我正在制作一个Anuglar2 rc-4网络应用程序。我试图限制路线但是当我添加我的登录守卫时,它告诉我没有提供者。我的正常登录服务代码工作正常,就在我尝试添加登录保护和canActive路由时。有关如何解决此错误的任何想法?
routes.ts
import { RouterConfig } from '@angular/router';
import { Home } from './components/home/home';
import { Login } from './components/login/login';
import { DashBoard } from './components/dashboard/dashboard';
import { User } from './components/user/user';
import { Store } from './components/store/store';
import { LoggedInGuard } from './models/logged-in.guard.ts';
export const routes: RouterConfig = [
{ path: '', redirectTo: 'home', pathMatch: 'full' },
{ path: 'home', component: Home, canActivate: [LoggedInGuard] },
{ path: 'login', component: Login },
{ path: 'dashboard', component: DashBoard },
{ path: 'user', component: User },
{ path: 'store', component: Store },
{ path: '**', redirectTo: 'home' }
];
boot.ts
import { bootstrap } from '@angular/platform-browser-dynamic';
import { FormBuilder } from '@angular/common';
import { provideRouter } from '@angular/router';
import { HTTP_PROVIDERS, JSONP_PROVIDERS } from '@angular/http';
import { App } from './components/app/app';
import { routes } from './routes';
bootstrap(App, [
HTTP_PROVIDERS,
FormBuilder,
provideRouter(routes)
]);
登录in.guard.ts
import { Injectable } from '@angular/core';
import { Router, CanActivate } from '@angular/router';
import { LoginService } from '../services/login.service';
@Injectable()
export class LoggedInGuard implements CanActivate {
constructor(private ls: LoginService) {}
canActivate() {
return this.ls.isLoggedIn();
}
}
答案 0 :(得分:4)
您必须在应用程序引导功能
中注入LoggedInGuard
服务
bootstrap(App, [
HTTP_PROVIDERS,
FormBuilder,
provideRouter(routes),
LoggedInGuard // injected LoggedInGuard service provider here
]);
注意:这个答案对于当前的角度2更新版本(rc.6)不一样,升级时需要创建一个
NgModule
您要将所有依赖项包装在其中 单个地点,那个时间LoggedInGuard
将进入providers
选项 'NgModule
`
