Could you please tell me why a GET request to a last.fm web service
URL returns a different result whether I call it from a browser or
from a QNetworkAccessManager?
A specific example would be the following URL:
http://ws.audioscrobbler.com/2.0/?album=American+IV%3A+The+Man+Comes+Around&format=json&autocorrect=1&artist=Johnny+Cash&mbid=261de123-7315-4a2f-8c40-3dad9092313e&api_key=295a01cfa65f9e521bdd2cc3c36d7c89&method=album.getinfo
Pasting it into Google Chrome's address bar produces the expected
album info page.
However, calling the same URL with a QNetworkRequest to a
QNetworkAccessManager returns a response with the following body:
{"error":6,"message":"Album not found"}
Attached is a short program demonstrating this.
Obviously, the program is not making the call correctly. How should I
correct it?
