curl 302重定向不工作（命令行） [英] curl 302 redirect not working (command line)

问题描述

在浏览器中，导航到此网址会启动302（暂时移动）请求，该请求依次下载文件。

In the browser, navigating to this URL initiates a 302 (moved temporarily) request which in turn downloads a file.

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，我发现重定向将转到动态生成的路径，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。

When I view what is actually happening via Chrome network tools I see that the redirect is going to a dynamically generated path that cancels itself immediately after download. In other words, even if I know that full path I will not have time to manually call it.

所以，如何使用命令行可以模仿浏览器动作？

So, how in using the command line can I mimic the browser actions?

我试过

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

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

但这只是返回乱码。这样做的目的是以编程方式下载此文件，而无需导航到网站。不幸的是，我不能共享这里的网站，因为它是在登录后面。

but this just returns gibberish. The goal of this is to programmatically download this file without having to navigate to the site. Unfortunately I cannot share the site here as it is behind a log-in.

推荐答案

您需要提供 -L 或 - location 选项，以便启用 curl 跟踪HTTP重定向。

You need to supply the -L or --location option in order to enable curl to follow HTTP redirects.

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.
