当我在 freebase 查询生成器中运行此查询时
[{
"/type/object/id": "/en/michael_jackson",
"/type/object/name": null,
"/type/object/type": "/music/artist",
"/music/artist/album": [{
"id": null,
"name": [],
"release_type!=": "Single",
"/music/album/primary_release": [{
"name": null,
"track_list": [{name:null}]
}]
}]
}];
我得到了正确的结果,包括专辑和曲目列表,但如果将查询更改为
[{
"/type/object/id": "/en/carly_rae_jepsen",
"/type/object/name": null,
"/type/object/type": "/music/artist",
"/music/artist/album": [{
"id": null,
"name": [],
"release_type!=": "Single",
"/music/album/primary_release": [{
"name": null,
"track_list": [{name:null}]
}]
}]
}];
我什么都拿不回来。您可以在http://www.freebase.com/queryeditor尝试这两个查询。有人能指出我做错了什么吗?这两位都是艺术家,所以我也应该找回 Carly Rae Jepsen 的专辑和曲目列表。
