title: facebook graph api if a user has liked a page
body: <p>I am trying to use facebook graph api to find out if a user has liked a particular page.This is the query I tried</p>
  
  <pre><code>https://graph.facebook.com/user_id/likes/page_id?access_token="my access token"
  </code></pre>
  
  <p>I tried the same kind of query to find if two users are friends but its returning empty data set even for that.</p>
  
  <pre><code>https://graph.facebook.com/user_id/frineds/user_id
  </code></pre>
  
  <p>How should I solve that issue?</p>
