Angular 4 CanActivateChild不工作

Question

我试图使用CanActivateChild限制对我的路由系统的访问，但是当我试图阻止用户导航到一组子状态时，RouteGuard不起作用，只能在CanActivate上起作用。这是我的路由模块：

export const routes = [
    { path: "", redirectTo: "/signin", pathMatch: "full" },
    { path: "signin", component: SigninComponent },
    {
        path: "user",
        component: UserComponente,
        canActivate: [AuthGuard],
        canActivateChild: [AuthGuard],
        children: [
            { path: "profile", component: ProfileComponent, },
            { path: "address", component: AddressComponent, },
        ]
    },
    { path: "test", component: TestComponent, canActivate: [AuthGuard] },
];

在本例中，如果我尝试访问路由test，我可以看到AuthGuard正在执行，函数canActivate被调用。

但是，当我尝试导航到任何子路由(配置文件或地址)时，什么也没有发生。canActivate和canActivateChild都不会在AuthGuard上被调用。

这是我的防护文件：

import { Injectable } from '@angular/core';
import { CanActivate, CanActivateChild } from '@angular/router';
import { getString } from 'application-settings';
import { AppConfig } from './../config';

@Injectable()
export class AuthGuard implements CanActivate, CanActivateChild {
    constructor() { }

    canActivate() {
        console.log('canActivate executing.');

        if (!getString(AppConfig.authToken)) {
            alert('You need to be logged in.');
            return false;
        }
        return true;
    }

    canActivateChild() {
        console.log('canActivateChild executing.');
        return this.canActivate();
    }
}
