Angular 4 Routing - 所有路由都被重定向到Default Route

Question

我為我的angular 4應用程序設置了一個簡單的路由，包括使用Tetradata Covalent和Angular Material創建的sidemenu，我使用這個Angular 2/4身份驗證教程來處理登錄，但所有子路由器鏈接都重定向到默認頁面（儀表板）。 任何幫助或建議將受到高度贊賞。

app.routing.ts

export const APP_ROUTES: Routes = [
  {path: 'login', component: HomeComponent},
  { path: '', redirectTo: 'mainpage', pathMatch: 'full' },
  { path: '**', redirectTo: 'mainpage' },
  {
    path: 'mainpage',
    component: MainPageComponent,
    canActivate:[AuthGuard],
    children: [
      {path: 'order', component: OrderComponent},
      {path: 'dashboard', component: DashboardComponent},
      {path: 'stock', component: StockComponent},
      {path: 'Report/sales', component: SalesComponent},
      {path: '', redirectTo: 'dashboard', pathMatch: 'full'}
      {path: '**', redirectTo: 'dashboard', pathMatch: 'full'}
    ]
  }
];

page.component.html

<td-layout>
  <td-navigation-drawer flex sidenavTitle="EzyAgric" logo="assets:logo" name="Akorion" email="info.akorion.com">
<md-nav-list>
      <a md-list-item [routerLink]="['dashboard']">
        <md-icon>dashboard</md-icon>
        Dashboard</a>
      <md-divider></md-divider>
      <h3 md-subheader>Orders</h3>
      <a md-list-item [routerLink]="['stock']">
        <md-icon>archive</md-icon>
        Stock
      </a>
      <a md-list-item [routerLink]="['order']">
        <md-icon>shopping_cart</md-icon>
        Received Orders
      </a>
  </td-navigation-drawer>
  <td-layout-nav [toolbarTitle]="getTitle()" >
    <div class="example-scrolling-content">
      <router-outlet></router-outlet>
    </div>
  </td-layout-nav>
</td-layout>

AuthGuard.ts

@Injectable()
export class AuthGuard implements CanActivate {
  constructor(private router: Router) { }

  canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot) {
    if (localStorage.getItem('currentUser')) {
      // logged in so return true
      return true;
    }

    // not logged in so redirect to login page with the return url
    this.router.navigate(['/login'], { queryParams: { returnUrl: state.url }});
    return false;
  }
}

在您定義路線的app.routing.ts中，在定義了所有路線后，將通配符行移至末尾。

app.routing.ts

export const APP_ROUTES: Routes = [
  {path: 'login', component: HomeComponent},
  { path: '', redirectTo: 'mainpage', pathMatch: 'full' },
  {
    path: 'mainpage',
    component: MainPageComponent,
    canActivate:[AuthGuard],
    children: [
      {path: 'order', component: OrderComponent},
      {path: 'dashboard', component: DashboardComponent},
      {path: 'stock', component: StockComponent},
      {path: 'Report/sales', component: SalesComponent},
      {path: '', redirectTo: 'dashboard', pathMatch: 'full'}
      {path: '**', redirectTo: 'dashboard', pathMatch: 'full'}
    ]
  },
  { path: '**', redirectTo: 'mainpage' } // this needs to be after other routes
];

由於它是一個外卡路線，因為路線順序很重要，因此在到達任何其他路線之前，角度將會擊中此路線。

您必須更改類似的代碼：

export const APP_ROUTES: Routes = [
  { path: '', redirectTo: 'mainpage', pathMatch: 'full' },
  { path: 'login', component: HomeComponent },  
  {
    path: 'mainpage',
    component: MainPageComponent,
    canActivate:[AuthGuard],
    children: [
      {path: 'order', component: OrderComponent},
      {path: 'dashboard', component: DashboardComponent},
      {path: 'stock', component: StockComponent},
      {path: 'Report/sales', component: SalesComponent}
    ]
  },
  { path: '**', redirectTo: 'mainpage' }
];
