How to refresh token in Reddit Api with basic auth?

[bhargavjoshi]

I am using you library for performing authentication on reddit and posting on reddit but i can't refresh the token using your library.

To refresh token i use the following code, using this library (https://github.com/php-curl-class/php-curl-class)

 $accessTokenUrl = 'https://ssl.reddit.com/api/v1/access_token';
    $clientId = 'ClientID';
    $clientSecret = 'ClientSecret';
    $redirectUrl = "YourURL";

    $string = $clientId.":".$clientSecret;
    $val = base64_encode($string);
    $val = " Basic ".$val;

    $curl = new Curl();
    $curl->setOpt(CURLOPT_RETURNTRANSFER, TRUE);
    $curl->setOpt(CURLOPT_SSL_VERIFYPEER, FALSE);

    $curl->setHeader('Authorization', $val);

    $curl->post($accessTokenUrl, array(
        'client_id' => $clientId,
        'client_secret' => $clientSecret,
        'grant_type' => 'refresh_token',
        'refresh_token' => $refresh_token,
        'scope' => 'identity,edit,submit',
        'state' => 'refresh_token',
        'duration' => 'permanent',
        'redirect_uri' => $redirectUrl
    ));
    if (!$curl->error) {
        if ($curl->http_status_code == 200){
            $resp_data = json_decode($curl->response, 1);
            $data = array('error' => 0, 'data' => $resp_data);
            return $data;
        }else{
            $data = array('error' => 1);
            return $data;
        }
    }else{
        $data = array('error' => 1);
        return $data;
    }

Note: the api requires a Basic auth with client id as username and client secret as password.

It would be really great if you can help me implement refresh token with this library.

Sorry for opening ticket issue is solved.

$accessTokenUrl = 'https://ssl.reddit.com/api/v1/access_token';
$client = new OAuth2\Client($clientId, $clientSecret,
OAuth2\Client::AUTH_TYPE_AUTHORIZATION_BASIC);
$response = $client->getAccessToken($accessTokenUrl,
OAuth2\Client::GRANT_TYPE_REFRESH_TOKEN,array(
        'client_id' => $clientId,
        'client_secret' => $clientSecret,
        'grant_type' => 'refresh_token',
        'refresh_token' => $refresh_token,
        'scope' => 'identity,edit,submit',
        'state' => 'refresh_token',
        'duration' => 'permanent',
        'redirect_uri' => $redirectUrl
    ));

Hi bhargavjoshi, I am trying to implement the refresh token example in your latest comment. Can you please let me know what the $refresh_token variable should be set to? I don't see it in defined in your example.
