在浏览器中,导航到此URL会启动302(暂时移动)请求,该请求又会下载文件.
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情况时,我发现重定向将转到动态生成的路径,该路径在下载后立即取消.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,如何使用命令行我可以模仿浏览器操作?
我试过了
curl --cookies bin/cookies.txt -O -L" http://www.targetsite.com/target.php/?event=download&task_id=123 " - 压缩
但这只会带来胡言乱语.这样做的目的是以编程方式下载此文件,而无需导航到该站点.不幸的是,我不能在这里共享网站,因为它是登录后面的.
您需要提供-L
或--location
选项才能启用curl
HTTP重定向.
引用自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.
