PHP curl certinfo为空

Question

我有一个PHP脚本，它向web服务发出curl请求。该请求是由我的服务器完成的，该服务器安装了SSL，并且我发送的Web服务请求也包含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); 

调试信息我得到的是波纹管：

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 

这是正常的“certinfo”是一个空数组？如果不是为什么它是空的。 谢谢。

您可能需要设置下列选项有“certinfo”填充

curl_setopt($ch, CURLOPT_CERTINFO, 1);
