我正在尝试将 workflowControlEndpoint 添加到我的 IIS 托管 XAMLX 服务中。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：未找到。元数据包含无法解析的引用：“http://localhost/Test.xamlx/wce”。内容类型应用程序/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'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。有人可以指出我缺少什么吗？感谢并感谢您的帮助....

我试图让 IWorkflowInstanceManagement 通过 WCF 测试客户端工作，但我永远无法让它找到元数据。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 如下所示：

<?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 > 程序和功能 > 打开或关闭 Windows 功能”并检查是否检查了以下功能：

  • .NET 框架 3.5
  • .NET Framework 4.5 高级服务 > WCF 服务
