爲什麼PayPal的Express Checkout失敗並沒有錯誤？

Question

PayPal在checkout.php的第一步中失敗，這是從JavaScript調用的。我正在使用沙箱，並嘗試在本地和服務器上運行它。我發了一個技術。支持請求解釋問題，但3天后我沒有聽到任何回覆。我猜想，天氣應該歸咎於天氣。

以下內容包含所有似乎都能正確輸入的參數字符串。它還包含空白的錯誤消息：

nvpstr = & PAYMENTREQUEST_0_AMT = 15.00 & PAYMENTREQUEST_0_PAYMENTACTION =銷售& 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調用失敗。

有沒有人遇到過類似的問題呢？

必須從貝寶，這意味着你可能會得到一個錯誤捲曲，這意味着你可能跑入的SSLv3握手得到一個空白的響應返回PayPal在2016年1月19日剛翻轉交換機時出現故障。

這是貝寶做的，因爲POODLE vulnerability。

你應該做的是檢查是否有捲曲的錯誤，以驗證這是你正在運行到（我幾乎可以保證，因爲我們看到很多的它，因爲他們翻轉開關。）

問題

然後，最簡單的事情就是聯繫你的虛擬主機並解釋你遇到了這個問題，他們需要更新你的服務器來修復它。它基本上歸結爲軟件的服務器堆棧，特別是OpenSSL，更新到支持正確處理TLS回退的版本。
