seems Facebook changed the result of posts, few weeks ago it was possible to read the comment count from the post directly
https://graph.facebook.com/125909647492772_502
Try the following:
{
"data": [
{
"id": "447235535389660_1226199",
"from": {
"name": "Harjeet Walia",
"id": "100004980601083"
},
"message": "Price",
"can_remove": false,
"created_time": "2013-09-06T10:39:01+0000",
"like_count": 0,
"user_likes": false
},
{
"id": "447235535389660_1226152",
"from": {
"name": "Shoba Dhyani Jakhmola",
"id": "100000906896060"
},
"message": "baap re kitna mehnga !",
"can_remove": false,
"created_time": "2013-09-06T10:05:09+0000",
"like_count": 0,
"user_likes": false
}
],
"paging": {
"cursors": {
"after": "MQ==",
"before": "NA=="
}
}
}
then
int commentCount = .path("comments").path("data").size();
Here commentCount
will give the number of comments.
