python之socket运用2

今天实现在客户端和服务端之间进行持续的通信

客户端代码

import socket
ip_port = ("127.0.0.1",3000)
sk = socket.socket()
sk.connect(ip_port)
sk.sendall(bytes("请求占领地球",encoding="utf-8"))
server_replay = sk.recv(1024)
print(str(server_replay,encoding="utf-8"))
while True:
    client_input = input(">>client:").strip()
    sk.sendall(bytes(client_input,encoding="utf-8"))
    server_replay = sk.recv(1024)
    print(">>server:",str(server_replay,encoding="utf-8"))
sk.close()

服务端代码

import socket
ip_bind = ("127.0.0.1",3000)
sk = socket.socket()
sk.bind(ip_bind)
sk.listen(5)
while True:
    print("server is waiting.....")
    conn,add = sk.accept()
    client_data = conn.recv(1024)
    print(str(client_data,encoding="utf-8"))
    conn.sendall(bytes("不要不要回答，不要回答，不要回答",encoding="utf-8"))
    while True:
        try:
            client_data = conn.recv(1024)
            print(">>client:",str(client_data,encoding="utf-8"))
        except Exception:
            print("connection is failed")
            break
        server_reply = input("server>>:").strip()
        conn.sendall(bytes(server_reply,encoding="utf-8"))
    conn.close()
