这是一个初学角度问题.

我的Angular应用程序包含多个功能模块.我通过从angular-cli生成guard来使用authguard,然后在我的app-routing模块中使用CanActivate,如下所示:

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { AuthGuard } from './auth.guard';

const routes: Routes = [
{path:'login',loadChildren:'./login/login.module#LoginModule',canActivate: 
[AuthGuard]},
{path:'home', loadChildren:'./user/user.module#UserModule',canActivate: 
[AuthGuard]},
{path:'cart', 
loadChildren:'./cart/cart.module#CartModule',canActivate:[AuthGuard]},
 {path:'customer',loadChildren:'./customer/customer.module#CustomerModule',canActivate:[AuthGuard]}
];

@NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule]
})
export class AppRoutingModule { }

在我的身份验证中,我写了条件以防止用户访问未经授权的路由:

import { Injectable } from '@angular/core';
import { CanActivate, ActivatedRouteSnapshot, RouterStateSnapshot } from 
'@angular/router';
import { Observable } from 'rxjs/Observable';
import { Router } from '@angular/router';

@Injectable()
export class AuthGuard implements CanActivate { …
