如何从PayPal SDK访问交易数据？

Question

I am working with the PayPal SDK, and when I finish a transaction it returns this:

object(PayPal\Api\Payment)#8 (1) {

  }
}

I am not sure what it is. (I think it is JSON but I am not sure.)

What I want to do is get access to that info in this kind of array:

$transaction["payment"]

How can I do that?

Answer 1

PayPal returns an object that is formatted using its own internal fromJSON() function - in the OP's case it was called from the Payment class:

$json = $call->execute(array('PayPal\Rest\RestHandler'), "/v1/payments/payment/{$this->getId()}/execute", "POST", $payLoad);
$ret = new Payment();
$ret->fromJson($json);
return $ret;

To use this as a JSON object, you need to use the toJSON() function:

$execution = new PaymentExecution();
$execution->setPayerId($_GET['PayerID']);
//Execute the payment
// (See bootstrap.php for more on `ApiContext`)
$result = $payment->execute($execution, $apiContext);
// use the result 
$jsonResult = $result->toJSON();

I hope this helps.
