Swoft 容器使用

能夠藉助Swoft下的Bean類操做容器app

示例:this

將類綁定至容器url

use Swoft\Bean\Annotation\Bean;

/**
 * @Bean("imageLogic")
 */
class ImageLogic extends BaseLogic
{
    /**
     * 根據id獲取圖片
     * @param int $id
     * @return array
     */
    public static function getOne(int $id): array
    {
        return Query::table(Image::class)->where('id',$id)->limit(1)->get(['url','thumb_url'])->getResult();
    }
}

從容器中取出對象:spa

方法一:注入code

use Swoft\Bean\Annotation\Inject;
use App\Models\Logic\ImageLogic;

class IndexController{
    /**
     * @Inject("imageLogic")
     * @var ImageLogic
     */
    private $imageLogic;
  
    public function index()
    {
        $this->imageLogic->getOne();
    }         
}

方法二:經過 BeanFactory 類獲取對象

use Swoft\Bean\BeanFactory;

class IndexController
{
    /**
     * @RequestMapping(route="index",method=RequestMethod::GET)
     */
    public function index(Request $request){
        //判斷容器中是否存在該實例
        var_dump(BeanFactory::hasBean('imageLogic'));
        //從容器中獲取
        $bean = BeanFactory::getBean('imageLogic');
        return $bean->getOne();
    }

}
