我只是抓住Angular RouterModule,请耐心等待。
我已经设置了一个应用程序组件,其中包含允许用户登录和注册的按钮。但是当单击链接时,Angular会返回404;我无法理解为什么,我已经效仿了这个例子。
任何人都不知道我在哪里可以找到这个问题吗?
我有两个重要的模块:
// app.module.ts
import { BrowserModule } from '@angular/platform-browser';
import { HttpClientModule } from '@angular/common/http';
import { AppComponent } from './app.component';
import { PageNotFoundComponent } from './page-not-found/page-not-found.component';
import { RouterModule, Routes } from '@angular/router';
import { UserModule } from './user/user.module';
import { AuthenticationService } from './user/authentication.service';
import { AppRoutingModule } from './app-routing/app-routing.module';
import { EntryModule } from './entry/entry.module.ts';
const appRoutes: Routes = [
{ path: 'entries', component: EntryListComponent },
{ path: '', redirectTo: 'entries', pathMatch: 'full'}, // empty
{ path: '**', component: PageNotFoundComponent} // catch-all
];
@NgModule({
declarations: [
AppComponent,
PageNotFoundComponent
],
imports: [
BrowserModule,
UserModule,
AppRoutingModule,
RouterModule.forRoot(appRoutes),
HttpClientModule
],
providers: [
AuthenticationService
],
bootstrap: [AppComponent]
})
export class AppModule { }
// app.component.html(摘录)
<button *ngIf='!(currentUser | async) else ng-hide'class="ui button" title="Login">
<a class="item" routerLinkActive='active' routerLink="/login">
<i class="large black user icon"></i>
</a>
</button>
<button *ngIf='!(currentUser | async) else ng-hide' class="ui button" title="Register">
<a class="item" routerLinkActive='active' routerLink="/register">
<i class="large black user plus icon"></i>
</a>
// app-routing.module.ts
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterModule, Routes } from '@angular/router';
import { PageNotFoundComponent } from '../page-not-found/page-not-found.component';
import { SelectivePreloadStrategy } from './SelectivePreloadStrategy';
import { AuthGuardService } from '../user/auth-guard.service';
const appRoutes: Routes = [
{
path: 'entry',
canActivate: [ AuthGuardService ],
loadChildren: 'app/entry/entry.module#EntryModule' // <<< THIS IS IMPORTANT
},
{ path: '', redirectTo: 'entry', pathMatch: 'full'},
{ path: '**', component: PageNotFoundComponent}
];
@NgModule({
imports: [
CommonModule,
RouterModule.forRoot(appRoutes, { preloadingStrategy: SelectivePreloadStrategy })
],
declarations: [],
exports: [
RouterModule
]
})
export class AppRoutingModule { }
我不太确定问题是否存在于任何这些文件中,但可以找到Github回购here。
非常感谢任何帮助......
