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",[192],"pulls","branches",1,"forks","envVars",{"_206":181,"_208":61},"connections",{"_206":61,"_207":61},"count","unfilledCount","emptyCount",{"_43":191,"_32":192,"_30":193,"_139":-5,"_41":42,"_40":194,"_141":25,"_38":239,"_13":162,"_33":20,"_35":196,"_24":25,"_146":-5,"_218":240,"_27":241},{"_43":184,"_32":185,"_30":186,"_139":-5,"_41":42,"_40":187,"_141":25,"_38":236,"_13":143,"_33":34,"_35":189,"_24":25,"_146":-5,"_218":237,"_27":238},{"_43":176,"_32":177,"_30":178,"_139":-5,"_41":42,"_40":179,"_141":25,"_38":233,"_13":181,"_33":34,"_35":182,"_24":25,"_146":-5,"_218":234,"_27":235},{"_43":169,"_32":170,"_30":171,"_139":-5,"_41":42,"_40":172,"_141":25,"_38":230,"_13":162,"_33":34,"_35":174,"_24":25,"_146":-5,"_218":231,"_27":232},{"_43":165,"_32":28,"_30":31,"_139":-5,"_41":42,"_40":14,"_141":25,"_38":227,"_13":167,"_33":34,"_35":37,"_24":25,"_146":-5,"_218":228,"_27":229},{"_43":157,"_32":158,"_30":159,"_139":-5,"_41":42,"_40":160,"_141":25,"_38":224,"_13":162,"_33":34,"_35":163,"_24":25,"_146":-5,"_218":225,"_27":226},{"_43":148,"_32":149,"_30":150,"_139":-5,"_41":42,"_40":151,"_141":25,"_38":221,"_13":153,"_33":154,"_35":155,"_24":25,"_146":-5,"_218":222,"_27":223},{"_43":136,"_32":137,"_30":138,"_139":-5,"_41":42,"_40":140,"_141":25,"_38":217,"_13":143,"_33":144,"_35":145,"_24":25,"_146":-5,"_218":219,"_27":220},["D",1785774681505],"children",[],[137],["D",1785774789725],[],[149],["D",1785774664221],[],[158],["D",1786550432167],[],[28],["D",1785774645387],[],[170],["D",1786550432084],[],[177],["D",1786550431976],[],[185],["D",1786549724118],[],[192],["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":280,"_281":282,"_283":284,"_285":25,"_286":25,"_287":25,"_288":123,"_289":-5,"_290":-7,"_291":-7,"_292":61,"_293":25,"_294":25,"_295":-5,"_296":25,"_297":25,"_298":25,"_299":-5},"ENV",{"_251":252,"_253":254,"_255":88,"_256":257,"_258":259,"_260":261,"_262":263,"_264":265,"_266":267,"_268":269,"_270":271,"_272":273,"_274":275,"_276":277,"_278":279},"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"]
