Twitter JSON losing quotes around properties? - twitter

Question

Here's part of my JSON:
[
UserJSONImpl{
id=1489761876,
name='CharlesPerin',
screenName='charles_perin',
location='Paris,
France',
description='PhdStudentatINRIA-Univ.Paris-Sud-CNRS-LIMSI#infovis#dataviz#hci',
isContributorsEnabled=false,
profileImageUrl='http: //a0.twimg.com/profile_images/3766400220/bbced44afe69e60eb30e00f593a2f3b5_normal.jpeg',
profileImageUrlHttps='https: //si0.twimg.com/profile_images/3766400220/bbced44afe69e60eb30e00f593a2f3b5_normal.jpeg',
url='http: //t.co/eYSy04EzEk',
isProtected=false,
},
UserJSONImpl{
id=19671465,
name='KevinQuealy',
screenName='KevinQ',
location='NewYork,
NY',
description='AgraphicseditorattheNewYorkTimes.AdjunctatNYU#SHERP.ReturnedPeaceCorpsvolunteer.Bald,

talkstoomuch.',
isContributorsEnabled=false,
profileImageUrl='http: //a0.twimg.com/profile_images/2213326305/image_normal.jpg',
profileImageUrlHttps='https: //si0.twimg.com/profile_images/2213326305/image_normal.jpg',
url='http: //t.co/vb0j99kE3N',
isProtected=false,
...(cont)
This was returned directly from a call to twitter4j's lookupUsers:
long[] hundredIDs = new long[100];
org.json.JSONArray users = new org.json.JSONArray();
for(int a = 0; a < (int)((double)friendArray.length()/100 +1); a++)
{
for(int j = 100*a; j < 100*(a+1); j++)
{
hundredIDs[j-100*a] = Long.parseLong(friendArray.getString(j));
}
users = new org.json.JSONArray(twitter.lookupUsers(hundredIDs)); //lookup users in batches of 100
for(int k = 0; k < users.length(); k++)
{
org.json.JSONObject user = users.getJSONObject(k);
if(Long.parseLong(user.getString("followers_count")) >= 500)
{
String id = user.getString("id"); //get id for each JSONObject
friendArrayFiltered.add(id); //store ids in another array
}
}
For some reason, the JSON returned by my code doesn't have the standard quotes around the properties ("id"= ...., rather than id =...). It doesn't seem to be a problem of the Twitter API itself since their examples are in the correct format: https://dev.twitter.com/docs/api/1/get/users/lookup.
Does anyone know what the problem is?
Also, not sure if this is a consequence but when I attempt to access individual elements of the JSONArray (like JSONArray[0]), an error is returned saying JSONArray[0] is not a JSONObject. Is this linked to the above problem?

Answer 1

It's not JSON, it's actually generated by the UserJSONImpl#toString() method which is providing a textual representation for each of the User objects returned by the lookupUsers invocation.
As for your second problem, you cannot use the [] operator on Object types in Java so I'm a little unclear what you mean without further information.

I'm not sure why you are wrapping twitter4j objects in JSONArray and JSONObject objects - of course you may have a good reason for doing this that's not apparent in the question - but you can simply use the methods directly on the returned objects to get the information you need, for example:
final List<User> users = twitter.lookupUsers(hundredIDs);
for (User user : users) {
final int followersCount = user.getFollowersCount();
if (followersCount > 500) {
... etc...
