Phase 1.3a。Phase 1.2 留的 repo 现在有了真正的业务出口,Phase 1.3b 紧接
handler / router 把 HTTP 接进来,业务就能跑通。
新增:
- pkg/decimal/money.go
* PricePerLiter(total, liters) 服务端实时算实际油价,落库
* ConsumptionL100km(l, mileage) 百公里油耗,只用于 is_full 序列
* CostPerKm(amount, mileage) 每公里成本
* Mileage(cur, prev) 行驶里程,负数 / 零视为无效
* AvgFloat64(xs) 求平均,空切片返回 0
全部走 shopspring/decimal,避免 float64 累计误差
- internal/dto/dto.go
* VehicleCreate / VehicleUpdate (patch 语义,*T 表示可选)
* RefuelCreate / RefuelUpdate
入参校验走 gin-validator 的 tag:required / gte / gt / max
(Liters > 0、TotalAmount >= 0、Odometer >= 0 与 plan §16 一致)
- internal/service/vehicle.go
* Create 时若 default_vehicle=true,事务内先 ClearDefault 再 Insert,
避免出现两个默认车辆
* Update 同样事务化 default 切换
* SetDefault 是显式接口,业务上"切默认车"是常用操作
全部错误用 apperror 包成 NotFound / InvalidArg / Internal
- internal/service/refuel_record.go
* Create:校验车辆存在 + Liters > 0 + TotalAmount >= 0,服务端
实时计算 price_per_liter,RefuelTime 统一转 UTC 存库
* Update:patch 语义,liters / total_amount 任一变更都重新算
price_per_liter(否则历史单价会失真)
* Statistics(单车):返回 累计次数 / 累计升数 / 累计金额 / 平均油价 /
标准百公里油耗 / 每公里成本 / 最近一次加油
关键实现:仅在"连续两次 is_full=true"之间采油耗样本,
半箱油 / 部分加油记录不会污染标准油耗 ——
这条规则直接来自 plan §6.3 与 §19 验收要求
业务规则(AGENTS.md 强约束):
车辆名称 / 能源类型 不允许为空(trim 后空字符串也拒)
加油量 > 0、总金额 >= 0、里程 >= 0 都在 service 入参立即校验
RefuelTime 统一 UTC 存库,展示按本地时区格式化
默认车辆唯一,切换走事务,杜绝"两个默认"
未做(留给 Phase 1.3b 下一个 commit):
- HTTP handler / router / main 装配
- 单元测试(本文件不含测试,等所有 service 稳定后单独提一个测试 commit)
- Dashboard / 统计 API(基础 Statistics 已就绪,Dashboard endpoint
留给 Phase 1.3b 末尾)
