[OpenSocial] How can I use filter field, when get viewerfriends cross osapi.people.get

[lipeng]

When I use opensocial 0.8, my code is follow
<code>
     var opts = {};
     opts[opensocial.DataRequest.PeopleRequestFields.PROFILE_DETAILS]
=
                     [opensocial.Person.Field.AGE,
                     opensocial.Person.Field.NAME];
     opts[opensocial.DataRequest.PeopleRequestFields.SORT_ORDER] =
opensocial.DataRequest.SortOrder.NAME;
     opts[opensocial.DataRequest.PeopleRequestFields.FILTER] =
opensocial.DataRequest.FilterType.HAS_APP;
     function initData() {
       var req = opensocial.newDataRequest();
       req.add(req.newFetchPeopleRequest('VIEWER_FRIENDS', opts),
'viewerFriends');
       req.send(render);
     }
</code>
When I use openscial 0.9, I didn't know what will I do use osapi
method (container is shindig php version).
<code>
=============
     var opts = {};
     opts[opensocial.DataRequest.PeopleRequestFields.PROFILE_DETAILS]
=
                     [opensocial.Person.Field.AGE,
                     opensocial.Person.Field.NAME];
     opts[opensocial.DataRequest.PeopleRequestFields.SORT_ORDER] =
opensocial.DataRequest.SortOrder.NAME;
     opts[opensocial.DataRequest.PeopleRequestFields.FILTER] =
opensocial.DataRequest.FilterType.HAS_APP;
==============
       var fields =
['id','age','name','gender','profileUrl','thumbnailUrl'];
       var batch = osapi.newBatch();
       batch.add('viewerFriends',
osapi.people.getViewerFriends(opts));
       batch.execute(render);
</code>
the code between "========", did not work well.

What can  I do ?
