tornado - 求助：想开发一个1对1类似微信一样聊天的服务，该如何实现？python

Answer 1

After the server socket receives the connection, calling accept will generate a new socket object used to communicate with the client. So the server only needs to keep the two socket objects of you and your friend. For example, s1 and s2. Then when the server receives the message from s1. The server then sends it to your friend through s2.
This is my idea, I haven’t tried it myself. You can refer to it.

Answer 2
