专辑信息

我已经完成了一些搜索，并且发现了一些与之相似的东西，但是我仍然在努力探索它的工作方式，并且努力了一些。

我试图发送请求来搜索艺术家，并使用jQuery跟踪Spotify API，然后从我收到的json中检索数据。

这是我的代码：

    $.ajax({
        url: "https://api.spotify.com/v1/search?q=" + song + "%20" + artist + "&type=track&limit=1",
        dataType: "json",
        success: function(data) {

            //data downloaded so we call parseJSON function 
            //and pass downloaded data
            var json = $.parseJSON(data);
            //now json variable contains data in json format
            //let's display a few items
            var trackName = json.items.name;
        },

        error: function() {
          console.log("Error retrieving spotify API");
        }
    });

在控制台中，它显示了这一点：

XHR finished loading: GET "https://api.spotify.com/v1/search?q=Ride%20Twenty%20One%20Pilots&type=track&limit=1".

这告诉我请求发送正确，json spotify响应是：

}
}

我试图检索以下信息并将它们保存到变量中：歌名，艺术家，专辑封面以及spotify上专辑的链接。

我试过使用

var trackName = json.tracks.items.name;

但控制台有这个错误：

(index):465 Uncaught TypeError: Cannot read property 'name' of undefined

当我看看这是什么时，它就是我试图在代码中设置变量的地方。

如果任何人都能指引我朝着正确的方向发展，或者对我有所帮助，那将非常感谢！

谢谢

尝试使用“data.tracks.items.name”，将工作。
