我正在尝试使用dodirectpayment NVP设置paypal api，我从在线资源中组装了一些代码，但是当我提交它时，我没有得到任何响应，只是一个白屏。我注意到我的代码中没有任何回显，但我不确定如何回显贝宝发送的任何响应。任何帮助都会很棒。所有客户信息和凭据都来自沙箱。谢谢！

  enter code here <?php 

class Paypal {
   /**
    * Last error message(s)
    * @var array
    */
   protected $_errors = array();

   /**
    * API Credentials

   protected $_credentials = array(

      $ch = curl_init();
      curl_setopt_array($ch,$curlOptions);

      //Sending our request - $response will hold the API response
      $response = curl_exec($ch);

      //Checking for cURL errors
      if (curl_errno($ch)) {
         $this -> _errors = curl_error($ch);
         curl_close($ch);
         return false;

   }
}

$requestParams = array(

$paypal = new Paypal();
$response = $paypal -> request('DoDirectPayment',

);

if( is_array($response) && $response['ACK'] == 'Failure') { // Payment successful
   // We'll fetch the transaction ID for internal bookkeeping
    $transactionId = $response['TRANSACTIONID'];


}


?>

我对 PHP 有点陌生，所以希望我的错误太愚蠢了，谢谢！

您似乎启用了 CURL 对等证书验证，您可能希望将其禁用以进行测试，直到您在服务器上设置它。

代替：

CURLOPT_SSL_VERIFYPEER => true,
CURLOPT_SSL_VERIFYHOST => 2,
CURLOPT_CAINFO => dirname(__FILE__) . '/cacert.pem', //CA cert file

和：

CURLOPT_SSL_VERIFYPEER => FALSE,
CURLOPT_SSL_VERIFYHOST => FALSE,

另外，要检查响应，只需添加

print_r($response);

以下：

$response = $paypal -> request('DoDirectPayment',
   $requestParams + $creditCardDetails + $payerDetails + $orderParams + $item
);

让我帮助您获得以下完整代码：

<?php

此外，您可能希望将您的沙盒业务帐户升级到 Pro，参考此链接： https ://stackoverflow.com/a/21926016/4410290

希望这可以帮助.. ：）

如果你得到一个空白的白色屏幕，这意味着发生了一个 PHP 错误，但你没有启用错误报告。

将此添加到脚本的最顶部。

error_reporting(E_ALL);
ini_set('display_errors', '1');

然后再次运行脚本，您应该会看到错误。
