使用telnet访问百度

时间:2024-03-03 19:43:18

这里主要是玩一下http协议,查看http的header。

1、输入命令telnet访问百度

# telnet www.baidu.com 80
Trying 220.181.112.244...
Connected to www.baidu.com.
Escape character is \'^]\'.

2、输入请求头,这里有时间限制,很快会自动断开,所以提前写好粘贴进去

GET /index.html HTTP/1.1
Host: www.baidu.com

3、两次回车,返回响应头

HTTP/1.1 200 OK
