如何使用快速結賬創建週期性付款配置文件

Question

我目前正在將我的網站中的貝寶週期性付款過程進行整合。我用這個代碼

function process() 
    { 
    include_once("config.php"); 
    include_once("paypal.class.php"); 

    if($_POST) //Post Data received from product list page. 
{ 
    //Mainly we need 4 variables from an item, Item Name, Item Price, Item Number and Item Quantity. 
    $ItemName = $_POST["itemname"]; //Item Name 
    $ItemPrice = $_POST["itemprice"]; //Item Price 
    $ItemNumber = $_POST["itemnumber"]; //Item Number 
    $ItemQty = $_POST["itemQty"]; // Item Quantity 
    $ItemTotalPrice = ($ItemPrice*$ItemQty); //(Item Price x Quantity = Total) Get total amount of product; 


    //Data to be sent to paypal 
    $padata = '&CURRENCYCODE='.urlencode($PayPalCurrencyCode). 
       '&PAYMENTACTION=Sale'. 
       '&ALLOWNOTE=1'. 
       '&PAYMENTREQUEST_0_CURRENCYCODE='.urlencode($PayPalCurrencyCode). 
       '&PAYMENTREQUEST_0_AMT='.urlencode($ItemTotalPrice). 
       '&PAYMENTREQUEST_0_ITEMAMT='.urlencode($ItemTotalPrice). 
       '&L_PAYMENTREQUEST_0_QTY0='. urlencode($ItemQty). 
       '&L_PAYMENTREQUEST_0_AMT0='.urlencode($ItemPrice). 
       '&L_PAYMENTREQUEST_0_NAME0='.urlencode($ItemName). 
       '&L_PAYMENTREQUEST_0_NUMBER0='.urlencode($ItemNumber). 
       '&AMT='.urlencode($ItemTotalPrice). 
       '&L_BILLINGTYPE0='.urlencode('RecurringPayments'). 
       '&L_BILLINGAGREEMENTDESCRIPTION0='.urlencode('message plan').    
       '&RETURNURL='.urlencode($PayPalReturnURL). 
       '&CANCELURL='.urlencode($PayPalCancelURL); 



     //We need to execute the "SetExpressCheckOut" method to obtain paypal token 
     $paypal= new MyPayPal(); 
     $httpParsedResponseAr = $paypal->PPHttpPost('SetExpressCheckout', $padata, $PayPalApiUsername, $PayPalApiPassword, $PayPalApiSignature, $PayPalMode); 

     //Respond according to message we receive from Paypal 
     if("SUCCESS" == strtoupper($httpParsedResponseAr["ACK"]) || "SUCCESSWITHWARNING" == strtoupper($httpParsedResponseAr["ACK"])) 
     { 

       // If successful set some session variable we need later when user is redirected back to page from paypal. 
       $_SESSION['itemprice'] = $ItemPrice; 
       $_SESSION['totalamount'] = $ItemTotalPrice; 
       $_SESSION['itemName'] = $ItemName; 
       $_SESSION['itemNo'] = $ItemNumber; 
       $_SESSION['itemQTY'] = $ItemQty; 

       if($PayPalMode=='sandbox') 
       { 
        $paypalmode  = '.sandbox'; 
       } 
       else 
       { 
        $paypalmode  = ''; 
       } 
       //Redirect user to PayPal store with Token received. 
       $paypalurl ='https://www'.$paypalmode.'.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token='.$httpParsedResponseAr["TOKEN"].''; 
       header('Location: '.$paypalurl); 

     }else{ 
      //Show error message 
      echo '<div style="color:red"><b>Error : </b>'.urldecode($httpParsedResponseAr["L_LONGMESSAGE0"]).'</div>'; 
      echo '<pre>'; 
      print_r($httpParsedResponseAr); 
      echo '</pre>'; 
     } 

} 

//Paypal redirects back to this page using ReturnURL, We should receive TOKEN and Payer ID 
if(isset($_GET["token"]) && isset($_GET["PayerID"])) 
{ 
    //we will be using these two variables to execute the "DoExpressCheckoutPayment" 
    //Note: we haven't received any payment yet. 

    $token = $_GET["token"]; 
    $playerid = $_GET["PayerID"]; 

    //get session variables 
    $ItemPrice  = $_SESSION['itemprice']; 
    $ItemTotalPrice = $_SESSION['totalamount']; 
    $ItemName  = $_SESSION['itemName']; 
    $ItemNumber  = $_SESSION['itemNo']; 
    $ItemQTY  =$_SESSION['itemQTY']; 

    $padata = '&TOKEN='.urlencode($token). 
         '&PAYERID='.urlencode($playerid). 
         '&PAYMENTACTION='.urlencode("SALE"). 
         '&AMT='.urlencode($ItemTotalPrice). 
         '&CURRENCYCODE='.urlencode($PayPalCurrencyCode). 
         '&NOTIFYURL='.urlencode('http://mywebiste.com/listner'); 

    //We need to execute the "DoExpressCheckoutPayment" at this point to Receive payment from user. 
    $paypal= new MyPayPal(); 
    $httpParsedResponseAr = $paypal->PPHttpPost('DoExpressCheckoutPayment', $padata, $PayPalApiUsername, $PayPalApiPassword,    $PayPalApiSignature, $PayPalMode); 

    //Check if everything went ok.. 
    if("SUCCESS" == strtoupper($httpParsedResponseAr["ACK"]) || "SUCCESSWITHWARNING" == strtoupper($httpParsedResponseAr["ACK"])) 
    { 
      echo '<h2>Success</h2>'; 
      echo 'Your Transaction ID :'.urldecode($httpParsedResponseAr["TRANSACTIONID"]); 

       /* 
       //Sometimes Payment are kept pending even when transaction is complete. 
       //May be because of Currency change, or user choose to review each payment etc. 
       //hence we need to notify user about it and ask him manually approve the transiction 
       */ 

       if('Completed' == $httpParsedResponseAr["PAYMENTSTATUS"]) 
       { 
        echo '<div style="color:green">Payment Received! Your product will be sent to you very soon!</div>'; 
       } 
       elseif('Pending' == $httpParsedResponseAr["PAYMENTSTATUS"]) 
       { 
        echo '<div style="color:red">Transaction Complete, but payment is still pending! You need to manually authorize this payment in your <a target="_new" href="http://www.paypal.com">Paypal Account</a></div>'; 
       } 


      echo '<br /><b>Stuff to store in database :</b><br /><pre>'; 

       $transactionID = urlencode($httpParsedResponseAr["TRANSACTIONID"]); 
       $nvpStr = "&TRANSACTIONID=".$transactionID; 
       $paypal= new MyPayPal(); 
       $httpParsedResponseAr = $paypal->PPHttpPost('GetTransactionDetails', $nvpStr, $PayPalApiUsername, $PayPalApiPassword, $PayPalApiSignature, $PayPalMode); 

    if("SUCCESS" == strtoupper($httpParsedResponseAr["ACK"]) || "SUCCESSWITHWARNING" == strtoupper($httpParsedResponseAr["ACK"])) { 

       $nvpstr="&TOKEN=".$_GET['token']; 
       $nvpstr.="&BILLINGPERIOD=Month"; 
       $nvpstr.="&BILLINGFREQUENCY=1"; 
       $nvpstr.="&AMT=1"; 
       $nvpstr.="&CURRENCYCODE=USD"; 
       $nvpstr.="&COUNTRYCODE=US"; 
       $nvpstr.="&PAYERID=".$httpParsedResponseAr['PAYERID']; 
       $nvpstr.="&PROFILESTARTDATE=".date('Y-m-d'); 
       $recurr = $paypal->PPHttpPost('CreateRecurringPaymentsProfile',$nvpStr,$PayPalApiUsername, $PayPalApiPassword, $PayPalApiSignature, $PayPalMode); 

        echo '<pre>'; 
        print_r($httpParsedResponseAr); 
        echo '</pre>'; 

        print_r($recurr); 

       } else { 
        echo '<div style="color:red"><b>GetTransactionDetails failed:</b>'.urldecode($httpParsedResponseAr["L_LONGMESSAGE0"]).'</div>'; 
        echo '<pre>'; 
        print_r($httpParsedResponseAr); 
        echo '</pre>'; 

       } 

    }else{ 
      echo '<div style="color:red"><b>Error : </b>'.urldecode($httpParsedResponseAr["L_LONGMESSAGE0"]).'</div>'; 
      echo '<pre>'; 
      print_r($httpParsedResponseAr); 
      echo '</pre>'; 
    } 
} 

    } 

我得到令牌和付款人ID等。其所有工作正常。但是當我嘗試創建重複的配置文件IAM得到這個響應

Array 
(
    [TIMESTAMP] => 2013%2d03%2d18T05%3a32%3a06Z 
    [CORRELATIONID] => 912b6004f40bb 
    [ACK] => Failure

    [L_SEVERITYCODE2] => Error 
    [L_SEVERITYCODE3] => Error 
    [L_SEVERITYCODE4] => Error 
) 

我不知道我做錯了在此。

謝謝。

Answer 1

您的請求缺少一些創建定期付款資料所需的參數。請參閱https://www.x.com/developers/paypal/documentation-tools/express-checkout/integration-guide/ECRecurringPayments。

Answer 2

我認爲這個過程是錯誤的：第二次調用應該是GetExpressCheckoutDetails來檢索PAYERID以便能夠執行CreateRecurringPaymentsProfile。

只需按照本教程一步一步： https://www.x.com/developers/paypal/documentation-tools/express-checkout/how-to/ht_ec-recurringPaymentProfile-curl-etc
