feat(sdk): 新增咪咕/千千/JOOX/哔哩哔哩/5sing/Apple Music 六平台
平台注册表由 9 个扩到 15 个,同时补齐 sdk/types.ts 的类型与 OpenAPI 文档里的能力位声明。 - migu:命中 Z3D/I3D 加密候选时不返回直链,改由服务端解密代理出流, SDK 侧只负责登记票据,避免客户端拿到无法播放的密文 - apple:只提供 preview 试听片段(完整曲为 DRM),标 noAggregate 排除在跨平台精确匹配之外,防止用它顶掉其它平台的可播结果 - 其余平台按既有 PlatformModule 约定实现搜索/专辑/歌单/歌词 为什么合并成一次提交:六平台共用同一份注册表与能力位声明, 拆开会产生互相引用、单独无法通过类型检查的中间态。

// 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 }
|
||||
// promise resolve → { type:'preview', url, ext:'m4a', preview:true, songDuration, isrc }
|
||||
// (songDuration 是歌曲完整时长,试听片段本身约 30-90 秒)
|
||||
// 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。
