ikuuu 全自动签到（Val Town 版）\n\n部署在 [Val Town](https://www.val.town) 上的 ikuuu\n每日自动签到：**邮箱+密码全自动登录**（GeeTest V4 交由 2Captcha\n求解），支持多账号、Cookie 复用、Telegram 通知。无需服务器，无需手动更新\nCookie。\n\n主脚本：[`main.ts`](./main.ts)\n\n## 为什么需要它\n\nikuuu 从 2026-04 起在登录页启用了 **GeeTest V4 验证码**，传统的\"邮箱+密码直接\nPOST 登录\"会返回：\n\n> 系统无法接受您的验证结果，请刷新页面后重试。\n\n本项目实测过纯算法求解器（GeekedTest 思路）与多家免费打码平台，在当前 GeeTest V4\n的 \"ai\" 类型题目上均已失效，因此改用 **2Captcha** 求解。配合下面的 Cookie\n复用策略，实际打码次数被压到极低，长期成本可忽略。\n\n## 工作原理\n\n```\nVal Town Cron\n └─ 读取 SQLite 中的账号状态（Cookie / 签到日期 / 失败计数）\n ├─ 今天已签到？ → 直接跳过，零请求零成本\n ├─ 有缓存 Cookie？ → 直接 POST /user/checkin\n └─ Cookie 失效？ → 2Captcha 求解 GeeTest V4 → POST /auth/login（phase=password） → 签到\n └─ 汇总结果，异常时推送 Telegram\n```\n\n关键点：**只有 Cookie 失效时才会打码**。ikuuu\n的会话通常能维持很久，所以绝大多数天数是零成本运行。\n\n## 部署步骤\n\n### 1. 创建 Val\n\n在 Val Town 新建一个 **Cron Val**，把 `main.ts` 的内容整体粘贴进去。\n\n建议 cron 设为每天一次，例如 `30 0 * * *`（UTC，对应北京时间 08:30）。\n\n### 2. 配置环境变量\n\n在 Val Town 的 **Settings → Environment Variables** 中添加。\n\n**必填：**\n\n| 变量 | 说明 |\n| ---------------- | ------------------------------------------------ |\n| `IKUUU_ACCOUNTS` | 账号列表，格式 `邮箱:密码`，多账号用 `\\|\\|` 分隔 |\n| `TWOCAPTCHA_KEY` | 2Captcha 的 API Key |\n\n多账号示例（Val Town 环境变量是单行，用 `||` 连接）：\n\n```\nalice@example.com:pwd1||bob@example.com:pwd2\n```\n\n> 按**第一个冒号**分隔邮箱和密码，所以密码含冒号没问题；但密码里不能出现 `||`。\n\n**可选：**\n\n| 变量 | 默认 | 说明 |\n| ------------------- | -------------------- | ----------------------------------------------------- |\n| `IKUUU_BASE_URL` | `https://ikuuu.org` | ikuuu 常换域名，失效时改这里 |\n| `IKUUU_CAPTCHA_ID` | 已内置 | GeeTest 验证码 ID，站点更新导致失效时才需覆盖 |\n| `TELEGRAM_TOKEN` | — | Telegram Bot Token（@BotFather 获取） |\n| `TELEGRAM_CHAT_ID` | — | 接收通知的 Chat ID（@userinfobot 获取） |\n| `ALWAYS_REPORT` | 关 | 设 `1` 则每次都推送回执，否则仅异常时推送 |\n| `FETCH_INFO` | 跟随 `ALWAYS_REPORT` | 设 `1` 则额外抓取剩余流量与到期日（每账号多一次请求） |\n| `BALANCE_ALERT` | `1` | 2Captcha 余额低于此值（美元）时告警 |\n| `FAIL_STREAK_ALERT` | `2` | 连续失败几次才升级为强提醒 |\n| `LOGIN_RETRIES` | `1` | 验证码被拒时的额外登录尝试次数 |\n| `CRED_PAUSE_AFTER` | `3` | 连续几次**凭据错误**后暂停打码（熔断） |\n| `MAX_SOLVES` | 账号数 ×(1+重试数) | 单次运行的打码硬上限 |\n| `CONCURRENCY` | `4` | 多账号并发数 |\n| `BUDGET_SEC` | `52` | 总时间预算，必须小于 Val Town 的运行上限 |\n| `HTTP_TIMEOUT_SEC` | `12` | 单个 HTTP 请求超时 |\n| `JITTER_MAX_SEC` | `5` | 每账号随机延迟上限，用于错峰 |\n| `TZ_OFFSET` | `8` | 判定\"今天\"所用的时区偏移 |\n| `FORCE` | 关 | 设 `1` 忽略\"今日已签\"缓存，强制执行 |\n| `RESET_STATE` | 关 | 设 `1` 清空失败计数与凭据熔断，跑完记得改回 |\n\n### 3. 手动跑一次验证\n\n在 Val Town 点 Run，看日志是否输出 `✅ 签到成功`。首次运行会打码登录并把 Cookie\n写入 SQLite，之后就走缓存了。\n\n## 设计要点\n\n**Cookie 优先，成本最低。** 签到本身不需要验证码，只有登录才需要。脚本把 Cookie\n持久化在 Val Town 的 SQLite 里，只在确认失效时才触发付费打码。\n\n**当天已签则完全跳过。** 成功签到会记录日期（按 `TZ_OFFSET`\n判定），同一天内重复运行不产生任何请求，手动重跑和 cron 重复触发都是安全的。\n\n**失败分类，避免误烧钱。** 5xx / 429 判定为服务端抖动并重试，不会误认成 Cookie\n失效而去登录；只有 301/302/401/403\n或响应内容像登录页才算失效。登录失败会区分\"验证码被拒\"（上报退款并重试）与\"凭据错误\"（不重试，直接告警）。\n\n**全局时间预算。** 每个网络请求前检查剩余时间，并始终预留 4 秒发送通知，避免被\nVal Town 静默掐断而收不到任何告警。\n\n**凭据熔断。**\n连续多次确凿的凭据错误后停止打码，避免密码改了却每天白烧钱。恢复方式：确认密码无误后加\n`RESET_STATE=1` 跑一次。\n\n## 常见问题\n\n**登录失败怎么排查？** 日志里会有一行\n`登录被拒(HTTP xxx) result=... 原文: ...`，那是服务端的真实回复。成功登录的标志是\n`result=authenticated`（不是旧版的 `ret=1`）。据此判断是域名变更、验证码配置变化还是账号问题。\n\n**为什么日志里曾出现 invalid_phase？** 2026-08 起登录 POST 必须带 `phase=password`、`host`、`pageLoadedAt` 和 GeeTest 字段；缺 `phase` 会被拒绝。当前 `main.ts` 已按这个格式提交。\n\n**ikuuu 换域名了？** 改 `IKUUU_BASE_URL` 即可。\n\n**成本大概多少？** GeeTest V4 在 2Captcha 约 $0.003/次。由于只在 Cookie\n失效时打码，实际一年下来通常不到 $1。\n\n**为什么不用 2Captcha 的 Browser API（云浏览器）？** 那是托管 Chrome 服务，需要\nPuppeteer/Playwright 通过 CDP 驱动。真实浏览器完成一次登录通常要几十秒，会超出\nVal Town 免费版 60 秒的运行上限——这正是本项目最初放弃 Puppeteer 方案的原因。当前\nHTTP 直连方案更快也更省。\n\n**安全吗？** 账号密码只存在 Val Town 环境变量中，不写入代码；日志不打印 Cookie\n与密码。\n\n## 目录结构\n\n```\n.\n├── main.ts # 主脚本（interval / cron）\n└── README.md\n```\n\n> 早期还有一套基于 GitHub Actions + 纯算法 GeeTest 求解器的实现（`checkin.py` /\n> `geeked/`），实测求解器已被 ikuuu
