Question

我似乎无法想出这个。我以用户身份登录。我已经缩小了一点，但由于Angular Material，我依赖于BrowserAnimationsModule作为依赖。但是如果我删除导入它似乎没有这个问题并正常加载。

这是我的函数调用我将在收到响应时导航到新路径。

login() {
  this.authService.login()
  .then((res) => {
      this.router.navigate(['home'])
    })
  .catch((err) => console.log(err));
}

就像这样，但我无法弄清楚导致登录页面仍然出现在我的主组件下面的原因。 app.component.html看起来像这样，只是拿着路由器插座。

<router-outlet></router-outlet>

这是我的app.routing.ts文件

import { Routes, RouterModule } from '@angular/router';

import {
  LoginComponent,
  HomeComponent
} from './_components/index';

import { AuthGuard } from './_guards/auth.guard';

let appRoutes: Routes = [
  {
    path: 'login',
    component: LoginComponent
  },
  {
    path: 'home',
    canActivate: [AuthGuard],
    component: HomeComponent
  }
];

export const AppRoutes = RouterModule.forRoot(appRoutes);

虽然我自己无法理解这种追踪，或者发现了一些事情。我认为帮助诊断可能会有所帮助。我仍然认为这与材料所依赖的@ angular / animations有某种关系。

通过明确告诉NgZone运行，我得到了这个。看来Angular在捕获未处理的异常时遇到了问题

login() {
    this.auth.login()
    .then((res) => {
      this.zone.run(() => { this.router.navigate(['/home']); });
      })
    .catch((err) => console.log(err));
}

由于BrowserAnimationsModule
