php - 为什么 PayPal 的快速结帐失败且没有错误？

Question

PayPal 在从 JavaScript 调用的 checkout.php 中的第一步失败。我正在使用沙箱并尝试在本地和服务器上运行它。我发了一个技术。支持请求解释了问题，但 3 天后我没有收到他们的任何回复。我猜这应该归咎于天气。

下面包含一串似乎都正确输入的参数。它还包含空白错误消息:

nvpstr=&PAYMENTREQUEST_0_AMT=15.00&PAYMENTREQUEST_0_PAYMENTACTION=销售&RETURNURL= http://jquery.bunkerhill.com/php/orderconfirm.php&CANCELURL=http://jquery.bunkerhill.com/php/cancel.php&PAYMENTREQUEST_0_CURRENCYCODE=USD&REQCONFIRMSHIPPING=0&NOSHIPPING=1&L_PAYMENTREQUEST_0_NAME0=jQuery-Translator&L_PAYMENTREQUEST_0_AMT0=15.00&L_PAYMENTREQUEST_0_QTY0=1&L_PAYMENTREQUEST_0_ITEMCATEGORY0=Digital

ACK=SetExpressCheckout API 调用失败。

您一定从 PayPal 收到了空白响应，这意味着您可能遇到了 curl 错误，这意味着您可能遇到了 SSLv3 握手失败，PayPal 刚刚在 2016 年 1 月 19 日打开了开关.

这是 PayPal 因为 POODLE vulnerability 而做的事情.

您应该做的是检查 curl 错误，以验证这是您遇到的问题(我几乎可以保证，因为自从他们打开开关后我们看到了很多错误。)

然后，最简单的方法就是联系您的网络托管服务商并说明您遇到了这个问题，他们需要更新您的服务器以修复它。它基本上归结为服务器软件堆栈，特别是 OpenSSL，更新到正确处理 TLS 回退的受支持版本。
