OAuthException Facebook and OSQA

Question

I'm using OSQA and I simply trying to login with Facebook (without any change on the platform code), only setting 'app secret' and 'app id'.

My Facebook App settings:

Site URL: http://localhost:8080/osqa/
Canvas URL: http://localhost:8080/osqa/osqa/account/facebook/done/

I encounter this error:

{
   "error": {
      "message": "Invalid redirect_uri: Given URL is not allowed by the Application configuration.",
      "type": "OAuthException",
      "code": 191
   }
}

and this is the url with the redirect_uri

https://graph.facebook.com/oauth/authorize?scope=email&redirect_uri=http%3A%2F%2F127.0.0.1%3A8080%2Fosqa%2Fosqa%2Faccount%2Ffacebook%2Fdone%2F&client_id=***

I read a lot of posts concerning this problem here on stackoverflow and in other forums, I know there is a simple solution, but cannot figure out yet.

The redirect in your URL translates to this:

redirect_uri=http://127.0.0.1:8080/osqa/osqa/account/facebook/done/

Facebook just checks the strings and sees that 127.0.0.1 is not the same as localhost. So replace this in your app settings and the redirect should work.

It gives me back a 404 with this URL "http://127.0.0.1:8080/osqa/osqa/account/facebook/done/?code=***" I delete one occurence of osqa/ and works well. Now I must figure out how to solve the new problem – Massimo Variolo Aug 09 '12 at 21:04
Check your `APP_URL` setting in `settings_local.py`. Pay attention to the comment above: `# This shouldn't be followed by a trailing slash.` – Jan Gerlinger Aug 09 '12 at 21:28
APP_URL = 'http://127.0.0.1:8080/osqa' If I delete "/osqa" I obtain an unuseless URL "http://127.0.0.1:8080/account/facebook/done/?code=***" Maybe is a bug somewhere else? – Massimo Variolo Aug 09 '12 at 21:35
On urls.py I have: "url(r'^%s(?P\w+)/%s$' % (_('account/'), _('done/')), app.auth.process_provider_signin, name='auth_provider_done')," – Massimo Variolo Aug 09 '12 at 21:37
So if you delete `/osqa` one time from the `APP_URL` setting, it is removed twice from the `redirect_uri`? Try changing `_('done/')` to `_('done')`. – Jan Gerlinger Aug 09 '12 at 21:39
Yes. I've tried: "127.0.0.1:8080/osqa/osqa/account/facebook/done?code=***" instead of "127.0.0.1:8080/osqa/osqa/account/facebook/done/?code=***" – Massimo Variolo Aug 09 '12 at 21:45
In the method `process_provider_signin(request, provider)` from `url(r'^%s(?P\w+)/%s$' % (_('account/'), _('done/')), app.auth.process_provider_signin, name='auth_provider_done'),` inside it there is `assoc_key = provider_class.process_authentication_request(request)`. The method `process_authentication_request(self, request):` has this line `args = dict(client_id=settings.FB_API_KEY, redirect_uri="%s%s" % (django_settings.APP_URL, request.path))` Maybe this last line is the problem. – Massimo Variolo Aug 09 '12 at 21:54

Yeah, this is probably a bug there. You could try fix it, or as a dirty workaround hardcode your `redirect_uri` there ;) As you're `APP_URL` contains only one `/osqa` there is probably a `/osqa` to much in `request.path`. – Jan Gerlinger Aug 09 '12 at 21:55

Here is the solution for the second problem ;) http://meta.osqa.net/questions/11746/facebook-login-bug-in-subfolder-install-subfolder-part-of-url-appears-twice-during-login-redirect – Massimo Variolo Aug 09 '12 at 22:48
