title: yii eauth get access token
body: <p>I am using <a href="https://github.com/Nodge/yii-eauth" rel="nofollow">yii-eauth</a> in my Yii project. </p>
  
  <p>I am done with the login part. However, I faced a difficulty which is: Should I get the access token so that I can do extra things like post/share to facebook? There is a facebook-php-sdk, but I believe that this yii-eauth already has the functionality to get the access token.</p>
  
  <p>I tried the below code, but it returned an error saying <code>FacebookOAuthService and its behaviors do not have a method or closure named "getAccessToken".</code></p>
  
  <pre><code>$objFB=new FacebookOAuthService();
  echo $token_code=$objFB-&gt;getAccessToken("my_apps_client_id");
  </code></pre>
  
  <p>I am still new in yii-eauth. I hope someone may help me. Thanks.</p>
