Spotify API頂級曲目中斷

我試圖從藝術家處獲得第一個頂級預覽網址，但每次我搜索時都會返回一個破碎的json。我可以將它解析爲一個字符串來獲取我需要的內容，但是json會更容易。這裏是我的代碼：Spotify API頂級曲目中斷

const https = require('https'); 
var open = require('open') 

function songError(){ 
    console.log('There was some kind of error fetching your artist ;('); 
} 

function getTopSong(p_id){ 
    https.get('https://api.spotify.com/v1/artists/'+p_id+'/top-tracks?country=BR', function(res){ 
     res.on("data", function(chunk){ 
      var json = JSON.parse(chunk.toString('utf8')); 
      console.log(json); 
     }); 
    }); 
} 

function getArtistID(p_name) { 
    https.get('https://api.spotify.com/v1/search?q='+encodeURI(p_name)+'&type=artist', function(res){ 
     res.on("data", function(chunk) { 
      var json = JSON.parse(chunk.toString('utf8')); 
      if(json['artists']['items'][0]['id'] != undefined || json['artists']['items'][0]['id'] != null){ 
       console.log('id: ',json['artists']['items'][0]['id']); 
       getTopSong(json['artists']['items'][0]['id']); 
      }else 
      { 
       songError(); 
      } 
     }); 
    }); 
} 

getArtistID("rage against the machine");

似乎是在管線329錯誤：

undefined:329 
    "available_markets" : [ "AR", "AU", "AT", "BE", "BO", "BR", "BG", "CA", "CL", "CO", "CR", "CY", "CZ", "DK", "DO", "DE", "EC", "EE", "SV", "FI", "FR", "GR", "

我的問題是，我是不是做錯了什麼或者是不是真的壞了？謝謝！

我至少可以捲曲它沒有任何問題：

$ curl -s 'https://api.spotify.com/v1/artists/2d0hyoQ5ynDBnkvAbJKORj/top-tracks?country=BR' | python -mjson.tool | tail 
      "id": "25CbtOzU8Pn17SAaXFjIR3", 
      "name": "Take The Power Back - Remastered", 
      "popularity": 58, 
      "preview_url": "https://p.scdn.co/mp3-preview/b44e8f96a219871587d0559970ca5dce71c891f2", 
      "track_number": 3, 
      "type": "track", 
      "uri": "spotify:track:25CbtOzU8Pn17SAaXFjIR3" 
     } 
    ] 
}

我不很瞭解的NodeJS，但你不需要連接所有回調res.on（「數據」

？

https://nodejs.org/api/http.html#http_http_request_options_callback

https.get('https://api.spotify.com/v1/artists/' + p_id + '/top-tracks?country=BR', function(res) { 
    var body = []; 
    res.on("data", function(chunk) { 
    body.push(chunk); 
    }); 
    res.on("end", function() { 
    var json = JSON.parse(Buffer.concat(body).toString("utf8")); 
    console.log(json); 
    }); 
});

如果響應是長和Spotify的服務器決定發回塊傳輸編碼的響應，則HTTP的NodeJS模塊可能拆分RES也要打起精神來。

就是這樣，我忘了將它連接在一起，愚蠢的錯誤！謝謝！ –

我剛剛意識到它可能與服務器的分塊傳輸編碼無關。無論如何，api可能會將身體分割爲塊，因此您可以下載千兆字節而不必將所有內容都讀入內存。 – jooon
