I'm trying to connect to an OAuth2 Provider using cURL in PHP 5. I established the initial authorization, and got that working fine.
However, I'm getting stuck with getting it to send me a token. I keep hitting the "unsupported_grant_type" error. This is my code so far:
$token_url = 'https://discordapp.com/api/oauth2/token';
if (!$code)
{
echo '<a href="'. $auth_url . '">Login with Discord</a>';
} else {
// cURL Request Goes Here.
$chB = curl_init();
$post_opts = array(
'client_id' => '[id_goes_here]',
'client_secret' => '[secret_goes_here',
'code' => $code,
'redirect_uri' => '[valid_redirect_uri_goes_here]',
'grant_type' => 'authorization_code',
);
$c_opts = array(
CURLOPT_URL => $token_url,
CURLOPT_POST => true,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_HTTPHEADER => array(
'Content-type: application/x-www-form-urlencoded',
),
CURLOPT_POSTFIELDS => $post_opts,
);
curl_setopt_array($chB, $c_opts);
$run_now = curl_exec($chB);
$code = curl_getinfo($chB, CURLINFO_HTTP_CODE);
curl_close($chB);
print($code);
var_dump($run_now);
}
As you can see, I'm sending the data post to the authorization_code grant type. $code is the returned code form the authorize endpoint. I also have my form data set as x-www-form-urlencoded.
Can someone please point me into the direction of what I'm doing wrong here?
I've searched for a few hours now on Google, SO, etc... I'm not seeing any fresh advice that's getting me anywhere else other than where I already am.
