如何在slim3中注入更复杂的服务，如Paytrail

问题描述：

下面是“Paytrail_Module_Rest.php”的示例代码，这是一组用于与支付网关的其余api交互的类。某些类可以提前实例化，例如（Paytrail_Module_rest持有凭证），但有些需要用仅在控制器中可用的信息实例化（例如Paytrail_Module_Rest_Payment_S1，其设置付款细节如价格）如何在slim3中注入更复杂的服务，如Paytrail

Can任何人都建议将其注入slim3的干净方式？我看不到使用标准容器注入方法的好方法。

$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();

Slim支持任何PSR-7 HTTP消息实现。您可以为此编写一个中间件并使用操作中的属性。 – DanielO

添加不改变的容器，如模块和网址设定啄

$container[\App\Service\Paytrail\Paytrail_Module_Rest_Urlset::class] = function($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'); 
};

的东西，然后你要么可以每当需要时添加一个辅助类或者像适配器一样添加辅助类：

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] 
    ); 
};
