一些逻辑代码

//获取菜单数据
    public static function get_menu($admin_id = null, $is_shop_admin = 10, $is_admin = 10) {
        if (empty($admin_id)) {
            throw new \Exception('管理员ID为空');
        }
        $field = array('id', 'parent_permission_id', 'permission_name', 'permission_url', 'small_icon_name');
        $result = AdminPermission::where('is_menu', 1)->orderBy('id', 'asc')->get($field)->toArray();
        if (empty($result)) {
            throw new \Exception('权限表为空');
        }
        //获取菜单树数组
        $menu = self::tree_menu($result);
        //店铺管理员或者超级管理员都有全部权限
        if ($is_shop_admin == 20 || $is_admin == 20) {
            return $menu;
        } else {
            return self::filter_menu($menu, $admin_id);
        }
    }

    //过滤菜单，只做到3层过滤，超过4层不支持，第三层作为具体菜单层
    public static function filter_menu($menu = null, $admin_id = null) {

        $permission = self::get_current_admin_permission($admin_id);
        if (empty($permission)) {
            //如果在 admin_group  admin_permission  admin 三表关系有问题查询会有问题，就会返回false，就直接返回空，没有菜单
            throw new \Exception('未获得当前用户权限菜单');
        }

        //先测试使用，可能存在bug
        foreach ($menu as $k => &$v) {
            foreach ($v['child'] as $kk => &$vv) {

                        unset($menu[$k]['child'][$kk]['child'][$kkk]);
                    }
                }
                if (empty($vv['child'])) {

                }
            }
            if (empty($v['child'])) {
                unset($menu[$k]);
            }
        }
        return $menu;
    }

    //获取当前用户的权限ID集合数组
    public static function get_current_admin_permission($admin_id = null) {
        $result = Admin::where('id', $admin_id)->first(['admin_group_ids']);
        $result_new = $result->toArray();

        $permission_ids = [];

                foreach ($v as $kk => $vv) {

            }
        }
        $permission_ids_array = array_unique($permission_ids);

        //防止数据出错

    }

    //递归数据
    public static function tree_menu($menu = null, $parent = 0) {
        $tree = array();
        foreach ($menu as $v) {
            if ($v['parent_permission_id'] == $parent) {

                if (empty($v['child'])) {
                    unset($v['child']);
                }

            }
        }
        return $tree;
    }
