1.更改配置项
~~~
// 默认输出类型
// 'default_return_type' => 'html',
'default_return_type' => 'json',
~~~
2.让模型中的Banner.php继承think\Model
~~~
<?php
namespace app\api\model;
use think\Db;
use think\Model;
class Banner extends Model
{
public static function getBannerById($id)
{
//$result=Db::query('select * from banner_item where banner_id=?',[$id]);
$result=Db::table('banner_item')
->where(
function ($query) use ($id){
$query->where('banner_id','=',$id);
}
)->select();
return $result;
}
}
~~~
3.Banner.php文件
~~~
<?php
namespace app\api\controller\v1;
use app\api\validate\IDMustBePostiveInt;
use app\api\model\Banner as BannerModel;
use app\lib\exception\BannerMissException;
class Banner{
//获取指定id的banner信息
public function getBanner($id)
{
(new IDMustBePostiveInt())->goCheck();
$banner=BannerModel::get($id);
if(!$banner){
throw new BannerMissException();
}
return $banner;
}
}
~~~
结果
