Python streamble为false的soundcloud曲目的流URL

有一个属性“streamable”的一个轨道，如果是“false”，我无法获得该轨道的stream_url

但我看到很少有下载者能得到同一首歌的流url，然后得到那首歌的cdn链接

我甚至对我的应用程序进行了身份验证，但没有找到流的url。这就是我所做的

import soundcloud

# create client object with app credentials
client = soundcloud.Client(client_id='YOUR_CLIENT_ID',
                           client_secret='YOUR_CLIENT_SECRET',
                           redirect_uri='REDIRECT_URL')

# exchange authorization code for access token
code = params['code']
access_token = client.exchange_token(code)

#'YOUR_ACCESS_TOKEN' is access_token which I got in above step.
client = soundcloud.Client(access_token='YOUR_ACCESS_TOKEN')

track = client.get('/tracks/161730338')

下面是轨迹对象

>track.__dict__

根据文档，我应该从

# get the tracks streaming URL
stream_url = client.get(track.stream_url, allow_redirects=False)

# print the tracks stream URL
print stream_url.location

我被困在这里四天了。有没有办法获得MP3曲目的最终cdn链接，或者这些SoundCloudDownLader是如何做到的。

如果

stream\u url

键返回空值，我发现

streams

端点将返回有效的url

HTTP GET: https://api.soundcloud.com/tracks/[TRACK_ID]/streams?client_id=[YOUR_CLIENT_ID]

免责声明：这是一个未记录的端点，SoundCloud随时可能对其进行更改。

HTTP GET: https://api.soundcloud.com/tracks/161730338/streams?client_id=[YOUR_CLIENT_ID]

}

preview\u mp3\u 128\u url

键值对具有所需的128kbps流媒体mp3

如果

预览\u mp3\u 128\u url

不是完整曲目，则需要使用ffmpeg等工具下载HLS传输流

ffmpeg -i "https://ec-hls-media.soundcloud.com/playlist/EDiPRlpWkJ2V.128.mp3/playlist.m3u8?f10880d39085a94a0418a7e062b03d52bbdc0e179b82bde1d76ce6ad1a416907458c1576abbf27bccb1984bf2890809c25cb2c95f826eba5858b2322a2cc08c48f3664ebef63724f43e9baa7d819586e497b7175430826823cbebd16" -c copy test.ts

这将为您提供完整的mp3曲目文件

它唯一的问题是，它是一个预览曲目，这意味着该曲目的播放时间大约为1分钟duration@vaibhav1312更新了我的答案以显示如何下载HLS流文件，这是完整的曲目。@vaibhav1312我找到了另一种总是返回http mp3 url的方法。请看我的答案：可能重复的
