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

hello 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

%s' % data).encode('utf8'))
    conn.close()
