如何检测重定向的URL？ [英] How to detect a redirected URL?

问题描述

我正在开发一个应用程序，该应用程序从RSS源获取URL并在视频播放器中打开它们。它是有效的，如果URL直接到mp4 /任何文件，但如果我有一个重定向的URL（例如这一个重定向这里）我的播放器崩溃并失败。

I'm working on an app that takes URLs from RSS feeds and opens them in a video player. It works if the URL is directly to the mp4/whatever file, but if I have a redirected URL (e.g. This one which redirects here) my player crashes and fails.

有没有办法检测它的重定向，以及哪个URL ？

Is there any way to detect if its redirecting, and to which URL?

推荐答案

重定向的网址你可以试试这个

for redirected url you may try this

try {
    HttpResponse response = client.execute(getRequest);
    final int statusCode = response.getStatusLine().getStatusCode();
    if(statusCode == HttpStatus.SC_MOVED_PERMANENTLY || statusCode == HttpStatus.SC_MOVED_TEMPORARILY){
        String location = response.getHeaders("Location")[0].toString();
        String redirecturl = location.replace("Location: ", "");
    }
}
