+## 修复编译错误：TabCustomer 无 PrimaryPhone 字段
+
+- **问题**: `apiWarehouse.go:1177` 中 `c.PrimaryPhone undefined`
+- **原因**: `TabCustomer` 结构体没有 `PrimaryPhone` 字段，电话存储在独立的 `TabCustomerPhone` 表（`is_primary=true` 标记主号码）
+- **修复**: 改为从 `TabCustomerPhone` 表查询主号码，拼接格式 `+{Prefix} {Phone}`，文件：`routers/apiWarehouse.go`
