Code example of coroutine implementing TCP connection in python

The content of this article is about the code examples of coroutines in python to implement TCP connections. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

In network communication, each connection must create a new thread (or process) for processing. Otherwise, a single thread cannot accept connections from other clients while processing the connection. So we try to use coroutines to implement the server's response to multiple clients.
The same architecture as the single TCP communication, except that coroutines are used to implement multiple tasks at the same time.

#服务端
import socket
from gevent import monkey
import gevent
monkey.patch_all()
def handle_conn(seObj):
    while True:
        re_Data  = seObj.recv(1024).decode('utf-8')
        if re_Data == 'quit':
            break
        print('client>>',re_Data)
        value  = input("server>>")
        se_Data = seObj.send(value.encode('utf-8'))
        if se_Data == 'quit':
            break
if __name__ == '__main__':
    server = socket.socket()
    server.bind(('192.168.1.227',9876))
    print("服务已开启")
    server.listen(4)
    while True:
        seObj,add = server.accept()
        gevent.spawn(handle_conn,seObj)
    seObj.close()
    server.close()
