如何从Facebook图形API中的给定图形URL获取数据

Question

Here is the Javascript:

The purpose of this code is to get Number of user's posts in last 3 Months.

FB.api('/me/photos?fields=created_time&since=2013-03-28', function(response){
        dLen = response.data.length;
        if(!response.paging.next){
            dLenContent = "<div><span class='left'>"+i+++".</span><span class='mid'>  Number of times tagged in photos: </span><span class='right'>"+dLen+"</span></div>";
        }
        else{
            nextURL = response.paging.next;
            while(nextURL){
                graphURL = nextURL;
                ---------------------------------------
                ---How to fetch data from next page(graphURL)?---
                ---------------------------------------
                dLen = dLen + response.data.length;
                nextURL = response.paging.next;
            }
        }
        pInfo = document.getElementById("personalInfo");
        pInfo.innerHTML += dLenContent;
    });

In case there is next page, the else part of the code will be executed. In that else part, I have written one while loop which will be active until the is next page in the object we get.

I want to know get data of "response.paging.next"?

This is just a 2 steps thing

1. Parse the next/previous URL from the response. You can do it yourself or one of the many libraries

2. With the timestamp parsed, just call your function recursively and "since" in the Graph URL.

   function getFBData(date) { FB.api('/me/photos?fields=created_time&since=' + date, function(response){ var pager = "parse the paging data from facebook" getFBData(pager); }); }
