我目前已更新我的应用以使用ner Router。除了保护路线,我做了所有事情Angular 2 RC4路由器提供商

main。 TS是这样的:

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; 
    } 
} 

和应用路线,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) 
]; 

,我用旧的路由和一切罚款之前。现在,我得到了消息“没有AuthGuard的提供者!” althoug我将它包含在我的引导程序提供程序中。

在我里面的构造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,如果用户不是在它登陆重定向到登录页面,否则它重定向到主页和用户couldn” t直到他没有登录才看到家。我在哪里我错了,为什么我得到这个错误,因为我包含供应商在我的引导方法作为提供者?

第一次发生这种情况,我,这个问题实际上回答了我的问题。感谢您的'auth.guard.ts'代码,我能够解决我有'canActiate(...)'的问题。我在构造函数中添加了'ActivatedRouteSnapshot',但看起来这是错误的方法,在'canActivate'上将它添加为默认参数。 –

取出'

canActivate: ['AuthGuard']}, 

canActivate: [AuthGuard]}, 

我也认为你应该添加pathMatch: 'full'

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

它现在有效!如此微不足道的错误,但我看不到。谢谢! :) –

为什么路径字段为空字符串? –

@王晓刚我刚刚从问题中复制了它。当没有给出路径时,该路线匹配。 –
