Palpal大规模支付响应

Question

我正在使用Paypal Masspayment API，它的工作很好，但是我想知道我为交易支付了多少费用，或者交易是国内的还是国际的，但是我只是得到这个数组的回应。

Array
(
     [TIMESTAMP] => 2015%2d02%2d03T05%3a31%3a25Z
     [CORRELATIONID] => 1bccbfad582e7
     [ACK] => Success
     [VERSION] => 51%2e0
     [BUILD] => 15110743
)

甚至可以使用大众支付API吗？

或者，如果有任何方法来获得计算结果，我的网站从这个大支付费用计算器？批次-付款-概览-外部

我更喜欢用PHP编写的解决方案

Answer 1

Paypal不共享任何机密信息，因此它可能是不可能的，但您可以使用curl计算费用，以下是工作代码

    $url = "https://www.paypal.com/np/cgi-bin/webscr";
    $data=array(
      "cmd" => '_calc-masspay-fee',
      "sender_country" => $Country,
      "receiver_country" => 'GB',
      "currency_code" => Mage::app()->getStore()->getCurrentCurrencyCode(),
      "curr_list_reqd" => 1
    );

    $cr = curl_init($url);
    curl_setopt($cr, CURLOPT_RETURNTRANSFER, true);       // Get returned value as string (dont put to screen)
    curl_setopt($cr, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']); // Spoof the user-agent to be the browser that the user is on (and accessing the php $
    curl_setopt($cr, CURLOPT_POST, true);                 // Tell curl that we are posting data
    curl_setopt($cr, CURLOPT_POSTFIELDS, $data);          // Post the data in the array above
    $output = curl_exec($cr); 

    $output = json_decode($output);

处理此问题的最佳方法是设置一个即时付款通知书(IPN)解决方案。当您进行MassPay事务时，您将得到包含更多详细信息的IPN。下面是一个例子：

Array
(
    [payer_id] => ATSCG2QMC9KAU
    [payment_date] => 09:23:59 Jan 28, 2015 PST
    [payment_gross_1] => 10.00
    [payment_gross_2] => 10.00
    [payment_gross_3] => 10.00
    [payment_status] => Processed
    [receiver_email_1] => andrew_1342623385_per@angelleye.com
    [receiver_email_2] => usb_1329725429_biz@angelleye.com
    [charset] => windows-1252
    [receiver_email_3] => andrew_1277258815_per@angelleye.com
    [mc_currency_1] => USD
    [masspay_txn_id_1] => 1M205262R4107805K
    [mc_currency_2] => USD
    [masspay_txn_id_2] => 95942086WL824160N
    [mc_currency_3] => USD
    [masspay_txn_id_3] => 21W68993Y67646416
    [first_name] => Drew
    [unique_id_1] => 
    [notify_version] => 3.8
    [unique_id_2] => 
    [unique_id_3] => 
    [payer_status] => verified
    [verify_sign] => AJ-yMngskqU0wKMAcE2BE6cQ.uxhA3cw3neNnb2W68Ic2ZwqkxjYIgMg
    [payer_email] => sandbo_1215254764_biz@angelleye.com
    [payer_business_name] => Drew Angell's Test Store
    [last_name] => Angell
    [status_1] => Completed
    [status_2] => Completed
    [status_3] => Completed
    [txn_type] => masspay
    [mc_gross_1] => 10.00
    [mc_gross_2] => 10.00
    [mc_gross_3] => 10.00
    [payment_fee_1] => 0.20
    [residence_country] => US
    [test_ipn] => 1
    [payment_fee_2] => 0.20
    [payment_fee_3] => 0.20
    [mc_fee_1] => 0.20
    [mc_fee_2] => 0.20
    [mc_fee_3] => 0.20
    [ipn_track_id] => 205e7228cfda3
)

该特定的MassPay包含3项付款，因此您可以看到每一项单独的数据，可以循环通过并相应地进行处理。

在GitHub和/或Packagist上有很多用于IPN的PHP类，如果您正在使用它，也可以与Composer一起使用。如果您正在使用WordPress，我会查看用于PayPal WordPress的IPN，它会让您非常快速地启动和运行，然后您可以轻松地扩展它来处理您自己的需求。
