Dropbox StaffThanks for the report! Based on your code though, I see that you're running this in a web view, which is not officially supported, per the /oauth2/authorize documentation. (Web views are more prone to issues like this, and are being disallowed by other providers anyway, such as Google, who we support as an sign-in provider for Dropbox.)
That being the case, please switch to using the system browser for the app authorization flow and let me know if you're still seeing any issues there.
Hi Greg,
Ok, but that was how I was taught to do it and is the only way I know. Do you have some sample C#/.NET code for how to do it this other way? I don't see any in the link you gave me, nor any links within that.
thanks,
Donald.

Sure, there's more information and sample code in the documentation for DropboxOAuth2Helper in the .NET SDK.
"A HttpListener is created to listen to the RedirectUri which will later receive redirect callback from the server. Start() is called to launch a native browser and navigate user to the authorize URI".
Hmmm, I remember now trying to do this back in the beginning (because it was in your .NET code) and never succeeded in getting it working. Will have another look at it though. Thanks.
Hey Greg,
Ok, I've gone back and revisited the code I never got working, which was based on SimpleTest. Where I got stuck was stuff around index.html in HandleOAuth2Redirect. At the time you said it wasn't really necessary (just a page that is displayed to the user, which I don't need), and I think I have an idea now how to resolve that, however the way I did get it working in the end, following someone's blog, was using
OAuth2Response result=DropboxOAuth2Helper.ParseTokenFragment(new Uri(e.Url));
in a webview, which is way simpler (much fewer lines of code) than the way it's done in SimpleTest (ParseTokenFragment does all the heavy lifting for you). Would I be able to use that with this different approach? i.e. once I get to http.Start(), what would the next few lines of code look like if I wanted to use ParseTokenFragment instead? (and if this is indeed possible, maybe update SimpleTest to reflect this simpler approach?)
thanks,
Donald.

Using a web view for the app authorization flow is not officially supported, so I can't recommend doing so.
In any case, if you call ParseTokenFragment and it returns successfully, the return value will be a OAuth2Response. You can get the access token from OAuth2Response.AccessToken.
