to define an independent namespace for a socket port use
