Distinction between Oauth 2 and PHP Core API (PHP SDK)

Hi,

Thank you for your reply.

I'm not able to understand how to make the PHP curl call, what all curl parameters are to be set, etc. I'm not able to understand how to fetch the user auth token using the authorization API:

https://www.dropbox.com/developers/documentation/http/documentation#authorization

I'm using it like this. Please correct me:

$post['response_type'] = 'token';
$post['client_id'] = '6i45k3fi9a1i9an';
$post['redirect_uri'] = get_current_url().'&auth_callback=1';
$url = 'https://www.dropbox.com/oauth2/authorize';
// Set the curl parameters.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
//Set proxy 
//curl_proxy($ch);
// Turn off the server and peer verification (TrustManager Concept).
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post));

curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0.1) Gecko/20100101 Firefox/4.0.1');

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// Get response from the server.
$resp = curl_exec($ch); 
r_print($resp);

Hi,

I made the following changes:

function get_current_url() {
$url = @($_SERVER["HTTPS"] != 'on') ? 'http://'.$_SERVER["SERVER_NAME"] : 'https://'.$_SERVER["SERVER_NAME"];
$url .= ($_SERVER["SERVER_PORT"] != 80) ? ":".$_SERVER["SERVER_PORT"] : "";
$url .= $_SERVER["REQUEST_URI"];
return $url;
}
$url = 'https://www.dropbox.com/oauth2/authorize?response_type=token&client_id=6i45k3fi9a1i9an&redirect_uri='.get_current_url();
// Set the curl parameters.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
// Turn off the server and peer verification (TrustManager Concept).
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); 

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// Get response from the server.
$resp = curl_exec($ch);
echo '<br />Curl Error: '.curl_error($ch);
echo '<br />Curl Response: ';
r_print($resp);

Using this I get:

Invalid redirect_uri: "https://cpanel.nuftp.com:2083/cpsess5895978520/frontend/paper_lantern/softaculous/index.live.php": It must exactly match one of the redirect URIs you've pre-configured for your app (including the path).

How do I specify the redirect URL?

Also, I want to redirect this auth process in a separate window, which when accepted by the user should return back to the current window. How do I do that?
