Python 协程 socket

服务器端：

import socket
import gevent
from gevent import monkey

monkey.patch_all()

def handle_request(conn):
    print("in the handle")
    try :
        while True:
            data=conn.recv(1024)
            print("recv:",data)
            conn.send(data)
            if not data:
                conn.shutdown(socket.SHUT_WR)
    except Exception as ex:
        print(ex)
    finally:
        conn.close()
def server(port):
    s=socket.socket()
    s.bind(("localhost",port))
    s.listen(500)
    while True:
        cli,addr=s.accept()
        gevent.spawn(handle_request,cli)
if __name__ == "__main__":
    server(9999)

客户端：

import socket
PORT = 9999
HOST = "localhost"

s = socket.socket()
s.connect((HOST,PORT))
while True:
    data=input(">>:")
    msg = bytes(data.encode("utf-8"))
    s.send(msg)
    data=s.recv(1024)
    print("recieved",data.decode())
s.close()
