Question

I want to parse JSON data which is coming in like:

{
   "212315952136472": {
      "id": "212315952136472",
      "name": "Ready",
      "picture": "http://profile.ak.fbcdn.net/hprofile-ak-snc4/195762_212315952136472_4343686_s.jpg",
      "link": "http://www.hityashit.com/movie/ready",
      "likes": 5,
      "category": "Movie",
      "description": "Check out the reviews of Ready on  http://www.hityashit.com/movie/ready"
   }
}

The code I am using is:

JSONElement userJson = JSON.parse(jsonResponse)
userJson.data.each {
    Urls = it.link
}

But I am not able to get anything assigned to Urls. Any suggestions?

That response is a Map, with a single element with key ‘212315952136472’. There’s no ‘data’ key in the Map. If you want to loop through all entries, use something like this:

JSONObject userJson = JSON.parse(jsonResponse)
userJson.each { id, data -> println data.link }

If you know it’s a single-element Map then you can directly access the link:

def data = userJson.values().iterator().next()
String link = data.link

And if you knew the id (e.g. if you used it to make the request) then you can access the value more concisely:

String id = '212315952136472'
...
String link = userJson[id].link
