spotify曲目的API中是否有某种通用ID？

Question

我正在Spotify API中为每个音轨寻找某种通用标识符。例如，如果我拿到迈克尔·杰克逊的曲目《颤栗者》，我会得到所有的曲目信息和Spotify自己的唯一标识符，但当你在杂货店结账和买香蕉时，我也会得到相当于4011的音乐。不管你去哪个商店，你总是打4011买香蕉。谢谢！

你想要的并不真正存在，但是有一个叫做ISRC的标识符，它可能非常接近你所要求的。

https://en.wikipedia.org/wiki/International_Standard_Recording_Code

这个Spotify轨道与uri Spotify：轨道： 2LlQb7Uoj1kKyGhlkBf9aC是迈克尔·杰克逊的惊悚片。该轨道的ISRC代码是USSM19902989，您可以在Web API中找到：

$ curl -s -X GET "https://api.spotify.com/v1/tracks/2LlQb7Uoj1kKyGhlkBf9aC" \
       -H "Accept: application/json" \
       -H "Authorization: Bearer <INSERT ACCESS TOKEN>" \
| jq -r .external_ids.isrc
USSM19902989

Yoy可以使用此标识符在Spotify（或其他服务）中查找迈克尔·杰克逊的《颤栗》。

$ curl -s -X GET "https://api.spotify.com/v1/search?q=isrc%3AUSSM19902989&type=track" \
       -H "Accept: application/json" \
       -H "Authorization: Bearer <INSERT ACCESS TOKEN>" \
| jq -c '.tracks.items[] | {uri, name, album: .album.name, available_markets}'

你在这里得到的是迈克尔·杰克逊的许多不同版本的惊悚片。它们在不同的市场上有售，来自不同版本的颤栗或迈克尔·杰克逊汇编。

ISRC代码USSM19902989可以说是唯一指向迈克尔·杰克逊的《颤栗》，但事实并非如此。它可能有不止一个ISRC代码。用你的类比，4011总是指向香蕉，但是可能有更多的代码指向同一个香蕉。虽然这听起来不像是个问题，但实际上是个问题。不同的轨道数据库不包含相同的ISRC。因此，虽然4011总是指向香蕉而不是其他，但USSM19902989总是指向颤栗而不是其他。然而，在一些商店4011并不指向任何东西。

我在这里描述的使用ISRC的方法是可行的，但有点烦人。如果您只为Spotify用户编写应用程序，使用Spotify Web API，则无需关心市场可用性或ISRC，只需发送Spotify track URI即可。例如，spotify:track:2LLQB7UOJ1KKKYGHLKBF9AC在德国似乎不可用。然而，如果德国Spotify用户尝试播放这首曲目，他们仍然会听到迈克尔·杰克逊的《颤栗》，因为Spotify将播放另一首可用的曲目，如Spotify:track:3S2R0EVwBSAVMd5UMgKTL0。
