paypal批量支付api在php中的使用

Question

我正在尝试通过此代码使用 Paypal Mass Payment API，但出现此错误。

我将此代码保存到文件“MassPay.php”并上传到我的本地主机。我正在尝试测试代码，如果我可以让它工作，我将在核心 php 中使用它，每月向教师支付大量费用。

使用此代码“MassPay.php”

<?php

// Include required library files.
require_once('includes/config.php');
require_once('includes/paypal.class.php');

// Create PayPal object.
$PayPalConfig = array('Sandbox' => $sandbox, 'APIUsername' => $api_username, 'APIPassword' => $api_password, 'APISignature' => $api_signature);
$PayPal = new PayPal($PayPalConfig);

// Prepare request arrays
$MPFields = array(
    'emailsubject' => 'dudhat@artoongames.com', // The subject line of the email that PayPal sends when the transaction is completed.  Same for all recipients.  255 char max.
    'currencycode' => 'USD', // Three-letter currency code.
    'receivertype' => 'EmailAddress'       // Indicates how you identify the recipients of payments in this call to MassPay.  Must be EmailAddress or UserID
);

// Typically, you'll loop through some sort of records to build your MPItems array. 
// Here I simply include 3 items individually.  

$Item1 = array(
    'l_email' => 'dudhat@gmail.com', // Required.  Email address of recipient.  You must specify either L_EMAIL or L_RECEIVERID but you must not mix the two.
    'l_receiverid' => 'dudhat@gmail.com', // Required.  ReceiverID of recipient.  Must specify this or email address, but not both.
    'l_amt' => '10.00', // Required.  Payment amount.
    'l_uniqueid' => '522', // Transaction-specific ID number for tracking in an accounting system.
    'l_note' => 'test payment'         // Custom note for each recipient.
);

$Item2 = array(
    'l_email' => 'dilip@gmail.com', // Required.  Email address of recipient.  You must specify either L_EMAIL or L_RECEIVERID but you must not mix the two.
    'l_receiverid' => 'dilip@gmail.com', // Required.  ReceiverID of recipient.  Must specify this or email address, but not both.
    'l_amt' => '1.00', // Required.  Payment amount.
    'l_uniqueid' => '523', // Transaction-specific ID number for tracking in an accounting system.
    'l_note' => 'test payment'         // Custom note for each recipient.
);



$MPItems = array($Item1,$Item2);  // etc

$PayPalRequestData = array('MPFields' => $MPFields, 'MPItems' => $MPFields);

// Pass data into class for processing with PayPal and load the response array into $PayPalResult
$PayPalResult = $PayPal->MassPay($PayPalRequestData);

// Write the contents of the response array to the screen for demo purposes.
echo '<pre />';
print_r($PayPalResult);
?>

Answer 1

您在 $MPItems 中组装了一些付款项目，但没有将 $MPItems 添加到 PayPal 请求数据中。因此 PayPal 拒绝了批量付款，因为其中不包含任何付款项目。

Answer 2

您可以使用以下类进行批量支付交易

使用模式（live/sandbox）的实际您的贝宝凭据定义您的常量。

class PaypalnvpComponent {

    private static $API_Username = PAYPAL_API_USERNAME;
    private static $API_Password = PAYPAL_API_PASSWORD;
    private static $API_Signature = PAYPAL_API_SIGNATURE;
    private static $API_Environment = PAYPAL_API_MODE;
    private static $API_Version = '116.0';

    public static function Call($methodName,$params){
        if(self::$API_Environment == 'LIVE'){
            $API_Endpoint = "https://api-3t.paypal.com/nvp";            
        }else{
            $API_Endpoint = "https://api-3t.sandbox.paypal.com/nvp";
        }

        $nvpstr = "";
        foreach($params as $k=>$v){
            $nvpstr .="&".$k."=".urlencode($v);
        }

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $API_Endpoint);
        curl_setopt($ch, CURLOPT_VERBOSE, 1);

        //Turn of server and pakagemanager
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);

        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

        //set the API operation,version,API signature in requrest

        $nvpreq ="";

            return "$methodName failed:".curl_error($ch).'('.curl_errno($ch).')';
        }

        //Extract the response details

        $httpResponseArray = explode('&', $httpResponse);

        $httpParsedResponseArray = array();

        foreach ($httpResponseArray as $i=>$value){
            $tmpArray = explode('=', $value);
            if(sizeof($tmpArray) > 1){
                $httpParsedResponseArray[$tmpArray[0]] = urldecode($tmpArray[1]);
            }
        }
        if((0 == sizeof($httpParsedResponseArray)) || !array_key_exists('ACK',$httpParsedResponseArray)){
            return "Invalid HTTP Response for POST request($nvpreq) to $API_Endpoint.";

        }
        return $httpParsedResponseArray;        
    }
