Use Socket. io to push messages in real time, and socket. io to push messages in real time. Project Background There is a social network module in a recently written project. You need to implement this function: when a user is liked, commented, or followed, the server needs to push a message to the user in real time. The final project address is https://github.com/noiron/

In general, the socket can be divided into TCP sockets and UDP sockets, further, can also be divided into server-side sockets and client sockets. In this section we first focus on the TCP socket server-side Socket,java in the ServerSocket class corresponding to it, this class is mainly used to create a socket service o

HP-socket is a set of universal high-performance Windows Socket component packages, including the server component (iocp model) and the client component (event select model). It is widely used in Windows TCP communication systems. HP-socket fully encapsulates the communication layer, and upper-layer applications do not need to pay attention to any details of the

Client : Create socket (socket) Connecting to a server (connect) Communication (SEND,RECV or Write,read) Close socket (closesocket) Example code:intMainintargcChar*argv[]) { Const intBuf_size = -; Wsadata WSD; //wsadata VariableSOCKET Shost;//Server SocketsSockaddr_in servaddr;//Server Address CharBuf[buf_size];//Receive

Asynchronous client socket example The following example creates a client to connect to the server. The client is generated using an asynchronous socket, so the execution of the client application is not suspended when the server returns a response. The application sends the string to the server and then displays the string returned by the server on the console. C # Using System;Using System. Net;Using Sys
