图片中的http响应报文有什么问题?

What's wrong with the http response message in the pictures?

我的老师告诉我response message里有one error,但我认为没有错误。

请帮帮我, 谢谢。

这是回复信息:

HTTP/1.1 301 Moved Permanently\r\n
Server: nginx \r\n
Content-Type: test/html\r\n
Date: Thu, 18 Oct 2018 08:08:24 GMT\r\n
Location: https://www.bbc.co.uk/\r\n
Content-Length: 17\r\n
Connection: Keep-Alive\r\n
\r\n
<html><head><title>301Moved Permanently</title></head>\r\n
<body bgcolor="white"><h1>301 Moved Permanently</h1></body></html>\r\n

The picture of the response message

Content-Length: 17\r\n

内容超过17个字节:

<html><head><title>301Moved Permanently</title></head>\r\n
<body bgcolor="white"><h1>301 Moved Permanently</h1></body></html>\r\n
