1. 客戶端和服務器聊天，可以一直聊天，直到一方發(fā)送’拜拜’。然后就可以和下一個人一直聊

創(chuàng)建服務器：

import socket

def creat_server():
    """寫一個服務器"""
    server = socket.socket()   # 創(chuàng)建套接字對象
    server.bind(('10.7.153.167', 8000))   # 綁定IP地址和端口
    server.listen(520)        # 開始監(jiān)聽

    while True:
        connect, addr = server.accept()

        while True:
            message = input('服務器：')
            connect.send(message.encode())

            recv_data = connect.recv(1024)

        connect.close()

creat_server()

創(chuàng)建客戶端：

import socket

def creat_client():
    client = socket.socket()

    client.connect(('10.7.153.167', 8000))

    while True:
        data = client.recv(1024)

        message = input('客戶端：')
        client.send(message.encode())

        if message == '拜拜':

            break


    client.close()

creat_client()

import requests

response = requests.post(url)
print(response.content)

data = response.content

with open('./tupian/2.png', 'wb') as f:
    f.write(data)
