Paypal PDT curl 请求错误

Question

下面是我使用 paypal PDT 的 paypal 接收文件的代码

<?php

  $tx = $_GET['tx'];
  $ID = $_GET['cm'];
  $amount = $_GET['amt'];
  $currency = $_GET['cc'];
  $auth = "#####";

  // Init cURL
  $ch = curl_init(); 

  // Set request options
  $url = 'https://www.sandbox.paypal.com/cgi-bin/webscr';
  $fields = array(
      'cmd' => '_notify-synch',
      'tx' => $tx,
      'at' => $auth
  );
  curl_setopt($ch, CURLOPT_CAINFO, 'cacert.pem');
  curl_setopt($ch,CURLOPT_URL, $url);
  curl_setopt($ch,CURLOPT_POST, count($fields));
  curl_setopt($ch,CURLOPT_POSTFIELDS, http_build_query($fields));
  curl_setopt($ch,CURLOPT_RETURNTRANSFER, TRUE);
  curl_setopt($ch,CURLOPT_HEADER, FALSE);

  // Execute request and get response and status code
  $response = curl_exec($ch);
  $status   = curl_getinfo($ch, CURLINFO_HTTP_CODE);

  // Close connection
  curl_close($ch);
  print_r($response);
  if($status == 200 AND strpos($response, 'SUCCESS') === 0)
  {
      //wp_redirect(home_url('/account'));
      exit;
  } else {
     // wp_redirect(home_url());
      exit;
  }
?>

我已经尝试了很多次了..但它仍然抛出错误...我有 测试服务器的 curl 及其与其他文件的工作......任何人都可以 知道为什么这不起作用

每当我尝试 print_r th 响应时..它是空的并且什么都不显示

恢复对话：

• 您必须在您的证书上使用 realpath() 以确保它找到它。
• 自 2016 年 6 月 17 日起，Paypal 升级了其 API。您现在必须使用 TLS 1.2（CURLOPT_SSL_VERIFYHOST = 6 用于 cURL）（在此处查看更多信息：https://www.paypal-knowledge.com/infocenter/index?page=content&widgetview=true&id=FAQ1914&viewlocale=en_US）

  $tx = $_GET['tx'];
  $ID = $_GET['cm'];
  $amount = $_GET['amt'];
  $currency = $_GET['cc'];
  $auth = "#####";

  // Init cURL
  $ch = curl_init(); 

  // Set request options
  $url = 'https://www.sandbox.paypal.com/cgi-bin/webscr';
  $fields = array(
      'cmd' => '_notify-synch',
      'tx' => $tx,
      'at' => $auth
  );
  curl_setopt($ch,CURLOPT_SSL_VERIFYHOST, 6);   //force TLS 1.2
  curl_setopt($ch,CURLOPT_CAINFO, realpath('cacert.pem'));
  curl_setopt($ch,CURLOPT_URL, $url);
  curl_setopt($ch,CURLOPT_POST, count($fields));
  curl_setopt($ch,CURLOPT_POSTFIELDS, http_build_query($fields));
  curl_setopt($ch,CURLOPT_RETURNTRANSFER, TRUE);
  curl_setopt($ch,CURLOPT_HEADER, FALSE);

  // Execute request and get response and status code
  $response = curl_exec($ch);
  $status   = curl_getinfo($ch, CURLINFO_HTTP_CODE);

  // Close connection
  curl_close($ch);
  print_r($response);
  if($status == 200 AND strpos($response, 'SUCCESS') === 0)
  {
      //wp_redirect(home_url('/account'));
      exit;
  } else {
     // wp_redirect(home_url());
      exit;
  }
