使用数据库中的配置初始化应用程序组件 [英] Init application component with config from database

问题描述

我正在构建一个Yii2应用程序，该应用程序通过 swiftmailer扩展发送电子邮件.我将电子邮件设置(smtp，ssl，用户名等)存储在数据库表中，以便能够通过适当的视图对其进行编辑. 如何通过db表中的config初始化swiftmailer?

I'm building a Yii2 application that sends email through the swiftmailer extension. I store the email settings (smtp, ssl, username, etc..) in a database table, to be able to edit them with an apposite view. How can I init swiftmailer with config from the db table?

谢谢.

推荐答案

您可以使用

You can initialize application components using set() method available through application object Yii::$app:

use Yii;

...

// Get config from db here

Yii::$app->set('mailer', [
    'class' => 'yii\swiftmailer\Mailer',
    'transport' => [
        'class' => 'Swift_SmtpTransport',
        // Values from db
        'host' => ... 
        'username' => ...
        'password' => ...
        'port' => ...
        'encryption' => ...
    ],
]);

然后照常使用它:

use Yii;

...

Yii::$app->mailer->...

如果要对整个应用程序使用数据库中的相同配置，则可以在应用程序引导期间获取并应用此配置.

If you want to use the same configuration from database for the whole application, you can get and apply this config during application bootstrap.

创建自定义类并将其放置在例如app/components;

Create custom class and place it for example in app/components;

namespace app\components;

use yii\base\BootstrapInterface;

class Bootstrap implements BootstrapInterface
{
    public function bootstrap($app)
    {
        // Put the code above here but replace Yii::$app with $app
    }
}

然后将其添加到配置中:

Then add this in config:

return [
    [
        'app\components\Bootstrap',
    ],
];

请注意:

如果已经存在具有相同ID的组件定义，则它将为 覆盖.

If a component definition with the same ID already exists, it will be overwritten.
