cURL 无法在本地服务器中使用客户端证书

我使用 XAMPP 设置了本地服务器。我有两个 PHP 脚本，一个发送者和一个接收者。我正在尝试使用 HTTP over SSL (HTTPS) 将 XML 文件从发送方发送到接收方。

我创建了一个自签名证书，配置了 XAMPP，并且我在发件人上使用此代码：

<?php
  /*
   * XML Sender/Client.
   */
  // Get our XML. You can declare it here or even load a file.


  $xml = file_get_contents("data.xml");

  // We send XML via CURL using POST with a http header of text/xml.
  $ch = curl_init();

  //curl_setopt($ch, CURLOPT_SSLVERSION,3);

  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
  curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);

  curl_setopt($ch, CURLOPT_CAINFO,  getcwd().'ipm.crt');
  curl_setopt($ch, CURLOPT_SSLCERT, getcwd().'ipm.pem');

  curl_setopt($ch, CURLOPT_SSLCERTPASSWD,'pass');

  //i use this line only for debugging through fiddler. Must delete after done with debugging.
  curl_setopt($ch, CURLOPT_PROXY, '127.0.0.1:8888');

  // set URL and other appropriate options
  curl_setopt($ch, CURLOPT_URL, "https://ipv4.fiddler/iPM/receiver.php");
  curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
  curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
  curl_setopt($ch, CURLOPT_REFERER, 'https://ipv4.fiddler/iPM/receiver.php');
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  $ch_result = curl_exec($ch);
  echo "Result = ".$ch_result;

  echo 'Curl error: ' . curl_error($ch);

  curl_close($ch);
  // Print CURL result.
?>

但是我总是收到这个错误：Curl error: unable to use client certificate (no key found or wrong pass phrase?)

我可能做错了什么？密码就是这个词pass .

我通过执行以下操作创建了 .crt：

openssl req -config openssl.cnf -new -out ipm.csr -keyout ipm.pem

openssl rsa -in ipm.pem -out ipm.key

openssl x509 -in ipm.csr -out ipm.crt -req -signkey ipm.key -days 365

我不想把SSL_VERIFYPEER and SSL_VERIFYHOST为假。

尝试像这样交换文件：

curl_setopt($ch, CURLOPT_CAINFO, getcwd().'ipm.pem');
curl_setopt($ch, CURLOPT_SSLCERT, getcwd().'ipm.crt');

我怀疑你把它们搞错了。
