使用 janrain 从令牌中解码信息

Question

我在我的网站上使用 janrain 小部件进行 OAuth 流程。我正在以下 URL 中对此进行测试：http://vignesh.gvignesh.org/register/

单击注册按钮后，用户从 Google 或 Yahoo 或 Facebook 登录。我能够获取令牌并将其存储在变量中。我在我的站点中显示令牌以进行测试。现在我不知道如何从我得到的令牌中提取用户信息。

<?php

$rpxApiKey = 'YOUR_API_KEY_HERE';

if(isset($_POST['token'])) {

  /* STEP 1: Extract token POST parameter */
  $token = $_POST['token'];

  /* STEP 2: Use the token to make the auth_info API call */
  $post_data = array('token' => $_POST['token'],
                     'apiKey' => $rpxApiKey,
                     'format' => 'json');

  $curl = curl_init();
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($curl, CURLOPT_URL, 'https://rpxnow.com/api/v2/auth_info');
  curl_setopt($curl, CURLOPT_POST, true);
  curl_setopt($curl, CURLOPT_POSTFIELDS, $post_data);
  curl_setopt($curl, CURLOPT_HEADER, false);
  curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
  $raw_json = curl_exec($curl);
  curl_close($curl);


  /* STEP 3: Parse the JSON auth_info response */
  $auth_info = json_decode($raw_json, true);

  if ($auth_info['stat'] == 'ok') {

    /* STEP 3 Continued: Extract the 'identifier' from the response */
    $profile = $auth_info['profile'];
    $identifier = $profile['identifier'];

    if (isset($profile['photo'])) {
      $photo_url = $profile['photo'];
    }

    if (isset($profile['displayName'])) {
      $name = $profile['displayName'];
    }

    if (isset($profile['email'])) {
      $email = $profile['email'];
    }

    print $identifier;
        echo "</br>";
    print $photo_url;
        echo "</br>";
    print $name;
        echo "</br>";
    print $email;
    /* STEP 4: Use the identifier as the unique key to sign the user into your system.
This will depend on your website implementation, and you should add your own
code here.
*/

/* an error occurred */
} else {
  // gracefully handle the error. Hook this into your native error handling system.
  echo 'An error occured: ' . $auth_info['err']['msg'];
}
}
?>

这将从我们在身份验证后获得的令牌中提取信息。
