Rad*_*ski 23 php ssl https curl
我希望能够使用CURL读取SSL证书信息.从Linux控制台我得到这个响应头:
GET https://www.google.com/ -ed

Title: Google
X-XSS-Protection: 1; mode=block
但是使用CURL,标题要短得多:
HTTP/1.1 200 OK

Expires: -1
Cache-Control: private, max-age=0

Server: gws
X-XSS-Protection: 1; mode=block
Transfer-Encoding: chunked
是否有可能获得这些信息,CURL的完整标题或其他一些PHP函数？

您将使用证书获取证书stream_context_get_params.将该资源插入$certinfo = openssl_x509_parse($cert['options']['ssl']['peer_certificate']);以获取更多证书信息.
$url = "http://www.google.com";
$orignal_parse = parse_url($url, PHP_URL_HOST);
$get = stream_context_create(array("ssl" => array("capture_peer_cert" => TRUE)));
$read = stream_socket_client("ssl://".$orignal_parse.":443", $errno, $errstr, 30, STREAM_CLIENT_CONNECT, $get);
$cert = stream_context_get_params($read);
$certinfo = openssl_x509_parse($cert['options']['ssl']['peer_certificate']);
print_r($certinfo);

号编辑:一个CURLINFO_CERTINFO选项已被添加到PHP 5.3.2.见http://bugs.php.net/49253
显然,您的代理在响应标头中提供了这些信息.如果你想依靠这一点,你可以用卷曲的CURLOPT_HEADER选项,以true包括在输出中的标头.
但是,要在不依赖某些代理的情况下检索证书,您必须这样做
<?php
$g = stream_context_create (array("ssl" => array("capture_peer_cert" => true)));
$r = fopen("https://www.google.com/", "rb", false, $g);
$cont = stream_context_get_params($r);
var_dump($cont["options"]["ssl"]["peer_certificate"]);
您可以$cont["options"]["ssl"]["peer_certificate"]使用OpenSSL扩展来操纵值.
编辑:此选项更好,因为它实际上不会发出HTTP请求,并且不需要allow_url_fopen:
<?php
$g = stream_context_create (array("ssl" => array("capture_peer_cert" => true)));
$r = stream_socket_client("ssl://www.google.com:443", $errno, $errstr, 30,
STREAM_CLIENT_CONNECT, $g);
$cont = stream_context_get_params($r);
var_dump($cont["options"]["ssl"]["peer_certificate"]);

要在php和curl中执行此操作:
<?php
if($fp = tmpfile())
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"https://www.digicert.com/");
curl_setopt($ch, CURLOPT_STDERR, $fp);
curl_setopt($ch, CURLOPT_CERTINFO, 1);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_NOBODY, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
$result = curl_exec($ch);
curl_errno($ch)==0 or die("Error:".curl_errno($ch)." ".curl_error($ch));
fseek($fp, 0);//rewind
$str='';
while(strlen($str.=fread($fp,8192))==8192);
echo $str;
fclose($fp);
}
?>
此代码片段并未专门使用 curl，但它检索并打印远程证书文本（可以使用各种 openssl_ 函数进行操作以返回您想要的任何详细信息）
$g = stream_context_create (array("ssl" => array("capture_peer_cert" => true)));
$r = fopen("https://somesite/my/path/", "rb", false, $g);
$cont = stream_context_get_params($r);
openssl_x509_export($cont["options"]["ssl"]["peer_certificate"],$cert);
print $cert;
输出：
-----BEGIN CERTIFICATE-----
...certificate content...
-----END CERTIFICATE-----
