如何使用echonest api获取特定歌曲的Spotify ID

Question

我试图用艺术家姓名和歌曲名称查询echonest，并让它返回歌曲的spotify ID。目前我只能让艺术家返回。

我正在读留档，但它毫无意义，我认为它可能是过时的，想知道是否有人能帮我。

这是我正在使用的文档的链接(http://developer.echonest.com/sandbox/spotify.html)API示例是上一个示例的第二个示例，即：

http://developer.echonest.com/api/v4/song/search?api_key=FILDTEOIK2HBORODV&format=json&results=1&artist=radiohead&title=karma%20police&bucket=id:spotify&bucket=tracks&limit=true

艺人：Radiohead歌曲标题：Karma Police

在文档中作为示例返回的是

songs: [
{
    title: "Karma Police"
    artist_name: "Radiohead"
    id: "SOHJOLH12A6310DFE5"
    tracks: [
              {
              "catalog": "spotify",
              "foreign_id": "spotify:track:3L7BcXHCG8uT92viO6Tikl",
              "id": "TRAVAWH13386461C1A"
              }    
           ]
  }
]   

我想得到Spotify：曲目：NUMBER_HERE

但当我在浏览器中实际运行api时，我得到了完全不同的结果。

我明白了

请有人给我指一下我正在俯瞰的方向好吗。

如有任何帮助、指导和建议，我们将不胜感激。我的最终状态是，我可以获得spotify曲目id，这样我就可以通过编程建立自己的播放列表。如果有更好的方法，我愿意接受建议

Answer 1

查看从The Echo Nest的API获得的响应，轨道URI位于response.songs[0]。轨道[0]。foreign_id。所以留档是正确的，只是它没有覆盖歌曲数组所在的响应对象。

希望这能有所帮助！
