c# - (WCF) 调用者未通过服务的身份验证

问题描述

我已经创建了 WCF 服务 + 客户端并将服务部署到另一台 PC。服务正在运行。但是，当我通过 Visual Studio 在调试模式下执行客户端时，我收到错误消息：调用者未通过服务进行身份验证。PC、客户端和服务器都在同一个本地网络上。

服务器端（服务）

    <?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <services>
      <!-- This section is optional with the new configuration model  
           introduced in .NET Framework 4. -->
      <service name="Digiteq.Services.LabSat.LabSatService"
               behaviorConfiguration="LabSatServiceBehavior">
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8000/LabSat3/service"/>
          </baseAddresses>
        </host>
        <!-- this endpoint is exposed at the base address provided by host: http://localhost:8733/LabSat/service  -->
        <endpoint address=""
                  binding="wsHttpBinding"
                  contract="Digiteq.Services.LabSat.ILabSat" />
        <!-- the mex endpoint is exposed at http://localhost:8733/LabSat3/service/mex -->
        <endpoint address="mex"
                  binding="mexHttpBinding"
                  contract="IMetadataExchange" />
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="LabSatServiceBehavior">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="False"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

客户端配置文件：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.serviceModel>
    <bindings>
      <wsHttpBinding>
        <binding name="WSHttpBinding_ILabSat" closeTimeout="00:01:00"
            openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
            bypassProxyOnLocal="false" transactionFlow="false" hostNameComparisonMode="StrongWildcard"

          </security>
        </binding>
      </wsHttpBinding>
    </bindings>
    <client>
      <endpoint address="http://192.168.228.65:8000/LabSat3/service" binding="wsHttpBinding"
          bindingConfiguration="WSHttpBinding_ILabSat" contract="ILabSat"
          name="WSHttpBinding_ILabSat">
        <identity>
          <servicePrincipalName value="host/MBO-NEW" />
        </identity>
      </endpoint>
    </client>
  </system.serviceModel>
</configuration>

解决方案

我认为问题可能是由客户端凭据引起的。据我所知，wsHttpBinding传输安全模式默认为Message，而我们设置传输安全为message时，客户端凭证类型默认为windows。所以我们需要明确提供可以被服务器端认证的凭证。 

client.ClientCredentials.Windows.ClientCredential.UserName = "username";
   client.ClientCredentials.Windows.ClientCredential.Password = "password";

这里是官方文档。 官方文件

也有可能是服务端需要标识，然后客户端需要手动指定endpointidentity。这取决于您的配置和托管环境。 官方文件
