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

Port multiplexing technology, this can be a good solution to the problem of surprise group and stream_socket_server performance bottlenecks. /*** Multi-process IO multiplexing libevent* Handle multiple connections at the same time* Port Multiplexing---recommended PHP7*/Class Xtgxiso_server{Public $socket = false;Public $master = Array ();public $onConnect = null;public $onMessage = null;public $onClose = n

, and in fact he is different. For synchronous calls, many times the current thread is still active, but logically the current function does not return.Example:1. Synchronous Call: Apply a cumulative 100 million-time task, the call will wait until the task returns the result, but not blocked (that is, the execution of the CPU has been robbed, it is in the ready state);2. Blocking call: When the socket is working in blocking mode, if the recv function

This article mainly introduces node. socket. io broadcast messages. For more information, see socket. the io () server has a sockets attribute. The attribute value is all socket objects connected to the client. you can use the send method or emit method of this object to bro

Socket. IO is a websocket library, including the client js and the server nodejs. Official Address: socket. io uses socket. io and nodejs to build a websocket Server Socket.

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

Session is required for some authentication in the nodejs project. For example, the demo of the nodejs chat room I wrote is the authentication implemented through session. If a session exists, you can directly log on to the chat room without logging on again. I also found many session calling methods in the Express framework on the Internet, but I found that not many of them are actually usable. Today, based on the production process of the chat room, I sorted out Express and

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.

At present, there is a need to connect to the socket. io server of the other party, then receive and store the data. However, no connection code is found for the socket. io client of the php version. Only the connection code of the server is found. Therefore, a client connection code is obtained here. I am grateful for
