php - 需要使用Paypal Mass Pay API通过IPN捕获和存储接收者的详细信息

这是有关Paypal Mass Pay IPN的问题。我的平台是PHP和mySQL。

在Paypal支持网站上，我发现只有付款才有IPN。我需要在类似线路上使用IPN进行批量付款，但找不到它。还尝试尝试使用已经存在的Mass Pay NVP代码，但是那也不起作用。

我想做的是，对于已通过Mass Pay成功发送了付款的所有收件人，我想在自己的数据库表中记录他们的电子邮件，金额和unique_id。如果可能的话，我也想捕获付款状态，无论是否成功，并且基于此，我需要做一些内部处理。

现有的代码批量支付代码如下：

<?php

$environment = 'sandbox';   // or 'beta-sandbox' or 'live'

/**
 * Send HTTP POST Request
 *
 * @param   string  The API method name
 * @param   string  The POST Message fields in &name=value pair format
 * @return  array   Parsed HTTP Response body
 */
function PPHttpPost($methodName_, $nvpStr_) {
    global $environment;

    // Set up your API credentials, PayPal end point, and API version.
    $API_UserName = urlencode('my_api_username');
    $API_Password = urlencode('my_api_password');
    $API_Signature = urlencode('my_api_signature');

    $API_Endpoint = "https://api-3t.paypal.com/nvp";
    if("sandbox" === $environment || "beta-sandbox" === $environment) {
        $API_Endpoint = "https://api-3t.$environment.paypal.com/nvp";
    }
    $version = urlencode('51.0');

    // Set the curl parameters.
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $API_Endpoint);
    curl_setopt($ch, CURLOPT_VERBOSE, 1);

    // Turn off the server and peer verification (TrustManager Concept).
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);

    // Set the API operation, version, and API signature in the request.
    $nvpreq = "METHOD=$methodName_&VERSION=$version&PWD=$API_Password&USER=$API_UserName&SIGNATURE=$API_Signature$nvpStr_";

    // Set the request as a POST FIELD for curl.
    curl_setopt($ch, CURLOPT_POSTFIELDS, $nvpreq);

    // Get response from the server.
    $httpResponse = curl_exec($ch);

    if(!$httpResponse) {
        exit("$methodName_ failed: ".curl_error($ch).'('.curl_errno($ch).')');
    }

    // Extract the response details.
    $httpResponseAr = explode("&", $httpResponse);

    $httpParsedResponseAr = array();
    foreach ($httpResponseAr as $i => $value) {
        $tmpAr = explode("=", $value);
        if(sizeof($tmpAr) > 1) {
            $httpParsedResponseAr[$tmpAr[0]] = $tmpAr[1];
        }
    }

    if((0 == sizeof($httpParsedResponseAr)) || !array_key_exists('ACK', $httpParsedResponseAr)) {
        exit("Invalid HTTP Response for POST request($nvpreq) to $API_Endpoint.");
    }

    return $httpParsedResponseAr;
}

// Set request-specific fields.
$emailSubject =urlencode('example_email_subject');
$receiverType = urlencode('EmailAddress');
$currency = urlencode('USD');                           // or other currency ('GBP', 'EUR', 'JPY', 'CAD', 'AUD')

// Add request-specific fields to the request string.
$nvpStr="&EMAILSUBJECT=$emailSubject&RECEIVERTYPE=$receiverType&CURRENCYCODE=$currency";

$receiversArray = array();

for($i = 0; $i < 3; $i++) {
    $receiverData = array(  'receiverEmail' => "[email protected]",
                            'amount' => "example_amount",
                            'uniqueID' => "example_unique_id",
                            'note' => "example_note");
    $receiversArray[$i] = $receiverData;
}

foreach($receiversArray as $i => $receiverData) {
    $receiverEmail = urlencode($receiverData['receiverEmail']);
    $amount = urlencode($receiverData['amount']);
    $uniqueID = urlencode($receiverData['uniqueID']);
    $note = urlencode($receiverData['note']);
    $nvpStr .= "&L_EMAIL$i=$receiverEmail&L_Amt$i=$amount&L_UNIQUEID$i=$uniqueID&L_NOTE$i=$note";
}

// Execute the API operation; see the PPHttpPost function above.
$httpParsedResponseAr = PPHttpPost('MassPay', $nvpStr);

if("SUCCESS" == strtoupper($httpParsedResponseAr["ACK"]) || "SUCCESSWITHWARNING" == strtoupper($httpParsedResponseAr["ACK"])) {
    exit('MassPay Completed Successfully: '.print_r($httpParsedResponseAr, true));


} else  {
    exit('MassPay failed: ' . print_r($httpParsedResponseAr, true));
}

?>

在上面的代码中，如何以及在哪里添加代码以捕获上面我请求的字段？任何表示解决方案的代码都将受到高度赞赏。

非常感谢你。

最佳答案

我对定期付款更为熟悉，但是我认为IPN响应会发回您要查找的值。只需从发送回的数组中捕获它们，然后将它们放入一些变量中，然后保存到数据库即可。

$email   = $httpParsedResponseAr["receiver_email"];
$amount  = $httpParsedResponseAr["mc_currency_x"];

这是成批支付变量的值
