Python网络编程Socket之协程

一、服务端

 __author__ = "Jent Zhang"

 import socket
 import gevent
 from gevent import monkey

 monkey.patch_all()          # 把当前程序中的所有IO操作单独做上标记

 def server(port):
     s = socket.socket()
     s.bind(("0.0.0.0", port))
     s.listen()
     while True:
         conn, addr = s.accept()
         gevent.spawn(handle_request, conn)

 def handle_request(conn):
     try:
         while True:
             data = conn.recv()
             print(data.decode("utf8"))
             conn.send(data.upper())
             if not data:
                 conn.shutdowm(socket.SHUT_WR)

     except Exception as ex:
         print(ex)
     finally:
         conn.close()

 if __name__ == "__main__":
     server()

二、客户端

 __author__ = "Jent Zhang"

 import socket

 HOST = "localhost"
 PORT = 

 s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
 s.connect((HOST, PORT))

 while True:
     msg = bytes(input(">>:"), encoding="utf8")
     if not msg: continue
     s.sendall(msg)
     data = s.recv()

     print("Received", repr(data.decode("utf8")))

 s.close()
