PayPal IPN回发失败 [英] PayPal IPN postback failure

问题描述

我最近将我的Magento实时网站从1.6.2.0升级到1.7.0.0. 从升级后开始，我现在在贝宝标准付款中遇到问题. 当客户使用PayPal付款时，PayPal上的付款会顺利进行，但是Magento订单状态不会更新，而是保持待处理"状态.

I have recently upgraded my Magento live website from 1.6.2.0 to 1.7.0.0. Starting after the upgrade, I now have a issue in PayPal Standard Payment. When a customer pays by using PayPal, the payment on PayPal goes smoothly, but the Magento order state is not updated and stays in "pending" state.

我已经检查了多个报告此问题的网站，但仍然无法解决问题.

I have checked various websites reporting this, but I can't still solve the problem.

我有payment_paypal_standard.log报告此: .... [postback_result] => [例外] => PayPal IPN回发失败.有关详细信息，请参见paypal_unknown_ipn.log."

I have the payment_paypal_standard.log reporting this: ".... [postback_result] => [exception] => PayPal IPN postback failure. See paypal_unknown_ipn.log for details."

但是我没有创建paypal_unknown_ipn.log，因此无法获得有关该错误的更多信息.

But I have no paypal_unknown_ipn.log being created, so I can't have more info about the error.

进行更多调查，我发现可能的麻烦是返回的PayPal回发字符串未正确解密，但是我没有找到真正的解决方案来帮助我解决问题.

Investigating more, I have found the possible trouble is that the returning PayPal postback string is not correctly decrypted, but I have not found a real solution that help me to solve the problem.

有没有一种方法可以很快找到解决方案? 谢谢大家.

Is there a way to find a solution shortly? Thank you all in advance.

推荐答案

请参见 http://doghouse.agency/article/debugging-paypal-ipn-postback-failures-magento

基本上，CURL有时会决定在回发请求标头中添加期望:100"字段，以检查是否允许发送此请求.这会导致CURL响应字符串与Magento(最高1.7)的预期值不同

Basically, CURL sometimes decides to add a "Expect: 100" field to the postback request-header to check if it's allowed to send this request. This causes the CURL response string to be different than what Magento (up to 1.7) expects

更改

$response = preg_split('/^\r?$/m', $response, 2);
$response = trim($response[1]);

到

$response = preg_split('/^\r?$/m', $response);
$response = trim(end($response));

，它应该可以解决此特定问题.当然，您可能会遇到其他问题，例如CURL错误.在这种情况下，请记录CURL错误号.有关CURL错误编号的列表，请参见此页面: http://curl.haxx. se/libcurl/c/libcurl-errors.html

and it should fix this specific issue. Of course, you could be experiencing a different issue, ie a CURL error. In that case, log the CURL error number. See this page for a list of CURL error numbers: http://curl.haxx.se/libcurl/c/libcurl-errors.html
