/* probe_track_all.c — 真机抓 /api/playlist/track/all 原始响应 + 用现有解析器解析。
|
||
* 目的：确认「Load Failed」根因（eapi 路由 / 响应字段 / code 非 200 / 数组路径）。
|
||
* 请求量：1（track/all for 一个小歌单）。
|
||
* 用法: probe_track_all <data_dir> <cacert> <playlist_id> <out_path> [path] [crypto]
|
||
* data_dir 默认 /usr/data/mnt/sd_0/MeowData/dev.player.ncm/data
|
||
* cacert 默认 /usr/data/mnt/sd_0/MeowAPPs/dev.player.ncm/cacert.pem
|
||
* playlist_id 默认 18206253175（Docu/1 首）
|
||
* out_path 默认 /tmp/track_all_raw.json
|
||
* path 默认 /api/playlist/track/all（eapi 已证 404，可改 /api/v6/playlist/track/all）
|
||
* crypto 0=eapi(默认) 1=weapi
