Question

我正在尝试将workflowControlEndpoint添加到我的IIS托管XAMLX服务。我无法从客户端引用控制端点，我不断收到以下错误

请求失败，HTTP状态为404：Not Found。元数据包含无法解析的引用：'http：//localhost/Test.xamlx/wce'。内容类型application / soap + xml;服务'http：//mymachine/Test.xamlx/wce'不支持charset = utf-8。客户端和服务绑定可能不匹配。远程服务器返回错误：（415）无法处理消息，因为内容类型为'application / soap + xml; charset = utf-8'不是预期的类型'text / xml;字符集= UTF-8' ..

我有以下web.config。有人能指出我错过了什么吗？谢谢，感谢帮助......

Answer 1

我试图让IWorkflowInstanceManagement通过WCF测试客户端工作，但我从来没有找到它来查找元数据。所以我只是尝试通过代码与它进行通信。它对我有用。

我创建了一个新的Workflow Service项目，我的web.config看起来像这样：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>

  <connectionStrings>
    <add name="ApplicationServices" connectionString="data source=localhost\SQLEXPRESS;Initial Catalog=WFS;Integrated Security=True" providerName="System.Data.SqlClient" />
  </connectionStrings>

  <system.serviceModel>

    <behaviors>
      <serviceBehaviors>
        <behavior name="workflowBehavior">
          <serviceMetadata httpGetEnabled="True" />
          <serviceDebug includeExceptionDetailInFaults="true" />
          <sqlWorkflowInstanceStore instanceCompletionAction="DeleteAll" 
                                    instanceEncodingOption="GZip" 
                                    instanceLockedExceptionAction="BasicRetry" 
                                    connectionStringName="ApplicationServices" 
                                    hostLockRenewalPeriod="00:00:20" 
                                    runnableInstancesDetectionPeriod="00:00:05" />
          <workflowInstanceManagement authorizedWindowsGroup="AS_Administrators" />
          <workflowUnhandledException action="Terminate" />
          <workflowIdle timeToPersist="00:01:00" timeToUnload="00:01:00" />
        </behavior>

        <behavior name="wceBehavior">
          <serviceMetadata httpGetEnabled="True" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>

    </behaviors>

    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" />

    <services>
      <service name="Service1" behaviorConfiguration="workflowBehavior">
        <endpoint binding="basicHttpBinding" address="" contract="IService" />
        <endpoint binding="basicHttpBinding" address="wce" kind="workflowControlEndpoint" />
      </service>
    </services>
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>
</configuration>

然后我使用以下代码创建了一个控制台应用程序（我知道这不是使用ChannelFactory的最佳方式）：

var binding = new BasicHttpBinding(BasicHttpSecurityMode.None);
var channelFactory = new ChannelFactory<IWorkflowInstanceManagement>(binding);
var channel = channelFactory.CreateChannel(new EndpointAddress("http://localhost/WorkflowControlTest/Service1.xamlx/wce"));
channel.Cancel(new Guid("DE212DE0-6BFF-4096-BF30-F6ACB2923B50"));

我的工作流程只是在一个运行延迟几分钟的循环中运行。我能够通过WCF测试客户端启动工作流实例，然后从持久性数据库中获取工作流实例ID，然后运行控制台应用程序以取消工作流。

转到“控制面板＆gt;程序和功能＆gt;打开或关闭Windows功能”，然后检查是否选中了以下功能：

.NET Framework 3.5
.NET Framework 4.5高级服务＆gt; WCF服务

WF 4.0将WorkflowControlEndPoint添加到IIS托管的XAMLX服务
