我下载了 paypalplatform.php,不记得从哪里下载的,但它给了我一个不错的小功能,可以让我检查付款状态:

CallPaymentDetails( $payKey, $transactionId, $trackingId );

这会返回许多有用的数据,例如status等等paymentInfoList.paymentInfo(0).transactionStatus

我知道我可以写很多if语句来尝试解释调用时返回给我的所有值CallPaymentDetails,我觉得这很容易出错,或者可能导致我忽略一个场景。

所以我的问题是,是否存在一个将所有值都考虑在内的示例模板,也就是说,我不必重新发明轮子来处理所有场景?

例如,目前我有:

$resArray = CallPaymentDetails( $payKey, $transactionId, $trackingId );

if(strtoupper($resArray["responseEnvelope.ack"]) == "SUCCESS") {

    if(strtoupper($resArray["status"]) == "CREATED") {

        // do something

    } elseif(strtoupper($resArray["status"]) == "EXPIRED") {

        // do something

    } elseif(strtoupper($resArray["status"]) == "COMPLETED") {

        // do something

        if(strtoupper($resArray["paymentInfoList.paymentInfo(0).transactionStatus"]) == "PENDING") {

            // do something

        } elseif(strtoupper($resArray["paymentInfoList.paymentInfo(0).transactionStatus"]) == "FAILED") {

            // do something

        } else {

            // what other value could be returned

        }

    } else {

        // what other value could be returned

    }

} else {

    // what other value could be returned

}

如果我尝试做所有的变量,我可能会永远试图捕捉所有的场景,这就是为什么我想知道这样的模板是否已经存在,它通过 if 语句满足所有场景?

首先,您不应该在互联网上抓取文件,例如paypalplatform.php.

Paypal大量使用 Github 来共享所有不同语言的所有 API。我真的建议您查看一些存储库,例如:

最后两个对你来说很有趣。它们都为您的案例提供了有用的代码示例。

代码示例-php

它提供了对您提到的函数的简单调用,并描述了可以使用一个变量找到的所有返回消息$response->status。评论揭示了这个变量可以有的所有情况:

if ($response->responseEnvelope->ack == "Success")
{

  // The status of the payment. Possible values are:
  //
  // * CREATED - The payment request was received; funds will be
  // transferred once the payment is approved
  // * COMPLETED - The payment was successful
  // * INCOMPLETE - Some transfers succeeded and some failed for a
  // parallel payment or, for a delayed chained payment, secondary
  // receivers have not been paid
  // * ERROR - The payment failed and all attempted transfers failed
  // or all completed transfers were successfully reversed
  // * REVERSALERROR - One or more transfers failed when attempting
  // to reverse a payment
  // * PROCESSING - The payment is in progress
  // * PENDING - The payment is awaiting processing
  $logger->log("Payment Status : ".$response->status);
}

自适应支付-sdk-php

它提供了有关如何使用函数的更详细示例。它从 html 表单中获取值,更容易对其进行测试。与前面的示例一样,我们可以看到 API 返回的相同状态:

$ack = strtoupper($response->responseEnvelope->ack);
if($ack != "SUCCESS"){
  echo "<b>Error </b>";
  echo "<pre>";
  print_r($response);
  echo "</pre>";
} else {
/*
 *       The status of the payment. Possible values are:

       * CREATED - The payment request was received; funds will be
       transferred once the payment is approved
       * COMPLETED - The payment was successful
       * INCOMPLETE - Some transfers succeeded and some failed for a
       parallel payment or, for a delayed chained payment, secondary
       receivers have not been paid
       * ERROR - The payment failed and all attempted transfers failed
       or all completed transfers were successfully reversed
       * REVERSALERROR - One or more transfers failed when attempting
       to reverse a payment
       * PROCESSING - The payment is in progress
       * PENDING - The payment is awaiting processing
 */
  echo "<table>";
  echo "<tr><td>Ack :</td><td><div id='Ack'>$ack</div> </td></tr>";
  echo "<tr><td>PayKey :</td><td><div id='PayKey'>$response->payKey</div> </td></tr>";
  echo "<tr><td>Status :</td><td><div id='Status'>$response->status</div> </td></tr>";
  echo "</table>";
  echo "<pre>";
  print_r($response);
  echo "</pre>";
}

在这两种情况下,您只需要一个简单的开关/案例来处理响应状态。像这样的东西:

switch ($status)
{
  case 'CREATED':
    // handle CREATED state
    break;
  case 'COMPLETED':
    // handle COMPLETED state
    break;
  case 'INCOMPLETE':
    // handle INCOMPLETE state
    break;
  case 'ERROR':
    // handle ERROR state
    break;
  case 'REVERSALERROR':
    // handle REVERSALERROR state
    break;
  case 'PROCESSING':
    // handle PROCESSING state
    break;
  case 'PENDING':
    // handle PENDING state
    break;

  default:
    throw new Exception(sprintf("State '%s' isn't handle.", $status));
}
