我目前已更新我的應用以使用ner Router。除了保護路線,我做了所有事情Angular 2 RC4路由器提供商

main。 TS是這樣的:

import {bootstrap} from '@angular/platform-browser-dynamic'; 
import {disableDeprecatedForms, provideForms} from '@angular/forms'; 
import {HTTP_PROVIDERS} from '@angular/http'; 
import 'rxjs/Rx'; 

import {AuthService} from './services/auth.service'; 
import {InsaService } from './services/insa.service'; 

import {AppComponent} from './app.component'; 

import {appStateProvider} from './providers/AppStateProvider' 
// Import configured routes 
import { APP_ROUTER_PROVIDERS } from './app.routes'; 
import {AuthGuard} from './services/auth.guard' 

bootstrap(AppComponent, [appStateProvider, APP_ROUTER_PROVIDERS, AuthService, AuthGuard, HTTP_PROVIDERS, InsaService ,disableDeprecatedForms(), provideForms()]) 
.catch(err => console.error(err)); 

我implementeed auth.guard.ts:

import { Injectable } from '@angular/core'; 
import { CanActivate, Router, ActivatedRouteSnapshot, RouterStateSnapshot } from '@angular/router'; 
import { AuthService } from './auth.service'; 
import {Observable} from 'rxjs/Observable'; 

@Injectable() 
export class AuthGuard implements CanActivate { 

    constructor(private _authService: AuthService, protected _router: Router) {} 

    canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Observable<boolean> | boolean { 

     if (state.url !== '/login' && !this._authService.isLoggedIn()) { 
      this._router.navigate(['/login']); 
      return false; 
     } 

     return true; 
    } 
} 

和應用路線,我有:

export const routes: RouterConfig = [ 
    { 
    path: '', 
    component: LoginComponent 
    }, 
    { path: 'login', component: LoginComponent }, 
    { path: 'home', component: HomeComponent, canActivate: ['AuthGuard']}, 
    { path: 'charts', component: ChartsComponent}, 
    { path: 'performance', component: PerformanceComponent}, 
    { path: 'news', component: NewsComponent}, 
    { path: 'transactions', component: TransactionsComponent}, 
    { path: 'portfolio', component: PortfolioComponent}, 
    { path: 'crossRates', component: CrossRatesComponent}, 
    { path: 'report', component: ReportComponent}, 
    { path: 'security', component: SecurityPricesComponent}, 
]; 

// Export routes 
export const APP_ROUTER_PROVIDERS = [ 
    provideRouter(routes) 
]; 

,我用舊的路由和一切罰款之前。現在,我得到了消息「沒有AuthGuard的提供者!」 althoug我將它包含在我的引導程序提供程序中。

在我裏面的構造app.component.ts我:

if (this._authService.isLoggedIn()) { 
     this._router.navigate(['/home']); 
    } 
    else { 
     this._router.navigate(['/login']); 
    } 

我更新路由器之前,如果用戶不是在它登陸重定向到登錄頁面,否則它重定向到主頁和用戶couldn」 t直到他沒有登錄纔看到家。我在哪裏我錯了,爲什麼我得到這個錯誤,因爲我包含供應商在我的引導方法作爲提供者?

第一次發生這種情況,我,這個問題實際上回答了我的問題。感謝您的'auth.guard.ts'代碼,我能夠解決我有'canActiate(...)'的問題。我在構造函數中添加了'ActivatedRouteSnapshot',但看起來這是錯誤的方法,在'canActivate'上將它添加爲默認參數。 –

取出'

canActivate: ['AuthGuard']}, 

canActivate: [AuthGuard]}, 

我也認爲你應該添加pathMatch: 'full'

{ 
    path: '', 
    component: LoginComponent, 
    pathMatch: 'full' 
    },

它現在有效!如此微不足道的錯誤,但我看不到。謝謝! :) –

爲什麼路徑字段爲空字符串? –

@王曉剛我剛剛從問題中複製了它。當沒有給出路徑時,該路線匹配。 –
