Paypal IPN问题与并行支付 [英] Paypal IPN Issue with parallel payment
本文介绍了Paypal IPN问题与并行支付的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在使用此 http://www.binpress.com/ app / paypal-adaptive-payments-pro-codeigniter-library / 140 库，我使用它作为我的ipn监听器为codeigniter项目 - http://pastebin.com/pMb7Zhz3 。
I'm using this http://www.binpress.com/app/paypal-adaptive-payments-pro-codeigniter-library/140 library and i'm using this as my ipn listener for a codeigniter project - http://pastebin.com/pMb7Zhz3.
基本上，我使用上面的paypal库进行并行事务，以便当用户付款/捐赠，它将钱汇到2个不同的帐户。一旦一个事务完成，paypal发送数据到我的ipn监听器，它解析1个客户的信息很好，如果我离开这个'IPNNotificationURL'=> ''在我的代码，并进入paypal并设置ipn url。
Basically i'm doing a parallel transaction using the paypal library above so that when a user makes a payment/donation, it sends money to 2 different accounts. Once a transaction is complete, paypal sends data to my ipn listener and it parses info for 1 customer just fine if I leave this 'IPNNotificationURL' => '' in my code and go into paypal and set the ipn url.
我想要获取这两个帐户的IPN信息，而不必让两个帐户都在其paypal设置中设置ipn url。当我设置'IPNNotificationURL'=> 'http://example.com/paypal_ipn'，我仍然获得了1个帐户的ipn信息，但我收到此警告第11行的数组到字符串转换我的监听器。我如何解决这个问题，如果我这样做，我会从这两个帐户获取ipn信息吗？
I'm trying to get IPN information for both accounts, without having to have both accounts set the ipn url in their paypal settings. When I set 'IPNNotificationURL' => 'http://example.com/paypal_ipn', I still get the ipn information for the 1 account, but I get this warning Array to string conversion on line 11 of my listener. How can I fix this and if i do, will I get the ipn information from both accounts?
这是从上面的库的付款方法，我用于并行付款
Here's the pay method from the library above that i'm using for the parallel payments
function Pay()
{
// Prepare request arrays
$PayRequestFields = array(
'ActionType' => 'PAY', // Required. Whether the request pays the receiver or whether the request is set up to create a payment request, but not fulfill the payment until the ExecutePayment is called. Values are: PAY, CREATE, PAY_PRIMARY
'CancelURL' => '', // Required. The URL to which the sender's browser is redirected if the sender cancels the approval for the payment after logging in to paypal.com. 1024 char max.
'CurrencyCode' => 'USD', // Required. 3 character currency code.
'FeesPayer' => 'SENDER', // The payer of the fees. Values are: SENDER, PRIMARYRECEIVER, EACHRECEIVER, SECONDARYONLY
'IPNNotificationURL' => '', // The URL to which you want all IPN messages for this payment to be sent. 1024 char max.
'Memo' => '', // A note associated with the payment (text, not HTML). 1000 char max
'Pin' => '', // The sener's personal id number, which was specified when the sender signed up for the preapproval
'PreapprovalKey' => '', // The key associated with a preapproval for this payment. The preapproval is required if this is a preapproved payment.
'ReturnURL' => '', // Required. The URL to which the sener's browser is redirected after approvaing a payment on paypal.com. 1024 char max.
'ReverseAllParallelPaymentsOnError' => '', // Whether to reverse paralel payments if an error occurs with a payment. Values are: TRUE, FALSE
'SenderEmail' => '', // Sender's email address. 127 char max.
'TrackingID' => '' // Unique ID that you specify to track the payment. 127 char max.
);
$ClientDetailsFields = array(
'CustomerID' => '', // Your ID for the sender 127 char max.
'CustomerType' => '', // Your ID of the type of customer. 127 char max.
'GeoLocation' => '', // Sender's geographic location
'Model' => '', // A sub-identification of the application. 127 char max.
'PartnerName' => '' // Your organization's name or ID
);
$FundingTypes = array('ECHECK', 'BALANCE', 'CREDITCARD');
$Receivers = array();
$Receiver = array(
'Amount' => '', // Required. Amount to be paid to the receiver.
'Email' => '', // Receiver's email address. 127 char max.
'InvoiceID' => '', // The invoice number for the payment. 127 char max.
'PaymentType' => '', // Transaction type. Values are: GOODS, SERVICE, PERSONAL, CASHADVANCE, DIGITALGOODS
'PaymentSubType' => '', // The transaction subtype for the payment.
'Phone' => array('CountryCode' => '', 'PhoneNumber' => '', 'Extension' => ''), // Receiver's phone number. Numbers only.
'Primary' => '' // Whether this receiver is the primary receiver. Values are: TRUE, FALSE
);
array_push($Receivers,$Receiver);
$SenderIdentifierFields = array(
'UseCredentials' => '' // If TRUE, use credentials to identify the sender. Default is false.
);
$AccountIdentifierFields = array(
'Email' => '', // Sender's email address. 127 char max.
'Phone' => array('CountryCode' => '', 'PhoneNumber' => '', 'Extension' => '') // Sender's phone number. Numbers only.
);
$PayPalRequestData = array(
'PayRequestFields' => $PayRequestFields,
'ClientDetailsFields' => $ClientDetailsFields,
'FundingTypes' => $FundingTypes,
'Receivers' => $Receivers,
'SenderIdentifierFields' => $SenderIdentifierFields,
'AccountIdentifierFields' => $AccountIdentifierFields
);
$PayPalResult = $this->paypal_adaptive->Pay($PayPalRequestData);
if(!$this->paypal_adaptive->APICallSuccessful($PayPalResult['Ack']))
{
$errors = array('Errors'=>$PayPalResult['Errors']);
$this->load->view('paypal_error',$errors);
}
else
{
$data['result'] = $PayPalResult;
$this->load->view('success', $data);
}
}
，第11行是上面的pastebin - $ value = urlencode（stripslashes（$ value））;
and line 11 is this from the pastebin above - $value = urlencode(stripslashes($value));
推荐答案
I想出了如何解析PHP中的自适应支付IPN。
I figured out how to parse the adaptive payments IPN in PHP.
I used the DecodePayPalIPN() function by donut2d https://www.x.com/developers/paypal/forums/adaptive-payments-api/php-technique-parsing-adaptive-payment-ipn-posts?page=0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C0%2C1 in combination with one of the example listeners that is on the paypal website and here is my complete Codeigniter IPN Listener for adaptive payments with a parallel transaction.
