wcf - HTTP 请求未经客户端身份验证方案 'Basic' 授权。从服务器收到的身份验证 header 是 'Negotiate,NTLM'

Question

我正在尝试使用以下设置连接到服务。

<bindings>
  <basicHttpBinding>
    <binding name="EngineSoap" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="2147483647" maxBufferPoolSize="524288" maxReceivedMessageSize="2147483647" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true">
      <readerQuotas maxDepth="32" maxStringContentLength="2147483647" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384"/>
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Basic" proxyCredentialType="None" realm=""/>
        <message clientCredentialType="UserName" algorithmSuite="Default"/>
      </security>
    </binding>
  </basicHttpBinding>
</bindings>
<client>
  <endpoint address="http://addressToService" binding="basicHttpBinding" bindingConfiguration="EngineSoap" contract="TRIMAPI.EngineSoap" name="EngineSoap" />
</client>

我得到的错误如下:

The HTTP request is unauthorized with client authentication scheme 'Basic'. The authentication header received from the server was 'Negotiate,NTLM'. ---> System.Net.WebException: The remote server returned an error: (401) Unauthorized.
   at System.Net.HttpWebRequest.GetResponse()
   at System.ServiceModel.Channels.HttpChannelFactory.HttpRequestChannel.HttpChannelRequest.WaitForReply(TimeSpan timeout)
   --- End of inner exception stack trace ---

   at System.ServiceModel.Channels.ServiceChannelProxy.InvokeService(IMethodCallMessage methodCall, ProxyOperationRuntime operation)
   at System.ServiceModel.Channels.ServiceChannelProxy.Invoke(IMessage message)

我试图将 clientCredentialType="Basic"更改为 "Windows"和 "Ntlm"但没有成功。我无法将安全模式设置为“TransportCredentialOnly”以外的任何模式，因为该服务不使用 SSL。

此外，用户名类似于“域\用户名”。

我错过了什么？

Answer 1

clientCredentialType 需要是 Ntlm 而不是 Basic

<bindings>
  <basicHttpBinding>
    <binding name="EngineSoap">
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Ntlm" proxyCredentialType="None" realm=""/>
      </security>
    </binding>
  </basicHttpBinding>
</bindings>

如果是 HTTPS/SSL 连接，则将 TransportCredentialOnly 更改为 Transport。参见 <transport> of <basicHttpBinding> 了解更多信息。
