对外接口获取分类修复

原因说明：对外接口获取分类报错

修改文件：app\dao\product\category\StoreProductCategoryDao

修改方法：getALlByIndex()

public function getALlByIndex(array $where, string $field = 'id,cate_name,pid,pic,relation_id', $limit = 0)
    {
        $pid = $where['pid'] ?? -1;
        if (isset($where['relation_id']) && (int)$where['relation_id'] == 0 || !isset($where['relation_id'])) {
            $where['type'] = 0;
        } elseif (isset($where['relation_id']) && (int)$where['relation_id'] > 0) {
            $where['type'] = 1;
        }else{
            $where['type'] = 0;
        }
        return $this->getModel()->where('is_show', 1)->field($field)
            ->when(in_array($pid, [0, -1]), function ($query) use ($pid) {
                switch ($pid) {
                    case -1://所有一级
                        $query->where('pid', 0);
                        break;
                    case 0://所有二级
                        $query->where('pid', '>', 0);
                        break;
                }
            })->when((int)$pid > 0, function ($query) use ($pid) {
                $query->where('pid', $pid);
            })->when(isset($where['relation_id']) && (int)$where['relation_id'] > 0, function ($query) use ($where) {

            })->when(isset($where['type']), function ($query) use ($where) {

                $query->limit($limit);
            })->order('sort DESC')->select()->toArray();
    }
