仅在注销时才尝试重定向到 Angular 中的登录页面

Question

我的 Angular 应用程序使用多个模块。 我设法使路由正常工作，应用程序通常重定向到“keeper/caregivers”，但我有一个问题：当我在根域名或 localhost:4200 中时，我已注销，它应该重定向我到登录页面。 相反，它停留在 keeper/caregivers 页面，并显示权限不足的错误（见下图）。 我尝试在我的拦截函数中添加重定向，但它似乎永远不会触发。 这是我的代码：app-routing-module

import {NgModule} from '@angular/core';
import {RouterModule, Routes} from '@angular/router';
import {DefaultLayoutComponent} from './layout/default.layout.component';
import {AdminLayoutComponent} from './layout/admin.layout.component';
import {HhaLayoutComponent} from './layout/hha.layout.component';


const routes: Routes = [
  { path: '', redirectTo: 'keeper', pathMatch: 'full' },

  {
    path: 'keeper',
    component: DefaultLayoutComponent,
    children: [
      {
        path: '',
        redirectTo: 'caregivers',
        pathMatch: 'full'
      },

      {
        path: '',
        loadChildren: () =>
          import('./caregivers/caregivers.module').then(
            (m) => m.CaregiversModule,
          ),

      },
      // {
      //   path: 'caregivers',
      //   // redirectTo: 'caregivers',
      //   pathMatch: 'full'
      // },
      {
        path: 'transactions',
        loadChildren: () =>
          import('./transactions/transactions.module').then(
            (m) => m.TransactionsModule
          ),

      },
      {
        path: 'dashboard',
        loadChildren: () =>
          import('./dashboard/dashboard.module').then(
            (m) => m.DashboardModule
          ),

      },

      {
        path: 'payback-schedule',
        loadChildren: () =>
          import('./payback-schedule/payback-schedule.module').then(
            (m) => m.PaybackScheduleModule,
          ),

      },

      {
        path: 'caregivers',
        loadChildren: () =>
          import('./caregivers/caregivers.module').then(
            (m) => m.CaregiversModule,
          ),

      },
    ],
  },

  {
    path: 'admin',
    component: AdminLayoutComponent,
    children: [
      {
        path: '',
        redirectTo: 'users',
        pathMatch: 'full'
      },

      {
        path: 'agencies',
        loadChildren: () =>
          import('./agencies/agencies.module').then(
            (m) => m.AgenciesModule
          ),
      },
      {
        path: 'users',
        loadChildren: () =>
          import('./admin/admin.module').then(
            (m) => m.AdminModule
          ),
      },
    ],
  },
  {
    path: 'provider-data',
    component: HhaLayoutComponent,
    children: [

      {
        path: '',
        redirectTo: 'hha-caregivers',
        pathMatch: 'full'
      },
      {
        path: '',
        loadChildren: () =>
          import('./hha-caregivers/hha-caregivers.module').then(
            (m) => m.HhaCaregiversModule
          ),

      },
    ]
  },
  {
    path: 'auth',
    loadChildren: () =>
      import('./auth/auth.module').then(
        (m) => m.AuthModule),
  },

];


@NgModule({

export class AppRoutingModule {

正如控制台中的错误所示，您正在尝试读取空对象的 prpoerty UID，但我在您的代码中看不到 UID prpoerty，也许在另一个文件中？
