php - Paypal PHP Curl不返回任何内容

在使用实时凭据成功在本地主机上测试我的付款请求之后，我将应用程序联机。

但是，在实时服务器上，curl请求没有任何回报，甚至没有错误消息。这是完全相同的请求，可以完美地在localhost上运行。

$url = 'curl -s --insecure -H "X-PAYPAL-SECURITY-USERID: '.$userId.'" -H "X-PAYPAL-SECURITY-PASSWORD: '.$password.'" -H "X-PAYPAL-SECURITY-SIGNATURE: '.$signature.'" -H "X-PAYPAL-REQUEST-DATA-FORMAT: JSON" -H "X-PAYPAL-RESPONSE-DATA-FORMAT: JSON" -H "X-PAYPAL-APPLICATION-ID: '.$applicationId.'" https://svcs.paypal.com/AdaptivePayments/Pay -d "{\"actionType\":\"PAY\", \"currencyCode\":\"'.$currency.'\", \"receiverList\":{\"receiver\":[{\"amount\":\"'.$amount.'\",\"email\":\"'.$receiverEmail.'\"}]}, \"returnUrl\":\"'.$successUrl.'\", \"cancelUrl\":\"'.$failUrl.'\", \"requestEnvelope\":{\"errorLanguage\":\"en_US\", \"detailLevel\":\"ReturnAll\"}}';
$result = json_decode(exec($url));

现在就是PHP。我试图在命令行中运行curl请求。在本地主机上，我立即获得正确的回报。在实时服务器上，我首先得到一个“>”符号，然后再次粘贴命令并输入，它会给我一些输出。

{"responseEnvelope":{"timestamp":"2013-07-05T13:16:26.305-07:00","ack":"Failure","correlationId":"2b8ab6998078e","build":"6520082"},"error":[{"errorId":"580001","domain":"PLATFORM","subdomain":"Application","severity":"Error","category":"Application","message":"Invalid request: {0}"}]}

奇怪的是，它可以在localhost上运行，但不能在实时服务器上运行，因此我认为这在PHP，curl或服务器设置上一定有所不同...但是我真的没有任何线索。

最佳答案

echo $ url的输出是什么？

为什么通过exec运行curl？为什么不使用mod_curl？

例如...

 $API_Endpoint = "";
    if ($sandbox) {
      $API_Endpoint = "https://svcs.sandbox.paypal.com/AdaptivePayments";
    }
    else{
      $API_Endpoint = "https://svcs.paypal.com/AdaptivePayments";
  }

  $API_Endpoint .= "/" . $methodName;

  //setting the curl parameters.
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $API_Endpoint);
  curl_setopt($ch, CURLOPT_VERBOSE, 1);
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
  curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_POST, 1);

  // Set the HTTP Headers
  curl_setopt($ch, CURLOPT_HTTPHEADER,  array(
  'X-PAYPAL-REQUEST-DATA-FORMAT: NV',
  'X-PAYPAL-RESPONSE-DATA-FORMAT: NV',
  'X-PAYPAL-SECURITY-USERID: '. $API_UserName,
  'X-PAYPAL-SECURITY-PASSWORD: '. $API_Password,
  'X-PAYPAL-SECURITY-SIGNATURE: '. $API_Signature,
  'X-PAYPAL-APPLICATION-ID: '. $API_AppID
  ));

  // RequestEnvelope fields
  $detail_level = urlencode("ReturnAll"); // See DetailLevelCode in the WSDL for valid enumerations
  $error_language = urlencode("en_US"); // This should be the standard RFC 3066 language identification tag, e.g., en_US

  // NVPRequest for submitting to server
  $nvp_req = "requestEnvelope.errorLanguage=$error_language&requestEnvelope.detailLevel=$detail_level";
  $nvp_req .= "&$nvp_str";

  //setting the nvp_req as POST FIELD to curl
  curl_setopt($ch, CURLOPT_POSTFIELDS, $nvp_req);

  //getting response from server
  $response = curl_exec($ch);
