使用Core Service创建组件时出现故障状态错误

Question

在SDL Tridion 2011 SP1中使用Core Service时出现"故障状态"错误.以下是什么问题？

namespace coreservice1
{
      public partial class _Default : System.Web.UI.Page
      {
       protected void Page_Load(object sender, EventArgs e)
       {
        try
        {

            using (ChannelFactory<ISessionAwareCoreService> factory =
      new ChannelFactory<ISessionAwareCoreService>("wsHttp_2011"))
            {
                ISessionAwareCoreService client = factory.CreateChannel();
                string SCHEMA_URI = "tcm:7-426-8";

                var schemaFields = client.ReadSchemaFields(SCHEMA_URI, true, new ReadOptions());
                foreach (var field in schemaFields.Fields) 
                { 
                    Response.Write(string.Format("{0}", field.Name));                         
                } 
                Response.Write(schemaFields.NamespaceUri);
                string NEW_COMPONENT_FOLDER_URI = "tcm:8-15-2";

               Tridion.ContentManager.CoreService.Client.ComponentData component = new Tridion.ContentManager.CoreService.Client.ComponentData
               {
                   Schema = new LinkToSchemaData { IdRef = "tcm:8-426-8"},
                   Title = "Helloworldalll",
                   Id = "tcm:0-0-0",
                   LocationInfo = new LocationInfo
                   {
                       OrganizationalItem =
                           new LinkToOrganizationalItemData { IdRef = NEW_COMPONENT_FOLDER_URI}
                   },
               };

               string namespaceUri = schemaFields.NamespaceUri;
               System.Text.StringBuilder content = new StringBuilder();
               string First = "Hello World.This is Fisrt field";
               content.AppendFormat("<{0} xmlns=\"{1}\">", schemaFields.RootElementName, namespaceUri);
               content.AppendFormat("<{0} xmlns=\"{1}\">{2}</{0}>", "first", namespaceUri, First);
               content.AppendFormat("</{0}>", schemaFields.RootElementName);
               component.Content = content.ToString();
               ComponentData comp = (ComponentData)client.Create(component, new ReadOptions());
               string newlyCreatedComponentID = comp.Id;
               Response.Write("Hello hai");
               Response.Write("Id of newly created component: " + newlyCreatedComponentID);
            }

        }

        catch (Exception ex)
        {
            Response.Write(ex.StackTrace);
            Response.Write("exception is " + ex.Message);
        }

    }
  }
}

我认为这可能与您实例化客户端对象的方式有关.

您可以在Visual Studio中将其添加为服务引用:

例如,将服务引用添加到http:// {your tridion url} /webservices/CoreService.svc并为其指定TridionCoreService的命名空间,然后您可以像这样使用它:

TridionCoreService.CoreService2010Client client = new TridionCoreService.CoreService2010Client();   

或者,您可以使用此处的方法,该方法允许您创建Core Service引用而无需配置文件.
