仅使用curl从HTTP POST获取响应标头 [英] Getting only response header from HTTP POST using curl

问题描述

您可以使用HTTP HEAD仅请求标头，如 curl（1）中的选项 -I / p>

One can request only the headers using HTTP HEAD, as option -I in curl(1).

$ curl -I /

长时间的HTML响应体是一个痛苦的命令行，所以我想只获得标题作为我的POST请求的反馈。但是，HEAD和POST是两种不同的方法。

Lengthy HTML response bodies are a pain to get in command-line, so I'd like to get only the header as feedback for my POST requests. However, HEAD and POST are two different methods.

如何让curl只显示POST请求的响应头？

How do I get curl to display only response headers to a POST request?

推荐答案

-D, --dump-header <file>
          Write the protocol headers to the specified file.

          This  option  is handy to use when you want to store the headers
          that a HTTP site sends to you. Cookies from  the  headers  could
          then  be  read  in  a  second  curl  invocation by using the -b,
          --cookie option! The -c, --cookie-jar option is however a better
          way to store cookies.

。因此

curl -s -D - www.acooke.org -o /dev/null

将标头转储到stdout，并将数据发送到/ dev / null（这是一个GET，而不是POST，但你可以做有POST的东西 - 只需添加您已经用于POSTing数据的任何选项）

dumps the headers to stdout and sends the data to /dev/null (that's a GET, not a POST, but you can do the same thing with a POST - just add whatever option you're already using for POSTing data)

请注意 - -D ，表示输出file是stdout。

note the - after the -D which indicates that the output "file" is stdout.
