访问Web服务和HTTP接口使用证书认证(Accessing a web service and a

2019-06-25 16:07发布

这是我第一次使用证书认证。 商业合作伙伴公开两个服务,一个XML Web服务和HTTP服务。 我有一个.NET客户端来访问他们两个。

我曾尝试

0设置环境

我已经安装了SSLCACertificates(根和两个中间)和客户端证书在我的本地机器使用certmgr.exe(胜7专业)。

1.对于Web服务

  • 我有客户证书(DER)。
  • 该服务将通过.NET代理消耗。

下面的代码:

OrderWSService proxy = new OrderWSService();
string CertFile = "ClientCert_DER.cer";

proxy.ClientCertificates.Add(new System.Security.Cryptography.X509Certificates.X509Certificate(CertFile));
orderTrackingTO ot = new orderTrackingTO() { order_id = "80", tracking_id = "82", status = stateOrderType.IN_PREPARATION };
resultResponseTO res = proxy.insertOrderTracking(ot);

异常报告最后声明: The request failed with an empty response

2.对于HTTP接口

  • 它是一个HTTPS接口I必须通过POST方法来调用。
  • 该HTTPS请求从.NET客户端使用的HttpWebRequest来发送。

下面的代码:

string PostData = "MyPostData";

//setting the request
HttpWebRequest req;
req = (HttpWebRequest)HttpWebRequest.Create(url);
req.UserAgent = "MyUserAgent";
req.Method = "POST";
req.ContentType = "application/x-www-form-urlencoded";
req.ClientCertificates.Add(new System.Security.Cryptography.X509Certificates.X509Certificate(CertFile, "MyPassword")); 

//setting the request content
byte[] byteArray = Encoding.UTF8.GetBytes(PostData);
Stream dataStream = req.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();

//obtaining the response
WebResponse res = req.GetResponse();
r = new StreamReader(res.GetResponseStream());

异常报告最后声明: The request was aborted: Could not create SSL/TLS secure channel

3.最后一次尝试:使用浏览器

在Chrome中,将证书安装后,如果我尝试访问这两个URL我得到一个107错误:

Error 107 (net::ERR_SSL_PROTOCOL_ERROR)

我卡住了。

Answer 1:

以下应该可以帮助您找出问题,这里有两个方法来测试SSL连接的一个测试网站,而另一种是回调方法,以确定为什么SSL失败。 如果不出意外,应该给你一个更好的主意,为什么它是失败的。

当方法被调用它会弹出选择证书对话框,很明显,当你这样做的真正的,你会想从证书存储自动读取。 我已经把这个中的原因是因为,如果没有找到有效证书,然后你就会知道你的问题是在安装证书的方式。

做的最好的事情就是把这个代码在一个简单的控制台应用程序:

using System.Security.Cryptography.X509Certificates;
using System.Net.Security;
using System.Net;

private static void CheckSite(string url, string method)
{
    X509Certificate2 cert = null;
    ServicePointManager.ServerCertificateValidationCallback += ValidateRemoteCertificate;

    X509Store store = new X509Store(StoreLocation.LocalMachine);
    store.Open(OpenFlags.ReadOnly | OpenFlags.OpenExistingOnly);
    X509Certificate2Collection certcollection = (X509Certificate2Collection)store.Certificates;
    // pick a certificate from the store
    cert = X509Certificate2UI.SelectFromCollection(certcollection, 
            "Caption",
            "Message", X509SelectionFlag.SingleSelection)[0];

    store.Close();

    HttpWebRequest ws = (HttpWebRequest)WebRequest.Create(url);
    ws.Credentials = CredentialCache.DefaultCredentials;
    ws.Method = method;
    if (cert != null)
        ws.ClientCertificates.Add(cert);

    using (HttpWebResponse webResponse = (HttpWebResponse)ws.GetResponse())
    {
        using (Stream responseStream = webResponse.GetResponseStream())
        {
            using (StreamReader responseStreamReader = new StreamReader(responseStream, true))
            {
                string response = responseStreamReader.ReadToEnd();
                Console.WriteLine(response);
                responseStreamReader.Close();
            }

            responseStream.Close();
        }
        webResponse.Close();
    }
}

/// <summary>
/// Certificate validation callback.
/// </summary>
private static bool ValidateRemoteCertificate(object sender, X509Certificate cert, X509Chain chain, SslPolicyErrors error)
{
    // If the certificate is a valid, signed certificate, return true.
    if (error == System.Net.Security.SslPolicyErrors.None)
    {
        return true;
    }

    Console.WriteLine("X509Certificate [{0}] Policy Error: '{1}'",
        cert.Subject,
        error.ToString());

    return false;
}
