【问题描述】:
我的 Angular2/Meteor 应用程序出现问题。 我正在尝试从另一个组件重定向到一个组件,但它似乎没有第一次加载。但是,当我刷新页面时,它会完美加载。 当我调试时,我看到我的 html 视图没有显示任何变量,我的变量的值看起来正确,但它们没有显示在视图上。
这是我的卫兵:
import { CanActivate } from "@angular/router";
import { Meteor } from 'meteor/meteor';
import { Router } from '@angular/router';
import { Injectable } from '@angular/core';
@Injectable()
export class RouteGuardService implements CanActivate {
constructor(public router: Router) { }
canActivate() {
if (Meteor.userId() != undefined) {
return true;
}
else {
let link = ['accueil'];
this.router.navigate(link);
return false;
}
}
}
我的路由模块:
import { Route } from '@angular/router';
import {AccueilComponent} from "./pages/accueil/accueil.component";
import {ChannelsComponent} from "./pages/channel/channels.component";
import { RouteGuardService } from './services/routeGuard.service';
export const routes: Route[] = [
{ path: '', component: AccueilComponent },
{ path: 'accueil', component: AccueilComponent, pathMatch: 'full' },
{ path: 'channel', component: ChannelsComponent, canActivate: [RouteGuardService], pathMatch: 'full'},
];
我希望我的解释很清楚。不要犹豫,询问更多信息。 谢谢!
编辑: 我的 app.module:
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { RouterModule } from '@angular/router';
import { Ng2DragDropModule } from 'ng2-drag-drop';
import { AccountsModule } from 'angular2-meteor-accounts-ui';
import { AppComponent } from './app.component';
import { MomentModule } from "angular2-moment";
import { ModalModule } from 'ngx-modialog';
import { BootstrapModalModule } from 'ngx-modialog/plugins/bootstrap';
import { ChannelModal } from './pages/channel/channel_search/channel-list.modal';
import { RouteGuardService } from './services/routeGuard.service';
import { AccueilComponent } from "./pages/accueil/accueil.component";
import { LOGIN_DECLARATIONS } from './pages/login';
import { CHANNEL_DECLARATIONS } from './pages/channel';
import { routes } from './app.routes';
@NgModule({
imports: [
RouterModule.forRoot(routes),
Ng2DragDropModule.forRoot(),
ModalModule.forRoot(),
BrowserModule,
AccountsModule,
FormsModule,
ReactiveFormsModule,
MomentModule,
BootstrapModalModule,
],
declarations: [
AppComponent,
AccueilComponent,
...LOGIN_DECLARATIONS,
...CHANNEL_DECLARATIONS,
ChannelModal
],
bootstrap: [
AppComponent
],
entryComponents: [
ChannelModal
],
providers:[
RouteGuardService
]
})
export class AppModule { }
【问题讨论】:
-
尝试在这样的路由前使用'/' this.router.navigate('/accueil');
-
我试过了,但是没用 :(
-
尝试这样使用 this.router.navigate(['/accueil]);
-
也试过了,不行:(
-
能发一下app.module代码吗
