ECSHOP 小程序接口 
整个接口基于THINKPHP5开发 
部分文件目录

分类接口源码：

<?php  
namespace app\common\model;  
use think\Model;  
class Category extends Model  
{  
    protected static $allChildrenIds = [];  
    public function getChildrenIds($cat_id,$include = 1){  
        if(empty($cat_id)){  
            return [];  
        }

            $cat_id = [$cat_id];  
        }  
        $cat_id = array_unique($cat_id);  
        sort($cat_id);  
        $cat_id_str = implode('_', $cat_id);  
        if(isset(self::$allChildrenIds[$cat_id_str])){
