Question

我已经从rc4更新了我们的项目 - ＆gt; RC5。这似乎工作正常。在执行此操作的同时，我还使用@angular/router-deprecated到@angular/router更新了我们的代码。

我的应用程序由2个部分组成，包括public和protected（所有用户都是公共的，受保护的只是管理员）。但是目前我只想让1条路线工作，然后我可以修复其他页面。

正如我所说，我已经更新了所有代码，我相信这是正确的，并且页面会加载，直到我将其添加到我的页面[routerLink]="['Home']"

如果我添加这个，那么我得到异常

ORIGINAL EXCEPTION：没有路由器的提供商！

如果我再次评论此行，则所有页面都可以正常加载。

以下是我的一些代码

app.module.ts

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

import { AppRoutes } from './app.routes';
import { AppComponent }  from './app.component';
import { PublicComponent } from './public.component';
//import { ProtectedComponent } from './protected.component';

// cms
import { HomeComponent } from './cms/home.component';

@NgModule({
    imports: [
        BrowserModule,
        FormsModule,
        HttpModule,
        RouterModule.forRoot(AppRoutes)
    ],
    declarations: [
        AppComponent,
        PublicComponent,
        HomeComponent
    ],
    bootstrap: [ AppComponent ]
})

export class AppModule { }

app.routes.ts

import { PublicComponent } from './public.component';
import { ProtectedComponent } from './protected.component';

// public
import { HomeComponent } from './cms/home.component';


export const AppRoutes = [
    {
        path: '',
        component: PublicComponent,
        children: [
            {
                path: '',
                redirectTo: 'home',
                pathMatch: 'full'
            },
            {
                path: 'home',
                component: HomeComponent
            },
        ]
    },
    // {
    //     path: 'admin/...',
    //     component: ProtectedComponent
    // }
];

app.component.ts

import { Component, ViewContainerRef } from '@angular/core';
import { ROUTER_DIRECTIVES } from '@angular/router'

@Component({
    selector: 'app-root',
    template: '<router-outlet></router-outlet>',
    directives: [ ROUTER_DIRECTIVES ]
})

export class AppComponent {
    viewContainerRef: ViewContainerRef;

    constructor(viewContainerRef: ViewContainerRef) {
        this.viewContainerRef = viewContainerRef;
    }
}

main.ts

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app.module';

platformBrowserDynamic().bootstrapModule(AppModule);

public.component.ts

import { Component, OnInit } from '@angular/core';
import { Router, ROUTER_DIRECTIVES } from '@angular/router';
import { CmsService } from './cms/cms.service';
import { ModuleService } from './module/module.service';
import { MenuItem } from './cms/models/menu-item';
import { Settings } from './cms/models/settings';
import { CollapseDirective } from 'ng2-bootstrap/components/collapse';
import { OffClickDirective } from './shared/offclick.directive';

@Component({
    selector: 'public',
    templateUrl: 'app/public.component.html',
    directives: [ ROUTER_DIRECTIVES, CollapseDirective, OffClickDirective ],
    providers: [ CmsService, ModuleService ]
})

export class PublicComponent {
    menu: MenuItem[];
    settings: Settings;
    isCollapsed: boolean = true;

    constructor(
        private cmsService: CmsService,
        private router: Router) {
    }
}

public.component.html

<div class="navbar navbar-dark bg-inverse navbar-fixed-top" role="navigation">
    <div class="container">
        <a class="navbar-brand" [routerLink]="['Home']">
            <span class="fa fa-home fa-2x" aria-hidden="true"></span>
            <span class="sr-only">Home</span>
        </a>
    </div>
</div>

我尝试将Router添加到public.component.ts中的提供者部分，但接下来又出现了另一个例外情况。

错误：无法解析路由器的所有参数：（？，？，？，？，？，？，？，？）

我显然错过了什么，但不知道是什么。任何帮助将不胜感激。

只是包装它有帮助，这里是我的package.json文件中的角度引用

"dependencies": {
    "@angular/common": "^2.0.0-rc.5",
    "@angular/compiler": "^2.0.0-rc.5",
    "@angular/core": "^2.0.0-rc.5",
    "@angular/forms": "^0.3.0",
    "@angular/http": "^2.0.0-rc.5",
    "@angular/platform-browser": "^2.0.0-rc.5",
    "@angular/platform-browser-dynamic": "^2.0.0-rc.5",
    "@angular/router": "^3.0.0-rc.1",
    "@angular/router-deprecated": "2.0.0-rc.2",
    "@angular/upgrade": "^2.0.0-rc.3"
}

从app.module.ts

调整app.module.ts

...
import { routing, appRoutingProviders } from './app.routing';
...

@NgModule({
  imports: [
    ...
    routing,
    ...
  ],
  ...
  providers: [
    ...
    appRoutingProviders,
    ...
  ],
  bootstrap: [AppComponent],
})
export class AppModule { }

调整app.routing.ts：

import { Routes, RouterModule } from '@angular/router';
import { DashboardComponent } from './dashboard/dashboard.component';
...
import { Http, HTTP_PROVIDERS } from '@angular/http';

const appRoutes: Routes = [
  { path: '', redirectTo: '/dashboard', pathMatch: 'full'},
  { path: 'dashboard', component: DashboardComponent, canActivate: [AuthGuard]},
  ...
  { path: '**', redirectTo: 'dashboard', pathMatch: 'full'}
];

export const appRoutingProviders: any[] = [
  ...
  Http,
  HTTP_PROVIDERS
];

export const routing = RouterModule.forRoot(appRoutes);

随处删除ROUTER_DIRECTIVES

Angular2更新为rc5和@ angular / router - ORIGINAL EXCEPTION：没有路由器
