Question

这部分对我来说很新，所以这可能是一个非常明显的答案。我在我的Android应用程序中使用了PayPal MPL，在PHP的服务器端使用了这个来验证付款：

function verify_paypal($payKey, $appID)
{
  global $payPalUser_Id, $payPalPassword, $payPalSig, $amount, $currency;
$headerArray = array(
'X-PAYPAL-SECURITY-USERID:'.$payPalUser_Id,
'X-PAYPAL-SECURITY-PASSWORD:'.$payPalPassword,
'X-PAYPAL-SECURITY-SIGNATURE:'.$payPalSig,
'X-PAYPAL-APPLICATION-ID:'.$appID,
'X-PAYPAL-REQUEST-DATA-FORMAT:NV',
'X-PAYPAL-RESPONSE-DATA-FORMAT:XML'
);

$url="https://svcs.paypal.com/AdaptivePayments/PaymentDetails?payKey={$payKey}&requestEnvelope.errorLanguage=en_US";

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headerArray);

$adaptiveResponse = curl_exec($ch);
curl_close($ch);

if (!is_null($adaptiveResponse)){

  //check result
  $dom_document = new DOMDocument();
  $dom_document->loadXML($adaptiveResponse);
  $searchNode = $dom_document->getElementsByTagName("responseEnvelope"); 

foreach( $searchNode as $searchNode ) 
{ 
    $xmlResponse = $searchNode->getElementsByTagName( "ack" ); 
    $valueResponse = $xmlResponse->item(0)->nodeValue; 
} 

if (strtolower($valueResponse) =="failure"){
      return false;
    }

$xml=simplexml_load_string($adaptiveResponse);
$valueCurrency=$xml->currencyCode;
$valueStatus=$xml->status;

$searchNode = $dom_document->getElementsByTagName("receiver"); 

foreach( $searchNode as $searchNode ) 
{ 
    $xmlAmount = $searchNode->getElementsByTagName( "amount" ); 
    $valueAmount = $xmlAmount->item(0)->nodeValue; 

    $xmlEmail = $searchNode->getElementsByTagName( "email" ); 
    $valueEmail = $xmlEmail->item(0)->nodeValue; 
} 

$searchNode = $dom_document->getElementsByTagName("paymentInfo"); 

foreach( $searchNode as $searchNode ) 
{ 
    $xmlSenderStatus = $searchNode->getElementsByTagName( "senderTransactionStatus" ); 
    $valueSenderStatus = $xmlSenderStatus->item(0)->nodeValue;  
} 

if ((strtolower($valueStatus) =="completed")&&(strtolower($valueSenderStatus) =="completed")&&(strtolower($valueEmail) =="mymail@paypal.com")&&($valueAmount==$amount)&&($valueCurrency==$currency)){
  return true;
} else {
  return false;
}
}
return false;
};

但是使用新的Android SDK我得到了一个PaymentConfirmation对象：

PaymentConfirmation confirm = data.getParcelableExtra(PaymentActivity.EXTRA_RESULT_CONFIRMATION);

我如何从确认中获得$ payKey，还是应该以不同的方式验证付款？

根据您使用的MSDK版本，您可能需要使用自己使用的自适应付款或REST API。请查看此页面，了解如何验证付款https://developer.paypal.com/docs/integration/mobile/verify-mobile-payment/

PayPal服务器端确认
