专题、分类、商品详情接口编写

2、模型关联–关联与查询

12、theme接口与验证与重构

\controller\v1\Theme.php

<?php

namespace app\api\controller\v1;

use app\api\validate\IDCollection;

class Theme
{
    public function getSimpleList($ids=''){
        (new IDCollection())->goCheck();
        return 'success';
    }
}

\validate\IDCollection.php

<?php

namespace app\api\validate;


class IDCollection extends BaseValidate
{
   protected $rule = [
       'ids' => 'require|checkIDs'
   ];

   protected $message = [
       'ids' => 'ids参数必须为以逗号分割的正整数'
   ];

   protected function checkIDs($value){
       $values = explode(',',$value);//以逗号分隔数组
       if (empty($values)){
           return false;
       }
       foreach ($values as $id){//遍历数组元素，必须为正整数
            if (!$this->isPositiveInteger($id)) {
                return false;
            }
       }
       return true;
   }

}

18、最近新品接口编写

\controller\Product.php

<?php

namespace app\api\controller\v1;

use app\api\model\Product as ProductModel;
use app\api\validate\Count;
use app\lib\exception\ProductException;

class Product
{
    function getRencent($count = 15){
        (new Count()) -> goCheck();
        $products = ProductModel::getMostRencent($count);
        if (!$products){
            throw new ProductException();
        }
        return $products;
    }
}

\lib\exception\ProductException.php

<?php

namespace app\lib\exception;


class ProductException extends BaseException
{
    public $code = 404;
    public $msg = '指定的商品不存在';
    public $errorCode = 20000;
}

\model\Production.php

<?php

namespace app\api\model;


class Product extends BaseModel
{
    protected $hidden = [
        'delete_time', 'main_img_id','pivot','create_time',
        'update_time', 'from','category_id'
    ];
    //读取器
    public function getMainImgUrlAttr($value,$data){
        return $this->prefixImageUrl($value,$data);
    }

    public static function getMostRencent($count){
        $products = self::limit($count)
            ->order('create_time desc')
            ->select();
        return $products;
    }
}
