[Iplant-api-dev] token retrieval not working

[Duvick, Jonathan P [GDCBS]]

Thanks, you are right I forgot to add a statement to URL-encode the array (I used 'http_build_query' previously for this). The request now works.

I will note that 'CURLOPT_CUSTOMREQUEST' seems unnecessary in this context, so I've left it out.

You've got a couple php errors in your code and you're not serializing the form before passing it to curl. Try this code and remember to encode your password if it contains special characters. Also, check out the Agave php sdk.

<?php

$base_url = 'https://agave.iplantc.org';
$username = '';
$password = '';
$consumer_key = '';
$consumer_secret = '';
$post_params = array(
  "grant_type=password",
  "username=${username}",
  "password=${password}",
  "scope=PRODUCTION"
);

$query_string = implode('&', $post_params);
echo $query_string."\n";
$ch = curl_init();
$url="${base_url}/token";
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'Content-Type:application/x-www-form-urlencoded'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_USERPWD, "${consumer_key}:${consumer_secret}");
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POST, 4);
curl_setopt($ch, CURLOPT_POSTFIELDS, $query_string);
$response = curl_exec($ch);
$headerSent = curl_getinfo($ch, CURLINFO_HEADER_OUT );
echo $headerSent."\n";
echo $response."\n";

curl_close($ch);

?>

I'm refactoring an Atmosphere VM for Agave, accomplished via Web forms generated by PHP, and I've succeeded in getting step 1 (client app registration/retrieve keys) accomplished. Step 2 (retrieve auth token and refresh token) is not working. It always returns http_code '400' in response to my curl request, suggesting malformed syntax.

Can anyone spot a problem in this code? My client app ('xGDBvm') is successfully registered (it shows up onhttps://agave.iplantc.org/store/site/pages/applications.jag)<https://agave.iplantc.org/store/site/pages/applications.jag> and I am successfully passing the associated consumer key/_secret string values in the curl request after retrieving them from a MySQL table. In the snippet below, $base_url is  https://agave.iplantc.org.<https://agave.iplantc.org/>

    $ch = curl_init();
    $url="${base_url}/token";
    curl_setopt($ch, CURLOPT_URL,$url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, true);
    $credentials = "${consumer_key}:${consumer_secret}";
    curl_setopt($ch, CURLOPT_USERPWD, $credentials);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'Content-type: application/x-www-form-urlencoded'));
    $post_params = array(
    'grant_type'=>'password',
     'username'=>$username,
     'password'=>$password,
     'scope'=>'PRODUCTION'
    );
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_params);
    $response = curl_exec($ch);
    $resultStatus = curl_getinfo($ch);
