通过ASP.NET 2.0网站使用WCF服务（证书身份验证）

Question

我创建了一个带有证书身份验证的WCF服务，它与WCF客户端完美配合。但问题是当我想通过WebService客户端使用相同的WCF服务时（可能客户端可能只有.net 2.0框架）。

我试图调用的WCF服务方法是

public class Service : IService
 {
    public string GetWelcomeMessage()
    {
        return "Consuming WCF Service as Webservice";
    }
 }

我的WCF服务配置片段如下

<system.serviceModel>
    <services>
        <service name="Service" behaviorConfiguration="ServiceBehavior">
            <!-- Service Endpoints -->
            <endpoint name="BasicHttpEndPoint" address="" binding="basicHttpBinding" contract="IService" bindingConfiguration="BasicHttpEndPointBinding">
                <!-- 
          Upon deployment, the following identity element should be removed or replaced to reflect the 
          identity under which the deployed service runs.  If removed, WCF will infer an appropriate identity 
          automatically.
      -->
                <identity>
                    <dns value="localhost"/>
                </identity>
            </endpoint>
            <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
        </service>
    </services>
    <bindings>
        <basicHttpBinding>
            <binding name="BasicHttpEndPointBinding">
                <security mode="Message">
                    <message clientCredentialType="Certificate"/>
                </security>
            </binding>
        </basicHttpBinding>
    </bindings>
    <behaviors>
        <serviceBehaviors>
            <behavior name="ServiceBehavior">
                <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
                <serviceMetadata httpGetEnabled="true"/>
                <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
                <serviceDebug includeExceptionDetailInFaults="false"/>
                <serviceCredentials>
                    <serviceCertificate findValue="CN=tempServerCert"/>
        <!--<clientCertificate>
          <authentication certificateValidationMode="ChainTrust"/>
        </clientCertificate>-->
                </serviceCredentials>
            </behavior>
        </serviceBehaviors>
    </behaviors>
</system.serviceModel>

我已在VS2005上创建的ASP.Net 2.0应用程序中添加了WCF服务作为“添加Web Referance”，而我的客户端（ASP.net 2.0应用程序）web.config是

<system.serviceModel>
    <services>
        <service name="Service" behaviorConfiguration="ServiceBehavior">
            <!-- Service Endpoints -->
            <endpoint name="BasicHttpEndPoint" address="" binding="basicHttpBinding" contract="IService" bindingConfiguration="BasicHttpEndPointBinding">
                <!-- 
          Upon deployment, the following identity element should be removed or replaced to reflect the 
          identity under which the deployed service runs.  If removed, WCF will infer an appropriate identity 
          automatically.
      -->
                <identity>
                    <dns value="localhost"/>
                </identity>
            </endpoint>
            <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
        </service>
    </services>
    <bindings>
        <basicHttpBinding>
            <binding name="BasicHttpEndPointBinding">
                <security mode="Message">
                    <message clientCredentialType="Certificate"/>
                </security>
            </binding>
        </basicHttpBinding>
    </bindings>
    <behaviors>
        <serviceBehaviors>
            <behavior name="ServiceBehavior">
                <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
                <serviceMetadata httpGetEnabled="true"/>
                <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
                <serviceDebug includeExceptionDetailInFaults="false"/>
                <serviceCredentials>
                    <serviceCertificate findValue="CN=tempServerCert"/>
        <!--<clientCertificate>
          <authentication certificateValidationMode="ChainTrust"/>
        </clientCertificate>-->
                </serviceCredentials>
            </behavior>
        </serviceBehaviors>
    </behaviors>
</system.serviceModel>

我在调用WCF服务时收到SoapHandlerException。例外情况如下

Message:        An error occurred when verifying security for the message.
