用法

• 创建一个 Wucdbm\Component\Epay\Client\ClientOptions 实例，该实例负责提供 Wucdbm\Component\Epay\Client\Client 所需的所有选项。其构造函数需要 epay.bg 提供的商户 ID 和密钥。记得根据是否测试，将构造函数的第三个参数设置为 true 或 false。
• 创建一个实现了 Wucdbm\Component\Epay\Client\PaymentHandlerInterface 接口的处理器。该接口包含客户端调用的方法
• 创建一个 Wucdbm\Component\Epay\Client\Client 的实例，并传递上述两个
• 要创建支付表单，调用 $client->getEpayForm($id, $amount, $description, $expiry, $formId, $okUrl, $cancelUrl)
• 要创建 EasyPay 支付 ID，调用 $response = $this->client->getEasyPayIdn($id, $amount, $description, $expiry)。这将返回一个 Wucdbm\Component\Epay\Response\EasyPayResponse 响应。调用 $response->getIdn() 获取 ID。请注意，此方法会抛出 Wucdbm\Component\Epay\Exception\EasyPayGetIdnError 异常。

WucdbmEpayBundle https://packagist.org.cn/packages/wucdbm/epay-bundle 使用了此库，前往该链接查看更多示例。

$options = new \Wucdbm\Component\Epay\Client\ClientOptions($merchantId, $merchantSecret, $isDebug);
// $options->set... to alter any options
$handler = new \My\Project\Payments\Epay\PaymentHandler(LogManager $some, PaymentManager $dependencies);
$client = new \Wucdbm\Component\Epay\Client\Client($options, $handler);

获取支付表单的步骤如下

$uniqId = uniqid(); // this is to make autosubmitting easy - $('#formId').submit();
$expiry = new \DateTime('today + 2 days');
// ... other parameters
$form = $client->getEpayForm($id, $amount, $description, $expiry, $formId, $okUrl, $cancelUrl);
// Display the form and optionally auto submit it. Another option is to alter the submit button through the options and let the user do that

获取 EasyPay IDN

$id = $payment->getId();
$amount = $payment->getAmount();
$description = 'Payment #' . $payment->getId();
$expiry = $payment->getExpiryDate();

try {
    $response = $this->client->getEasyPayIdn($id, $amount, $description, $expiry);
    $idn = $response->getIdn();
    // display idn to the user, do some logging.
    // the response body is available at $response->getBody();
    return $idn;
} catch (\Wucdbm\Component\Epay\Exception\EasyPayGetIdnError $ex) {
    $this->logEasyPayRequest($payment, $ex->getBody(), true);
    throw $ex;
}

接收支付

$response = $client->receiveResponse($post);
// the client will call your handler, which must deal with the payments received
// $response is an \Wucdbm\Component\Epay\Response\ReceiveResponseInterface instance
// exceptions are caught internally and transformed into responses, the no data exception and checksum mismatch exceptions in particular generate a global error response for epay
echo $response->toString();
exit();
// alternatively, if you use Symfony's HttpFoundation component
$response = \Symfony\Component\HttpFoundation\Response($response->toString());
