Question

刷新 http://localhost:4200/user/products/ $％7Buserid％7D 后，页面显示：

{ “成功”：真， “数据”：[]}

代码 src / app / product / product.module.ts

const routes = [
  {
    path: `user/products`, canActivate: [AuthGuard], component: UserProductsComponent 
  }, {
    path: `user/products/:id`, canActivate: [AuthGuard], component: UserProductsComponent
  }
];

@NgModule({
  imports: [
    CommonModule,
    FormsModule,
    HttpModule,
    ReactiveFormsModule,
    RouterModule.forChild(routes)
  ],
  declarations: [
    UserProductsComponent,
  ],
  exports: [
    UserProductsComponent,
    FormsModule]
})
export class ProductModule { }

代码 app.module.ts

const routes: Routes = [ 
   { path: '', component: NavbarComponent }
];

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    CoreModule,
    UserModule,
    ProductModule,
    RouterModule.forRoot(routes)
  ],
  providers: [AuthService, AuthGuard, UserService, ProductsService],
  bootstrap: [AppComponent]
})
export class AppModule { }

代码 auth.guard.ts

@Injectable()
export class AuthGuard implements CanActivate {

  constructor(private authService: AuthService, private router: Router) {}

  canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): boolean {
    return this.checkLoggedIn(state.url);
  }

  checkLoggedIn(url: string): boolean {
    if (this.authService.isLoggedIn_()) {
      return true;
    }       
    this.router.navigate(['/login']);
    return false;
  }
}

代码 src / app / product / user-products / user-products.ts：

ngOnInit() { 
   this.userObj = this.authService.currentUser;
   this.route.params.subscribe((params: any) => { 
      if (params.id) { 
          this.productid = params['_id'];       
          this.getProducts(this.userObj.userid); 
      } 
   }); 
}

如何更正user/products/:id页面的工作原理？这个页面的授权很糟糕吗？

如果您的路径确实是

然后你必须在user-products.ts中获得没有下划线的'id'。你当然不会使用userId获取产品，对吗？ ;）

user/products/:id

应该这样做。

刷新页面后：{“success”：true，“data”：[]}
