disqus support

I am trying to support login with Disqus (www.disqus.com). I think I have everything write and it logs me in fine. I see a URL coming back

I set the following:

case 'Disqus':
$this->oauth_version = '2.0';
$this->dialog_url = 'https://disqus.com/api/oauth/2.0/authorize/?client_id={CLIENT_ID}&scope={SCOPE}&response_type=code&redirect_uri={REDIRECT_URI}&state={STATE}';

$this->access_token_url = 'https://disqus.com/api/oauth/2.0/access_token';

I am quite sure it is authorizing me fine as I go to disqus and am logged in.

The problem I have is that it sends back a 302 code and unable to get token. if i ignore the 302 authorization->error, it still sees the token response as empty

If anyone has any ideas or has tested on Disqus I would greatly appreciate it.

I tried it here and it works. Are you sure you did not switch the public by the secret key?

If not, it is better to enable debugging and show what appears in your PHP error log.

Hi Manuel,
Thanks for getting back to me. Your code is working great for me on the out-of-the-box servers. I tryed swapping the two keys and got a invalid client id response, so I think I had them correct. Perhaps you can send your case: 'Disqus' code, maybe i have some error there. Here is the error log. I am sure I am doing something stupid :-(

You are missing a slash / at the end of the access token URL. That is why Disqus API is redirecting the access token request to the correct URL. The class does not handle the redirect because it is a POST request and redirects are GET requests, so it would not work.

Hi Manuel,

I got it working and getting tokens and profiles etc ! Thanks. I had a little trouble getting the API call working (passing the api_key to it) and tried to pass api key thru the array() parameter after 'GET'. It did not work. However the brute force approach below worked. Let me know if there is a better way to do the actual API call.

Thanks again for the wonderful library.

$success = $client->CallAPI(
'https://disqus.com/api/3.0/users/details.json?api_key='.$client->client_id,
'GET', array(), array('FailOnAccessError'=>true), $user);

Mike

Sorry for the delay. I am not sure what you mean by brute force. You're call to CallAPI looks fine.
