伙计们，我创建了两个组件，注册了路径，在 html 中注册，但是当您在控制台中单击 localhost 链接时，我进入一个空白页面，控制台中没有错误。

应用程序路由.module.ts

 import { NgModule } from '@angular/core';
 import { Routes, RouterModule } from '@angular/router';
 import { HomeComponent } from './home/home.component';
 import {RegistrationComponent} from './registration/registration.component';


const routes: Routes = [

 {path: 'home', component: HomeComponent},
 {path: '**', component: RegistrationComponent},
             ];

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

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { AppComponent } from './app.component';
import { RegistrationComponent } from './registration/registration.component';
import { HomeComponent } from './home/home.component';
import { AppRoutingModule } from './app-routing.module';
import {  HttpClientModule} from '@angular/common/http';

@NgModule({
  declarations: [
    AppComponent,
    RegistrationComponent,
    HomeComponent
  ],
  imports: [
    HttpClientModule,
    BrowserModule,
    AppRoutingModule,
    
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

注册.component.html

<p>registration works!</p>

<router-outlet></router-outlet>

伙计们安装了 13 版，从旧项目中拖出方法并subscribe划掉。

我知道它已经过时了，但我不知道如何改变它。告诉我在哪里挖。

registration = (Email: string, Username: string, Password: string) => {
    this.api.regUser(Email, Username, Password).subscribe(
        data => {
            this.router.navigate(['']);
        },
        error => {       
        }
    );
}
