From 612fd7864fb63da3efec0e0ac225b1b07ae234e4 Mon Sep 17 00:00:00 2001 From: ZhouYongyou <128128010+zhouyongyou@users.noreply.github.com> Date: Fri, 7 Nov 2025 09:13:59 +0800 Subject: [PATCH 1/3] fix(web): prevent unauthorized API calls with null token (#634) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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 #634 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- web/src/App.tsx | 10 +++++----- web/src/components/EquityChart.tsx | 6 ++++-- 2 files changed, 9 insertions(+), 7 deletions(-) diff --git a/web/src/App.tsx b/web/src/App.tsx index ef7fff6a8..541bde5f7 100644 --- a/web/src/App.tsx +++ b/web/src/App.tsx @@ -118,7 +118,7 @@ function App() { // 如果在trader页面，获取该trader的数据 const { data: status } = useSWR( -
