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/

Article Source: ASPCN Author: Sun Wen Socket transfer Mode Sockets has two main modes of operation: connection-oriented and connectionless. Connection-oriented sockets operations are like a phone call, They have to establish a connection and a call to one person. All things arrive in the same order as they set out. A connectionless sockets operation is like a mail delivery, and there is no guarantee that multiple messages may arrive in the same orde

The address data structure of the socket has different forms depending on the system and the network environment. In order for the different format addresses to be passed into the socket function, the address structure must be forced to be converted to: struct sockaddr{ sa_family_t sa_family;/* address family*/ char sa_data[];/* Variable-length address*/ ... }; The

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
