Question

我有以下路线规则：

CREATE OR REPLACE TRIGGER FECHASALIDA
BEFORE INSERT ON EXPEDIENTES
FOR EACH ROW
BEGIN
IF (:NEW.FECHAINGRESO>:NEW.FECHASALIDA)
THEN RAISE_APPLICATION_ERROR (-20600,:NEW.FECHASALIDA||'No se puede dar una fecha de salida anterior a la del ingreso');
END IF;
END;

如何禁止使用开放的特定路径路径，如：

 path: 'school', component: ShellComponent, canActivate: [AuthenticationGuard],
    children: [
      {path: 'education/documents', component: DocumentsComponent}]

如果使用角色管理员或其他？

使用像{path: 'education/documents', component: DocumentsComponent}]

这样的自定义中间件是否相同？

创建Gaurd文件，您可以根据自己的要求进行更新

import {Injectable} from '@angular/core';
import {CanActivate, ActivatedRouteSnapshot, RouterStateSnapshot} from '@angular/router';
import {Observable} from 'rxjs';

@Injectable({
     providedIn: 'root'
})

export class AuthGuard implements CanActivate {

constructor(private helper: HelperService, private auth: AuthService) { }

canActivate(
    next: ActivatedRouteSnapshot,
    state: RouterStateSnapshot): Observable<boolean> | Promise<boolean> | boolean {

    if (this.auth.isLoggedIn) {
        // logged in so return true
        return true;
    }
    // not logged in so redirect to login page with the return url
    this.helper.redirect('/');
    return false;
    }
}

在路线文件中使用保护：

{path: 'account',component: AccountComponent,canActivate: [AuthGuard]},
children: [
{
    path: 'account',
    component: AccountComponent,
    canActivate: [AuthGuard]
}
]

如何在Angular中保护路径？
