Question

我使用Microsoft WF（https://msdn.microsoft.com/en-us/library/ff432975%28v=vs.110%29.aspx）

创建了一个Workflow服务

当我在visual studio中运行该服务时，我收到以下错误

Error: Cannot obtain Metadata from http://localhost/OrderService/Service1.xamlx

如果这是您有权访问的Windows（R）Communication Foundation服务，请检查您是否已在指定地址启用元数据发布。有关启用元数据发布的帮助，请参阅http://go.microsoft.com/fwlink/?LinkId=65455.WS-Metadata Exchange错误URI上的MSDN文档：http://localhost/OrderService/Service1.xamlx 元数据包含无法解析的引用：“http://localhost/OrderService/Service1.xamlx”。服务器没有提供有意义的回复;这可能是由于合同不匹配，过早的会话关闭或内部服务器错误引起的.HTTP GET错误URI：http://localhost/OrderService/Service1.xamlx 下载“http://localhost/OrderService/Service1.xamlx”时出错。请求因空响应而失败。

我的配置如下。我也在配置文件中添加了Meta Exchange行。

<system.serviceModel>
<services>
  <service behaviorConfiguration="metadataBehavior" name="MyService">
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
  </service>
</services>
<behaviors>      
  <serviceBehaviors>
    <behavior  name="metadataBehavior">
      <!-- To avoid disclosing metadata information, set the values below to false 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="true"/>
      <!--Connection String for the WF SQL Presistance-->
      <sqlWorkflowInstanceStore connectionString="Data Source=AAAAA;Initial Catalog=KK_SQLPersistenceStore;Asynchronous Processing=True" instanceEncodingOption="None" instanceCompletionAction="DeleteAll" instanceLockedExceptionAction="BasicRetry" hostLockRenewalPeriod="00:00:30" runnableInstancesDetectionPeriod="00:00:02" />
      <workflowIdle timeToUnload="0"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

Answer 1

尝试将您的端点地址更改为此 <endpoint address="http://localhost/OrderService/Service1.xamlx/mex" binding="mexHttpBinding" contract="IMetadataExchange" />

WF工作流服务错误无法从http：//localhost/OrderService/Service1.xamlx
