+# 飞驰 HTTP → GB/T 32960 桥接服务
+
+## 目标
+
+将飞驰车辆数据平台中的 20 辆 `GB_T32960` 车辆转换为 GB/T 32960.3-2016 标准 TCP 报文，并发送到岭牛内网车辆网关的 32960 端口。
+
+服务必须满足：
+
+- 每 10 秒发现实时增量，不重复转发平台持续返回的最后一帧；
+- 使用 `0x05` 完成平台登录，实时数据使用 `0x02`，历史补传使用 `0x03`；
+- 每帧收到内网网关成功 ACK 后才推进持久化游标；
+- 自动完成 CSRF 初始化、验证码识别、RSA 密码登录和 `R_SESS` 会话维护；
+- 源会话返回 401/403 时自动重新登录，并重放一次原 API 请求；
+- TCP 断线后重新登录，并用相同原始帧重试一次；
+- 重启后从本地游标继续，默认补齐最近 1 小时、每次查询 20 分钟；
+- 保留源接口调用、目标 ACK、错误和活跃车辆等 Prometheus 指标；
+- 不转发离线车辆反复返回的旧快照。
+- 离线车辆最后快照按源时间仅补发一次 `0x03`，不伪装成实时 `0x02`。
+
+## 数据路径
+
+```text
+飞驰 HTTP API
+  ├─ 车辆发现 vehicleRealStatuss
+  ├─ 实时明细 vehicleRealStatussByVId
+  └─ 历史明细 hisdataQuerys
+          │

+  字段映射 → 去重 → 32960 编码 → ACK 后提交游标
+          │
+          ▼
+内网 vehicle-gateway :32960
+```
+
+桥接服务当前编码 V2016 `##` 报文。源平台确认的主要字段如下：
+
+| 32960 数据 | 飞驰字段 |
+|---|---|
+| 数据时间 | `2000`（兼容 `9999`） |
+| 车速、里程、挡位 | `2201`、`2202`、`2203` |
+| 加速/制动踏板 | `2208`、`2209` |
+| 运行模式、DCDC | `2213`、`2214` |
+| 充电状态、车辆状态 | `2301`、`3201` |
+| 总电压、总电流、绝缘电阻 | `2613`、`2614`、`2617` |
+| SOC | `7615` |
+| 原始经纬度 | `2502`、`2503` |
+| 单体电压、温度 | `2003`、`2103` |
+| 极值 | `2601`—`2612` |
+| 燃料电池主要数据 | `2110`—`2121` |
+| 驱动电机复合数据 | `2307`、`2308` |
+
+定位必须使用 `2502/2503` 原始坐标；`.gd` 字段是页面地图转换坐标，不能写进国标数据。
+
+## 自动登录与认证文件
+
+服务按照网页端协议执行 `first-login → randCode → login`：读取 `x-api-csrf`/`CSRF`，验证码图片交给 ECS 本机、禁网运行的专用 OCR 容器，密码使用网页端同一 RSA 公钥做 PKCS#1 v1.5 加密，登录成功后保存响应中的 `R_SESS`。OCR 结果不会被直接信任；登录接口是最终校验，错误时会换一张验证码重试。密码、Cookie、验证码图片和响应正文均不写日志。
+
+`/opt/lingniu-go-native/secrets/feichi-auth.json`：
+
+```json
+{
+  "username": "replace-me",
+  "password": "replace-me"
+}
+```
+
+文件权限必须为 `0600`。飞驰若提供机器账号、长期 Token 或正式接口鉴权，仍应优先切换到供应商承诺的方式。
+
+`/opt/lingniu-go-native/secrets/feichi-target.json`：
+
+```json
+{
+  "platformId": "FEICHIBRIDGE00001",
+  "username": "bridge",
+  "password": "replace-me"
+}
+```
+
+`platformId` 必须正好 17 字节。目标网关启用 `GB32960_AUTH_MODE=enforce` 时，需在网关凭据文件中登记同一平台账号和密码。
+
+## 环境配置
+
+`/opt/lingniu-go-native/env/feichi-bridge.env` 最小配置：
+
+```dotenv
+FEICHI_BASE_URL=http://mob.fsfeichi.com.cn:8000
+FEICHI_AUTH_SECRET_FILE=/opt/lingniu-go-native/secrets/feichi-auth.json
+FEICHI_TARGET_SECRET_FILE=/opt/lingniu-go-native/secrets/feichi-target.json
+FEICHI_TARGET_ADDR=127.0.0.1:32960
+FEICHI_STATE_FILE=/var/lib/lingniu-feichi-bridge/state.json
+HEALTH_ADDR=127.0.0.1:20219
+```
+
+可调参数及默认值：
+
+| 参数 | 默认值 | 说明 |
+|---|---:|---|
+| `FEICHI_POLL_INTERVAL_SECONDS` | 10 | 实时轮询间隔 |
+| `FEICHI_DISCOVERY_INTERVAL_SECONDS` | 300 | 车辆清单刷新间隔 |
+| `FEICHI_FETCH_CONCURRENCY` | 4 | 明细接口并发数 |
+| `FEICHI_SOURCE_STALE_SECONDS` | 120 | 超过该时间不作为实时帧转发 |
+| `FEICHI_STALE_REISSUE_ENABLED` | true | 将离线旧快照去重后仅补发一次为 `0x03` |
+| `FEICHI_HTTP_TIMEOUT_SECONDS` | 15 | HTTP 超时 |
+| `FEICHI_OCR_IMAGE` | `lingniu/feichi-captcha-ocr:1.0.0` | 本机验证码 OCR 镜像 |
+| `FEICHI_OCR_TIMEOUT_SECONDS` | 20 | 单次验证码识别超时 |
+| `FEICHI_LOGIN_MAX_ATTEMPTS` | 20 | 单轮自动登录最多验证码次数 |
+| `FEICHI_LOGIN_RETRY_SECONDS` | 1 | 验证码/登录失败重试间隔 |
+| `FEICHI_TARGET_TIMEOUT_SECONDS` | 10 | TCP 写入和 ACK 超时 |
+| `FEICHI_BACKFILL_ENABLED` | true | 是否启用历史补传 |
+| `FEICHI_BACKFILL_LOOKBACK_SECONDS` | 3600 | 无游标时回看范围 |
+| `FEICHI_BACKFILL_WINDOW_SECONDS` | 1200 | 单次历史查询窗口 |
+| `FEICHI_BACKFILL_SAFETY_SECONDS` | 30 | 历史与实时之间的安全延迟 |
+| `FEICHI_BACKFILL_INTERVAL_SECONDS` | 3600 | 补传巡检周期 |
+
+飞驰地址当前是明文 HTTP。部署时应限制服务的出口目的地址，并避免认证文件、Cookie、响应原文进入代理访问日志。
+
+## 构建与启动
+
+```bash
+cd go/vehicle-gateway
+go test ./internal/feichibridge ./cmd/feichi-bridge
+CGO_ENABLED=0 go build -trimpath -o feichi-bridge ./cmd/feichi-bridge
+
+docker build -t lingniu/feichi-captcha-ocr:1.0.0 ../../deploy/feichi-ocr
+install -d -m 0750 /var/lib/lingniu-feichi-bridge
+systemctl daemon-reload
+systemctl enable --now lingniu-go-feichi-bridge
+```
+
+检查：
+
+```bash
+curl -fsS http://127.0.0.1:20219/healthz
+curl -fsS http://127.0.0.1:20219/readyz
+curl -fsS http://127.0.0.1:20219/metrics | grep vehicle_feichi_bridge
+journalctl -u lingniu-go-feichi-bridge -f
+jq '.vehicles | to_entries[] | select(.value.last_realtime_ack_at or .value.last_backfill_ack_at) |
+    {vin: .key, realtime_ack: .value.last_realtime_ack_at, backfill_ack: .value.last_backfill_ack_at}' \
+    /var/lib/lingniu-feichi-bridge/state.json
+```
+
+## 上线验收
+
+先选 1 辆在线车灰度 30 分钟，再开放全部 20 辆。验收需要同时满足：
+
+1. 网关收到一次 `0x05` 登录，后续实时帧为 `0x02`；
+2. 同一源时间和同一内容只落一条，重启后无持续重复；
+3. 断开目标 TCP 后能重连、重新登录并继续收到 ACK；
+4. 使源会话过期后能自动重登；连续登录失败时 `/readyz` 变为 503，游标不前移；
+5. 两辆离线车不会把历史最后一帧当实时数据周期发送；
+6. 原始经纬度、总压、总流、SOC、单体电压和温度与平台页面抽样一致；
+7. 20 辆车连续运行 24 小时后，源/目标计数和平台记录数差异可解释。
+
+## 已知边界
+
+- 页面接口不是飞驰承诺的稳定开放 API，接口结构升级可能要求同步调整客户端；
+- 验证码识别依赖本机 OCR 镜像和飞驰当前验证码样式；样式变化会触发登录失败告警，不会导致未 ACK 数据推进游标；
+- 源接口只提供离散快照，无法恢复平台未保存或查询窗口之外的原始上行帧；
+- 映射结果是标准 32960 语义报文，不是车辆原始二进制报文的逐字节复制。

 stat-writer 默认 `STATS_WORKERS=3`，每个 worker 是同一 consumer group 的独立 Kafka reader。Kafka 按车辆 key 固定分区，因此单车累计里程仍按分区顺序执行，不同分区并行。调整 worker 后同时核对 `vehicle_stat_config{setting="workers"}`、每个 `vehicle_stat_worker_active{worker}`、MySQL 连接数、write p99 和 stat lag；worker 不应超过 fields topic 的有效分区并行度。

+stat-writer 对死锁、锁等待和网络中断等瞬时 MySQL 故障按 `STATS_RETRY_ATTEMPTS` 有限重试，重试耗尽后保持失败关闭并等待存储恢复。只有 `NULL`、数值越界、类型转换、字段过长和 CHECK 约束这类明确的单消息数据错误，才会在同样的有限重试耗尽后写入 `STATS_QUARANTINE_DIR` 并提交该 Kafka 偏移量，避免一条坏消息阻塞整个分区；表结构、权限和未知程序错误不会被隔离。隔离文件包含原 topic、partition、offset、key、value 和错误，默认权限为 `0600`，处理前不得删除。
+
 history-writer 和 realtime-writer 同样默认分别使用 `HISTORY_WORKERS=3`、`REALTIME_WORKERS=3`。每个 worker 只顺序处理 Kafka 分配给自己的分区，TDengine 表缓存、MySQL 实时节流缓存和车牌缓存均支持并发访问。调整后必须同时核对对应的 `*_config{setting="workers"}`、`*_worker_active`、pending/retry、后端连接数和 Kafka lag。

 history-writer 启动会对既有 `vehicle_locations` stable 幂等补齐 `soc_percent DOUBLE`。发布后除 `/readyz` 外，必须抽查一台支持 SOC 的车辆在 TDengine 历史位置中 `soc_percent IS NOT NULL`；如果迁移报错且不是明确的重复列错误，服务应保持未就绪，先处理 TDengine DDL/权限，不能跳过迁移后强启。
