PayPal IPN與PHP返回HTTP 400與IPN測試器和沙盒

我試圖將貝寶IPN整合到我的應用程序。我正處於測試的第一階段。我已經複製/粘貼此代碼： https://github.com/paypal/ipn-code-samples/blob/master/paypal_ipn.php PayPal IPN與PHP返回HTTP 400與IPN測試器和沙盒

然後，使用IPN測試儀在這裏： https://developer.paypal.com/developer/ipnSimulator

我發送一個IPN。這會返回消息「我們很抱歉，但存在HTTP錯誤，請重試。」如果我檢查檢查員，在網絡下有400錯誤。

輸出到日誌文件如下：

我已經檢查了我的服務器上的錯誤，有沒有。我也嘗試修改代碼，以解釋以下評論：

// CONFIG: Please download 'cacert.pem' from "http://curl.haxx.se/docs/caextract.html" and set the directory path 
// of the certificate as shown below. Ensure the file is readable by the webserver. 
// This is mandatory for some environments. 
//$cert = __DIR__ . "./cacert.pem"; 
//curl_setopt($ch, CURLOPT_CAINFO, $cert);

我不知道我還能檢查什麼。

如果您按照本文中介紹的有關[如何測試PayPal IPN]（https://www.angelleye.com/test-paypal-ipn/）的程序，您應該能夠追蹤到您的問題。 –

我跟隨了鏈接建議中的表單構建，這導致了額外的證據表明PHP代碼工作正常。通過多次跟蹤過程並跟蹤IPN模擬器網絡請求後，我決定嘗試通過http而不是https連接到我的站點。通過https連接是導致400錯誤的觸發器。通過http進行連接可以工作，並且不會產生錯誤。
