phpclass User extends Model {

    public function role()
    {
        return $this->hasOne('App\Role','user_id', 'id');
    }

}
class Role extends Model {

    public function permission()
    {
        return $this->hasMany('App\Permission','role_id', 'role_id');
    }

}
$permissions = User::find(Auth::user()->id)->Role()->permission();//未测试，不知是否可行
