Yii2 - 在运行时附加组件

我确实从数据库中动态询问了组件中设置值的问题，为 swiftmailer 提供了示例。同样得到了完美的回答here https://stackoverflow.com/questions/56708214/yii2-setting-value-in-config-from-component-or-database#56708214

但该答案仅适用于邮件程序组件，因此我如何实现类似的功能，例如，我需要在 config.php 中添加以下值：

'pp' => [ 
    'class' => 'app/components/paypal', // note: this has to correspond with the newly created folder, else you'd get a ReflectionError

     // Next up, we set the public parameters of the class
    'client_id' => 'YOUR-CLIENT-ID-FROM-PAYPAL',
    'client_secret' => 'YOUR-CLIENT-SECRET-FROM-PAYPAL',
    // You may choose to include other configuration options from PayPal
    // as they have specified in the documentation
  ],

如果您需要在运行时从数据库提供这些凭据，您可以使用代码通过代码定义它setComponents() https://www.yiiframework.com/doc/api/2.0/yii-di-servicelocator#setComponents()-detail的方法yii\base\Application您将从 PayPal 数据库中检索设置并将其从配置文件中删除的类。

添加以下行以在运行时设置组件，然后调用所需的方法

Yii::$app->setComponents(
    [
        'pp' => [
            'class' => 'app/components/paypal', //note: this has to correspond with the newly created folder, else you'd get a ReflectionError

            // Next up, we set the public parameters of the class
            'client_id' => 'YOUR-CLIENT-ID-FROM-PAYPAL',
            'client_secret' => 'YOUR-CLIENT-SECRET-FROM-PAYPAL'
            // You may choose to include other configuration options from PayPal
            // as they have specified in the documentation
        ]
    ]
);

//now you can call the desired method for the pp with the above credentials
Yii::$app->pp->checkout();
