Question

我最近一直在浏览器中使用ajax来使用spotify api，到目前为止我还没有遇到任何问题。但是现在我尝试将它与node.js一起使用，我只是做一个简单的get并尝试将字符串解析为JSON对象，但是我得到了一个语法错误。这是代码：

var https = require('https')

var dir = "https://api.spotify.com/v1/search?query=tania+bowra&offset=0&limit=20&type=artist"
https.get(dir, function (response){
    response.setEncoding('utf8');
    response.on('data', function (data){
        var str = data;
        var jObj = JSON.parse(str);
        console.log(jObj);
    })
})

这是我收到的响应，并希望将其解析为Json对象：

{
    "artists": {
        "href": "https://api.spotify.com/v1/search?query=tania+bowra&offset=0&limit=20&type=artist",
        "items": [
            {
                "external_urls": {
                    "spotify": "https://open.spotify.com/artist/08td7MxkoHQkXnWAYD8d6Q"
                },
                "followers": {
                    "href": null,
                    "total": 21
                },
                "genres": [],
                "href": "https://api.spotify.com/v1/artists/08td7MxkoHQkXnWAYD8d6Q",
                "id": "08td7MxkoHQkXnWAYD8d6Q",
                "images": [
                    {
                        "height": 640,
                        "url": "https://i.scdn.co/image/f2798ddab0c7b76dc2d270b65c4f67ddef7f6718",
                        "width": 640
                    },
                    {
                        "height": 300,
                        "url": "https://i.scdn.co/image/b414091165ea0f4172089c2fc67bb35aa37cfc55",
                        "width": 300
                    },
                    {
                        "height": 64,
                        "url": "https://i.scdn.co/image/8522fc78be4bf4e83fea8e67bb742e7d3dfe21b4",
                        "width": 64
                    }
                ],
                "name": "Tania Bowra",
                "popularity": 4,
                "type": "artist",
                "uri": "spotify:artist:08td7MxkoHQkXnWAYD8d6Q"
            }
        ],
        "limit": 20,
        "next": null,
        "offset": 0,
        "previous": null,
        "total": 1
    }
}

这是我得到的错误：

undefined:16


SyntaxError: Unexpected end of input

    at IncomingMessage.<anonymous> (C:\path:12:19)
    at IncomingMessage.emit (events.js:107:17)

    at resume_ (_stream_readable.js:730:3)
    at _stream_readable.js:717:7

浏览器中的相同请求完美无缺，并且在http://jsonlint.com/

中签入时，Json格式中没有出现任何错误

将收到每个数据块调用'data'回调函数，因此您必须收集所有数据然后解析它：

https.get(dir, function (response){
  var str = '';
  response.setEncoding('utf8');
  response.on('data', function (data){
    str += data;
  });
  response.on('end', function (){
    var jObj = JSON.parse(str);
    console.log(jObj);
  });
})

尝试将spotify响应字符串解析为node.js中的json对象
