Question

我试图从newURLConnection获取重定向的网址，但是当我打印出来时，它仍会在重定向之前输出网址。我确定原始的newURLConnection是合法的URL，因为当我将其输入Web浏览器时，它会自动重定向。我已经尝试将conn.setInstanceFollowRedirects设置为false和true，并且都不起作用......由于某种原因，我无法获得重定向的URL。肯定会得到帮助。

//open a connection
                URLConnection newURLConnection = params[0].openConnection();
                HttpURLConnection conn =  (HttpURLConnection) newURLConnection;
                //following code sourced from mkyong.com
                conn.setInstanceFollowRedirects(true);
                //HttpURLConnection.setFollowRedirects(true);
                conn.connect();
                //get the redirected URL
                InputStream newURLConnectedStream = conn.getInputStream();
                System.out.println("" + conn.getURL());

尝试以下代码来获取它，

URL url = new URL(url);
HttpURLConnection ucon = (HttpURLConnection) url.openConnection();
ucon.setInstanceFollowRedirects(false);
URL secondURL = new URL(ucon.getHeaderField("Location"));
URLConnection conn = secondURL.openConnection();

从java, android, resolve an url, get redirected uri
