How to get Facebook post likes? - facebook-graph-api

Question

I Am trying to retrieve FB Post Likes and Reactions using Graph API. The code that I used to retrieve the 'LIKE','LOVE','HAHA' of a post is shared below.
<script type="text/javascript">
var postID = '';
var access_token = '';
var refreshTime = 1;
var defaultCount = 0;
var reactions = ['LIKE', 'LOVE', 'HAHA'].map(function (e) {
var code = 'reactions_' + e.toLowerCase();
return 'reactions.type(' + e + ').limit(0).summary(total_count).as(' + code + ')'
}).join(',');
function refreshCounts() {
var url = 'https://graph.facebook.com/v2.8/?ids=' + postID + '&fields=' + reactions + '&access_token=' + access_token;
$.getJSON(url, function(res){
var v1 = res[postID].reactions_like.summary.total_count;
var v2 = res[postID].reactions_love.summary.total_count;
var v3 = res[postID].reactions_haha.summary.total_count;
$('#counter1').text(v1);
$('#counter2').text(v2);
$('#counter3').text(v3);
});
}
$(document).ready(function(){
setInterval(refreshCounts, refreshTime * 3000);
refreshCounts();
});
</script>
But the code showing two {} instead of the result.

Why don't you using javascript SDK?
var postID = $('#post_id').val();
FB.api(
'/' + postID + '/',
'GET',
{
"fields": "reactions.type(LIKE).limit(0).summary(1).as(like),reactions.type(WOW).limit(0).summary(1).as(wow),reactions.type(SAD).limit(0).summary(1).as(sad),reactions.type(LOVE).limit(0).summary(1).as(love),reactions.type(HAHA).limit(0).summary(1).as(haha),reactions.type(ANGRY).limit(0).summary(1).as(angry)",
"access_token": "token"
},
function (response) {
console.log(response);
var like_count = response.like.summary.total_count;
var love_count = response.love.summary.total_count;
var wow_count = response.wow.summary.total_count;
var haha_count = response.haha.summary.total_count;
var sad_count = response.sad.summary.total_count;
var angry_count = response.angry.summary.total_count;
}
);
This worked for me
