How to get page total count of page likes in facebook api v2.8
<p><a href="https://developers.facebook.com/docs/graph-api/reference/v2.8/object/likes" rel="nofollow noreferrer">https://developers.facebook.com/docs/graph-api/reference/v2.8/object/likes</a></p>

<p>total_count property: Total number of people who liked. This is only returned when the flag summary=true is set.</p>

<p>I am wondering where to set summary=true</p>

<p>I am using FB node module</p>

<p>Following is my code snippet</p>

<pre><code>FB.api('xxxxx', {
    fields: ['id', 'name', 'likes', 'checkins', 'talking_about_count'],
    access_token: accessToken
}, function(res) {
    console.log(res);
});
</code></pre>
