4. Design principle
1. Server side: Accept the connection module, accept the information module
When starting a server-side program, start a thread to listen for the connection signal, if once received the connection signal immediately start receiving the message of the thread, at this time, there are 2 threads running, listening to the connection signal based on the client information to determine whether to start or abort the thread receiving the information.
2. Client: Send the connection request module, send the information module
