防止在角度4中在浏览器中重定向写入URL

Posted 2021-04-24

我无法将用户踢到根网址

以下代码无效

路由器

export const RouteDefinitions: Routes = [

  {
    path: 'home',
    component: LandingPageComponent,
    canActivate: [AuthGuard]
  },
  {
    path: 'holmes',
    component: HolmesMasterComponent,
    canActivate: [AuthGuard],
    children: [{
      path: 'unauthorized',
      component: UnauthorizedComponent
    }]
  },

  {
    path: 'his',
    component: MasterComponent,
    canActivate: [AuthGuard],
    children: [{
        path: '',
        component: HisParentComponent
      },
      {
        path: 'group',
        component: GroupListComponent
      },
      {
        path: 'test',
        component: TestComponent
      },
    ]
  },
  {
    path: '**',
    component: LandingPageComponent,
    canActivate: [AuthGuard]
  }
];

我需要做些什么来改变它？

auth.guard.ts

import { Injectable } from '@angular/core';
import { Router, CanActivate, ActivatedRouteSnapshot, RouterStateSnapshot } from '@angular/router';
 import{ AuthService} from '../Services/auth.service'
import { Appconfig } from '../Content/Config/AppConfig';
import { Observable } from 'rxjs/Observable';


@Injectable()
export class AuthGuard implements CanActivate {

    UnauthorizedCode:number=401;
    constructor(private router: Router,private  authService:AuthService ) { }

    canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<boolean> | Promise<boolean> | boolean {    

     this.someservice.authenticateUserLocalDB();
        return true;

    }
}

请帮我

菜单重定向

  <aside id="sidebar" class="main-sidebar">
      <section class="sidebar">
          <ul class="sidebar-menu" id="sidemenu">

                      </li>

              </li>

答案

也许尝试使用redirectTo：

{
    path: 'home',
    component: LandingPageComponent,
    canActivate: [AuthGuard]
},
{
    path: '**',
    redirectTo: 'home'
}

编辑你也可能更喜欢使用空路径重定向：
