paypal - 如何在 Paypal 定期配置文件快速结帐中的 CallShortcutExpressCheckout 后调用 CreateRecurringPaymentsProfile

Question

我已经在我的网站上下载并实现了这个 paypal 集成库。 https://github.com/hrendoh/PayPal-Express-Checkout-example

没有创建重复配置文件。

快速结帐的函数调用是

  $resArray = CallShortcutExpressCheckout ($paymentAmount, $currencyCodeType, $paymentType, $returnURL, $cancelURL);
  $ack = strtoupper($resArray["ACK"]);
  if($ack=="SUCCESS" || $ack=="SUCCESSWITHWARNING")
  {
  // if SetExpressCheckout is returned with success, move to paypal site for payments.
  RedirectToPayPal ( $resArray["TOKEN"] );
  } 


function CallShortcutExpressCheckout( $paymentAmount, $currencyCodeType, $paymentType, $returnURL, $cancelURL) 
    {
        //------------------------------------------------------------------------------------------------------------------------------------
        // Construct the parameter string that describes the SetExpressCheckout API call in the shortcut implementation

        $nvpstr="&AMT=". $paymentAmount;
        $nvpstr = $nvpstr . "&PAYMENTACTION=" . $paymentType;
        $nvpstr = $nvpstr . "&BILLINGAGREEMENTDESCRIPTION=".urlencode("Test Recurring Payment($1 monthly)");
        $nvpstr = $nvpstr . "&BILLINGTYPE=RecurringPayments";
        $nvpstr = $nvpstr . "&RETURNURL=" . $returnURL;
        $nvpstr = $nvpstr . "&CANCELURL=" . $cancelURL;
        $nvpstr = $nvpstr . "&CURRENCYCODE=" . $currencyCodeType;

        $_SESSION["currencyCodeType"] = $currencyCodeType;    
        $_SESSION["PaymentType"] = $paymentType;

        //'--------------------------------------------------------------------------------------------------------------- 
        //' Make the API call to PayPal
        //' If the API call succeded, then redirect the buyer to PayPal to begin to authorize payment.  
        //' If an error occured, show the resulting errors
        //'---------------------------------------------------------------------------------------------------------------

        $resArray=hash_call("SetExpressCheckout", $nvpstr);
        $ack = strtoupper($resArray["ACK"]);
        if($ack=="SUCCESS" || $ack=="SUCCESSWITHWARNING")
        {
            $token = urldecode($resArray["TOKEN"]);
            $_SESSION['TOKEN']=$token;
        }

        return $resArray;
    }

此函数用于创建一个循环配置文件，该配置文件不会在示例代码中的任何地方调用。

function CreateRecurringPaymentsProfile()
    {
        //'--------------------------------------------------------------
        //' At this point, the buyer has completed authorizing the payment
        //' at PayPal.  The function will call PayPal to obtain the details
        //' of the authorization, incuding any shipping information of the
        //' buyer.  Remember, the authorization is not a completed transaction
        //' at this state - the buyer still needs an additional step to finalize
        //' the transaction
        //'--------------------------------------------------------------
        $token      = urlencode($_SESSION['TOKEN']);
        $email      = urlencode($_SESSION['email']);
        $shipToName     = urlencode($_SESSION['shipToName']);
        $shipToStreet       = urlencode($_SESSION['shipToStreet']);
        $shipToCity     = urlencode($_SESSION['shipToCity']);
        $shipToState        = urlencode($_SESSION['shipToState']);
        $shipToZip      = urlencode($_SESSION['shipToZip']);
        $shipToCountry  = urlencode($_SESSION['shipToCountry']);

        //'---------------------------------------------------------------------------
        //' Build a second API request to PayPal, using the token as the
        //'  ID to get the details on the payment authorization
        //'---------------------------------------------------------------------------
        $nvpstr="&TOKEN=".$token;
        #$nvpstr.="&EMAIL=".$email;
        $nvpstr.="&SHIPTONAME=".$shipToName;
        $nvpstr.="&SHIPTOSTREET=".$shipToStreet;
        $nvpstr.="&SHIPTOCITY=".$shipToCity;
        $nvpstr.="&SHIPTOSTATE=".$shipToState;
        $nvpstr.="&SHIPTOZIP=".$shipToZip;
        $nvpstr.="&SHIPTOCOUNTRY=".$shipToCountry;
        $nvpstr.="&PROFILESTARTDATE=".urlencode("2011-07-01T0:0:0");
        $nvpstr.="&DESC=".urlencode("Test Recurring Payment($1 monthly)");
        $nvpstr.="&BILLINGPERIOD=Month";
        $nvpstr.="&BILLINGFREQUENCY=5";
        $nvpstr.="&AMT=1";
        $nvpstr.="&CURRENCYCODE=USD";
        $nvpstr.="&IPADDRESS=" . $_SERVER['REMOTE_ADDR'];

        //'---------------------------------------------------------------------------
        //' Make the API call and store the results in an array.  
        //' If the call was a success, show the authorization details, and provide
        //'     an action to complete the payment.  
        //' If failed, show the error
        //'---------------------------------------------------------------------------
        $resArray=hash_call("CreateRecurringPaymentsProfile",$nvpstr);
        $ack = strtoupper($resArray["ACK"]);
        return $resArray;
    }

我可以调用此函数以在 returnurl 中创建重复配置文件并将 token ID 和付款人 ID 传递给此函数吗？

无论您使用的是什么库，流程都应该是 SetExpressCheckout , GetExpressCheckoutDetails (可选)，然后您可以跟进其中一个/或/两个 DoExpresscheckoutPayment和 CreateRecurringPaymentsProfile .

如果您打算使用 CRPP，则需要确保 SEC 包含计费协议(protocol)参数，否则在调用 CRPP 时您将遇到无效 token 错误。 Here's an old sample的 RAW API 请求流使其工作。

然后，如果你有兴趣，不妨看看我的PHP class library for PayPal让这对你来说更容易。我知道我的作品。 :)
