Angular2更新為rc5和@ angular / router-原始例外：沒有路由器的提供程序

Question

我已經從rc4-> rc5更新了我們的項目。 這似乎很好。 同時，我還使用@angular/router-deprecated了@angular/router來更新了我們的代碼。

我的應用程序由兩部分組成，公共部分和受保護部分（公共部分適用於所有用戶，受保護的部分僅適用於管理員）。 但目前我只想讓1條路線工作，然后我可以修復其他頁面。

正如我所說的，我已經更新了所有代碼，我認為這是正確的，並且頁面會一直加載，直到將其添加到我的頁面[routerLink]="['Home']"

如果我添加它，那么我會得到例外

原來的例外：沒有路由器的提供者！

如果我再次對此行發表評論，則所有頁面都可以正常加載。

這是我的一些代碼

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;
    }
}

主要

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>

我嘗試將Router添加到public.component.ts的providers部分，但是隨后出現另一個異常，如下所示。

錯誤：無法解析路由器的所有參數：（？，？，？，？，？，？，？，？）

我顯然錯過了一些東西，但不知道是什么。 任何幫助將非常感激。

只是包裹一下就可以了，這也是我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"
}

Answer 1

1. 從app.module.ts刪除routermodule

2. 調整app.module.ts

    ... import { routing, appRoutingProviders } from './app.routing'; ... @NgModule({ imports: [ ... routing, ... ], ... providers: [ ... appRoutingProviders, ... ], bootstrap: [AppComponent], }) export class AppModule { } 

3. 調整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); 

4. 隨處刪除ROUTER_DIRECTIVES
