我在我的网站上使用PayumBundle进行paypal集成。 我已经设置了捆绑包，如中所述 https://github.com/Payum/PayumBundle/blob/master/Resources/doc/get_it_started.md
并为payum安装了paypal express checkout nvp extension。
这是我的控制者：
$gatewayName = 'paypal-express-checkout-nvp';
$storage = $this->get('payum')->getStorage(PaymentDetails::class);
$details = $storage->create();
$details['PAYMENTREQUEST_0_CURRENCYCODE'] = 'CHF';
$details['PAYMENTREQUEST_0_AMT'] = $amount;
$storage->update($details);
$captureToken = $this->get('payum')->getTokenFactory()->createCaptureToken(
$gatewayName, $details, 'payment_done'
);
return $this->redirect($captureToken->getTargetUrl());
这是配置文件：
payum:
security:
token_storage:
MyBundle\Entity\PaymentToken: { doctrine: orm }
storages:
MyBundle\Entity\PaymentDetails: { doctrine: orm }
gateways:
paypal-express-checkout-nvp:
factory: paypal_express_checkout
username: %paypal_user%
password: %paypal_password%
signature: %paypal_signature%
sandbox: true
然而，当我提交表格时，我收到以下错误“
Catchable Fatal Error: Argument 3 passed to Payum\Paypal\ExpressCheckout\Nvp\Api::__construct() must be an instance of Http\Message\MessageFactory, null given, called in vendor/payum/paypal-express-checkout-nvp/Payum/Paypal/ExpressCheckout/Nvp/PaypalExpressCheckoutGatewayFactory.php on line 89 and defined in vendor/payum/paypal-express-checkout-nvp/Payum/Paypal/ExpressCheckout/Nvp/Api.php at 317
我看了一下PaypalExpressCheckoutGatewayFactory类，其中config在第89行的populateConfig函数中传递，
return new Api($paypalConfig, $config['payum.http_client'], $config['httplug.message_factory']);
键'httplug.message_factory'没有在任何地方定义？

确保您payum/core版本至少为1.3。

我在Symfony3中遇到了同样的问题。 要解决此问题，请添加数组键=＆gt;值：
httplug.message_factory' => new GuzzleMessageFactory()
在PaypalExpressCheckoutGatewayFactory配置数组中。 我会尝试找到更好的解决方案并稍后更新帖子。
您还必须添加此使用声明：
use Http\Message\MessageFactory\GuzzleMessageFactory;
修改 我终于在没有更改库的情况下使用它，但实际上我不知道如何。我在我的服务器上安装了应用程序，然后安装了php composer.phar install -o并且它可以工作。
