#  - 连接服务器
#  -发送数据
#  - 接受数据
#  - 关闭socket

import socket

s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
s.connect(('www.baidu.com',80))

s.send(b'GET/HTTP/1.1/r\nHost:www.baidu.com\r\nCpnnection:close\r\n\r\n')
buf = []

while True:
    d = s.recv(1024)
    if d:
        buf.append(d)
    else:
        break

data = b''.join(buf)
s.close()

header, html = data.split((b'\r\n\r\n'),1)
print(header.decode('UTF-8'))
with open(r'C:\Users\dhf\Desktop\baidu.html','wb') as b:
    b.write(html)
