用户报"歌曲源全部失效"。逐层实测结论：**不是代码 bug，是源站对该出口 IP 的授权窗口失效**。 实测证据（本机与设备同一出口 IP 188.253.112.231，设备 LAN 192.168.100.177/.83、本机 .203）: - i.php 仍认证通过: code=200 / end_date=2026-10-05 / ordertype=0 / retry=5； - do.php 对**每一首歌**（包括不存在的编号 1111111、9999999）都返回**同一个**资源 https://wb66.cn/f/d/7b7c9/10188555.ts —— 而 wb66 正是代码里早就标注的广告/测试资源域名； - 换全新随机设备身份(mac/sn)结果相同 → 限制记在**出口 IP** 上，与设备无关； - 7 个 host × ls=1~3 × (720/1080, h265 0/1) 全组合探测：0 个返回真源； - mwsLogin 返回 authorized:true，但 license_box_count=0 / license_duration=0（无有效授权额度）。 即状态从"能用"变成了"只发广告"（此前同一身份能拿到 txog.ktvsky.com / download.origjoy.com 的真源）。 我们拒绝广告地址本身是**正确**的（否则就是 1.4.10 修过的"广告被当成歌曲播放"）， 所以用户看到的"全部失效"其实是"源站不再给真源 + 我们拒绝广告"的叠加结果。 修复（可操作化，避免用户只看到一句"无法生成下载地址"）: - SongUrlResolver 统计"全部源只返回不可信地址"这一形态，识别为授权窗口失效： · 打 SOURCE-BLOCKED 日志（含示例 url，便于远程取证）； · 调用 Eac19WindowGuard.noteRiskBlocked() → 弹「歌曲源临时受限」提示， 明确告知"额度记在出口 IP 上、换设备无效"，引导重启光猫/路由器更换公网 IP； · 进入 3 分钟冷却(BLOCKED_COOLDOWN_MS)：期间快速失败，避免继续冲击源站把限流拖更久； 拿到真源立即解除冷却。 - AdVideoFilter 的广告特征补上 wb66 / demo（与 JS 的 isDemoUrl 对齐，两条取址路径判定一致）。 - 提示文案补充"或对每首歌只返回广告/测试资源"这一新表现。 - 新增回归测试：用实测 URL https://wb66.cn/f/d/7b7c9/10188555.ts 锁住拦截行为。 - Eac19WindowGuard 文档补充两种受限形态。 现场恢复办法：更换公网出口 IP（重启光猫/路由器重拨）。已下载歌曲不受影响，可正常播放。 版本 1.5.1(33) → 1.5.2(34)；签名证书不变。测试 9 例全通过。

Project Notice
This repository: https://gitea.kasugano.cn/zijunchiang/maidong-ktv
UI/feature framework credit: https://gitee.com/yangyachao-X/maidong-ktv
This repository reworks the upstream "Maidong KTV" UI and feature framework, and the core/data layer was rewritten with DSH (DeepSeek Harness): library sync, song-source integration, device auth, risk-control handling, remote logging, and ad blocking are all new implementations.
Highlights of the reworked data layer:
- Library: synced exclusively from the official Muse service
(
mconn.cherryonline.cnmls-api/v1/sqlite/sync); the code host carries source only, no database files. - Song source:
w.w345.my(i.phptoken →do.phpplayback URL) with fixed device identity and reproduced signing; ad/mismatched resources (e.g.wb66.cn/.../719.ts) are blocked and retried. - JS hot-update:
app/src/main/assets/mobile/ktv_api.js, requires theKTV_BRIDGE_API: 7marker.
Building
Requirements: JDK 17, Android SDK (compileSdk 35, minSdk 21, targetSdk 25),
Gradle wrapper 8.13 (bundled).
cd maidong-ktv
export JAVA_HOME=/path/to/jdk-17
export ANDROID_HOME=/path/to/android-sdk
export ANDROID_SDK_ROOT=$ANDROID_HOME
./gradlew assembleRelease
The release signing config in app/build.gradle expects ../../ktv_keystore.jks (one level above the
repo root) with alias ktv / password 123456; adjust paths or use signingConfigs.debug for a
quick unsigned build. Output: app/build/outputs/apk/release/app-release.apk
(dual ABI: armeabi-v7a + arm64-v8a). Install with adb install -r <apk>.
