From 424c3201833b9a4ce9c2e769482ec03bb5bb4d15 Mon Sep 17 00:00:00 2001 From: yml2213 Date: Sat, 12 Sep 2026 14:12:11 +0800 Subject: [PATCH] =?UTF-8?q?feat(pdd):=20=E5=8E=9F=E7=94=9F=E5=86=85?= =?UTF-8?q?=E5=B5=8C=E6=8B=BC=E5=A4=9A=E5=A4=9A=E5=A4=9A=E5=BA=97=E9=93=BA?= =?UTF-8?q?=E8=AE=A2=E5=8D=95=E5=90=8C=E6=AD=A5=E5=AD=90=E6=9C=8D=E5=8A=A1?= =?UTF-8?q?=E4=B8=8Eanti-content=E7=BA=AF=E7=AE=97=E5=BC=95=E6=93=8E?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 1. 纯算引擎 (pdd-anti-content.ts): - 100% 纯 TypeScript 原生还原 0as anti-content 算法，零 npm 依赖（仅基于 Node.js 原生 zlib 与 crypto）。 - 包含 22 个环境特征 Tag TLV 组包、zlib 标准压缩、4 字节尾部扰动盐与 64 字符动态位移 Base64 编码，单次耗时 < 0.1ms。 2. MMS 接口客户端与数据映射 (pdd-client.ts, pdd-order-mapper.ts): - 基于原生 fetch 实现高可用 MMS 请求，支持拼多多网关毫秒级服务器时间校准 (/api/server/_stm)。 - 实现拼多多订单状态与字段规范映射为平台 SourceOrderEvent，精准保留买家留言与充值账号信息。 3. 多店铺配置与防风控错峰调度 (pdd-source-config-service.ts, pdd-sync-service.ts): - 支持多店铺账号配置持久化（PostgreSQL app_config_entries 与本地 JSON 双模兜底）。 - 实现店铺间轻量错峰拉取机制，避免并发峰值触发平台 40002 频控。 4. 内存级自动进单与派单流转: - 拉取新订单后在 Node.js 内存中直接调用 upsertOrderFromSource()，自动完成 orders/order_items 入库、商品规则匹配与打手大厅工单 (work_orders) 实时广播。 5. 调度器与管理端 API (scheduler-service.ts, platform-config/pdd.ts): - 注册 pdd_order_sync 定时任务（默认 20s 轮询），提供管理端店铺配置查看、保存、删除及手动立即同步接口。 - 所有新增代码均遵循中英双语注释规范，并通过类型检查与单元测试。 --- apps/backend/data/pdd-source.example.json | 13 + apps/backend/src/config/app-config-keys.ts | 1 + .../src/routes/admin/platform-config.ts | 2 + .../src/routes/admin/platform-config/pdd.ts | 140 ++++++++ .../src/services/order/order-service.ts | 2 +- .../src/services/platforms/pdd/index.ts | 10 + .../platforms/pdd/pdd-anti-content.test.ts | 52 +++ .../platforms/pdd/pdd-anti-content.ts | 318 ++++++++++++++++++ .../src/services/platforms/pdd/pdd-client.ts | 222 ++++++++++++ .../platforms/pdd/pdd-order-mapper.test.ts | 75 +++++ .../platforms/pdd/pdd-order-mapper.ts | 132 ++++++++ .../pdd/pdd-source-config-service.ts | 187 ++++++++++ .../platforms/pdd/pdd-sync-service.ts | 196 +++++++++++ .../src/services/scheduler/config-service.ts | 43 +++ .../services/scheduler/pdd-order-sync-job.ts | 55 +++ .../services/scheduler/scheduler-service.ts | 6 +- 16 files changed, 1452 insertions(+), 2 deletions(-) create mode 100644 apps/backend/data/pdd-source.example.json create mode 100644 apps/backend/src/routes/admin/platform-config/pdd.ts create mode 100644 apps/backend/src/services/platforms/pdd/index.ts create mode 100644 apps/backend/src/services/platforms/pdd/pdd-anti-content.test.ts create mode 100644 apps/backend/src/services/platforms/pdd/pdd-anti-content.ts create mode 100644 apps/backend/src/services/platforms/pdd/pdd-client.ts create mode 100644 apps/backend/src/services/platforms/pdd/pdd-order-mapper.test.ts create mode 100644 apps/backend/src/services/platforms/pdd/pdd-order-mapper.ts create mode 100644 apps/backend/src/services/platforms/pdd/pdd-source-config-service.ts create mode 100644 apps/backend/src/services/platforms/pdd/pdd-sync-service.ts create mode 100644 apps/backend/src/services/scheduler/pdd-order-sync-job.ts diff --git a/apps/backend/data/pdd-source.example.json b/apps/backend/data/pdd-source.example.json new file mode 100644 index 00000000..5ce19c95 --- /dev/null +++ b/apps/backend/data/pdd-source.example.json @@ -0,0 +1,13 @@ +{ + "enabled": true, + "pollIntervalSeconds": 20, + "stores": [ + { + "shopId": "pdd_example_shop", + "shopName": "拼多多示例店铺", + "cookie": "api_uid=...;
