具有相同路径的 Angular 2 模块

有 2 个模块具有相同的路径但具有不同的模板（main 和 auth）。模块加载关于用户是否通过身份验证是必要的。不幸的是，它不是这样工作的。

有代码

app-routing.module.ts

import { NgModule } from '@angular/core';
import { PreloadAllModules, RouterModule, Routes } from '@angular/router';
import { AuthService } from './core/services/auth.service';

var authService = new AuthService()

const routes: Routes = [
  {path: '', loadChildren:() => authService.isAuth ?    import('./modules/main/main.module').then(m => m.MainModule) : import('./modules/auth/auth.module').then(m => m.AuthModule)}
];

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

main.router.ts

import { NgModule } from '@angular/core';
...

const routes = [
    {path: '', component: MainComponent, children: [
        {path: '', redirectTo: 'dashboard', pathMatch: 'full'},
        {path: 'dashboard', component: MainPageComponent},
        {path: 'payments', component: PaymentPageComponent},
        {path: 'profile', component: ProfileComponent},
        {path: 'cards', component: CardsComponent},
        {path: 'accounts', component: AccountsComponent},
        {path: 'loans', component: LoansComponent},
        {path: 'deposits', component: DepositsComponent},
        {path: 'extracts-and-reports', component: ExtractsAndReportsComponent},
        {path: 'payroll', component: PayrollComponent},
        {path: 'settings', component: SettingsComponent},
        {path: 'confirm', component: PaymentAccessComponent},
        {path: 'mailbox', component: MailboxComponent},
        {path: '**', component: PageNotFoundComponent}
    ]}
]

@NgModule({
    imports: [
        RouterModule.forChild(routes)
    ],
    exports: [
        RouterModule
    ],
    declarations: [],
    providers: [],
})
export class MainRouter { }

auth.router.ts

import { NgModule } from '@angular/core';
...

const routes = [
    {path: '', component: AuthComponent, children: [
        {path: '', redirectTo: 'login', pathMatch: 'full'},
        {path: 'login', component: LoginComponent},
        {path: 'register', component: RegisterComponent}
    ]}
]

@NgModule({
    imports: [
        RouterModule.forChild(routes)
    ],
    exports: [
        RouterModule
    ],
    declarations: [],
    providers: [],
})
export class AuthRouter { }
