我正在尝试从 last.fm 中提取一些数据.

我收到以下回复:

{
"tracks": {
    "track": [
        {
            "name": "Once Upon a Dream",
            "duration": "203",
            "loves": "738",
            "mbid": "92078817-2e04-4bcd-9c43-ebb9c2d1823c",
            "url": "http://www.last.fm/music/Lana+Del+Rey/_/Once+Upon+a+Dream",
            "streamable": {
                "#text": "0",
                "fulltrack": "0"
            },
            "artist": {
                "name": "Lana Del Rey",
                "mbid": "b7539c32-53e7-4908-bda3-81449c367da6",
                "url": "http://www.last.fm/music/Lana+Del+Rey"
            },
            "image": [
                {
                    "#text": "http://userserve-ak.last.fm/serve/34s/96432461.png",
                    "size": "small"
                },
                {
                    "#text": "http://userserve-ak.last.fm/serve/64s/96432461.png",
                    "size": "medium"
                },
                {
                    "#text": "http://userserve-ak.last.fm/serve/126/96432461.png",
                    "size": "large"
                },
                {
                    "#text": "http://userserve-ak.last.fm/serve/300x300/96432461.png",
                    "size": "extralarge"
                }
            ]
        }

等等...

问题在于尝试访问回复的图像部分时，图像对象似乎有 #text作为我试图访问的信息的变量名称。正常response.tracks.track[i].image[0].text显然不起作用。

有什么特殊的方法来访问这个变量吗？

Answer 1

您可以使用the square bracket notation像这样访问该变量:

response.tracks.track[i].image[0]['#text']
