curl 302 重定向不起作用(命令行)

Question

在浏览器中，导航到此 URL 会启动 302（临时移动）请求，进而下载文件。

http://www.targetsite.com/target.php/?event=download&task_id=123

当我通过Chrome网络工具查看实际发生的事情时，我看到重定向将转到动态生成的路径，该路径在下载后立即自行取消。换句话说，即使我知道完整路径，我也没有时间手动调用它。

那么，如何使用命令行来模仿浏览器操作呢？

我试过了

curl --cookies

bin/cookies.txt -O -L "http://www.targetsite.com/target.php/?event=download&task_id=123" --压缩

但这只会返回胡言乱语。这样做的目的是以编程方式下载此文件，而无需导航到站点。不幸的是，我无法在此处共享该网站，因为它位于登录状态后面。

您需要

提供-L或--location选项，以使curl能够遵循HTTP重定向。

引用man curl：

   -L, --location
          (HTTP/HTTPS)  If  the server reports that the requested page has
          moved to a different location (indicated with a Location: header
          and  a  3XX  response code), this option will make curl redo the
          request on the new place. If used together with -i, --include or
          -I, --head, headers from all requested pages will be shown. When
          authentication is used, curl only sends its credentials  to  the
          initial  host.  If a redirect takes curl to a different host, it
          won't be able to intercept the user+password. See  also  --loca‐
          tion-trusted  on how to change this. You can limit the amount of
          redirects to follow by using the --max-redirs option.
          When curl follows a redirect and the request is not a plain  GET
          (for example POST or PUT), it will do the following request with
          a GET if the HTTP response was 301, 302, or 303. If the response
          code  was  any  other  3xx code, curl will re-send the following
          request using the same unmodified method.
