无法使用 C# 和摘要身份验证连接到 TLS Web 服务，Firefox 成功，而 IE8 失败

Question

我尝试使用 C# 和摘要身份验证连接到 Web 服务，但每次都会收到 401 - Not Authorized 错误。但当我尝试通过 Firefox 访问该服务时，一切正常。当我使用 IE8 时，我的密码不被接受，并且出现 401。

您有什么想法吗？感谢您的帮助。

这是我正在使用的测试代码：

    ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls;
    ServicePointManager.ServerCertificateValidationCallback 
        = delegate(object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { return true; };

    Uri uri = new Uri(URL);

    NetworkCredential netCredential = new NetworkCredential(username, password);
    CredentialCache cache = new CredentialCache();
    cache.Add(URL, 443, "Digest", netCredential);

    WebRequest request = WebRequest.Create(URL);
    request.Credentials = cache;
    request.PreAuthenticate = true;
    request.Method = "POST";

    WebResponse response;

    try
    {
        response = request.GetResponse();
        Stream stream = response.GetResponseStream();
        StreamReader reader = new StreamReader(stream);
        string result = reader.ReadToEnd();
        Response.Write(result);
        response.Close();
        reader.Close();
    }
    catch (Exception ex)
    {
        Response.Write("Error: " + ex.Message + "<br/><br/><br/>");
        Response.Write("Request Headers<br/><br/>");

        WebHeaderCollection headers = request.Headers;

        // Get each header and display each value.
        foreach (string key in headers.AllKeys)
        {
            string value = headers[key];
            Response.Write(key + ": " + value);

            Response.Write("<br/><br/>");
        }

    }

您正在使用CredentialCache.Add的错误重载< /a>，您应该使用 CredentialCache.Add(Uri, string, NetworkCredential） 相反。第一个（带有端口号）仅适用于 SMTP。

cache.Add(uri, "Digest", netCredential);
