Question

下面的代码对于成功的贝宝交易（没有paypal-mock-response）没有错误。

当我在"PayPal-Mock-Response:{\"mock_application_codes\": \"MALFORMED_REQUEST\"}"中添加CURLOPT_HTTPHEADER来测试不同的senario时，如贝宝在https://developer.paypal.com/docs/api/request-headers/#test-api-error-handling-routines上建议的那样 curl_error()返回The requested URL returned error: 404 Not Found

问题一定是我在"PayPal-Mock-Response:{\"mock_application_codes\": \"MALFORMED_REQUEST\"}"中添加CURLOPT_HTTPHEADER的方式，但是我还没有弄清楚。

没有PayPal-Mock-Response的交易中的print_r（$ result），以帮助解决问题：

Answer 1

根据HTTP404和官方documentation ...

curl_setopt($curl, CURLOPT_URL, PayPal_BASE_URL.'payments/payment/' . $paymentID. '/execute');

CURLOPT_URL似乎缺少动词后面的/execute。

，并涉及到HTTP400……可能需要先create次付款（并记住paymentId），然后再execute次付款-同时传回相应的PaymentID

当我在CURLOPT_HTTPHEADER中添加PayPal-Mock-Response时出现404 curl_error
