@angular/cli项目构建--路由3

路由定位：

modifyUser(user) {
    this.router.navigate(['/auction/users', user.id]);
  }

路由定义：

{path: 'users/:id', component: UserModifyComponent, resolve: {user: UserResolve}},

UserResolve:

import {Injectable} from '@angular/core';
import {ActivatedRouteSnapshot, Resolve, RouterStateSnapshot} from '@angular/router';
import {User} from '../entity/user';
import {Observable} from 'rxjs/Observable';
import {UserService} from './user.service';

@Injectable()
export class UserResolve implements Resolve<User> {

  constructor(private userService: UserService) {
  }

  resolve(route: ActivatedRouteSnapshot,
          state: RouterStateSnapshot): Observable<User> | Promise<User> | User {
    return this.userService.getUserById(route.params.id);
  }
}

获取数据：

this.activatedRoute.data.subscribe((data) => this.model = data.user);

userService:

import {Injectable} from '@angular/core';
import {HttpClient, HttpParams} from '@angular/common/http';
import {Observable} from 'rxjs/Observable';

@Injectable()
export class UserService {

  constructor(private http: HttpClient) {
  }

  queryUsers(userName, fullName): Observable<any> {
    const params = new HttpParams()
      .set('userName', userName)
      .set('fullName', fullName);
    return this.http.get('/api/users', {params});
  }

  getUserById(id): Observable<any> {
    const url = '/api/users/' + id;
    return this.http.get(url);
  }

  deleteUser(id): Observable<any> {
    const url = '/api/users/' + id;
    return this.http.delete(url);
  }
}

参考路由配置思路（课件abstract路由可不需要path）：

const appRoutes: Routes = [
  {
    path: 'compose',
    component: ComposeMessageComponent,
    outlet: 'popup'
  },
  {
    path: 'admin',
    loadChildren: 'app/admin/admin.module#AdminModule',
    canLoad: [AuthGuard]
  },
  {
    path: 'crisis-center',
    loadChildren: 'app/crisis-center/crisis-center.module#CrisisCenterModule',
    data: { preload: true }
  },
  { path: '',   redirectTo: '/superheroes', pathMatch: 'full' },
  { path: '**', component: PageNotFoundComponent }
];

const adminRoutes: Routes = [
  {
    path: '',
    component: AdminComponent,
    canActivate: [AuthGuard],
    children: [
      {
        path: '',
        canActivateChild: [AuthGuard],
        children: [
          { path: 'crises', component: ManageCrisesComponent },
          { path: 'heroes', component: ManageHeroesComponent },
          { path: '', component: AdminDashboardComponent }
        ]
      }
    ]
  }
];

const crisisCenterRoutes: Routes = [
  {
    path: '',
    component: CrisisCenterComponent,
    children: [
      {
        path: '',
        component: CrisisListComponent,
        children: [
          {
            path: ':id',
            component: CrisisDetailComponent,
            canDeactivate: [CanDeactivateGuard],
            resolve: {
              crisis: CrisisDetailResolver
            }
          },
          {
            path: '',
            component: CrisisCenterHomeComponent
          }
        ]
      }
    ]
  }
];
