如何将参数传递给canActivate的构造函数?

本文介绍了如何将参数传递给canActivate的构造函数?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我具有以下路线路径:

{
    path: 'teacher',
    component: DashboardTeacher, canActivate: [AccessGuardTeacher('Teacher')]
}

如您所见，我试图在类 AccessGuardTeacher 中传递参数'Teacher':

As you can see I tried to pass parameter 'Teacher' in class AccessGuardTeacher:

export class AccessGuardTeacher implements CanActivate {

  constructor(private role: string) {
  }
}

该怎么做对呢?

推荐答案

您的路线应配置为:

{
   path: 'teacher',
   component: DashboardTeacherComponent,
   canActivate: [AccessGuardTeacher],
   data: {
            role: 'teacher'
         }
}

在CanActivate Guard中获取路线数据

Get your route data in your CanActivate Guard

export class AccessGuardTeacher implements CanActivate {

     constructor() {
     }

    canActivate(route: ActivatedRouteSnapshot): boolean {

        const role = route.data.role;
        return true; //based on your condition
    }
}
