权限跳转逻辑异常：未授权用户访问会议管理页问题

Got it, let's break down these two permission control issues and walk through how to fix them—they're common pitfalls in auth and route protection flows, but totally resolvable with targeted checks:

Here's what to check and fix:

• First, confirm your global auth guard/middleware is running on all restricted page routes. If the guard skips any routes that require authorization, unauthenticated users might land on those pages instead of being redirected.
• Verify the redirect logic in your guard: When an unauthenticated user is detected, explicitly trigger a redirect to your homepage route (e.g., /). Don't rely on implicit routing—make sure the redirect target is hardcoded or pulled from a correctly configured value.
• If you're using a frontend framework, double-check route guard attachment. For example, in Vue Router, ensure you've added a beforeEach global hook or beforeEnter route-specific guard that handles unauthenticated cases. Here's a quick example:

  router.beforeEach(async (to, from, next) => {
    const isAuthenticated = await checkUserAuth();
    if (to.meta.requiresAuth && !isAuthenticated) {
      next('/'); // Redirect to homepage
    } else {
      next();
    }
  });
  

This has two sub-cases to address:

Sub-case A: Unauthenticated users accessing /proj.test/conference/manage/2 don't redirect to login #

• Prioritize auth checks over permission checks: Your auth guard should run before any conference-specific ownership validation. If the user isn't logged in, redirect them to the login page immediately—don't waste time checking conference ownership first.
• Ensure the conference manage route isn't nested under an unprotected parent route. If it is, the auth guard might not apply. Either move it under a protected parent or attach the auth guard directly to this route.

Sub-case B: Authenticated non-creator users don't redirect to homepage #

• Fix the ownership validation logic: When loading the conference manage page, fetch the conference's creator ID from your backend/database, then compare it with the current authenticated user's ID. If they don't match, trigger a redirect to the homepage.
• Never rely solely on client-side checks: Always validate ownership on the backend too. The API endpoint that returns conference details should return a 403 Forbidden status if the user isn't the creator, and your frontend should handle this error by redirecting.
• Check for async race conditions: If you're fetching conference data asynchronously, make sure the redirect happens only after the data loads and the ownership check completes. Use async/await or promise chaining to ensure the check runs before rendering the page:

  async function loadConferenceDetails(conferenceId) {
    const conference = await fetchConference(conferenceId);
    const currentUserId = getCurrentUserId();
    if (conference.creatorId !== currentUserId) {
      window.location.href = '/'; // Redirect to homepage
      return;
    }
    // Render the page if ownership is confirmed
  }
