01- web应用与https协议
1、
import socket server = socket.socket() server.bind(("127.0.0.1", 8800)) server.listen(5) while True: print('server is waiting...') conn, addr = server.accept() data = conn.recv(1024) print('data:', data) # conn.send(b'hello luffycity') conn.send(b'HTTP/1.1 200 OK\r\n\r\nhello luffycity') # 添加http响应头 conn.close()

import socket server = socket.socket() server.bind(("127.0.0.1", 8800)) server.listen(5) while True: print('server is waiting...') conn, addr = server.accept() data = conn.recv(1024) print('data:', data) # 读取html文件 with open('index.html', 'r') as f: data = f.read() # 响应报头 + data conn.send(('HTTP/1.1 200 OK\r\n\r\n%s' % data).encode('utf8')) conn.close()
3.http请求协议
请求格式
get方式
