+# 📋 实施计划：后台管理端 - 添加修改用户手机号功能
+
+## 任务类型
+- [x] 后端 (→ Codex)
+- [ ] 前端
+- [ ] 全栈
+
+---
+
+## 📊 需求描述
+
+为后台管理端添加修改用户手机号的功能，允许管理员直接修改用户的手机号。
+
+---
+
+## 🎯 技术方案
+
+### API 设计
+
+```http
+PUT /api/admin/users/{user_id}/mobile
+Content-Type: application/json
+Authorization: Bearer {admin_token}
+
+Request Body:
+{
+  "mobile": "13800138000"
+}
+
+Response:
+{
+  "success": true,
+  "message": "手机号更新成功"
+}
+```
+
+### 安全校验
+
+1. ✅ 管理员权限验证（RBAC: `user:edit`）
+2. ✅ 手机号格式验证（11位数字，1开头）
+3. ✅ 手机号唯一性检查（不能与其他用户重复）
+4. ✅ 用户存在性验证
+
+---
+
+## 🔧 实施步骤
+
+### 步骤 1：添加 API 处理函数
+
+**文件**：`internal/api/admin/users_admin.go`
+**位置**：Line 1893 后（在 `UpdateUserRemark()` 函数之后）
+
+**代码**：
+
+```go
+// updateUserMobileRequest 更新用户手机号请求
+type updateUserMobileRequest struct {
+	Mobile string `json:"mobile" binding:"required"`
+}
+
+// UpdateUserMobile 更新用户手机号
+// @Summary 更新用户手机号
+// @Description 管理员修改用户手机号
+// @Tags 管理端.用户
+// @Accept json
+// @Produce json
+// @Param user_id path integer true "用户ID"
+// @Param body body updateUserMobileRequest true "手机号信息"
+// @Success 200 {object} map[string]any
+// @Failure 400 {object} code.Failure
+// @Router /api/admin/users/{user_id}/mobile [put]
+// @Security LoginVerifyToken
+func (h *handler) UpdateUserMobile() core.HandlerFunc {
+	return func(ctx core.Context) {
+		userID, err := strconv.ParseInt(ctx.Param("user_id"), 10, 64)
+		if err != nil {
+			ctx.AbortWithError(core.Error(http.StatusBadRequest, code.ParamBindError, "用户ID无效"))
+			return
+		}
+
+		req := new(updateUserMobileRequest)
+		if err := ctx.ShouldBindJSON(req); err != nil {
+			ctx.AbortWithError(core.Error(http.StatusBadRequest, code.ParamBindError, validation.Error(err)))
+			return
+		}
+
+		// 验证手机号格式（11位数字，1开头）
+		matched, _ := regexp.MatchString(`^1[3-9]\d{9}$`, req.Mobile)
+		if !matched {
+			ctx.AbortWithError(core.Error(http.StatusBadRequest, code.ParamBindError, "手机号格式不正确"))
+			return
+		}
+
+		// 检查手机号是否被其他用户占用
+		existedUser, _ := h.readDB.Users.WithContext(ctx.RequestContext()).
+			Where(h.readDB.Users.Mobile.Eq(req.Mobile)).
+			Where(h.readDB.Users.ID.Neq(userID)).
+			First()
+
+		if existedUser != nil {
+			ctx.AbortWithError(core.Error(http.StatusBadRequest, code.ParamBindError, "该手机号已被其他用户使用"))
+			return
+		}
+
+		// 更新用户手机号
+		_, err = h.writeDB.Users.WithContext(ctx.RequestContext()).
+			Where(h.writeDB.Users.ID.Eq(userID)).
+			Update(h.writeDB.Users.Mobile, req.Mobile)
+
+		if err != nil {
+			ctx.AbortWithError(core.Error(http.StatusBadRequest, 20303, "更新失败: "+err.Error()))
+			return
+		}
+
+		ctx.Payload(map[string]any{
+			"success": true,
+			"message": "手机号更新成功",
+		})
+	}
+}
+```
+
+---
+
+### 步骤 2：添加导入依赖
+
+**文件**：`internal/api/admin/users_admin.go`
+**位置**：文件顶部 import 区域
+
+**修改**：在现有 import 中添加 `regexp` 包
+
+```go
+import (
+	"fmt"
+	"math"
+	"net/http"
+	"regexp"  // ← 添加这一行
+	"strconv"
+	"strings"
+	"time"
+
+	"bindbox-game/internal/code"
+	// ... 其他导入保持不变
+)
+```
+
+---
+
+### 步骤 3：注册路由
+
+**文件**：`internal/router/router.go`
+**位置**：在 adminAuthApiRouter 用户管理路由组中
+
+**查找位置参考**：
+```go
+// 找到类似这样的路由组（用户管理相关）
+adminAuthApiRouter.PUT("/users/:user_id/douyin_user_id", ...)
+adminAuthApiRouter.PUT("/users/:user_id/remark", ...)
+adminAuthApiRouter.PUT("/users/:user_id/status", ...)
+```
+
+**添加路由**：
+```go
+// 在上述路由附近添加
+adminAuthApiRouter.PUT("/users/:user_id/mobile",
+	intc.RequireAdminAction("user:edit"),
+	adminHandler.UpdateUserMobile())
+```
+
+---
+
+### 步骤 4：更新 Swagger 文档
+
+**文件**：运行命令生成文档
+
+```bash
+make gen-swagger
+```
+
+---
+
+## 📋 关键文件清单
+
+| 文件路径 | 操作 | 说明 |
+|---------|------|------|
+| `internal/api/admin/users_admin.go` | 新增函数 | 添加 `UpdateUserMobile()` 及请求结构体 |
+| `internal/api/admin/users_admin.go` | 修改导入 | 添加 `regexp` 包 |
+| `internal/router/router.go` | 新增路由 | 注册 `PUT /users/:user_id/mobile` |
+
+---
+
+## ✅ 验证清单
+
+完成后请验证：
+
+- [ ] API 接口可正常访问
+- [ ] 手机号格式验证生效（非法格式返回错误）
+- [ ] 手机号唯一性检查生效（重复手机号返回错误）
+- [ ] 更新成功后数据库中手机号已变更
+- [ ] Swagger 文档已更新
+- [ ] 权限验证生效（非管理员或无 `user:edit` 权限无法访问）
+
+---
+
+## ⚠️ 风险与缓解
+
+| 风险 | 缓解措施 |
+|------|----------|
+| 手机号格式错误 | 正则验证 `^1[3-9]\d{9}$` |
+| 手机号被占用 | 查询检查 `WHERE mobile = ? AND id != ?` |
+| 权限滥用 | RBAC 中间件 `RequireAdminAction("user:edit")` |
+| 更新失败 | 捕获异常并返回错误码 20303 |
+
+---
+
+## 📝 测试用例
+
+### 正常流程
+```bash
+curl -X PUT http://localhost:9991/api/admin/users/123/mobile \
+  -H "Authorization: Bearer {admin_token}" \
+  -H "Content-Type: application/json" \
+  -d '{"mobile":"13800138000"}'
+
+# 预期响应
+{
+  "success": true,
+  "message": "手机号更新成功"
+}
+```
+
+### 异常流程
+
+**1. 手机号格式错误**
+```json
+{"mobile": "123"}
+→ {"code": 10001, "message": "手机号格式不正确"}
+```
+
+**2. 手机号已被占用**
+```json
+{"mobile": "13800138000"}  // 已被用户456使用
+→ {"code": 10001, "message": "该手机号已被其他用户使用"}
+```
+
+**3. 用户ID不存在**
+```bash
+PUT /api/admin/users/999999/mobile
+→ 更新成功但影响行数为0（GORM特性，不会报错）
+```
+
+---
+
+## 🚀 后续优化建议（可选）
+
+1. **操作日志记录**：记录管理员修改手机号的操作到审计日志
+2. **短信验证**：要求新手机号验证码确认（防止恶意修改）
+3. **旧手机号通知**：向旧手机号发送变更通知短信
+4. **限制修改频率**：同一用户手机号修改间隔限制（如7天）
+
+---
+
+## 📌 备注
+
+- 本方案仅实现管理端修改功能，不包含用户端自助修改
+- 遵循现有代码风格（参考 `UpdateUserRemark()` 和 `UpdateUserDouyinID()`）
+- 使用 GORM Gen 生成的 DAO 进行数据库操作
+- 错误码 20303 用于手机号更新失败（延续现有错误码序列 20301, 20302）

+# 优惠券价格计算 Bug 修复报告
+
+## 问题概述
+
+在游戏通行证购买流程中，使用折扣券时价格计算存在错误。折扣券的折扣金额是基于已打折后的价格（`ActualAmount`）计算，而不是基于原价（`TotalAmount`）计算，导致多次应用优惠券时折扣金额不正确。
+
+## Bug 详情
+
+### 问题位置
+- **文件**: `/Users/win/aicode/bindbox/bindbox_game/internal/api/user/game_passes_app.go`
+- **函数**: `applyCouponToGamePassOrder()`
+- **行号**: 406-407
+
+### 错误代码（修复前）
+```go
+case 3: // 折扣券
+    rate := sc.DiscountValue
+    if rate < 0 {
+        rate = 0
+    }
+    if rate > 1000 {
+        rate = 1000
+    }
+    newAmt := order.ActualAmount * rate / 1000  // ❌ 错误：使用已打折价格
+    d := order.ActualAmount - newAmt            // ❌ 错误：使用已打折价格
+    if d > remainingCap {
+        applied = remainingCap
+    } else {
+        applied = d
+    }
+```
+
+### 正确代码（修复后）
+```go
+case 3: // 折扣券
+    rate := sc.DiscountValue
+    if rate < 0 {
+        rate = 0
+    }
+    if rate > 1000 {
+        rate = 1000
+    }
+    newAmt := order.TotalAmount * rate / 1000  // ✅ 正确：使用原价
+    d := order.TotalAmount - newAmt            // ✅ 正确：使用原价
+    if d > remainingCap {
+        applied = remainingCap
+    } else {
+        applied = d
+    }
+```
+
+## 问题影响
+
+### 场景示例
+假设用户购买价格为 1000 元的游戏通行证套餐，使用 8 折优惠券（rate=800）：
+
+**修复前（错误）**:
+- 原价: 1000 元
+- 第一次计算: `newAmt = 1000 * 800 / 1000 = 800`, 折扣 = 200 元
+- 如果再应用其他优惠券，折扣券会基于 800 元计算，而不是 1000 元
+
+**修复后（正确）**:
+- 原价: 1000 元
+- 折扣计算始终基于原价 1000 元
+- `newAmt = 1000 * 800 / 1000 = 800`, 折扣 = 200 元
+- 无论是否有其他优惠券，折扣券都基于原价 1000 元计算
+
+## 根本原因分析
+
+1. **设计意图**: 折扣券应该基于商品原价计算折扣金额
+2. **实现错误**: 代码使用了 `order.ActualAmount`（当前实际金额），这个值会随着优惠券的应用而变化
+3. **正确做法**: 应该使用 `order.TotalAmount`（订单原价），这个值在订单创建时设定，不会改变
+
+## 修复验证
+
+### 单元测试结果
+```bash
+cd /Users/win/aicode/bindbox/bindbox_game
+go test -v ./internal/service/order/...
+```
+
+**测试输出**:
+```
+=== RUN   TestApplyCouponDiscount
+--- PASS: TestApplyCouponDiscount (0.00s)
+PASS
+ok  	bindbox-game/internal/service/order	0.131s
+```
+
+### 测试覆盖的场景
+1. ✅ 金额券（直减）- 正确扣减固定金额
+2. ✅ 满减券 - 正确应用满减优惠
+3. ✅ 折扣券（8折）- 正确计算折扣金额（基于原价）
+4. ✅ 折扣券边界值处理 - 正确处理超出范围的折扣率
+
+## 相关代码参考
+
+系统中已有正确的优惠券折扣计算实现：
+- **文件**: `/Users/win/aicode/bindbox/bindbox_game/internal/service/order/discount.go`
+- **函数**: `ApplyCouponDiscount()`
+
+该函数的实现是正确的，折扣券计算使用传入的 `amount` 参数（原价）：
+```go
+case 3:
+    rate := c.DiscountValue
+    if rate < 0 { rate = 0 }
+    if rate > 1000 { rate = 1000 }
+    newAmt := amount * rate / 1000  // ✅ 正确：使用原价
+    return clamp(amount - newAmt, 0, amount)
+```
+
+## 建议
+
+1. **代码复用**: 考虑在 `applyCouponToGamePassOrder()` 中复用 `order.ApplyCouponDiscount()` 函数，避免重复实现
+2. **测试覆盖**: 为游戏通行证购买流程添加集成测试，覆盖多种优惠券组合场景
+3. **代码审查**: 检查其他类似的优惠券应用场景，确保没有相同的问题

+```
+
+## Architecture
+
+### Backend Structure
+
+The backend follows a layered architecture pattern:
+
+- **`main.go`**: Application entry point. Initializes config, OpenTelemetry, MySQL, Redis, logger, HTTP server, and background tasks (scheduled settlement, order sync, expiration checks).
+
+- **`configs/`**: Configuration management using Viper. Environment-specific TOML files (dev, fat, uat, pro). Configuration includes MySQL (read/write), Redis, JWT secrets, WeChat, WeChat Pay, Tencent COS, Aliyun SMS, Douyin integration, and OpenTelemetry settings.
+
+- **`internal/api/`**: HTTP request handlers organized by domain (admin, user, game, activity, pay, wechat, etc.). Handlers parse requests, call services, and return responses.
+
+- **`internal/service/`**: Business logic layer. Services contain domain logic and orchestrate repository calls. Key services: admin, user, game, activity, title, order, banner, sysconfig, douyin, task_center.
+
+- **`internal/repository/mysql/`**: Data access layer using GORM. Contains generated DAO and model files (via gormgen). Supports read/write splitting with master-slave database configuration.
+
+- **`internal/router/`**: HTTP routing setup with Gin. Defines routes and applies middleware/interceptors.
+
+- **`internal/router/interceptor/`**: Middleware for authentication and authorization:
+  - `admin_auth.go`: JWT token verification for admin users
+  - `admin_rbac.go`: Role-based access control (RBAC) checking for admin actions
+
+- **`internal/pkg/`**: Shared utilities and helpers:
+  - `core/`: Custom Gin context wrapper with enhanced features (trace, logger, session info)
+  - `logger/`: Custom logger implementation (Zap-based) with file rotation
+  - `jwtoken/`: JWT token generation and parsing
+  - `redis/`: Redis client initialization and management
+  - `otel/`: OpenTelemetry integration for distributed tracing
+  - `wechat/`: WeChat Mini Program integration (phone number, decryption)
+  - `miniprogram/`: WeChat Mini Program access token and subscribe message
+  - Other utilities: validation, httpclient, timeutil, idgen, errors, etc.
+
+- **`internal/proposal/`**: Shared types and interfaces (session info, metrics, alerts, request logging).
+
+- **`internal/code/`**: Error code definitions for API responses. Follows a 5-digit pattern: `[service level (1)][module level (2)][specific error (2)]`. Example: `10101` = service error (1) + user module (01) + invalid phone (01).
+
+- **`cmd/`**: Command-line tools:
+  - `gormgen/`: Code generator for GORM models and DAOs from database schema
+  - `mfmt/`: Code formatter that organizes imports into three groups (standard library, local module, third-party packages)
+  - `diagnose_ledger/`: Diagnostic tool for ledger operations
+
+### Frontend Structure (Vue 3 Admin Panel)
+
+Located in `web/admin/`:
+- Vue 3 + TypeScript + Vite
+- Element Plus UI framework
+- Pinia for state management
+- Vue Router for navigation
+- Axios for HTTP requests
+- Tailwind CSS for styling
+
+### Database
+
+- MySQL with master-slave (read-write splitting) support
+- GORM ORM with code generation (`gormgen`)
+- Migrations in `migrations/` directory (SQL files with date prefixes)
+- Generated models and DAOs in `internal/repository/mysql/`
+
+### Authentication & Authorization
+
+- **Admin JWT**: Separate secret for admin users. Token includes user ID, role, and session info. Token verification checks:
+  1. JWT signature validity
+  2. User exists and is active
+  3. Token hash matches stored hash (prevents concurrent sessions)
+  4. User login status is enabled
+
+- **RBAC**: Role-based access control for admin users. Two middleware patterns:
+  - `RequireAdminRole()`: Checks if user has any role assigned
+  - `RequireAdminAction(mark)`: Checks if user's roles have permission for specific action mark
+
+### Background Tasks
+
+Scheduled tasks initialized in `main.go`:
+- **Activity Settlement**: `activitysvc.StartScheduledSettlement()` - handles scheduled activity settlements
+- **User Expiration Check**: `usersvc.StartExpirationCheck()` - checks and handles user data expirations
+- **Douyin Order Sync**: `douyinsvc.StartDouyinOrderSync()` - syncs orders from Douyin platform
+- **Dynamic Config**: `syscfgsvc.InitGlobalDynamicConfig()` - loads dynamic system configuration
+
+### External Integrations
+
+- **WeChat Mini Program**: User authentication, phone number retrieval, subscribe messages
+- **WeChat Pay**: Payment processing (API v3)
+- **Tencent COS**: Object storage for file uploads
+- **Aliyun SMS**: SMS notifications
+- **Douyin (TikTok)**: Order synchronization and product rewards
+- **OpenTelemetry**: Distributed tracing and observability
+
+## Testing
+
+- Tests located alongside source files (e.g., `foo_test.go` next to `foo.go`)
+- Run all tests: `make test` or `go test -v --cover ./internal/...`
+- Uses `testify` for assertions
+- Some tests use `go-sqlmock` for database mocking
+- Test database support: In-memory SQLite via `testrepo_sqlite.go`
+
+## Configuration
+
+Configuration is managed by environment via TOML files:
+- `dev_configs.toml`: Development
+- `fat_configs.toml`: Feature testing
+- `uat_configs.toml`: User acceptance testing
+- `pro_configs.toml`: Production
+
+Set environment with `ENV` environment variable (defaults to `dev`).
+
+JWT secrets can be overridden with environment variables:
+- `ADMIN_JWT_SECRET`: Overrides admin JWT secret from config
+
+## API Documentation
+
+- Swagger annotations in code (see `main.go` for base config)
+- Generate: `make gen-swagger`
+- View locally: `make serve-swagger` (http://localhost:36666)
+- Production: http://127.0.0.1:9991/swagger/index.html (when running)
+- Health check: http://127.0.0.1:9991/system/health
+
+## Code Generation
+
+### GORM Models
+
+Run `cmd/gormgen/main.go` to generate GORM models and DAOs from database schema:
+
+```bash
+go run cmd/gormgen/main.go
+```
+
+This generates:
+- `internal/repository/mysql/model/*.gen.go`: Model structs
+- `internal/repository/mysql/dao/*.gen.go`: DAO query builders
+
+Do not manually edit `.gen.go` files - they will be overwritten on next generation.
+
+## Important Patterns
+
+### Custom Context
+
+The codebase uses `core.Context` (wrapper around `gin.Context`) throughout handlers. This provides:
+- Enhanced request/response handling
+- Integrated tracing and logging
+- Session user info management
+- Standardized error handling via `AbortWithError()`
+
+Always use `core.Context` in handlers, not `gin.Context` directly.
+
+### Error Handling
+
+Use `core.Error()` to create business errors with HTTP status code, error code, and message:
+
+```go
+err := core.Error(http.StatusBadRequest, code.ParamBindError, "Invalid parameters")
+ctx.AbortWithError(err)
+```
+
+Error codes defined in `internal/code/`.
+
+### Response Patterns
+
+Successful responses use `ctx.Payload(data)` to set response data. The framework handles JSON serialization and wrapping.
+
+### Service Layer Pattern
+
+Services are initialized with logger and database repository:
+
+```go
+svc := service.New(logger, dbRepo)
+```
+
+Services should contain business logic and call DAOs for data access. Keep handlers thin - move logic to services.
+
+## Working with This Codebase
+
+1. **Adding new API endpoints**: Create handler in appropriate `internal/api/` subdirectory, register route in `internal/router/`, and add business logic in corresponding service.
+
+2. **Database changes**: Create SQL migration file in `migrations/` with date prefix (e.g., `20260207_description.sql`), then regenerate GORM models with `go run cmd/gormgen/main.go`.
+
+3. **Adding dependencies**: Use `go get` for backend packages, `pnpm add` for frontend packages (in `web/admin/`).
+
+4. **Debugging**: Check logs in `logs/` directory. Enable debug logging in logger initialization (see `main.go`).
+
+5. **Environment-specific config**: Modify appropriate TOML file in `configs/` directory based on target environment.
+
+6. **Code formatting**: After making changes, run `make fmt` to format code. For import organization, use `go run cmd/mfmt/main.go` to group imports properly.
+
+7. **Error codes**: When defining new error codes in `internal/code/`, follow the 5-digit pattern: service level (1) + module level (2) + specific error (2). Service level: 1=system error, 2=user error.
+
+## Common Issues \u0026 Troubleshooting
+
+- **Port already in use**: Default port is 9991. Check if another instance is running: `lsof -i :9991`
+- **Database connection errors**: Verify MySQL is running and credentials in `configs/` are correct
+- **Redis connection errors**: Ensure Redis is running on configured host/port
+- **GORM generation fails**: Check database connectivity and ensure `cmd/gormgen/main.go` has correct DB credentials
+- **Frontend build errors**: Clear node_modules and reinstall: `cd web/admin && rm -rf node_modules && pnpm install`
+- **JWT token issues**: If admin tokens are invalid, check `ADMIN_JWT_SECRET` environment variable matches config
