点击“开始咨询”，显示咨询组件。然后随意切换“主页”和“股票信息”组件，老师的效果是咨询组件都还显示，我的却会消失；

老师点击“开始咨询”，url地址栏上会出现“（aux:consult）”,我的却没有。

代码如下：

<a [routerLink]="['/']">主页</a>
<a [routerLink]="['/stock', 1]">股票详情页</a>
<button (click)="toStockDetail()">股票详情</button>
<a [routerLink]="[{outlets: {aux: 'consult'}}]">开始咨询</a>
<a [routerLink]="[{outlets: {aux: null}}]">结束咨询</a>
<router-outlet></router-outlet>
<router-outlet name="aux"></router-outlet>

const routes: Routes = [
 { path: '', redirectTo: "/home", pathMatch: "full" },
 { path: 'home', component: HomeComponent },
 { path: 'consult', component: ConsultComponent, outlet: "aux"},
 { path: 'stock/:id', component: StockComponent, data: [{isPro: true}],
   children: [
     {path: '', component: BuyerListComponent},
     {path:'seller/:id', component: SellerListComponent, data: [{}]}
   ]
 },
 { path: '**', component: Code404Component }
];
