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。我正在使用沙箱并在本地和服务器上尝试过运行。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。

下面有一串参数，貌似都输入正确了。它还包含空白错误消息：

nvpstr=&PAYMENTREQUEST_0_AMT=15.00&PAYMENTREQUEST_0_PAYMENTACTION=促销&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，这意味着您可能运行进入了 SSLv3 握手失败，而 PayPal 刚刚用它打开了开关2016 年 1 月 19 日。

这是 PayPal 所做的，因为 POODLE vulnerability。

您应该做的是检查 curl 错误以验证这是您运行遇到的问题（我几乎可以保证是因为他们打开开关后我们看到了很多这样的问题.)

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运行遇到了这个问题，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。
