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

对于成功的 paypal 交易(没有 paypal-mock-response )，以下代码没有错误。

当我在 CURLOPT_HTTPHEADER 中添加 "PayPal-Mock-Response:{\"mock_application_codes\":\"MALFORMED_REQUEST\"}" 以测试 paypal 建议的不同场景时在https://developer.paypal.com/docs/api/request-headers/#test-api-error-handling-routines curl_error() 返回 请求的 URL 返回错误:404 Not Found

问题必须是我在 CURLOPT_HTTPHEADER 中添加 "PayPal-Mock-Response:{\"mock_application_codes\":\"MALFORMED_REQUEST\"}" 的方式，但是我还没弄明白。

没有 PayPal-Mock-Response 的交易中的 print_r($result) 以防有帮助:

最佳答案

根据HTTP404和官方documentation ...

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

CURLOPT_URL 似乎缺少结尾的 /execute，作为动词。

关于 HTTP400 ...可能需要先 create付款(并记住 paymentId)然后到 execute该付款 - 同时传回相应的 paymentID。
