# Context 超时控制改进工作总结
|
||||
|
||||
**时间**: 2026-06-10
|
||||
**任务**: Week 3-4 - 为所有核心模块添加 Context 超时控制
|
||||
|
||||
---
|
||||
|
||||
## 🎯 目标
|
||||
|
||||
为所有 Repository 和 Service 层方法添加 `context.Context` 参数,实现:
|
||||
1. 数据库操作超时控制
|
||||
2. 请求取消传播
|
||||
3. 优雅的超时错误处理
|
||||
4. 提升系统稳定性和可控性
|
||||
|
||||
---
|
||||
|
||||
## ✅ 已完成工作
|
||||
|
||||
### 1. Wallet 模块(100% 完成)
|
||||
|
||||
#### Repository 层
|
||||
- ✅ `Account(ctx context.Context, userID uint64) (*AccountDTO, error)`
|
||||
- ✅ `Ledger(ctx context.Context, userID uint64, page, pageSize int) (*PaginatedResult, error)`
|
||||
- ✅ `Recharge(ctx context.Context, userID uint64, amountCent int64) (*AccountDTO, error)`
|
||||
- ✅ `ConfirmRechargeFromChannel(ctx context.Context, userID uint64, bizNo string, amountCent int64) error`
|
||||
- ✅ `Withdraw(ctx context.Context, userID uint64, amountCent int64) (*AccountDTO, error)`
|
||||
- ✅ `AdminLedger(ctx context.Context, query AdminLedgerQuery) (*PaginatedResult, error)`
|
||||
|
||||
#### Service 层
|
||||
- ✅ 所有方法签名已更新,添加 `ctx context.Context` 作为第一个参数
|
||||
- ✅ 所有对 Repository 的调用已传递 context
|
||||
|
||||
#### Handler 层
|
||||
- ✅ 所有 handler 方法使用 `c.Request.Context()` 获取请求上下文
|
||||
- ✅ Context 从 HTTP 请求传递到 Service 再到 Repository
|
||||
|
||||
#### 测试代码
|
||||
- ✅ Service 测试已更新(5 个测试)
|
||||
- ✅ Repository 集成测试已更新(9 个测试)
|
||||
- ✅ Repository 逻辑测试已更新(14 个测试)
|
||||
- ✅ 所有测试通过
|
||||
|
||||
#### 数据库操作
|
||||
- ✅ 所有数据库查询使用 `db.WithContext(ctx)`
|
||||
- ✅ 事务操作传播 context

|

---
|
||||
|
||||
## 📋 实施建议
|
||||
|
||||
### 方案 A:手动逐模块修改(推荐)
|
||||
|
||||
**优点**:
|
||||
- 精确控制每个修改
|
||||
- 可以同步优化代码结构
|
||||
- 确保测试全部通过
|
||||
|
||||
**缺点**:
|
||||
- 工作量大(预估 8-12 小时)
|
||||
- 需要逐个测试验证
|
||||
|
||||
**步骤**:
|
||||
1. 按模块优先级排序:order → payment → listing → 其他
|
||||
2. 每个模块按层级修改:Repository → Service → Handler → Tests
|
||||
3. 每完成一个模块,运行测试验证
|
||||
4. 提交一次代码
|
||||
|
||||
---
|
||||
|
||||
### 方案 B:自动化脚本批量修改(快速但风险高)
|
||||
|
||||
**优点**:
|
||||
- 快速完成(1-2 小时)
|
||||
- 统一规范
|
||||
|
||||
**缺点**:
|
||||
- 可能引入错误
|
||||
- 需要大量测试验证
|
||||
- 可能遗漏边界情况
|
||||
|
||||
**不推荐原因**:
|
||||
- 各模块方法签名差异较大
|
||||
- 有些方法可能已有 context 参数
|
||||
- 测试代码结构复杂,难以批量处理
|
||||
|
||||
---
|
||||
|
||||
### 方案 C:分阶段实施(平衡方案)
|
||||
|
||||
**第一阶段(本次)**:
|
||||
- ✅ Wallet 模块(已完成)
|
||||
|
||||
**第二阶段(下次)**:
|
||||
- Order 模块(核心业务,优先级最高)
|
||||
- Payment 模块(核心业务,优先级最高)
|
||||
|
||||
**第三阶段(后续)**:
|
||||
- Listing、Dispute、Realname 等模块
|
||||
|
||||
**提交策略**:
|
||||
- 每完成一个模块,提交一次
|
||||
- 保持每次提交的原子性和可回滚性
|
||||
|
||||

|
||||
|
||||

|

|
||||
## 🔍 实施细节
|
||||
|
||||
### Context 传递链路
|
||||
|
||||
```
|
||||
HTTP Request
|
||||
↓
|
||||
Handler (c.Request.Context())
|
||||
↓
|
||||
Service (ctx context.Context, ...)
|
||||
↓
|
||||
Repository (ctx context.Context, ...)
|
||||
↓
|
||||
GORM (db.WithContext(ctx))
|
||||
```
|
||||
|
||||
### 超时控制示例
|
||||
|
||||
```go
|
||||
// Handler 层设置超时
|
||||
func (h *Handler) CreateOrder(c *gin.Context) {
|
||||
ctx, cancel := context.WithTimeout(c.Request.Context(), 5*time.Second)
|
||||
defer cancel()
|
||||
|
||||
order, err := h.service.Create(ctx, userID, req)
|
||||
// ...
|
||||
}
|
||||
|
||||
// Repository 层传播 context
|
||||
func (r *Repository) Create(ctx context.Context, userID uint64, req CreateRequest) error {
|
||||
return r.db.WithContext(ctx).Transaction(func(tx *gorm.DB) error {
|
||||
// 事务内的所有操作都会使用 ctx 的超时控制
|
||||
// ...
|
||||
})
|
||||
}
|
||||
```
|
||||
|
||||
### 测试代码模式
|
||||
|
||||
```go
|
||||
func TestRepositoryMethod(t *testing.T) {
|
||||
db := setupTestDB(t)
|
||||
defer cleanupTestDB(t, db)
|
||||
|
||||
repo := NewRepository(db)
|
||||
ctx := context.Background()
|
||||
|
||||
result, err := repo.Method(ctx, params)
|
||||
// ...
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## ✅ 验证清单
|
||||
|
||||
每个模块完成后需要验证:
|
||||
|
||||
- [ ] 所有 Repository 方法签名已更新
|
||||
- [ ] 所有 Service 方法签名已更新
|
||||
- [ ] 所有 Handler 方法已传递 context
|
||||
- [ ] 所有数据库操作使用 `WithContext(ctx)`
|
||||
- [ ] 所有测试代码已更新
|
||||
- [ ] 所有测试通过(`go test ./internal/modules/<module> -v`)
|
||||
- [ ] 代码编译通过(`go build ./internal/modules/<module>`)
|
||||
- [ ] 无 lint 错误(`golangci-lint run ./internal/modules/<module>`)
|
||||
|
||||

|
||||
|
||||
## 📝 注意事项
|
||||
|
||||
1. **向后兼容性**:这是一个破坏性变更(breaking change),所有调用方都需要更新
|
||||
2. **超时时间设置**:
|
||||
- 简单查询:2-5s
|
||||
- 复杂查询:5-10s
|
||||
- 事务操作:10-30s
|
||||
- 外部 API 调用:根据 SLA 设置
|
||||
3. **错误处理**:需要区分超时错误和业务错误
|
||||
4. **测试覆盖**:确保所有路径都覆盖到 context 取消场景
|
||||
