Angular2：“...”的路由生成器未包含在传递的参数中

Question

我在使用 Angular2 路由时遇到问题。我有几层嵌套。这是我的设置：我为未经身份验证的用户提供顶级路由。登录后，他们位于 /my 路线下。在那个级别，他们有一个仪表板，可以将他们带到 /my/projects/ 级别。 projects 下的路由需要一个 ID。设置的详细信息如下。这是顶级 AppComponent:

 @RouteConfig([
  {path: '/home', name:'Home', component: HomeComponent, useAsDefault: true},
  {path: '/login', name: 'Login', component: LoginComponent},
  {path: '/signup', name: 'SignUp', component:SignUpComponent},
  {path: '/my/...', name: 'MyApp', component: MyAppComponent}
])
export class AppComponent {
  constructor(private router: Router) {

  }

一旦通过身份验证，用户将转到 MyAppComponent，其设置如下：

 @RouteConfig([
  {path:'/dashboard', name: 'MyDashboard', component: DashboardComponent, useAsDefault: true},
  {path: '/projects/...', name: 'MyProjects', component: ProjectRootComponent},
])

export class MyAppComponent {

  constructor(private router: Router) {
  }
}

仪表板组件：

export class DashboardComponent {
  public projects: Array<Project>;
  public loaded: boolean;
  public loadError: boolean;

  constructor(private _service: ProjectService, private router:Router) {
    this.projects = [];
    this.loaded = false;
  }

  ngOnInit() {
    console.log('Dashboard component initialized');
    this._service.getUserProjects()
    .then(projects => {
      this.loaded = true;
      this.projects = projects;
    },
    error => {
      this.loaded = true;
      this.loadError = error;
    });
  }

  selectProject(project: Project) {
    // this.router.navigateByUrl('/my/projects/' + project.id); // Tried this approach as well with the same error
    this.router.parent.navigate(['MyApp', 'MyProjects', {id: project.id}]);
  }

在 DashboardComponent 上，我加载了一个项目列表。当我单击一个项目时，将调用 selectProject(project) 方法，该方法应该导航到该项目页面。项目 id 作为参数传入。 MyProjects 路由需要一个 id，设置如下：

    @RouteConfig ([
  {path: '/:id', name: 'ProjectHome', component: ProjectHomeComponent, useAsDefault: true},
  {path: '/:id/details', name: 'ProjectDetails', component: ProjectDetailsComponent },
])

export class ProjectRootComponent implements OnInit {

  id: string;
  constructor(private router: Router, private routeParams: RouteParams, private projectService: ProjectService) {
  }

  ngOnInit() {
    this.id = this.routeParams.get('id');

    console.log('Project Component Initialized with id: ' + this.id);
  }

  createProject() {

  }
}

当仪表板上的 selectProject(project) 被调用时，我收到错误：ORIGINAL EXCEPTION: Route generator for 'id' was not included in parameters passed.

我还尝试使用这两种方法直接导航到项目详细信息：

this.router.parent.navigate(['MyApp', 'MyProjects', {id: project.id}, 'ProjectDetails']

和

 this.router.parent.navigate(['MyApp', 'MyProjects', 'ProjectDetails', {id: project.id}]

两者都会产生与上述相同的错误。

注意：这与之前问的 this question 类似，但我的路线已经按照该问题的答案中的建议设置。

我认为您遇到了路线查找问题，因为您是从子路线导航的。来自 RouterLink docs（linkParams 应该相同）：

The first route name should be prepended with /, ./, or ../. If the route begins with /, the router will look up the route from the root of the app. If the route begins with ./, the router will instead look in the current component's children for the route. And if the route begins with ../, the router will look at the current component's parent.

我相信这应该有效：

this.router.navigate(['/MyApp', 'MyProjects', 'ProjectDetails', {id: project.id}]

或从仪表板：

this.router.navigate(['./MyProjects', 'ProjectDetails', {id: project.id}]
