如何在Yii2中配置和访问`$ app-＆gt; params ['uploadPath']`

Question

1. 我创建了

   namespace common\components;
   use yii\base\BootstrapInterface;
   
   class Bootstrap implements BootstrapInterface
   {
       public function bootstrap($app)
       {
           // Here you can refer to Application object through $app variable
           $app->params['uploadPath'] = $app->basePath . '/uploads/';
           $app->params['uploadUrl'] => $app->urlManager->baseUrl . '/uploads/';
       }
   }
   

2

    'bootstrap' => [
        ...
        'common\components\Bootstrap',
    ];

如何在我的控制器和视图中访问$app->params['uploadPath']。 提前谢谢。

如果要访问应用程序参数，则不必使用BootstrapInterface。您只需致电：

\Yii::$app->params['uploadPath'];

您可以在params项下的应用程序配置中设置params。
