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()
