- 撤销 3381e9b/1b972ec 中 jx/5s/bl/ap 四个短码,恢复 joox/5sing/bili/apple; qian→bd、migu→mg 保留 - 目录与文件对齐保留的新 id:sdk/qian/→sdk/bd/、sdk/migu/→sdk/mg/、 sdk/apis/qian.ts→bd.ts、migu.ts→mg.ts、src/http/migu-stream.ts→mg-stream.ts (规则改为「目录=对外 id」,聚合入口的模块变量同步更名;music.migu.cn 等域名、 上游 music-lib 对照注释、miguGet 等功能标识符不动) - 对外 id 全表:kw kg tx wy qs xm me qt lr mg bd joox 5sing bili apple **破坏性变更**:joox/5sing/bili/apple 四平台的 URL、/sources 返回与 data/auth.json 凭据键恢复全名,已存短码键的登录态需重新登录。 验证:typecheck ✓、pnpm test 112/112 ✓

// Apple Music 取流(上游 apple.go GetDownloadURL)
|
||
// ⚠️ Apple 只提供 **preview 试听片段**(audio-ssl.itunes.apple.com,AAC/m4a,约 30-90 秒,实测单文件 ~3MB),
|
||
// 完整曲目是 FairPlay DRM 加密流(extendedAssetUrls.enhancedHls),需要 gamdl 等外部工具解密,
|
||
// 本 SDK 不提供。因此这里**任何请求档位都返回 type='preview'**,并在注释/响应里明确标注,不假装是无损完整曲。
|
||
// 歌曲的 previews[0].url 来自 catalog 歌曲详情(搜索结果缓存里的 previewUrl 也会直接复用,同上游 s.URL 逻辑)。
|
||
// 统一接口约定:apis('apple').getMusicUrl(songInfo, type) → { promise, cancelHttp }
|

// type 请求参数不影响结果(只有 preview 一档);supportQualitys 声明为 ['128k'] 以对齐

// /sources 与 /url?quality 枚举,返回的实际档位以 type='preview' 为准。
