Why is there an empty array in the response when using the fields field in the photos.getPhotos method?

Question

Classmates

In the photos.getPhotos method, I specify the list of requested fields in the fields parameter. In the response, an empty array comes in the photos parameter. What could be the problem?

Answer 1

I can share my working function here, I specially changed the application_key, so it is not working

function TSpamThread.API_photos_getPhotos: string;
varUA:String;
begin
if userAlbums.Count>0 then UA:=userAlbums[random(useralbums.Count)];
poststr:='gid='+api_gid+'&aid='+UA+'&fields=group_photo.*&count=50&application_key=CAFJIICABBABABA&format=json
&session_key='+sessionkey;
md5str:=sortmd5(poststr)+seskey;
md5str:=md5(md5str);
try
response.Text:=idhttp.Get(' api.odnoklassniki.ru/api/photos/getPhotos? '+poststr+'&sig='+md5str);
except exit; end;
albumPhotos.Text:=pasrsegroup('"id":"','"',response.Text);
if albumPhotos.Count>0 then result:=albumPhotos[random(albumPhotos.
end;
