php - Yii2 - 在运行时附加组件

Question

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

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 中添加如下值:

'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
  ],

Answer 1

如果您需要在运行时从数据库提供这些凭据，您可以使用 setComponents() 通过代码进行定义。 yii\base\Application 类的方法，您可以在其中从数据库中检索 paypal 的设置并将其从配置文件中删除。

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();
