我的Angular应用程序正在加载一个组件两次。最初,我在我的组件模板中有<router-outlet></router-outlet>
,它工作正常,但仍然给我这些错误:
core.umd.js:3257 EXCEPTION: Uncaught (in promise): Error: Cannot find primary outlet to load 'AppComponent'
core.umd.js:3262 ORIGINAL STACKTRACE:
core.umd.js:3263 Error: Uncaught (in promise): Error: Cannot find primary outlet to load 'AppComponent'
zone.js:355 Unhandled Promise rejection: Cannot find primary outlet to load 'AppComponent' ; Zone: angular ; Task: Promise.then ; Value: Error: Cannot find primary outlet to load 'AppComponent'(…) Error: Cannot find primary outlet to load 'AppComponent'
zone.js:357 Error: Uncaught (in promise): Error: Cannot find primary outlet to load 'AppComponent'
要解决这些错误,我将<router-outlet></router-outlet>
添加到了我的模板中。但现在我的应用程序正在加载我的组件两次。
app.component.ts
import { Component } from '@angular/core';
@Component({
moduleId: module.id
selector:'body',
templateUrl: 'app.component.html',
styleUrls: ['app.component.css']
})
export class AppComponent {
title = 'Doctor Application';
}
应用-routing.module.ts
import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { AppComponent } from './app.component';
const routes: Routes = [
{ path: '', component: AppComponent },
];
@NgModule({
imports: [ RouterModule.forRoot(routes) ],
exports: [ RouterModule ]
})
export class AppRoutingModule {}
app.component.html
<h1>{{title}}</h1>
<router-outlet></router-outlet>
答案 0 :(得分:2)
AppComponent
不应该成为路由的一部分。它曾用于引导。这就是错误的含义。您正在尝试将AppComponent
添加到路由中,但它没有<router-outlet>
,因为它是顶级组件。
