Download files from Google drive

https://developers.google.com/drive/web/manage-downloads

In the above link it is given that we have to make a GET request to the downloadUrl (which we get in the response when we upload the file) in order to get the file contents.

The downloadUrl which I got after uploading file to google drive is :
"downloadUrl": "https://doc-10-cc-docs.googleusercontent.com/docs/securesc/2butu3k0aok5svkleqovepe3uqqvauqr/9o0jdpikd3jl5krf0vgcacuhfl8gro0v/1408694400000/05688347114777583261/05688347114777583261/0B602YDdndVQ6LUxZRC0wX1ZtWWs?h=16653014193614665626&e=download&gd=true"

Now i am making GET request like this:

        Http http = new Http();
        HttpRequest req = new HttpRequest();
        req.setMethod('GET');
        req.setEndpoint(downloadURL);
        req.setHeader('content-type', 'text/plain');
        req.setHeader('Authorization','Bearer '+accessToken);
        req.setTimeout(60*1000);
        HttpResponse resp = http.send(req);

My problem is that, each time i upload the file i will get different downloadUrl such that it is difficult to change the remote site settings every time.
Any way to dynamically change the remote site setting? Please help me.

I got the solution to the above question. To get the contents of the uploaded file we can set end point like this:

req.setEndpoint('https://googledrive.com/host/'+''+ID);

instead of req.setEndpoint(downloadURL);

where ID is the file id which we get in the response.
