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

解决方案

1 配置IIS

网站->属性->目录安全性->身份验证方法: 同时选中”匿名访问”和”集成Windows身份验证”

 

2 配置WCF客户端的Config文件:

有3处地方: 1)security mode, 2)end point的behaviorConfiguration, 3)behaviors

<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding …>

                <readerQuotas … />             

                <security mode="TransportCredentialOnly">
                    <transport clientCredentialType="Windows" proxyCredentialType="Windows" realm="" />
                    <message clientCredentialType="UserName" algorithmSuite="Default" />
                </security>

            </binding>
        </basicHttpBinding>
    </bindings>

    <client>
        <endpoint ... behaviorConfiguration="ImpersonationBehavior"/>
    </client>

    <behaviors>
        <endpointBehaviors>
            <behavior name="ImpersonationBehavior">
                <clientCredentials>
                    <windows allowedImpersonationLevel="Impersonation"/>
                </clientCredentials>
            </behavior>
        </endpointBehaviors>
    </behaviors>

</system.serviceModel>
