1.定义路由
~~~
Route::get('api/:version/product/recent','api/:version.Product/getRecent');
~~~
2.新添Count.php验证器
~~~
<?php
namespace app\api\validate;
class Count extends BaseValidate
{
protected $rule = [
'count' => 'isPositiveInteger|between:1,15',
];
}
~~~
3.新建ProductException.php异常类
~~~
<?php
namespace app\lib\exception;
class ProductException extends BaseException
{
public $code = 404;
public $msg = '指定商品不存在，请检查商品ID';
public $errorCode = 20000;
}
~~~
4.更改Product.php模型
~~~
<?php
namespace app\api\model;
class Product extends BaseModel
{
protected $autoWriteTimestamp = 'datetime';
protected $hidden = [
'delete_time', 'main_img_id', 'pivot', 'from', 'category_id',
'create_time', 'update_time'];
public function getMainImgUrlAttr($value, $data)
{
return $this->prefixImgUrl($value, $data);
}
public static function getMostRecent($count)
{
$products = self::limit($count)
->order('create_time desc')
->select();
return $products;
}
}
~~~
5.更改Product .php控制器
~~~
<?php
namespace app\api\controller\v1;
use app\api\model\Product as ProductModel;
use app\api\validate\Count;
use app\lib\exception\ProductException;
use think\Controller;
class Product extends Controller
{
//获取指定数量的最近商品
public function getRecent($count = 15)
{
(new Count())->goCheck();
$products = ProductModel::getMostRecent($count);
if (!$products){
throw new ProductException();
}
//隐藏summary的方法
$collection=collection($products);
$products=$collection->hidden(['summary']);
return $products;
}
}
~~~
结果
