贝宝PDT卷曲请求错误

Question

Below is the code for my paypal receive file for using paypal PDT

<?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;
  }
?>

I have tried many times now..but it is still throwing error...i have tested server for curl and its working with other file...can anyone has any idea why this is not working

Whenever i try to print_r th response ..its empty and show nothing

To resume the conversation :

• You have to use realpath() on your cert to be sure it finds it.
• Since 17th June 2016, Paypal upgraded its API. You have to use TLS 1.2 now (CURLOPT_SSL_VERIFYHOST = 6 for cURL use) (see more here : 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;
  }
?>
