路由语法错误区域符号错误角度 2

Question

我在尝试路由我的应用时遇到以下错误：

metadata_resolver.js:972 Uncaught 
SyntaxError {__zone_symbol__error: Error: Unexpected value '[object Object]' imported by the module 'AppModule' at SyntaxError.Zone……}

app.modules.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';

import { AppComponent } from './app.component';
import { EventListComponent } from './event-list/event-list.component';
import { EventThumbnailComponent } from './event-thumbnail/event-thumbnail.component';
import { EventsService } from './shared/events.service';
import { EventDetailsComponent } from './event-details/event-details.component';
import { RouterModule, Routes } from '@angular/router';
 import { appRoutes } from './routes';

@NgModule({
  declarations: [
    AppComponent,
    EventListComponent,
    EventThumbnailComponent,
    EventDetailsComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    appRoutes
  ],
  providers: [EventsService],
  bootstrap: [AppComponent]
})
export class AppModule { }

routes.ts

import { Routes,RouterModule } from '@angular/router';
import { ModuleWithProviders } from '@angular/core';
import { EventListComponent } from './event-list/event-list.component';
import { EventDetailsComponent } from './event-details/event-details.component';

export const router: appRoutes=[
   { path:'events', component :EventListComponent },
    { path:'events/:id', component :EventDetailsComponent },
    { path: '' , redirectsTo : '/events' , pathMatch: 'full' }
    ];

    export const router: ModuleWithProviders= RouterModule.forRoot(router);

我不明白为什么会出现上述错误以及 Zone_symbol_error 的含义。我想知道这意味着什么以及如何解决上述代码。

您必须导入已配置的 router = RouterModule.forRoot(appRoutes) 而不是其配置 appRoutes：

在您的 routes.ts 文件中：appRoutes :Routes 而不是 router: appRoutes 和 RouterModule.forRoot(appRoutes) 而不是 RouterModule.forRoot(router)

import { Routes,RouterModule } from '@angular/router';
import { ModuleWithProviders } from '@angular/core';
import { EventListComponent } from './event-list/event-list.component';
import { EventDetailsComponent } from './event-details/event-details.component';

export const  appRoutes :Routes=[
   { path:'events', component :EventListComponent },
    { path:'events/:id', component :EventDetailsComponent },
    { path: '' , redirectsTo : '/events' , pathMatch: 'full' }
    ];
    export const router: ModuleWithProviders= RouterModule.forRoot(appRoutes);

在 AppModule 中： router 而不是 appRoutes

import { router} from './routes';

@NgModule({
          declarations: [
            AppComponent,
            EventListComponent,
            EventThumbnailComponent,
            EventDetailsComponent
          ],
          imports: [
            BrowserModule,
            FormsModule,
            HttpModule,
            router
          ],
          providers: [EventsService],
          bootstrap: [AppComponent]
        })
        export class AppModule { }
