实现TCP
# -*- coding: utf-8 -*-
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\nConnection: close\r\n\r\n')
buffer = []
while True:
d = s.recv(1024)
if d:
buffer.append(d)
else:
break
data = b''.join(buffer)
s.close()
header, html = data.split(b'\r\n\r\n', 1)
print(header.decode('utf-8'))
with open('sina.html', 'wb') as f:
f.write(html)
UDP连接服务端：
# -*- coding: utf-8 -*-
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
s.bind(('127.0.0.1', 9999))
print('Bind UDP on 9999...')
while True:
data, addr = s.recvfrom(1024)
print(addr)
reply = data.decode('utf-8')
s.sendto(reply.encode('utf-8'), addr)
客户端：
# -*- coding: utf-8 -*-
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
for data in [b'Michael', b'Tracy', b'Sarah']:
# 发送数据:
s.sendto(data, ('127.0.0.1', 9999))
# 接收数据:
print(s.recv(1024).decode('utf-8'))
s.close()
