我对节点还不熟悉，我正在通过node.js处理一个API调用，我有点搞不懂为什么会这样。我已经通过节点轻松地完成了其他API调用，因为很容易找到如何针对各个字段等。但是我从来没有得到过与spotify API的链接，我也不明白data.tracks.items.artists.name是如何给我命名的？

我知道这是一个无知的问题，但我真的很想了解它是如何工作的，而不仅仅是让它发挥作用。

function song() {
var nodeArgs = process.argv;
var SongName = "";
for (var i = 3; i < nodeArgs.length; i++) {
    if (i > 3 && i < nodeArgs.length) {
        SongName = SongName + "+" + nodeArgs[i];
    }
    else {
        SongName += nodeArgs[i];
    }
}

var Spotify = require('node-spotify-api');
var spotify = new Spotify({
    id: "id",
    secret: "secret"
});

spotify.search({ type: 'track', query: SongName, limit: 1 }, function (err, data) {
    if (err) {
        SongName = "";
        console.log("Artist: " + songData.artists[0].name);
        console.log("Song Title: " + songData.name);
        console.log("Preview Track: " + songData.preview_url);
        console.log("Album: " + songData.album.name);
        song();
    }

    for (var i = 0; i < data.tracks.items.length; i++) {
        var songData = data.tracks.items[i];
        console.log("Artist: " + songData.artists[0].name);
        console.log("Song Title: " + songData.name);
        console.log("Preview Track: " + songData.preview_url);
        console.log("Album: " + songData.album.name);
    }
});
}

简而言之-- track端点使用同样包含艺术家对象的Object Model进行响应--这是一个艺术家对象数组，其中艺术家对象包含键name。

参考文献：https://developer.spotify.com/documentation/web-api/reference/tracks/get-track/

从他们的API文档

获取https://api.spotify.com/v1/tracks/{id}

响应对象包含

KEY VALUE       | TYPE                   | VALUE DESCRIPTION
---
artists         | an array of simplified | The artists who performed the track. 
                | artist objects         | information about the artist.

艺术家对象

artist object (simplified)

KEY VALUE       | TYPE                   | VALUE DESCRIPTION
---
external_urls   | an external URL object | Known external URLs for this artist.
href            | string                 | A link to the Web API endpoint providing full details of the artist.
id              | string                 | The Spotify ID for the artist.
name            | string                 | The name of the artist
type            | string                 | The object type: "artist"
uri             | string                 | The Spotify URI for the artist.
