php - PHP Curl certinfo为空

我在PHP中有一个脚本，向Web服务发出了curl请求。该请求是从安装了SSL的服务器发出的，而我发送的Web服务也也具有SSL。

 $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, "https://webservice.com?wsdl");
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_TIMEOUT, 60000);
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);//My post data
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
        curl_setopt($ch, CURLOPT_CAINFO, "../cacerts.pem");
        curl_setopt($ch, CURLOPT_CAPATH, "../cacerts.pem");
        $headers = [];
        array_push($headers, 'Content-Type: text/xml;charset=UTF-8');
        array_push($headers, 'SoapAction: *');
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        $content = trim(curl_exec($ch));
        var_dump($content);
        var_dump(curl_getinfo($ch));
        var_dump(curl_errno($ch));
        var_dump(curl_error($ch));
        curl_close($ch);

我得到的调试信息如下：

array (size=26)
  'url' => string 'https://webservice.com?wsdl' (length=42)
  'content_type' => string 'text/xml;charset=utf-8' (length=22)
  'http_code' => int 200
  'header_size' => int 165
  'request_size' => int 901
  'filetime' => int -1
  'ssl_verify_result' => int 0
  'redirect_count' => int 0
  'total_time' => float 1.469
  'namelookup_time' => float 0.25
  'connect_time' => float 0.688
  'pretransfer_time' => float 1.188
  'size_upload' => float 632
  'size_download' => float 536
  'speed_download' => float 364
  'speed_upload' => float 430
  'download_content_length' => float 536
  'upload_content_length' => float 632
  'starttransfer_time' => float 1.469
  'redirect_time' => float 0
  'redirect_url' => string '' (length=0)
  'primary_ip' => string 'xxx.xxx.xxx.xxx' (length=15)
  'certinfo' =>
    array (size=0)
      empty
  'primary_port' => int 443
  'local_ip' => string 'xx.xx.xx.x' (length=10)
  'local_port' => int 61993

“ certinfo”为空数组是否正常？如果不是，为什么它是空的。
谢谢。

最佳答案

您可能需要设置以下选项以填充“ certinfo”

curl_setopt($ch, CURLOPT_CERTINFO, 1);
