python3 TCP协议下的socket

--------------------------------------tcp_server.py--------------------------------------

# coding:utf-8
import socket

server = socket.socket()  # 创建socket对象
ip_port = ("127.0.0.1", 8001)  # ip地址和端口号
server.bind(ip_port)  # 绑定ip地址和端口号
server.listen(2)  # 监听ip地址和端口号
conn, addr = server.accept()  # 创建连接通道,接收客户端的连接, conn为客户端和服务端的通道,addr为客户端的IP和端口号
print("conn:", conn)
print("addr:", addr)
from_client_msg = conn.recv(1024)  # 通过通道接收来自客户端的消息,最大为1024B,消息为bytes类型
from_client_msg = from_client_msg.decode("utf-8")
print("来自客户端的消息:", from_client_msg)
server_input = input(">>>: ").strip()
conn.send(server_input.encode("utf-8"))  # 通过通道发送消息,消息类型为bytes
conn.close()  # 关闭通道
server.close()  # 关闭socket连接


--------------------------------------tcp_client.py--------------------------------------

# coding:utf-8
import socket

client = socket.socket()  # 创建socket对象
ip_port = ("127.0.0.1", 8001)  # 服务端IP和端口号
client.connect(ip_port)  # 根据IP和端口号连接服务端
client_input = input(">>>: ").strip()
client.send(client_input.encode("utf-8"))  # 发送消息给服务端
from_server_msg = client.recv(1024)  # 接收来自服务端的消息,最大为1024B,数据类型为bytes
print("来自服务端的消息: ", from_server_msg.decode("utf-8"))
client.close()  # 关闭连接
