.NET Core 上的 WCF 在授权方案中缺少客户端协商方案答案

【问题标题】：WCF on .NET Core missing client Negotiate scheme in authorization scheme.NET Core 上的 WCF 在授权方案中缺少客户端协商方案

【问题描述】：

将 WCF 服务和 ASP.NET Core 网站移至服务器后，出现以下错误：

The HTTP request is unauthorized with client authentication scheme 'Ntlm'. The authentication header received from the server was 'Negotiate, NTLM'.

我已使用以下 web.config 仅在 WCF 服务上启用了 Windows 身份验证：

<system.serviceModel>
    <client />
    <behaviors>
      <serviceBehaviors>
        <behavior name="authBehavior">
          <serviceAuthorization principalPermissionMode="UseWindowsGroups">
            <authorizationPolicies>
              <add policyType="WCF.AuthorizationPolicy, WCF" />
            </authorizationPolicies>
          </serviceAuthorization>
          <serviceCredentials>
            <userNameAuthentication userNamePasswordValidationMode="Custom" customUserNamePasswordValidatorType="WCF.IdentityValidator, WCF" />
            <serviceCertificate findValue="16E86CCAFFE6211DAE6E841B984F71FB7609D349" storeLocation="LocalMachine" x509FindType="FindBySerialNumber" storeName="My" />
          </serviceCredentials>
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <bindings>
      <basicHttpsBinding>
        <binding name="basicHttpsEndpointBinding" maxReceivedMessageSize="1073741824" maxBufferSize="1073741824" maxBufferPoolSize="1073741824">
          <readerQuotas maxDepth="32" maxArrayLength="1073741824" maxStringContentLength="1073741824" />
          <security mode="Transport">
            <transport clientCredentialType="Ntlm" />
          </security>
        </binding>
      </basicHttpsBinding>
    </bindings>
    <services>
      <service name="WCF.MyService" behaviorConfiguration="authBehavior">
        <endpoint address="" binding="basicHttpsBinding" bindingConfiguration="basicHttpsEndpointBinding" contract="WCF.IMyService">
          <identity>
            <dns value="example.com" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
      </service>
    </services>

ASP.NET Core 客户端：

BasicHttpsBinding binding = new BasicHttpsBinding
   {
        MaxBufferPoolSize = 1073741824,
        MaxBufferSize = 1073741824,
        MaxReceivedMessageSize = 1073741824
   };
   binding.ReaderQuotas.MaxDepth = 32;
   binding.ReaderQuotas.MaxArrayLength = 1073741824;
   binding.ReaderQuotas.MaxStringContentLength = 1073741824;
   binding.Security.Mode = BasicHttpsSecurityMode.Transport;
   binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Ntlm;

   MyServiceClient client = new MyServiceClient(binding, new EndpointAddress(new Uri("https://example.com/MyService.svc"), new DnsEndpointIdentity("mydomain.com")));
   client.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;

   client.ClientCredentials.Windows.ClientCredential.Domain = Configuration.GetSection("WCF")["MyServiceDomain"];
   client.ClientCredentials.Windows.ClientCredential.UserName = Configuration.GetSection("WCF")["MyServiceUserName"];
   client.ClientCredentials.Windows.ClientCredential.Password = Configuration.GetSection("WCF")["MyServicePassword"];

   // client call

我想不出什么是错的。如果我在配置/代码中将 Ntlm 更改为 Windows，则客户端身份验证方案“协商”会出错。我是否可以同时使用两者，或者我必须以某种方式从 IIS 中删除 Negotiate/Ntlm？

感谢您的任何想法！

需要重启服务器！

您可能会发现this post 很有见地。
好吧，如果另一个项目已经编写并且它可以在 localhost 但不能在服务器上运行，那就太糟糕了：D 无论如何我通过阅读文章解决了问题：blogs.msdn.microsoft.com/distributedservices/2009/11/10/… 这解决了我的问题
将解决方案发布为答案并接受。
当然.. 我只需要等待 2 天就可以接受它：D

使用方法一，需要重启服务器！

在注册表中我使用 CNAME 之类的

mySubdomain
mySubdomain.myDomain.com
localhost
192.168.0.xxx
192.168.0.1 (default gateway)
xx.xx.xx.xx (my ip address)
