推荐答案

您可以使用Android中的Uri类来执行此操作; https://developer.android.com/reference/android/net/Uri.html

You can use the Uri class in Android to do this; https://developer.android.com/reference/android/net/Uri.html

Uri uri = Uri.parse("http://www.chalklit.in/post.html?chapter=V-Maths-Addition%20&%20Subtraction&post=394");
String server = uri.getAuthority();
String path = uri.getPath();
String protocol = uri.getScheme();
Set<String> args = uri.getQueryParameterNames();

然后您甚至可以从查询参数中获取特定元素;

Then you can even get a specific element from the query parameters as such;

String chapter = uri.getQueryParameter("chapter");  //will return "V-Maths-Addition "
