为什么不能"秒学完"——平台源码级证据
我把播放器主包（spring-grain）反混淆后拿到了它自己的计时与上报代码，结论是确定的：
| 机制 | 平台实现 | 后果 |
|---|
| 计时器 | setInterval(fn,1000) 里 durationTime++ | 按真实墙上时钟累计，与视频播放位置无关 |
| 上报 | 每 25 秒 POST /heartbeat-center/hb/report，watchTime:25 | watchTime 是写死的常量，不是视频进度 |
| 时长要求 | courseCompleteTimeRate:100 | 每门课必须看满 100% 时长 |
| 进度条 | boolDragLock:1 | 禁止拖动，跳片尾无效 |
| 防挂机 | boolFoolproofLock:2 · foolproofDuration:1800 | 挂机检测 |
| 弹题 | openTestPercentage:60 | 60% 处弹验证题，需本人作答 |
| 多端互斥 | boolMultiClientOpen:2（错误码 3028002） | 同一账号只能一个终端学 |
1. 倍速不会更快拿到学时。上报的是墙上时钟，2 倍速只让视频提前播完，学时仍按真实秒数记——一门 60 分钟的课，2 倍速 30 分钟播完，你只拿到约 30 分钟，剩下白丢。所以助手锁死 1 倍速，这是数学上的最优解。
2. 唯一能"秒学完"的办法是绕过播放器直接伪造 25 秒一次的 hb/report 请求刷学时。那是伪造学习记录，结果会进你的继续教育学分，一旦核查是实打实的问题——所以助手不做。
3. 现实结论：1440 分钟 = 24 小时真实时间，这个下限压不掉。助手能把"你必须坐在电脑前"的 24 小时，压成"只需在平台强制本人确认时点一下"。

装好油猴Chrome / Edge 装 Tampermonkey（篡改猴）；360 极速浏览器在扩展中心搜 Tampermonkey。装完工具栏会出现黑色方块图标。
安装本脚本把 研修网学习助手.user.js 拖进浏览器窗口，油猴弹出安装页，点「安装」。
登录研修网在要挂机的电脑上登录，然后打开「学习空间」页面（网址含 /train2/workspace/）。右下角出现蓝色「研」按钮即成功。
点「研」→ 自动挂机 → 生成队列 → 开始推荐「最短达标」：按时长从短到长排好，用最少的课凑满 ${REQUIRE_MIN} 分钟。点「开始自动看课」，第一门课自动打开。
然后去干别的播放页自动：静音 → 播放 → 播完自动下一节 → 本门播完自动下一门 → 队列跑完自动停。播放页意外关闭时，学习空间页的「看门狗」会自动重开。
面板怎么用
两个面板都能拖动（按住顶部彩色标题栏）和缩放（拖右下角斜纹），位置大小会自动记住。
播放页面板显示：课程名 / 讲师 / 本节序号 / 本节标题 / 本节时长 / 全章节列表（含每节时长和"本机已播完"标记）；点章节右侧「播」可直接跳过去。
必须知道的三件事
1. 别关播放页标签页。可以切到别的窗口、别的标签页；开了「后台保活」浏览器不会冻结它。学习空间页也留着，看门狗靠它重开播放页。
2. 平台会弹「回答问题完成验证」和「继续计时」。这是研修网的防挂机机制。助手会响铃 + 桌面通知 + 把窗口拉到前台提醒你，但不替你作答、也不替你点「继续」——你处理完，自动连播自己继续。
3. 学时按真实时长累计，倍速会少记，所以助手固定 1 倍速；进度条受平台锁定，不可拖动。
常见问题
Q：面板读不到章节标题和时长？点面板右上角 ⟳ 刷新课程数据；仍不行就点「自检」把信息发到反馈群。
Q：切出去回来发现停了？多半是弹验证题，面板会变红提示，答完自动继续。
Q：能开两个播放页吗？不能，平台限制单端（错误码 3028002），助手会自动暂停第二个。
Q：看板数据准吗？来自研修网官方接口，与学习空间一致。

为什么不能"秒学"——真实抓包证据
我用浏览器抓到了平台自己发出的心跳请求，规则是确定的，不是猜的：
| 字段 | 实测值 | 含义 |
|---|
| 端点 | POST /heartbeat-center/hb/report | 每 ~25 秒一次 |
| watchTime | 25（写死） | 每次固定 +25 秒，不是视频进度 |
| watchLocation | 累计 +25 / 次 | 累计观看位置，到时长即本节完成 |
| 响应 | {"code":200,"data":"success"} | 服务端按收到次数累计学时 |
① 倍速不会更快，反而少记。学时 = 心跳次数 × 25 秒（真实墙上时钟）。2 倍速只让视频提前播完、心跳次数变少 → 你拿到的学时更少。所以助手锁死 1 倍速。
② 唯一能"秒学完"的办法是伪造 25 秒一次的心跳刷学时，那是伪造学习记录、会进你的继续教育学分，核查是实打实的风险——本项目底线明确不做。
③ 真正最快的合规路径：1x 真实观看 + 无缝自动连播（本门播完自动下一节/下一门）+ 后台保活（离开也跑）+ 断点续播（跳过已看）。下面四项全开就拉满：

装好油猴Chrome / Edge 装 Tampermonkey（篡改猴）；360 极速浏览器在扩展中心搜 Tampermonkey。
安装本脚本把 研修网学习助手.user.js 拖进浏览器窗口 → 油猴弹窗点「安装」。
登录研修网并打开学习空间网址含 /train2/workspace/，右下角出现蓝色「研」按钮即生效。
自动挂机 → 生成队列 → 开始选「最短达标」可用最少门数凑满 ${REQUIRE_MIN} 分钟。点开始后自动打开第一门课。
去干别的播放页自动静音、自动下一节、本门完自动下一门。两个面板都能拖动和缩放。
必须知道的三件事
1. 别关播放页标签页；切到其他窗口没关系，开了「后台保活」就不会被浏览器冻结。学习空间页也要留着——看门狗靠它重开播放页。
2. 平台在约 60% 处会弹「回答问题完成验证」，长时间无操作还会弹「继续计时」，这是防挂机机制。助手会响铃 + 桌面通知 + 把窗口拉到前台，但不替你作答、也不替你点「继续」。
3. 学时按真实时长累计，倍速会少记，所以固定 1 倍速；进度条被平台锁定，不可拖动。
常见问题
Q：面板读不到章节标题和时长？点面板右上角 ⟳ 刷新课程数据；仍不行就点「自检」把信息发到反馈群。
Q：切出去回来发现停了？多半是弹验证题，面板会变红提示，答完自动继续。
Q：能开两个播放页吗？不能，平台限制单端（错误码 3028002），助手会自动暂停第二个。
Q：数据准吗？来自研修网官方接口，与学习空间一致。
