如何从spotify npm包中提取数据？我越来越不清楚了 ========================这是我下面的代码========================= 函数spotifyThisSong（）{ var spotify=新spotify({ id:“myid”， 秘密：“我的秘密” }); var songName=process.argv[3]； 如果（！songName）{ songName=“我又多大了”； } var params=songName； search（{type:'track'，query:params}，函数（err，data）{ 如果（错误）{ log（'发生错误：'+err）； return；//来自spotify npm文档 } 否则{ 控制台日志（数据）； }; }); } ============================代码结束========================= 一直给我不确定的感觉。我需要提取歌曲名称，年份，专辑和它的网址。提前谢谢。

不可读，请正确格式化。您好，欢迎使用StackOverflow。请花些时间阅读帮助页面，特别是命名和的部分。更重要的是，请阅读。您可能还想了解。我很抱歉在没有编辑的情况下发布得太快。我希望这个版本更好。 ===================This is my code below========================= function spotifyThisSong() { var spotify = new Spotify({ id: 'myid', secret: 'mysecret' }); var songName = process.argv[3]; if(!songName){ songName = "What's my age again"; } var params = songName; spotify.search({ type: 'track', query: params }, function(err, data) { if ( err ) { console.log('Error occurred: ' + err); return; //from spotify npm docs } else{ console.log(data); }; }); } ===================END OF CODE========================= keeps giving me undefine. I need to extract the song name, year, album and its url. Thanks in advance.

  //So this is what I found.  This actually involves a few things.
  //FIRST, capture user-input,
  //SECOND, npm install spotify, and use the template as suggested in the DOCS. 
  //THIRD, parse through the JSON correctly as done below.

  //HOPE this helps someone.  (dont forget your keys from spotify)


  var songName = process.argv[3]; //capture userInput and query it below 

 params = songName;
    spotify.search({ type: 'track', query: params }, function(err, data) {
        if ( err ) {
            console.log('Error occurred: ' + err);
            return;  
        }
        else{
            output = space + "================= DATA HERE ==================" + 
            space + "Song Name: " + "'" +songName.toUpperCase()+ "'" +
            space + "Album Name: " + data.tracks.items[0].album.name +
            space + "Artist Name: " + data.tracks.items[0].album.artists[0].name +  
            space + "URL: " + data.tracks.items[0].album.external_urls.spotify + "\n\n\n";
            console.log(output);    
            };
    });
