Demonstrates how to get a Google OAuth2 access token from a desktop application or script.

#  See Global Unlock Sample for sample code.

#  For Google OAuth2, set the listen port equal to the port used
#  in the Authorized Redirect URL for the Client ID.
#  For example, in this case the Authorized Redirect URL would be http://localhost:55568/
#  Your app should choose a port not likely not used by any other application.

#  At this point, your application should load the URL in a browser.
#  For example,
#  in C#:  System.Diagnostics.Process.Start(url);
#  in Java: Desktop.getDesktop().browse(new URI(url));
#  in VBScript: Set wsh=WScript.CreateObject("WScript.Shell")
#               wsh.Run url
#  The Google account owner would interactively accept or deny the authorization request.

#  Add the code to load the url in a web browser here...

#  4: Completed with Access Denied. The OAuth2 flow has completed, the background thread exited, and the error JSON is available in AccessTokenResponse property.
#  5: Failed Prior to Completion. The OAuth2 flow failed to complete, the background thread exited, and the error information is available in the FailureInfo property.
