Town](https://www.val.town) 的 Deno\n运行时上。按关键词规则监控「好价」列表，命中后以富文本卡片推送到 Telegram。\n\n这是对 `yuxiaoy/smzdm` 的重构版本：存储从单个 blob JSON 换成 SQLite，抓取从固定\n5 页换成增量游标翻页，推送从纯文本 `标题: 链接`\n换成带价格/商城/热度/爆料原文/按钮的卡片。\n\n## 文件结构\n\n| 文件 | 类型 | 作用 |\n| ------------ | ------------ | --------------------------------------------------- |\n| `shared.ts` | script | 环境变量、可调参数、时间与价格解析等纯函数 |\n| `db.ts` | script | SQLite 表结构、设置存取、推送历史、旧 blob 数据迁移 |\n| `smzdm.ts` | script | 好价接口客户端与增量游标翻页 |\n| `matcher.ts` | script | 规则解析与匹配 |\n| `notify.ts` | script | Telegram 卡片渲染、限流、重试 |\n| `spider.ts` | **interval** | 定时任务入口 |\n| `webhook.ts` | **http** | Telegram 命令入口 |\n\n## 部署\n\n1. 在 Val Town 新建一个 val，把上面 7 个文件贴进去，注意把 `spider.ts`\n 的类型设为 **Interval**、`webhook.ts` 设为 **HTTP**，其余保持 Script。\n2. 配置环境变量（Settings → Environment Variables）：\n\n | 变量 | 必填 | 说明 |\n | ---------------- | ---- | ----------------------------------------------------------------------- |\n | `BOT_TOKEN` | 是 | @BotFather 给的 bot token |\n | `CHAT_ID` | 是 | 接收推送的 chat id |\n | `OWNER_IDS` | 建议 | 允许发命令的 Telegram 用户 id，逗号分隔。**留空时机器人会拒绝所有命令** |\n | `WEBHOOK_SECRET` | 否 | webhook 校验密钥，不填则由 token 派生 SHA-256 |\n\n3. 用浏览器打开 `webhook.ts` 的 HTTP 地址一次。GET 请求会注册 webhook\n 和命令菜单，并返回注册结果。之后每次改动 URL 都要再访问一次。\n4. 把 `spider.ts` 的 interval 设为 **10 分钟**。增量翻页在闲时只发 1 个请求，\n 忙时自动加深，所以跑得勤反而更省也更及时。\n5. 在 Telegram 里 `/add_brands 你的关键词` 开始用。\n\n`OWNER_IDS` 如果不填，任何人找到这个 bot 都会被拒绝命令——这是故意的安全默认值。\n你的用户 id 可以问 [@userinfobot](https://t.me/userinfobot)。\n\n## 规则语法\n\n一条规则是不含空格的单个 token，内部用 `-` 分隔多个条件：\n\n| 写法 | 含义 |\n| --------------------------- | ----------------------------- |\n| `apple` | 含 `apple` |\n| `apple-watch` | 同时含 `apple` 和 `watch` |\n| `sony\\|索尼-耳机` | （`sony` 或 `索尼`）且 `耳机` |\n| `apple-watch-!表带-!钢化膜` | 排除配件噪音 |\n| `nike-<300` | 价格不超过 300 |\n| `茅台->1000` | 价格不低于 1000 |\n| `/rtx\\s?40[6-9]0/` | 正则，忽略大小写 |\n| `!/翻新\\|拆机/` | 负向正则 |\n\n约束：\n\n- `-` 是分隔符，所以品牌名里带连字符的要写成正则。\n- 只有排除条件、没有正向条件的规则会被 `/add_brands`\n 拒绝，否则它会命中全站好价。\n- 价格解析不出来的（`包邮`、`1元起`）**不会**被价格条件挡掉，宁可多推不漏推。\n- 中文没有词边界，`米` 这种短词误报率很高，建议配合排除词或正则。\n\n用 `/test 商品标题 199元` 可以看每条规则命中与否以及原因。\n\n## 命令\n\n```\n/help 使用说明\n/brands 查看规则\n/add_brands a b 添加规则\n/delete_brands

Town 的出口 IP\n拿不到数据。`api.smzdm.com/v1/youhui/list` 是开放 JSON，这个端点不需要鉴权。\n\n**为什么用 `article_date` 而不是 `article_unix_date` 排序。**\n两个字段实测对不上：同一条 `article_date` 为 `00:06:41` 的商品，其\n`article_unix_date` 换算出来差了约 12 小时；两条相隔 7 秒的商品 unix 值差了 25\n分钟。所以时间排序和游标都基于 `article_date`（东八区）。\n\n**为什么改成增量翻页。** 实测好价流 80 条只跨约 35 分钟，且存在 7\n秒一条的爆发。固定抓 100 条约等于 44\n分钟的流量，白天高峰期会静默漏掉中间的商品。现在的做法是逐页往下翻，\n直到某一页不再包含比游标更新的条目为止，上限 20 页。\n\n判断「是否继续翻页」用的是「本页有几条比游标新」，而不是「本页最旧一条的时间」——因为\n`offset=0` 会出现运营置顶的老帖（实测见到 2021\n年的），用最旧时间判断会在第一页就误停。翻页步进取\n`min(PAGE_SIZE, 实际返回条数)`，保证宁可重叠也不跳过，因为接口并不严格遵守\n`limit`。\n\n**为什么过滤 `article_is_timeout` / `article_is_sold_out`。**\n列表里混有已失效和已售罄的条目，`offset=0`\n第一条就可能是几年前的置顶好价。不过滤就会推送早已过期的「好价」。\n\n**为什么先发送后入库。** 只有 Telegram 确认送达才写入\n`smzdm_deals_v1`；发送失败的条目\n会把游标回退到它之前，下一轮重试。旧版本是先入库再发送且忽略发送错误，一旦被限流，\n那条商品就永久丢失了。\n\n**为什么用 SQLite 而不是 blob。** `article_id` 做主键让去重精确且\nO(1)；每行带时间戳让历史按 30 天滚动过期，而不是像旧版那样攒到 150\n条就整表清空——清空后所有仍在列表里的旧商品会被当成新的重推一遍。SQLite\n也不存在两次 `setJSON` 互相覆盖的丢更新问题。\n\n## 本地测试\n\n测试放在 `tests/`，不需要 Val Town 账号，也不会碰到线上数据库或真实 Telegram：\n`fetch` 全程被桩替换，`std/sqlite` 和 `std/blob` 通过 `tests/import_map.json`\n指向内存里的假实现。`.vtignore` 会让 `vt push` 跳过整个 `tests/` 目录。\n\n```bash\n# 全部 78 个用例（含真实接口的集成测试）\nBOT_TOKEN=x:y CHAT_ID=1 OWNER_IDS=42 deno test --no-prompt --allow-env \\\n --allow-net --allow-read --allow-import \\\n --import-map=tests/import_map.json tests/\n\n# 离线时跳过联网用例\nSKIP_LIVE=1 BOT_TOKEN=x:y CHAT_ID=1 OWNER_IDS=42 deno test --no-prompt \\\n --allow-env --allow-read --allow-import \\\n --import-map=tests/import_map.json tests/\n\ndeno check --allow-import *.ts\ndeno lint .\n```\n\n三个环境变量都是占位符。`shared.ts` 在导入时会校验 `BOT_TOKEN` 和 `CHAT_ID`\n存在， `OWNER_IDS=42` 是 `webhook_test.ts` 里那个「机主」的 id。\n\n| 文件 | 覆盖内容 |\n| ----------------- | ----------------------------------------------------------------------- |\n| `pure_test.ts` | 价格与日期解析、静音时段、分块、规则 DSL 全部语法 |\n| `notify_test.ts` | 卡片字段、HTML 转义、实体截断、429 重试、400 降级、摘要分块 |\n| `sql_test.ts` | 从 `db.ts` 抽出 SQL 丢给真实 SQLite 校验，并验证降价 upsert 语义 |\n| `spider_test.ts` | 完整链路：过滤、去重、溢出摘要、失败重试、降价复推、失败告警、blob 迁移 |\n| `webhook_test.ts` | 密钥校验、机主白名单、命令与参数校验、回调按钮、GET 注册 |\n| `live_test.ts` | 真实接口：字段契约、游标翻页、时间戳异常、抓取速率 |\n\n写测试时踩到的两个坑，改测试代码前值得知道：grammY 靠 `bot_command` entity\n识别命令，伪造的 update 必须带上；它还在调用时才从 `globalThis` 取\n`fetch`，所以 `webhook_test.ts` 的桩要常驻，并对非 Telegram 请求透传。\n\n`live_test.ts` 里有两个断言是「设计前提的哨兵」：如果 SMZDM 修好了\n`article_unix_date`，或者不再往列表里塞置顶老帖，它们会失败，提示对应的实现\n可以简化。\n\n## 从旧版本迁移\n\n首次运行时 `db.ts` 会自动把 blob 里的 `smzdm_brands` 读进\nSQLite，品牌列表不会丢。\n\n`smzdm_result` 里只有 `[标题, 链接]`，没有\n`article_id`，没法用来给去重表打底，所以会被\n忽略并打一条日志。为避免首轮重推，第一轮只抓 3 页，且默认只推 24\n小时内发布的好价。\n\n确认无误后可以自行删掉两个旧 blob key。\n\n## 已知取舍\n\n- `/min_worthy` 会挡掉刚发布的好价（票数为\n 0），而刚发布的往往是最值得抢的，所以默认 0。\n- `matchContent`\n 默认开启，覆盖更全（爆料原文常含具体型号），代价是误报略多，可关。\n- 单轮最多发 8 张卡片，多出来的合并成一条摘要，既不刷屏也不丢条目。\n- 同一商品最多推 3 次（首次 + 降价），防止价格反复波动时刷屏。\n",[191],"pulls","branches",1,"forks","envVars",{"_205":157,"_207":61},"connections",{"_205":61,"_206":61},"count","unfilledCount","emptyCount",{"_43":190,"_32":191,"_30":192,"_139":-5,"_41":42,"_40":193,"_141":25,"_38":238,"_13":173,"_33":20,"_35":195,"_24":25,"_146":-5,"_217":239,"_27":240},{"_43":183,"_32":184,"_30":185,"_139":-5,"_41":42,"_40":186,"_141":25,"_38":235,"_13":143,"_33":158,"_35":188,"_24":25,"_146":-5,"_217":236,"_27":237},{"_43":176,"_32":177,"_30":178,"_139":-5,"_41":42,"_40":179,"_141":25,"_38":232,"_13":157,"_33":158,"_35":181,"_24":25,"_146":-5,"_217":233,"_27":234},{"_43":168,"_32":169,"_30":170,"_139":-5,"_41":42,"_40":171,"_141":25,"_38":229,"_13":173,"_33":158,"_35":174,"_24":25,"_146":-5,"_217":230,"_27":231},{"_43":161,"_32":162,"_30":163,"_139":-5,"_41":42,"_40":164,"_141":25,"_38":226,"_13":150,"_33":158,"_35":166,"_24":25,"_146":-5,"_217":227,"_27":228},{"_43":152,"_32":153,"_30":154,"_139":-5,"_41":42,"_40":155,"_141":25,"_38":223,"_13":157,"_33":158,"_35":159,"_24":25,"_146":-5,"_217":224,"_27":225},{"_43":148,"_32":28,"_30":31,"_139":-5,"_41":42,"_40":14,"_141":25,"_38":220,"_13":150,"_33":34,"_35":37,"_24":25,"_146":-5,"_217":221,"_27":222},{"_43":136,"_32":137,"_30":138,"_139":-5,"_41":42,"_40":140,"_141":25,"_38":216,"_13":143,"_33":144,"_35":145,"_24":25,"_146":-5,"_217":218,"_27":219},["D",1785774681505],"children",[],[137],["D",1786550432446],[],[28],["D",1786550432255],[],[153],["D",1786550432167],[],[162],["D",1785774645387],[],[169],["D",1786550432084],[],[177],["D",1786550431976],[],[184],["D",1786549724118],[],[191],["D",1779893066929],["D",1789494036282],{"_98":97,"_105":101},{"_98":97,"_99":-5,"_100":101,"_18":55,"_102":103,"_104":25},{"_13":87,"_32":88,"_43":42,"_89":44,"_90":-5,"_91":-5,"_92":-5,"_93":-5,"_94":-5,"_95":45,"_96":97},"ctx",{"_80":-5,"_125":279,"_280":281,"_282":283,"_284":25,"_285":25,"_286":25,"_287":123,"_288":-5,"_289":-7,"_290":-7,"_291":61,"_292":25,"_293":25,"_294":-5,"_295":25,"_296":25,"_297":25,"_298":-5},"ENV",{"_250":251,"_252":253,"_254":88,"_255":256,"_257":258,"_259":260,"_261":262,"_263":264,"_265":266,"_267":268,"_269":270,"_271":272,"_273":274,"_275":276,"_277":278},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","e87eb04e707cf64e7e532c8e8ec395f209e17f15","RENDER_GIT_BRANCH","POSTHOG_API_TOKEN","phc_nmoyuAkStEZuUp69rYlg1DZgrIt19Gx0Y4Hwf8tGgJP","POSTHOG_API_HOST","https://wart.val.town","WEB_API_TEMPLATE","https://{val}.web.val.run","APP_URL","https://www.val.town","MODULE_URL","https://esm.town","VANITY_WEB_API_TEMPLATE","https://{label}.val.run/","DENOLS_URL","https://lsp.val.town","NODE_ENV","production","CLOUDFLARE_TURNSTILE_SITE_KEY","0x4AAAAAACtaIZJH7s9rBMZ6","GOOGLE_CLIENT_ID","875989696899-jtsqkhlbdv5jrlsk8631p7ipjg3c6o62.apps.googleusercontent.com","STRIPE_PUBLISHABLE_KEY","pk_live_51N2zvWEpZTTLipIkVEwXrUG9AT0yeOOEYxszarZT1jpsZV58Ly6wlg3SltZpHN26CUalOBmUSY7adQRQiSkCZz2500qSXNkf8Y","API_URL","https://api.val.town",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
