Vue.js在设置后获取会话

Question

我正在通过登录功能设置会话

<table style="width:100%">
    <tr>
        <th>Firstname</th>
        <th>Lastname</th>
        <th>Age</th>
    </tr>
    <tr (click)="show = !show">
        <td>Jill</td>
        <td>Smith</td>
        <td>50</td>
    </tr>
    <ng-container *ngIf="show">
        <tr class="box" [class.opened]="show">
            <td><div>Sam</div></td>
            <td><div>Sample</div></td>
            <td><div>35</div></td>
        </tr>
        <tr>
            <td><div>Piet</div></td>
            <td><div>Miller</div></td>
            <td><div>42</div></td>
        </tr>
    </ng-container>
    <tr>
        <td>Eve</td>
        <td>Jackson</td>
        <td>94</td>
    </tr>
</table>


<div style="margin-top: 20px" class="box" [class.opened]="show">
    Here the animation is working proper.  <br> <br>

</div>

我正在尝试在登录后加载的函数中检索它

 router.app.$session.set('user', user);

它给未定义。如果我将session.get函数延迟几秒钟，则可以获取该值。

除了延迟之外，还有其他获取会话值的方法吗？
