Http 请求头部详解

 

 

 

 

 

 

 

 

我们用个python演示包体 看下加粗部分响应长度给了指定长度10 实际是11的长度

import socket

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
serverAddress = ("127.0.0.1", 12345)
sock.bind(serverAddress)
sock.listen(100)

while True:
    conn, client_add = sock.accept()
    try:
        data = conn.recv(4096)
        response = "HTTP/1.1 200 OK\r\nContent-Length: 10\r\n\r\nhello world"
        conn.send(response.encode())
    finally:
        conn.close()

通过转包发现长度也是10也就表示content-length头部是非常重要的参数
