Uri.parse（），如何正确编码？

Question

I am doing an application where I have to read a URL from a webpage as a String[Its not the address of the page]. The URL that I will be reading contains query string, and I specifically need two queries from that URL. So I am using the Uri class available in Android. Now, the problem lies in the encoding/format of the URL and the query. One of the queries that I need is always an URL. Sometimes the query URL is %-encoded and sometimes not.

The URLs can be like the following :

Case 1 :

http://www.example.com/example/example.aspx?file=http%3A%2F%2FXX.XXX.XX.XXX%2FExample.file%3Ftoken%3D9dacfc85

Case 2 :

http://www.example.com/example/example.aspx?file=http://XX.XXX.XX.XXX/Example.file?token=9dacfc85

How do I get the correct Url contained in the file= query?

I am using the following [to accomplish the said work universally] :

Uri.decode(urlString.getQueryParameter("file"));

Is this the correct way to do it?

UPDATE

I have decided to first encode the whole URL regardless of its value and then get the query parameter. Theoretically, it should work.

Answer 1

If you are uncertain about the type of URL you would get then I would suggest you to decode every URL you get from the parameter. And when you need to use it then you can encode it.

As per my knowledge, you are doing it right.
