需求
针对driver_shipping_fee，buyer_shipping_fee做不同层级的运费计算
driver部分
配置项获取
Driver Shipping Fee
Module_DriverShippingFee = 7
message DriverShippingFee { optional BaseShippingFee shipping_fee = 1; optional uint64 commission_rate = 2; // 乘1w后保存, 20%=0.2, 0.2*1w=2000 }
message BaseShippingFee { optional uint64 min_shipping_fee = 1; // 乘10w后保存 repeated ShippingFeeTier tiers = 2; }
message ShippingFeeTier { optional uint64 tier_start = 1; // 单位：m optional uint64 tier_end = 2; // 单位：m optional uint64 fixed_fee = 3; // 乘10w后保存 optional uint64 fare = 4; // 乘10w后保存 }
获取area逻辑回归
根据destination的city，district，state进行解析
district_id有对应配置，area_id有对应配置，global有对应配置
默认读district_id对应配置
district_id没有对应配置，area_id有对应配置，global有对应配置
默认读area_id对应配置
district_id没有对应配置，area_id没有对应配置，global有对应配置
默认读global对应配置
district_id没有对应配置，area_id没有对应配置，global没有对应配置
获取为空，读代码默认配置

数据项不符合规范
ShippingFeeTier 层级
当只有一个层级
第一个tier要从0开始
tier_start=0
可以正常解析获取对应参数
tier_start>0
解析异常调用兜底逻辑
tier_start<0
解析异常调用兜底逻辑
tier_end需要>tier_start
tier_end>tier_start
可以正常解析获取对应参数
tier_end<tier_start
解析异常调用兜底逻辑
tier_end=tier_start
解析异常调用兜底逻辑
当有多个层级
第一个tier要从0开始
tier_start=0
可以正常解析获取对应参数
tier_start>0
解析异常调用兜底逻辑
tier_start<0
解析异常调用兜底逻辑
每个层级tier_end需要>tier_starttier_begin和tier_end为三位小数
检查第一个层级和最后一个层级
tier_end>tier_start
可以正常解析获取对应参数
tier_end=tier_start
解析异常调用兜底逻辑
tier_end<tier_start
解析异常调用兜底逻辑
tier层级连续性
second_tier_begin 与 first_tier_end要相等tier_begin和tier_end为三位小数
second_tier_begin = first_tier_end
可以正常解析获取对应参数
second_tier_begin > first_tier_end
解析异常调用兜底逻辑
second_tier_begin < first_tier_end
解析异常调用兜底逻辑
tier层级最多10个
tier_num>10
解析异常调用兜底逻辑
tier_num=10
可以正常解析获取对应参数

配置区分partner/non-partner的纬度
计算公式
Buyer Shipping Fee = (MAX {Buyer Minimum Fee, CUMULATIVE [Buyer Fixed Fee + Distance * Buyer Fare/km]} * Buyer Surge Multiplier + Buyer Surge Fixed Fee
配置样例
{ "buyer_shipping_fee": { "partner_shipping_fee": { "min_shipping_fee": 200000, "tiers": [{ "tier_start": 0, "tier_end": 2000, "fixed_fee": 200000, "fare": 0 }, { "tier_start": 2000, "tier_end": 3000, "fixed_fee": 100000, "fare": 0 }, { "tier_start": 3000, "tier_end": 6000, "fixed_fee": 100000, "fare": 0 }, { "tier_start": 6000, "tier_end": 9000, "fixed_fee": 100000, "fare": 0 }, { "tier_start": 9000, "tier_end": 100000, "fixed_fee": 300000, "fare": 0 }] }, "non_partner_shipping_fee": { "min_shipping_fee": 200000, "tiers": [{ "tier_start": 0, "tier_end": 2000, "fixed_fee": 200000, "fare": 0 }, { "tier_start": 2000, "tier_end": 3000, "fixed_fee": 100000, "fare": 0 }, { "tier_start": 3000, "tier_end": 6000, "fixed_fee": 100000, "fare": 0 }, { "tier_start": 6000, "tier_end": 9000, "fixed_fee": 100000, "fare": 0 }, { "tier_start": 9000, "tier_end": 100000, "fixed_fee": 300000, "fare": 0 }] } }}

配置项
默认值
获取配置
格式，边界校验
待确认事项
surge fee的接口代码和数据库结构需变更，此次可以读默认配置，不影响，后续若想支持admin配置，algo需再做开发
distance
走降级逻辑时候，计算的distance会有小数，我们会丢这个结果做取整处理
运营配置缺失，比如没有non-parter的配置
风险自行承担
前端针对配置会乘以5个0保存
th/my的货币单位不一样，也需要乘以5个0？
我们现在的取整逻辑是先除以5个0，进行计算，取整，然后再乘以5个0
