// QQ音乐 URL 获取（直连）
|
||
// 接口: https://u.y.qq.com/cgi-bin/musicu.fcg
|
||
// 方法: vkey.GetVkeyServer.CgiGetVkey
|
||
// 取流方案：
|
||
// 按请求音质组 filename 候选链一次请求（命中第一个有 purl 的档位即最高可用音质）；
|
||
// 始终附带 C400{songmid}.m4a 保底（匿名可取的 128k）。
|
||
// 档位前缀（社区资料 2026-10 核对）：RS01 Hi-Res FLAC > Q000/AI00 大师/臻品母带 FLAC >
|
||
// F000 无损 FLAC > M800 320k MP3 > M500 128k MP3 > C400 128k AAC；
|
||
// VIP 档 filename 用 media_mid（非 songmid）。
|
||
// 登录 cookie（uin + qm_keyst，见 /login/tx）可解锁 320k/无损/Hi-Res。
|
||
// 统一接口约定：apis('tx').getMusicUrl(songInfo, type) → { promise, cancelHttp }
|
||
// promise resolve → { type, url }（type 为实际命中的音质，可能低于请求值）
