套接字通信底层原理

套接字通信底层原理
由应用程序内存拷贝到操作系统，操作系统遵循TCP协议向对方去发，对方接收到并发送信号

from socket import *

client = socket(AF_INET, SOCK_STREAM)
client.connect(('127.0.0.1', 8081))

# 通信循环
while True:
    msg=input('>>: ').strip() #msg=''
    if len(msg) == 0:continue
    client.send(msg.encode('utf-8')) #client.send(b'')
    print('has send')
    data=client.recv(1024)
    print('has recv')
    print(data)

client.close()
