以下代码适用于成功的paypal交易没有错误（没有paypal-mock-response）。
当我在qazxsw poi中添加qazxsw poi来测试不同的场景，因为paypal建议在"PayPal-Mock-Response:{\"mock_application_codes\": \"MALFORMED_REQUEST\"}" CURLOPT_HTTPHEADER返回https://developer.paypal.com/docs/api/request-headers/#test-api-error-handling-routines
问题必须是我在curl_error()添加The requested URL returned error: 404 Not Found的方式，但我还没弄明白。
paypal_button.php
"PayPal-Mock-Response:{\"mock_application_codes\": \"MALFORMED_REQUEST\"}"process.php
CURLOPT_HTTPHEADER没有PayPal-Mock-Response的事务中的print_r（$ result），如果它有帮助：

HTTP404documentation似乎缺少尾随的curl_setopt($curl, CURLOPT_URL, PayPal_BASE_URL.'payments/payment/' . $paymentID. '/execute');
，作为动词。
并关于那CURLOPT_URL ...可能需要首先/execute支付（并记住paymentId）然后HTTP400支付 - 同时传回相应的paymentID。
