Summary

Fixes race condition where SWR fires API requests before AuthContext completes loading authentication token from localStorage, resulting in Authorization: Bearer null errors.

Problem

When users refresh the page or directly access trader pages:

  1. Component renders → SWR evaluates key conditions
  2. Immediately fires request → but token still loading from localStorage
  3. getAuthHeaders() returns null → request sent with Authorization: Bearer null
  4. Backend rejects with "token is malformed: invalid number of segments"

Error Example:

GET /api/account?trader_id=xxxxxx
Authorization: Bearer null
→ {"error": "无效的token: token is malformed: token contains an invalid number of segments"}

Root Cause

SWR key conditions only checked page state, not authentication state:

// ❌ Before: Race condition
const { data: account } = useSWR(
  currentPage === 'trader' && selectedTraderId ? 'account-...' : null,
  () => api.getAccount(...)
)

Solution

Add user && token && checks to all authenticated SWR keys to ensure requests only fire after authentication completes:

// ✅ After: Wait for auth
const { data: account } = useSWR(
  user && token && currentPage === 'trader' && selectedTraderId
    ? 'account-...'
    : null,
  () => api.getAccount(...)
)

Changes

web/src/App.tsx

  • ✅ Import useAuth hook from AuthContext
  • ✅ Add user && token && to 5 authenticated SWR calls:
    • status (line 92)
    • account (line 104)
    • positions (line 116)
    • decisions (line 128)
    • stats (line 140)

web/src/components/EquityChart.tsx

  • ✅ Import useAuth hook from AuthContext
  • ✅ Add user && token && to 2 authenticated SWR calls:
    • history (line 37)
    • account (line 47)

Impact

  • Eliminates "Bearer null" errors on page refresh
  • Prevents malformed token errors when accessing trader pages
  • Consistent with existing pattern (traders list already uses this check)
  • No breaking changes - purely additive guard conditions

Testing

  • ✅ TypeScript compilation: npx tsc --noEmit
  • ✅ Pattern verified against working traders SWR call (App.tsx line 105)
  • ✅ Manual testing: refresh trader page no longer shows errors

Fixes #634

When users refresh the page or directly access trader pages, SWR immediately
fires API requests before AuthContext finishes loading the token from
localStorage, causing requests with `Authorization: Bearer null`.

**Error Example:**
```
GET /api/account?trader_id=xxxxxx
Authorization: Bearer null
→ {"error": "无效的token: token is malformed: token contains an invalid number of segments"}
```

SWR key conditions only checked `currentPage` and `selectedTraderId`:
```typescript
// ❌ Before: Missing auth check
const { data: account } = useSWR(
  currentPage === 'trader' && selectedTraderId ? 'account-...' : null,
  () => api.getAccount(...)
)
```

This created a race condition:
1. App renders → SWR evaluates key → fires request
2. AuthContext still loading → `token = null`
3. getAuthHeaders() gets `null` → `Bearer null`

Add `user && token &&` to all authenticated SWR keys:
```typescript
// ✅ After: Wait for authentication
const { data: account } = useSWR(
  user && token && currentPage === 'trader' && selectedTraderId
    ? 'account-...'
    : null,
  () => api.getAccount(...)
)
```

Fixed 5 SWR calls:
- ✅ `status` (line 92): Added `user && token &&`
- ✅ `account` (line 104): Added `user && token &&`
- ✅ `positions` (line 116): Added `user && token &&`
- ✅ `decisions` (line 128): Added `user && token &&`
- ✅ `stats` (line 140): Added `user && token &&`

- ✅ Import `useAuth` hook
- ✅ Fix `history` SWR (line 37): Added `user && token &&`
- ✅ Fix `account` SWR (line 47): Added `user && token &&`

- ✅ Eliminates "Bearer null" errors on page refresh
- ✅ Prevents malformed token errors when editing traders
- ✅ Consistent with existing pattern (see line 105: traders list already uses this)

- ✅ TypeScript compilation: `npx tsc --noEmit`
- ✅ Pattern verified against working `traders` SWR call

Fixes NoFxAiOS#634

代码审查报告 - PR #669

审查结果:✅ 通过(安全增强)

业务层面审查

✅ 需求验证

✅ 功能完整性

  • App.tsx中5个SWR调用添加token检查
  • EquityChart.tsx中2个SWR调用添加token检查
  • 所有需要认证的API调用都被保护

技术层面审查

✅ 问题分析

安全漏洞

// Before - 未检查认证状态
const { data: status } = useSWR<SystemStatus>(
  currentPage === 'trader' && selectedTraderId
    ? `status-${selectedTraderId}`
    : null,
  () => api.getStatus(selectedTraderId),
  { refreshInterval: 10000 }
)

// 问题:
// 1. 即使 token = null,仍然会调用 API
// 2. 后端收到 null token,返回 401
// 3. 前端无限重试(refreshInterval: 10000)
// 4. 产生大量无效请求 ❌

影响

  • 浪费网络资源
  • 产生无意义的401错误日志
  • 可能触发后端限流
  • 用户体验差(控制台报错)

✅ 解决方案

添加认证检查

// After - 添加 user && token 检查
const { data: status } = useSWR<SystemStatus>(
  user && token && currentPage === 'trader' && selectedTraderId
    ? `status-${selectedTraderId}`
    : null,
  () => api.getStatus(selectedTraderId),
  { refreshInterval: 10000 }
)

工作原理

  1. SWR key为null时,不会调用fetcher函数
  2. user && token 确保用户已登录
  3. 未登录时,key = null,不会发起API请求
  4. 登录后,key变为有效值,开始请求数据

✅ 修改覆盖

App.tsx (5处修改)

  1. status - 系统状态
  2. account - 账户信息
  3. positions - 持仓列表
  4. decisions - 决策记录
  5. stats - 统计信息

EquityChart.tsx (2处修改)

  1. history - 权益历史
  2. account - 账户信息

总计:7个需要认证的API调用全部保护 ✅

E2E 验证报告

✅ 测试场景1:未登录用户

状态:user = null, token = null
页面:trader页面

预期:
- 不发起任何API请求
- 无401错误
- 控制台干净

实际:✅ 符合预期

✅ 测试场景2:登录用户

状态:user = {...}, token = "xxx"
页面:trader页面

预期:
- 正常发起API请求
- 获取数据成功
- 数据正常显示

实际:✅ 符合预期

✅ 测试场景3:登出场景

操作:
1. 用户已登录,数据正常显示
2. 用户点击登出

预期:
- token清除后,停止API轮询
- 不再发起新的请求
- 页面跳转到登录页

实际:✅ 符合预期(SWR key变为null)

✅ 测试场景4:Token过期

状态:token过期
操作:页面刷新

预期:
- 不发起API请求(因为认证流程会先清除token)
- 重定向到登录页
- 无无效请求

实际:✅ 符合预期(配合PR #685的HttpClient)

代码质量审查

✅ 一致性

所有检查都使用相同模式

user && token && otherConditions ? key : null

顺序正确

  • 先检查认证状态(user && token)
  • 再检查业务条件(currentPage, selectedTraderId)

✅ SWR最佳实践

条件请求

// ✅ 正确:使用 null key 阻止请求
useSWR(
  shouldFetch ? key : null,
  fetcher
)

// ❌ 错误:在 fetcher 中检查
useSWR(
  key,
  () => shouldFetch ? api.get() : null  // 仍会调用 fetcher
)

本PR采用:✅ 正确模式

✅ 性能优化

减少无效请求

  • Before: 可能每10秒发送7个401请求
  • After: 未登录时,0个请求

网络流量节省

  • 7个API × 10秒间隔 × 60秒 = 42个请求/分钟
  • 节省100%无效请求

安全审查

✅ 认证保护

防御层级

  1. 前端层(本PR):阻止未授权请求
  2. 网络层(PR fix: 修复token过期未重新登录的问题 #685):HttpClient拦截401
  3. 后端层:验证token有效性

纵深防御

✅ 防止信息泄露

Before

  • 未登录用户可能看到401错误细节
  • 控制台可能暴露API端点

After

  • 未登录用户不会触发API调用
  • 无错误信息泄露

✅ 符合最小权限原则

  • 未登录 → 无API调用权限
  • 已登录 → 仅调用授权API

🟡 改进建议(非 BLOCKING)

建议1:提取认证检查Hook

// src/hooks/useAuthenticatedSWR.ts
export function useAuthenticatedSWR<T>(
  key: string | null,
  fetcher: () => Promise<T>,
  options?: SWRConfiguration
) {
  const { user, token } = useAuth()
  
  return useSWR<T>(
    user && token && key ? key : null,
    fetcher,
    options
  )
}

// 使用
const { data: status } = useAuthenticatedSWR(
  currentPage === 'trader' && selectedTraderId
    ? `status-${selectedTraderId}`
    : null,
  () => api.getStatus(selectedTraderId),
  { refreshInterval: 10000 }
)

优点

  • DRY(Don't Repeat Yourself)
  • 集中管理认证逻辑
  • 更容易维护

建议2:添加loading状态

const { data, error, isLoading } = useAuthenticatedSWR(...)

if (!user || !token) {
  return <LoginPrompt />
}

if (isLoading) {
  return <Skeleton />
}

if (error) {
  return <ErrorMessage />
}

return <DataDisplay data={data} />

建议3:添加TypeScript类型守卫

function isAuthenticated(user: User | null, token: string | null): user is User {
  return user !== null && token !== null
}

// 使用
const { user, token } = useAuth()

if (!isAuthenticated(user, token)) {
  return <LoginPrompt />
}

// TypeScript知道这里 user 一定不是 null
const { data } = useSWR(`status-${user.id}`, ...)

建议4:添加单元测试

describe('API authentication checks', () => {
  it('does not call API when user is not logged in', () => {
    const mockFetcher = jest.fn()
    
    renderHook(() => 
      useSWR(
        user && token && condition ? key : null,
        mockFetcher
      ),
      { wrapper: createWrapper({ user: null, token: null }) }
    )
    
    expect(mockFetcher).not.toHaveBeenCalled()
  })
  
  it('calls API when user is logged in', () => {
    const mockFetcher = jest.fn()
    
    renderHook(() => 
      useSWR(
        user && token && condition ? key : null,
        mockFetcher
      ),
      { wrapper: createWrapper({ user: {...}, token: 'xxx' }) }
    )
    
    expect(mockFetcher).toHaveBeenCalled()
  })
})

与其他PR的配合

…en prevention)

- Test SWR key generation with null/undefined user/token
- Test multiple API endpoints (status/account/positions/decisions/statistics)
- Test EquityChart API guard conditions
- Test edge cases (empty strings, undefined, numeric traderId, zero)
- Test API call prevention flow

All 25 test cases passed, covering:
1. SWR key generation (6 cases): null user/token, wrong page, no traderId, valid case
2. Multiple API endpoints (6 cases): all guarded endpoints + authenticated state
3. EquityChart guard (3 cases): unauthenticated, no traderId, valid
4. Edge cases (6 cases): empty string, undefined, numeric/zero traderId
5. API call prevention (4 cases): null key behavior, SWR simulation

Related to PR NoFxAiOS#669 - ensures no unauthorized API calls with null token.

Closing in favor of #880 - a clean rebuild from the latest dev branch without merge conflicts.

@the-dev-z the-dev-z closed this Nov 10, 2025
the-dev-z added a commit to the-dev-z/nofx that referenced this pull request Nov 10, 2025
Add `user && token &&` guard to all authenticated SWR calls to prevent
requests with `Authorization: Bearer null` when users refresh the page
before AuthContext finishes loading.

## Problem
When users refresh the page, SWR fires requests before AuthContext loads
the token from localStorage, causing "Bearer null" errors.

## Solution
Add auth check to SWR key conditions:
- ✅ App.tsx (5 SWR calls): status, account, positions, decisions, stats
  (traders already has guard in upstream/dev)
- ✅ EquityChart.tsx (2 SWR calls): history, account
- ✅ apiGuard.test.ts: 370 lines of comprehensive unit tests

## Testing
- ✅ TypeScript compilation passes for modified files
- ✅ 370 lines of unit tests covering all edge cases

Fixes NoFxAiOS#634
