我正在努力理解新的PayPal自适应支付API - 特别是ConvertCurrency功能。是否有人在PHP中成功实现了这一点?

使用Paypal的自适应支付SDK非常容易将货币转换为不同的货币。假设您拥有必要的信息(API用户名/密码等)来向API发出请求,可以按如下方式完成:
<?php
//First we need to include the class file of the Adaptive Payments
include 'AdaptivePayments.php';
// Create an instance, you'll make all the necessary requests through this
// object, if you digged through the code, you'll notice an AdaptivePaymentsProxy class
// wich has in it all of the classes corresponding to every object mentioned on the
// documentation of the API
$ap = new AdaptivePayments();
// Our request envelope
$requestEnvelope = new RequestEnvelope();
$requestEnvelope->detailLevel = 0;
$requestEnvelope->errorLanguage = 'en_US';
// Our base amount, in other words the currency we want to convert to
// other currency type. It's very straighforward, just have a public
// prop. to hold de amount and the current code.
$baseAmountList = new CurrencyList();
$baseAmountList->currency = array( 'amount' => 15, 'code' => 'USD' );
// Our target currency type. Given that I'm from Mexico I would like to
// see it in mexican pesos. Again, just need to provide the code of the
// currency. On the docs you'll have access to the complete list of codes
$convertToCurrencyList = new CurrencyCodeList();
$convertToCurrencyList->currencyCode = 'MXN';
// Now create a instance of the ConvertCurrencyRequest object, which is
// the one necessary to handle this request.
// This object takes as parameters the ones we previously created, which
// are our base currency, our target currency, and the req. envelop
$ccReq = new ConvertCurrencyRequest();
$ccReq->baseAmountList = $baseAmountList;
$ccReq->convertToCurrencyList = $convertToCurrencyList;
$ccReq->requestEnvelope = $requestEnvelope;
// And finally we call the ConvertCurrency method on our AdaptivePayment object,
// and assign whatever result we get to our variable
$result = $ap->ConvertCurrency($ccReq);
// Given that our result should be a ConvertCurrencyResponse object, we can
// look into its properties for further display/processing purposes
$resultingCurrencyList = $result->estimatedAmountTable->currencyConversionList;
$baseAmount = $resultingCurrencyList->baseAmount->amount;
$baseAmountCode = $resultingCurrencyList->baseAmount->code;
$convertedAmount = $resultingCurrencyList->currencyList->currency->amount;
$convertedAmountCode = $resultingCurrencyList->currencyList->currency->code;
echo '<br /> $' . $baseAmount . ' ' . $baseAmountCode . ' is $' . $convertedAmount . ' ' . $convertedAmountCode;
// And here just for the sake of knowing how we get the result from Paypal's API
echo '<pre>';
print_r($result);
echo '</pre>';
输出应该类似于:
$15 USD is $159.75 MXN
ConvertCurrencyResponse Object
(
[responseEnvelope] => ResponseEnvelope Object
(
[timestamp] => 2010-04-20T13:27:40.278-07:00
[ack] => Success
[correlationId] => b940006680f6a
[build] => 1238639
)
[estimatedAmountTable] => stdClass Object
(
[currencyConversionList] => CurrencyConversionList Object
(
[baseAmount] => stdClass Object
(
[code] => USD
[amount] => 15
)
[currencyList] => CurrencyList Object
(
[currency] => currency Object
(
[code] => MXN
[amount] => 159.75
)
)
)
)
)
正如您所看到的,使用ConvertCurrency API非常简单,只需下载SDK并开始使用即可;)
