580001無效的請求：{0}貝寶（PHP）

Question

我從這個頁面發送用戶ID和密碼：https://www.paypal.com/us/cgi-bin/webscr?cmd=_profile-api-signature

而且將APPID我在Android應用程序使用它來創建付款ID：https://apps.paypal.com/user/my-account/applications

我使用瞭如下功能：

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

$url="https://svcs.paypal.com/AdaptivePayments/PaymentDetails?payKey={$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); 
return $adaptiveResponse; 
} 

但它給這個錯誤：

<?xml version='1.0' encoding='UTF-8'?> 
<ns3:FaultMessage xmlns:ns3="http://svcs.paypal.com/types/common" xmlns:ns2="http://svcs.paypal.com/types/ap">

</ns3:FaultMessage> 

Answer 1

請求數據格式應爲NV：

$headerArray = array(
'X-PAYPAL-SECURITY-USERID:'.$payPalUser_Id, 
'X-PAYPAL-SECURITY-PASSWORD:'.$payPalPassword, 
'X-PAYPAL-SECURITY-SIGNATURE:'.$payPalSig, 
'X-PAYPAL-REQUEST-DATA-FORMAT:NV', 
'X-PAYPAL-RESPONSE-DATA-FORMAT:JSON', 
'X-PAYPAL-APPLICATION-ID:'.$appID 
);
