HTTP请求未经过客户端验证方案“Basic”进行授权。从服务器收到的身份验证标头为“Negotiate，NTLM”。

Question

我正在尝试使用以下设置连接到一个服务。

<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>

我收到的错误信息如下：

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)

我尝试将clientCredentialType="Basic"更改为“Windows”和“Ntlm”，但都没有成功。由于该服务未使用SSL，因此我无法将安全模式设置为除“TransportCredentialOnly”以外的任何其他模式。

此外，用户名类似于“domain\username”。

我错过了什么？

看看这个帖子，它可能会对你有所帮助。 - Lukas Kubis

@LukasKubis 尝试过了，但不起作用。 - h-rai

@nick-s 你有这方面的任何更新吗？ - DanielV

@DanielV 你尝试检查服务主机是否启用了“基本身份验证”吗？ - h-rai

@nick-s 谢谢你的更新，但问题与身份验证方法本身无关，而是与网络用户有关。 - DanielV

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。有关详细信息，请参见<basicHttpBinding>的<transport>。

Answer 2

服务器（IIS）上托管服务的基本身份验证未启用。启用它可以解决我的问题。
