例如:
http://soundcloud.com/mhiqu3/sets/heretik/
如何获取缩略图网址:http://i1.sndcdn.com/artworks-000004897289-5r6ws9-large.jpg?1767646
使用api(或不使用)?

我知道这已经很老了,但是我偶然发现了这个问题寻找其他东西,我想给我两分钱。
这些都是可能的尺寸(来源API Reference):
* t500x500: 500×500 * crop: 400×400 * t300x300: 300×300 * large: 100×100 (default) * t67x67: 67×67 (only on artworks) * badge: 47×47 * small: 32×32 * tiny: 20×20 (on artworks) * tiny: 18×18 (on avatars) * mini: 16×16 * original: (originally uploaded image)

另外,如果将url字符串中的“-large”替换为“-t300x300”或“-t500x500”,您将可以访问更大的格式。

您可以使用/tracks
端点,并从返回的JSON中读取artwork_url
属性。更多详情:http://developers.soundcloud.com/docs/api/tracks
答案 3 :(得分:4)
你想要做的是使用Soundclouds API,如下所示:
SC.get(PATH, function (track, err){
IMG_URL = track.artwork;
});
你可以在这里看到一个例子:
http://runnable.com/UuiMCfATvMMkAAAS/get-a-tracks-artwork-on-soundcloud-in-javascript#
可以通过不同的方式获得轨道的PATH
1.如果您知道图像ID,您可以像这样抓住它
var PATH = "/tracks" + id;
2.如果你知道赛道的名称和用户
var PATH = "/users/dj-faze/tracks/phase-shift-360-019-degrees"
3.您还可以使用其他soundcloud API
注意:确保您尝试获取的曲目图像是公开的。如果它是私有的,您将必须使用soundcloud授权API登录。
答案 4 :(得分:3)
我尝试使用this answer但遗憾的是,SoundCloud似乎无法保证t500x500
,original
或其他尺寸不存在。
因此,我使用artwork_url
编写了一个快速应用程序,该应用程序重定向到其CDN上的最大可用图像。

它使用它们的命名方案并逐个枚举大小,直到某些图像返回状态200。
