您可能要添加 -I (这是一个大写字母) i)，这将使命令不下载任何主体"，但是它随后也使用HEAD方法，这不是所包含的问题，并且可能会更改服务器的功能.有时，即使服务器对GET的响应很好，服务器对HEAD的响应也不会很好.

You might want to add -I (that is an uppercase i) as well, which will make the command not download any "body", but it then also uses the HEAD method, which is not what the question included and risk changing what the server does. Sometimes servers don't respond well to HEAD even when they respond fine to GET.
