通过 spotify API 提取 Preview_Url

Question

好吧，我打算通过 Spotify API 提取函数 preview_url，但我无法在代码后面找到这个函数，所以我来寻求您的帮助。

"preview_url" : "https://p.scdn.co/mp3-preview/5dcd99cf811094408dcfc1befe014495d786dab5",

{
  "artists" : {
    "href" : "https://api.spotify.com/v1/search?query=MAROON+5+ANIMALS&offset=0&limit=1&type=artist",
    "items" : [ ],
    "limit" : 1,
    "next" : null,
    "offset" : 0,
    "previous" : null,
    "total" : 0
  },
  "tracks" : {
    "href" : "https://api.spotify.com/v1/search?query=MAROON+5+-+ANIMALS&offset=0&limit=1&type=track",

    "limit" : 1,
    "next" : "https://api.spotify.com/v1/search?query=MAROON+5+-+ANIMALS&offset=1&limit=1&type=track",
    "offset" : 0,
    "previous" : null,
    "total" : 99
  }
}

让我达到所需功能的代码

$get_json->tracks->items[0]->artists[1]->external_urls->preview_url;

你能帮帮我吗？谢谢！

Answer 1

您似乎没有找到preview_url 值的正确路径。实际路径是tracks->items[0]->preview_url。希望这在某种程度上有所帮助。
