Model层(GoodstypeModel)代码:
<?php
namespace appcommonmodel;
use thinkException;

class GoodsTypeModel extends BaseModel {
    protected $name = 'goods_type';
    protected $resultSetType = 'collection';
    public function getGoodsList($where=false,$field=false,$order=false){
        try{
            $list = self::with(['attach'])->where($where)->field($field)->order($order)->select();
            if(empty($list)){
                return self::showReturnCodeWithOutData(2003);
            }else{
                return self::showReturnCode(200,['list'=>$list->toArray()]);
            }
        }catch (Exception $e){
            return self::showReturnCodeWithOutData(2002,$e->getMessage());
        }
    }
    public function attach(){
        return $this->hasOne('AttachModel','id','category_photo');
    }
}

最后这里 api接口 (把数据库所有内容作为参数上传到小程序)
<?php
namespace appapicontroller;

use appcommonmodelGoodsTypeModel;
use appcommonmodelVersionsModel;
use thinkConfig;
class Classify extends Common {
    private $goodsClassify;
    public function index()
    {
        $goodsClassify = new GoodsTypeModel();
        $list_result = $goodsClassify ->getList(false,false,false);
            if($list_result['code']==200){
            $list = [];
            foreach ($list_result['data']['list'] as $k=>$v){
                $v['name'] = str_replace(' ','',$v['name']);
                $list[] = $v;
            }
            return self::showJsonReturnCode(200,['list'=>$list]);
            }elseif($list_result['code']==2003){
                return self::showJsonReturnCode(200);
            }else{
                return self::showJsonReturnCodeWithOutData(400,$list_result['msg']);
            }
    }
}
