我有一个在 Visual Studio 中运行的简单网络服务。如果我尝试查看元数据，它会丢失有关操作的信息，因此 svcutil 会生成没有任何方法的客户端代码。我的设置有什么问题吗？

    <system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="FCRPublishSOAP" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true">
                <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384"/>
                <security mode="None">
                    <transport clientCredentialType="None" proxyCredentialType="None" realm=""/>
                    <message clientCredentialType="UserName" algorithmSuite="Default"/>
                </security>
            </binding>
        </basicHttpBinding>
    </bindings>
    <services>
        <service name="Test.Publish.FCRPublish" behaviorConfiguration="SimpleServiceBehavior">
            <endpoint address="FCRPublish" behaviorConfiguration="" binding="basicHttpBinding" bindingConfiguration="FCRPublishSOAP" contract="IFCRPublish"/>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
  </service>
    </services>
<behaviors>
  <serviceBehaviors>
    <behavior name="SimpleServiceBehavior">
      <serviceMetadata httpGetEnabled="True" policyVersion="Policy15" />
    </behavior>
  </serviceBehaviors>
</behaviors>

接口(interface):

    [System.ServiceModel.ServiceContractAttribute(Namespace="http://Test/Publish", ConfigurationName="IFCRPublish")]
public interface IFCRPublish
{

    // CODEGEN: Generating message contract since the operation PublishNotification is neither RPC nor document wrapped.
    [System.ServiceModel.OperationContractAttribute(Action="http://Test/PublishNotification", ReplyAction="*")]
    PublishNotificationResponse1 PublishNotification(PublishNotificationRequest1 request);
}

响应:

    [System.Diagnostics.DebuggerStepThroughAttribute()]
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0")]
[System.ServiceModel.MessageContractAttribute(IsWrapped=false)]
public partial class PublishNotificationResponse1
{

    [System.ServiceModel.MessageBodyMemberAttribute(Namespace="http://Test/PublishTypes", Order=0)]
    public PublishNotificationResponse PublishNotificationResponse;

    public PublishNotificationResponse1()
    {
    }

    public PublishNotificationResponse1(PublishNotificationResponse PublishNotificationResponse)
    {
        this.PublishNotificationResponse = PublishNotificationResponse;
    }
}

要求:

    [System.Diagnostics.DebuggerStepThroughAttribute()]
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "3.0.0.0")]
[System.ServiceModel.MessageContractAttribute(IsWrapped=false)]
public partial class PublishNotificationRequest1
{

    [System.ServiceModel.MessageBodyMemberAttribute(Namespace="http://Test/PublishTypes", Order=0)]
    public PublishNotification PublishNotification;

    public PublishNotificationRequest1()
    {
    }

    public PublishNotificationRequest1(PublishNotification PublishNotification)
    {
        this.PublishNotification = PublishNotification;
    }
}

这是我收到的元数据:

<wsdl:import namespace="http://Test/Publish" location="http://localhost:3992/FCRPublish.svc?wsdl=wsdl0"/>
<wsdl:types/>
<wsdl:binding name="BasicHttpBinding_IFCRPublish" type="i0:IFCRPublish">
    <soap:binding transport="http://schemas.xmlsoap.org/soap/http"/>
</wsdl:binding>
<wsdl:service name="FCRPublish">
    <wsdl:port name="BasicHttpBinding_IFCRPublish" binding="tns:BasicHttpBinding_IFCRPublish">
        <soap:address location="http://localhost:3992/FCRPublish.svc"/>
    </wsdl:port>
</wsdl:service>

我的操作去哪儿了？

最佳答案

解决了。为 OperationContract 设置 ReplyAction="*"意味着 WsdlExporter(发布元数据)将忽略该操作。设置任何其他值都会修复它。

令我困扰的是，默认情况下 svcutil 会将 repodaction 设置为 *，这意味着默认情况下 svcutil 创建的服务的元数据已被有效破坏。

关于c# - WCF 元数据缺少操作，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/4214815/
