如果编译和启动服务器后,Angular页面为空,可能有以下几种原因和解决方法:
// app.module.ts
import { RouterModule, Routes } from '@angular/router';
const routes: Routes = [
{ path: '', redirectTo: 'home', pathMatch: 'full' },
{ path: 'home', component: HomeComponent },
{ path: 'about', component: AboutComponent },
];
@NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule]
})
export class AppRoutingModule { }
// app.component.html
// home.component.ts
import { Component } from '@angular/core';
@Component({
selector: 'app-home',
templateUrl: './home.component.html',
styleUrls: ['./home.component.css']
})
export class HomeComponent { }
// home.component.html
Welcome to Home Page!
// home.component.ts
import { Component, OnInit } from '@angular/core';
import { HttpClient } from '@angular/common/http';
@Component({
selector: 'app-home',
templateUrl: './home.component.html',
styleUrls: ['./home.component.css']
})
export class HomeComponent implements OnInit {
data: any;
constructor(private http: HttpClient) { }
ngOnInit(): void {
this.http.get('https://api.example.com/data').subscribe((response: any) => {
this.data = response;
});
}
}
// home.component.html
Welcome to Home Page!
Data: {{ data }}
通过以上方法检查和解决问题,你应该能够找到并修复导致Angular页面为空的问题。
