[英]Connecting to a Web Service using Client Certificate authentication
我一直在使用客户端证书身份验证通过SSL连接到Web服务的.p12文件。 我使用cURL成功地在PHP中工作。 这些是我在执行请求时使用的选项:
$headers = array(
'Method: POST',
'Connection: Keep-Alive',
'User-Agent: PHP-SOAP-CURL',
'Content-Type: text/xml; charset=utf-8',
'SOAPAction: "'.$action.'"',
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $location);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $request);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_FAILONERROR, 1);
curl_setopt($ch, CURLOPT_SSLCERT, $this->clientcert);
curl_setopt($ch, CURLOPT_SSLKEYTYPE, $this->clientcerttype);
curl_setopt($ch, CURLOPT_SSLKEY, $this->keyfile);
curl_setopt($ch, CURLOPT_SSLKEYPASSWD, $this->keypassword);
curl_setopt($ch, CURLOPT_SSLVERSION, 3);
$response = curl_exec($ch);
我现在正在尝试使用C#和.NET执行相同的任务,但我不断收到错误“无法建立具有权限的SSL / TLS的安全通道:'。”。
我似乎没有找到密钥的问题,似乎没有任何信任问题。 然而,某些事情是不对的,在某个地方。
我做了一个测试程序,这样我就可以测试一个基本的调用是否有效。
public void StartviaWSHttp()
{
var binding = new WSHttpBinding();
binding.Security.Mode = SecurityMode.Transport;
binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
binding.Security.Message.NegotiateServiceCredential = false;
binding.Security.Message.ClientCredentialType = MessageCredentialType.None;
var baseAddress = new Uri("https://<host>:<port>/LineEndpoint1");
var endpointAddress = new EndpointAddress(baseAddress);
var client = new LinePortTypeClient(binding, endpointAddress);
client.ClientCredentials.ClientCertificate.SetCertificate(StoreLocation.CurrentUser, StoreName.My, X509FindType.FindBySerialNumber, "00d48a233bf4b77523");
Debug.Assert(client.ClientCredentials.ClientCertificate.Certificate.SerialNumber.ToLower() == "00d48a233bf4b77523");
var header = new ctSoapHeaderMsg();
var response = new object();
client.Open();
var responseCode = client.PerformFunction(ref header, "0893411111", out response);
client.Close();
Console.WriteLine("Response Code :" + responseCode);
Console.WriteLine("Response :" + response);
}
当我在当前用户的个人/证书中查看证书时,它不会报告任何与信任有关的问题。 在证书信息中,它表示该证书用于以下目的:所有颁发策略和所有应用程序策略。 证书路径只有一个条目,证书状态报告“此证书正常”。
我对这个问题感到茫然。 也许存在信任问题,因为我已经关闭了PHP调用的PEER和HOST验证。 我不确定这是否是C#的选项。
更新:(2013年8月9日)我为System.Net和System.Net.Socket设置了一些详细的跟踪。 这是输出的开始。

表明没有证书被提取使用,即使我已将证书附加到client.ClientCredentials.ClientCertificate,但我不确定为什么会发生这种情况或如何使它坚持下去。 证书的任何属性是否必须与我要连接的主机名相匹配?
看来服务器不了解TLS。
我不得不指定SSLv3,via
System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Ssl3;
正如@ajeh在评论中提到的“transport clientCredentialType = ...”为我工作!
<binding name=".....">
<security mode="Transport" >
<transport clientCredentialType="Certificate"></transport>
</security>
</binding>
此外,您需要确保您的IIS应用程序池用户有权读取证书的私钥。
