Laravel框架角色、权限

角色表结构如下：

权限表结构如下：

控制器代码：

  //递归查询权限列表
    public function index(){
        $data = ManagePermissionModel::query()->get()->toArray();
        $array = $this->recursion($data, $pid = 0);
        return $this->success($array);
    }

    /***
     * 获取取全树
     */
    public function navList(){
        $operationModel = new ManagePermissionModel();
        $query = $operationModel->where('type','<>','a')->orderBy('sort', 'asc')->get()->toArray();
        $tree = PHPTree::makeTreeForHtml($query,array(
            'parent_key' => 'pid',
            'primary_name' => 'name',
            'primary_code' => 'code',
        ));
        return $this->success($tree);
    }

    public function menus(){
        $operationModel = new ManagePermissionModel();
        $menus = $operationModel->where('perm_type','<',3)->orderBy('sort', 'asc')->get()->toArray();
        $r = PHPTree::makeTreeForHtml($menus,array(
            'parent_key' => 'pid',
            'primary_name' => 'name',
            'primary_code' => 'code',
        ));
        return $this->success($r);
    }

    /**
     * 创建栏目
     * @param OperationRequest $request
     */
    public function create(OperationRequest $request){
        $operation = [
            'permission_name' => $request->permission_name,
            'address' => $request->address,
            'type' => $request->type,
            'pid' => $request->pid,
            'parent_menu_id' => $request->parent_menu_id,
            'perm_type' => $request->perm_type,
            'sort' => $request->sort,
        ];
        $addPermission = ManagePermissionModel::query()->create($operation);
        if ($addPermission){
            return $this->success($addPermission, "创建成功");
        } else {
            return $this->failed("创建失败");
        }
    }

    public function del(CheckIdRequest $request){
        $id = $request->id;
        $del = ManagePermissionModel::query()->where(['id' => $id])->delete();
        if ($del){
            return $this->success($del, "删除成功");
        }else{
            return  $this->failed("删除失败");
        }
    }

    public function edit(OperationRequest $request){
        if (empty($request['id']) || !is_numeric($request['id'])){
            return  $this->failed("非法传参");
        }
        $operation = [
            'permission_name' => $request->permission_name,
            'address' => $request->address,
            'type' => $request->type,
            'pid' => $request->pid,
            'parent_menu_id' => $request->parent_menu_id,
            'id' => $request->id,
            'perm_type' => $request->perm_type,
            'sort' => $request->sort,
        ];
        $edit = ManagePermissionModel::query()->where(['id' => $operation['id']])->update($operation);
        if ($edit){
            return $this->success($edit, "修改成功");
        } else {
            return $this->failed("修改失败");
        }
    }

模型层代码：

/**
     * 根据传过来的数组，构建以parent_menu_id为父节点的菜单树..
     * @param $list 构建树所需要的节点，此值是根据权限节点算出来的
     * @param $parent_menu_id   构建树的根节点
     * @return array
     */
    public function createTree($list,$parent_menu_id){
        $data = [];
        foreach($list as $k => $v){
            if($v['parent_menu_id'] == $parent_menu_id){
                $row = $v;
                //取当前节点的url
                // $row['url'] = $this->getUrl($v['id']);
                $row['children'] = $this->createTree($list,$v['id']);
                $data[] = $row;
            }
        }
        return $data;
    }

    /**
     * 根据当前节点，取出当前节点的url，用于后台菜单节点的url生成
     * @param $operation_id
     * @param $list
     */
    private function getUrl($operation_id){
        static $list = [];
        if(!$list){
            $all = ManagePermissionModel::query()->get();
            if(!$all->isEmpty()){
                $all = $all->toArray();
            }else{
                $all = [];
            }
            foreach($all as $v){
                $list[$v['id']] = $v;
            }
        }

        if(!isset($list[$operation_id])){
            return "";
        }
        if($list[$operation_id]['type'] == 'm'){
            return url($list[$operation_id]['code'] . '/index/index');          //一个模型，搞什么url？
        }
        if($list[$operation_id]['type'] == 'c'){
            if(isset($list[$list[$operation_id]['pid']])){
                return url($list[$list[$operation_id]['pid']]['code'] . '/'.$list[$operation_id]['code'].'/index');
            }else{
                return "";
            }
        }
        if($list[$operation_id]['type'] == 'a'){
            //取控制器
            if(isset($list[$list[$operation_id]['pid']]) && isset($list[$list[$list[$operation_id]['pid']]['pid']])){
                return url($list[$list[$list[$operation_id]['pid']]['pid']]['code'] . '/'.$list[$list[$operation_id]['pid']]['code'].'/'.$list[$operation_id]['code']);
            }else{
                return "";
            }
        }
        return "";
    }

在Laravel框架配置里封装：

配置目录：

封装代码：

/**
     * 根据父级id查找子级数据
     * @param $data 要查询的数据
     * @param int $pid 父级id
     */
    public function recursion($data, $pid = 0)
    {
        // 定义存储子级数据数组
        $child = [];
        foreach ($data as $key => $value) {
            if ($value['pid'] == $pid) {
                // 使用过后可以销毁
                unset($data[$key]);
                // 递归调用，查找当前数据的子级
                $value['child'] = $this->recursion($data, $value['id']);
                // 把子级数据添加进数组
                $child[] = $value;
            }
        }
        return $child;
    }
