业主编号：3734832
我正在使用这段代码：
$res = file_get_contents('https://api.vk.com/method/likes.getList?type=photo&owner_id='3734832'&page_id='98429809'&page_url=http://vk.com/id98429809?z=photo98429809_299166823%2Falbum98429809_0%2Frev');
$resp = json_decode($res, true);
echo 'Count Likes: '.$resp['response']['count'];
但我有一个错误：
{"error":{"error_code":100,"error_msg":"One of the parameters specified was missing or invalid: item_id is undefined","request_params":[{"key":"oauth","value":"1"},{"key":"method","value":"likes.getList"},{"key":"type","value":"photo"},{"key":"owner_id","value":"3734832"},{"key":"page_id","value":"98429809"},{"key":"page_url","value":"http:\/\/vk.com\/id98429809?z=photo98429809_299166823\/album98429809_0\/rev"}]}}
如何获取所有喜欢该照片的用户 ID？
请告诉我错误在哪里？
