[英]Angular 8 optional url parameters
import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { LayoutComponent } from './layouts/layout.component';
const routes: Routes = [
{
path: '',
component: LayoutComponent,
children: [
{
path: ':id',
loadChildren: './layouts/layout.module#LayoutModule'
}
]
},
{ /* THIS BELOW BLOCK WORKS */
path: '',
component: LayoutComponent,
children: [
{
path: '',
loadChildren: './layouts/layout.module#LayoutModule'
}
]
}
];
@NgModule({
imports: [RouterModule.forRoot(routes, {
scrollPositionRestoration: 'enabled'
})],
exports: [RouterModule]
})
export class AppRoutingModule { }
我試圖讓 2 個不同的 url 集具有相同的布局集。 so my first url will be like http://localhost:4200/account - this works fine http://localhost:4200/20/account - this is my 2nd url and this doesn't work and the error message is
core.js:5882 ERROR Error: Uncaught (in promise): Error: Cannot match any routes. URL Segment: '20/account'
我不確定我哪里出錯了,任何人都可以幫助解決這個問題嗎?
您可以刪除 path:':id' 並在承包商中獲取參數:
public constructor(
private route: ActivatedRoute,
private router: Router,
injector: Injector
) {
super(injector);
this.route.params.subscribe((p) => {
this.stateIdFilter = [Number.parseInt(p.id)];
if (p.id) {
this.getData();
}
}); }
