"""酷狗音乐 取流（对应 sdk/apis/kg.ts）。
|
||
|
||
通道：`https://gateway.kugou.com/v5/url`（x-router: trackercdn.kugou.com，android 签名）。
|
||
登录后自动带 token/userid（见 /login/kg）；匿名仅能取部分免费资源，VIP/受限资源返回 status:2。
|
||
音质映射：128k→128、320k→320、flac→flac、flac24bit→high。
|
||
成功响应播放地址在顶层 url: string[] 与 backupUrl: string[]；旧 data:[{url}] 仅作兼容兜底。
|
||
album_audio_id 传 NaN 会被网关拒答，必须归零。
|
||
|
||
注意：TS 原实现在这里 `getDevice()` + `androidSign`，但那两个函数在 `sdk/auth/kg.ts`，
|
||
Python 侧 `app/sdk/auth/kg.py` 仍是 stub（不在本次写入范围），因此设备指纹与签名
|
||
改为 `app/sdk/platforms/kg/util.py` 的实现 —— 算法逐字一致，指纹同样落在
|
||
`auth.json` 的 `_kg_device`，与登录态共用。
