如何将参数传递给canActivate的构造函数? [英] How to pass parameters to constructor of canActivate?

问题描述

我有以下路线路径:

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

如您所见，我尝试在 AccessGuardTeacher 类中传递参数Teacher":

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

export class AccessGuardTeacher implements CanActivate {

  constructor(private role: string) {
  }
}

如何正确地做到这一点?

How to do that right?

推荐答案

你的路由应该这样配置:

Your route should be configured like:

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

在您的 CanActivate Guard 中获取您的路线数据

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
    }
}
