事例2：

服务端：

import socket
ip_port=("127.0.0.1",9999)
sk=socket.socket()
sk.bind(ip_port)
sk.listen(5)
while True:

    print("server waiting")

        except Exception:
            print("client close.")
            break

客户端：

import socket
ip_port=("127.0.0.1",9999)
sk=socket.socket()
sk.connect(ip_port)

sk.sendall(bytes("请求占领地球",encoding="utf-8"))

print(str(server_reply,encoding="utf-8"))
while True:
    enter=input("enter:")
    sk.send(bytes(enter,encoding="utf-8"))
sk.close()

在Linux服务端：

import socket
ip_port=("127.0.0.1",9999)
sk=socket.socket()
sk.bind(ip_port)
sk.listen(5)
while True:

    print("server waiting")
    conn,addr=sk.accept()
    client_data=conn.recv(1024)
    print(str(client_data,encoding="utf-8"))
    conn.sendall(bytes("不要回答,我不想被占领",encoding="utf-8"))
    while True:

        client_data=conn.recv(1024)
        print(str(client_data,encoding="utf-8"))

        if not client_data:
            break
        conn.send(client_data)
    conn.close()
