如何在slim3中注入更复杂的服务，例如Paytrail

Question

下面是“ Paytrail_Module_Rest.php”的示例代码，“ Paytrail_Module_Rest.php”是用于与支付网关的其他api进行交互的一组类。 某些类可以提前实例化，例如（持有凭据的Paytrail_Module_rest），但是有些类需要使用仅控制器中可用的信息实例化（例如Paytrail_Module_Rest_Payment_S1来设置付款明细，例如价格）

谁能建议将它注入slim3的干净方法？ 我看不到使用标准容器注入方法执行此操作的任何好方法。

$urlset = new\App\Service\Paytrail\Paytrail_Module_Rest_Urlset(
    "https://www.demoshop.com/sv/success", // return address for successful payment
    "https://www.demoshop.com/sv/failure", // return address for failed payment
    "https://www.demoshop.com/sv/notify",  // address for payment confirmation from Paytrail server
    ""  // pending url not in use
);

$orderNumber = '1';
$price = 99.00;
$payment = new \App\Service\Paytrail\Paytrail_Module_Rest_Payment_S1($orderNumber, $urlset, $price);

$payment->setLocale('en_US');

$module = new \App\Service\Paytrail\Paytrail_Module_Rest(13466, '6pKF4jkv97zmqBJ3ZL8gUw5DfT2NMQ');

try {
    $result = $module->processPayment($payment);
}
catch (\App\Service\Paytrail\Paytrail_Exception $e) {
    die('Error in creating payment to Paytrail service:'. $e->getMessage());
}

echo $result->getUrl();

（此处列出的凭证是公共测试凭证）

将不会改变的内容添加到容器中，例如模块和urlset

$container[\App\Service\Paytrail\Paytrail_Module_Rest_Urlset::class] = function($c) {
    return new \App\Service\Paytrail\Paytrail_Module_Rest_Urlset(
        "https://www.demoshop.com/sv/success", // return address for successful payment
        "https://www.demoshop.com/sv/failure", // return address for failed payment
        "https://www.demoshop.com/sv/notify",  // address for payment confirmation from Paytrail server
        ""  // pending url not in use
    );
};

$container[\App\Service\Paytrail\Paytrail_Module_Rest::class] = function($c) {
    return new \App\Service\Paytrail\Paytrail_Module_Rest(13466, '6pKF4jkv97zmqBJ3ZL8gUw5DfT2NMQ');
};

然后，您可以在每次需要时实例化付款，或添加诸如适配器之类的帮助程序类：

class PaymentAdapter {

    public function __construct(
            \App\Service\Paytrail\Paytrail_Module_Rest $module,
            \App\Service\Paytrail\Paytrail_Module_Rest_Urlset $urlset) 
    {
        $this->module = $module;
        $this->urlset = $urlset;
    }

    function createAndProcessPayment($orderNumber, $price) 
    {
        $payment = new \App\Service\Paytrail\Paytrail_Module_Rest_Payment_S1($orderNumber, $this->urlset, $price);

        $payment->setLocale('en_US');
        try {
            $result = $module->processPayment($payment);
        }
        catch (\App\Service\Paytrail\Paytrail_Exception $e) {
            die('Error in creating payment to Paytrail service:'. $e->getMessage());
        }
        return $result;
    }

}

然后将适配器也添加到容器中：

$container[\yournamespace\PaymentAdapter::class] = function($c) {
    return new \yournamespace\PaymentAdapter(
        $c[\App\Service\Paytrail\Paytrail_Module_Rest::class],
        $c[\App\Service\Paytrail\Paytrail_Module_Rest_Urlset::class]
    );
};
