在哪里启用元数据(在配置中启用)?

mex exception-handling web-services wcf .net

GurdeepS · 技术社区 · 15 年前

我有一个基本的wcf服务,当我去wcftestclient测试它时,我得到一个错误,说找不到元数据,请添加它等。不幸的是,错误弹出窗口中的msdn链接断开,我的wcf服务的app.config启用了元数据:

  <serviceBehaviors>
    <behavior name="TelerikWcfServices.Service1Behavior">
      <!-- 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" />
    </behavior>
  </serviceBehaviors>

除此之外,我没有在代码中的任何其他地方更改任何元数据设置。

在哪里可以启用元数据来修复错误?

您需要向服务节点添加元数据交换(MEX)端点。尝试如下操作:

<endpoint 
    address="http://host/svc/mex" 
    binding="mexHttpBinding" 
    bindingConfiguration=""
    contract="IMetadataExchange"/>

如果将工作流4.0与WorkflowServiceHost一起使用并从XAMLX资源加载服务,则它将无法识别具有名称的WCF ServiceBehavior标记。我不知道为什么(在我看来像个虫子)。例如,上面的这个标签:

<serviceBehaviors>
    <behavior name="TelerikWcfServices.Service1Behavior">
      <serviceMetadata httpGetEnabled="True"/>
      <serviceDebug includeExceptionDetailInFaults="False" />
    </behavior>
  </serviceBehaviors>

需要像这样消除其名称属性:

<serviceBehaviors>
    <behavior>
      <serviceMetadata httpGetEnabled="True"/>
      <serviceDebug includeExceptionDetailInFaults="False" />
    </behavior>
  </serviceBehaviors>

服务元素将消除对行为配置名称的引用,如

<service 
    name="TelerikWcfServices.IScheduler">
    <endpoint address="http://localhost/Telerik" binding="basicHttpBinding"
      bindingConfiguration="" name="Telerik"      contract="TelerikWcfServices.IScheduler">...

我回答了自己的问题,因为这是显示整个文件的唯一简单方法:

<client>
  <endpoint address="http://localhost/Telerik" binding="basicHttpBinding"
    bindingConfiguration="" contract="TelerikWcfServices.IScheduler"
    name="Telerik">
    <identity>
      <dns value="localhost" />
      <certificateReference storeName="My" storeLocation="LocalMachine"
        x509FindType="FindBySubjectDistinguishedName" />
    </identity>
  </endpoint>
</client>
<diagnostics>
  <messageLogging logEntireMessage="true" />
</diagnostics>
<services>
  <service behaviorConfiguration="TelerikWcfServices.Service1Behavior"
    name="TelerikWcfServices.IScheduler">
    <endpoint address="http://localhost/Telerik" binding="basicHttpBinding"
      bindingConfiguration="" name="Telerik" contract="TelerikWcfServices.IScheduler">
      <identity>
        <dns value="localhost" />
      </identity>
    </endpoint>
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:8731/Design_Time_Addresses/TelerikWcfServices/Service1/" />
      </baseAddresses>
    </host>
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="TelerikWcfServices.Service1Behavior">
      <!-- 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" />
    </behavior>
  </serviceBehaviors>
</behaviors>

谢谢你的帮助!
