How do I retrieve the data for this plugin?

I installed the Google Opauth Strategy and it's working brilliantly. The LinkedIn one acts a little differently; in the directions for this strategy it specifies that no OAuth Redirect URL is needed (on the LinkedIn Developer website). I tried leaving this out, and kept getting this error:

'Invalid redirect_uri. This value must match a URL registered with the API Key.'

This error is also on the demo for the plugin here: http://opauth.org/#demo

So I changed it up a bit and placed my redirect URL there just in case, like my Google one has, and it seemed to have worked! It took me to the LinkedIn login screen, I put in my credentials, and it redirected me back to my application. The trouble is, no data was returned this time.

My defaults in LinkedInStrategy.php looks like this:

public $defaults = array(
'redirect_uri' => 'http://localhost/users/login',
'response_type' => 'code',
'scope' => 'r_fullprofile r_emailaddress r_contactinfo'
);

In my controller I have this:

$_SESSION['log'] = $this->data;

In my view I have this:

debug($_SESSION['log']);

This is just to see if the data is setting. When I log in with GoogleStrategy.php settings, it returns all of the data and I use it to log me in. Perfect. But with this one, I just get empty arrays. Has something changed?

I solved it! I changed the redirect_uri back to default:

'redirect_uri' => '{complete_url_to_strategy}oauth2callback',

In the LinkedIn Developer API area, I placed this URL in the OAuth 2.0 Redirect URLs:

http://example.com/auth/linkedin/oauth2callback

So the OAuth Redirect URL DOES need to be set, unlike what's stated in the instructions:

'2. Create LinkedIn application at https://www.linkedin.com/secure/developer

    Enter your domain at JavaScript API Domain
    There is no need to enter OAuth Redirect URL'

Furthermore, it specifically has to be http://www.example.com/auth/linkedin/oauth2callback, unless I customize the files further. Either way, you can mark this as solved!
