Angular 2:'...'的路由生成器未包含在传递的参数中

Question

所以我在AuthenticationService中有以下代码.检查登录凭据后,用户将被重定向到其配置文件:

authentication.service.ts:

redirectUser(username:string):void {
  // Redirect user to profile on successful login
  this.router.navigate(['../Profile/Feed', {username: username}]);
}

这一切都很好,但自从我在里面引入了一些子路由后ProfileComponent,我遇到了一些错误.首先,这是我的AppComponent与RouteConfig:

app.ts:

import {Component, ViewEncapsulation} from 'angular2/core';
import {RouteConfig,ROUTER_DIRECTIVES} from 'angular2/router';
import {HTTP_PROVIDERS} from 'angular2/http';

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

import {AuthenticationService} from '../../services/authentication.service';
import {LoginComponent} from '../login/login';
import {ProfileComponent} from '../profile/profile';
import {ProfileService} from '../../services/profile.service';

@Component({
  selector:      'app',
  viewProviders: [AuthenticationService, ProfileService, HTTP_PROVIDERS],
  encapsulation: ViewEncapsulation.None,
  directives:    [
    ROUTER_DIRECTIVES
  ],
  templateUrl:   './components/app/app.html'
})

@RouteConfig([
  {path: '/', component: HomeComponent, as: 'Home'},
  {path: '/inloggen', component: LoginComponent, as: 'Login'},
  {path: '/profile/:username/...', component: ProfileComponent, as: 'Profile'}
])

export class AppComponent {
  ...
}

如您所见,在ProfileComponent中定义了一些新路由.如下图所示:

ProfileComponent.ts:

import {Component, OnInit} from 'angular2/core';
import {RouteConfig,ROUTER_DIRECTIVES, RouteParams, RouterLink, RouterOutlet} from 'angular2/router';
import {ProfileService} from '../../services/profile.service';
import {PROFILE_IMAGES} from '../../constants/constants';
import {WorkoutsComponent} from '../workouts/workouts';
import {FeedComponent} from '../feed/feed';

interface IProfileVM {
  username: string;
  profileUser: Object;
  getProfileData(username:string): void;
}

@Component({
  selector:    'profile',
  templateUrl: './components/profile/profile.html',
  directives:  [RouterOutlet, RouterLink],
  providers:   [ProfileService]
})

@RouteConfig([
  {path: '/nieuwsfeed', component: FeedComponent, as: 'Feed'},
  {path: '/workouts', component: WorkoutsComponent, as: 'Workouts'}
])

export class ProfileComponent implements OnInit, IProfileVM {

  public username:string;
  public profileUser:any;

  constructor(private _profileService:ProfileService,
              private _params:RouteParams) {
    this.username = this._params.get('username');
  }

  ngOnInit() {
    this.getProfileData(this.username);
  }

  getProfileData(username) {
    // Do stuff..
  }
}

所以这里的问题是,在我在ProfileComponent中引入一些子路由之前,一切正常.用户被重定向,用户名出现在URL中,一切正常.但是因为我添加了这些子路由,我收到以下错误:

"Route generator for 'username' was not included in parameters passed."

很高兴有人可以帮助我!提前致谢!

我认为您最好在路线定义中将嵌套配置文件组件向上移动一个级别。任意值username对配置文件组件路由没有影响。此外，子路由中实际上需要该值，这是应该定义它的位置。

因此父组件路由将从:username配置文件路由中丢失，看起来像这样：

@RouteConfig([
  {path: '/', component: HomeComponent, as: 'Home'},
  {path: '/inloggen', component: LoginComponent, as: 'Login'},
  {path: '/profile/...', component: ProfileComponent, as: 'Profile'}
])

相反，您的配置文件组件将定义:username路由参数：

@RouteConfig([
  {path: '/:username/nieuwsfeed', component: FeedComponent, as: 'Feed'},
  {path: '/:username/workouts', component: WorkoutsComponent, as: 'Workouts'}
])

这种方法看起来更直观，并且会减少嵌套路由组件之间导航的问题。
