Python学习之路（6）：socket

Socket

socket通常也称作“套接字”，用于描述IP和端口，是一个通信链的句柄，应用程序通常通过“套接字”向网络发出请求或者应答网络请求。

import socket

ip_port = ("127.0.0.1",8008)
back_log = 5
buffer_size = 1024
tcp_server = socket.socket(AF_INET,SOCK_STREAM)
tcp_server.bind(ip_port)
tcp_server.listen(back_log)
conn,addr = tcp_server.accept()
data = conn.recv(buffer_size)
print("The message received from the client is: ",data.decode("utf-8"))
conn.sendall(data)
conn.close()
tcp_server.close

import socket

ip_port = ("127.0.0.1",8008)
buffer_size = 1024

tcp_client = socket.socket(AF_INET,SOCK_STREAM)
tcp_client.connect(ip_port)
tcp_client.sendall("hello world".encode("utf-8"))
msg = tcp_client.recv(buffer_size)
print("The massege received from the server is:",msg.decode("utf-8"))
tcp_client.close()
