Silverlight WCF抛出远程服务器返回一个错误:NotFound

本文关键字:一个 错误 NotFound 返回 WCF 服务器 Silverlight | 更新日期: 2023-09-27 18:08:25

我想弄清楚为什么会发生这种情况。这太奇怪了

以下是我的确切呼叫。每当我在车辆数据合约的末尾添加额外的数据时,我得到远程服务器返回一个错误:NotFound。打电话时选择。SaveVehiclesAsync (infoKey、数据);

From Silverlight Side

public void SaveVehicles(InfoKey infoKey, ObservableCollection<VehicleFullInfoModel> vehicleFullInfoCollection, EventHandler<SaveVehiclesEventArgs> callBack)
    {
        var pick = new **ProjectServiceClient**();
        pick.SaveVehiclesCompleted += (sender, e) =>
        {
            if (callBack != null)
                callBack(this, new SaveVehiclesEventArgs(e.Result, e.fault));
        };
        var data =
            new ObservableCollection<VehicleFullInfo>(vehicleFullInfoCollection.Select(rec => rec.Data).ToList());
        pick.SaveVehiclesAsync(infoKey, data);
    }

-------------来自WCF服务

public interface IProjectService
{
    [OperationContract]
    string SaveVehicles(InfoKey infoKey, IList<VehicleFullInfo> vehicleFullInfoCollection, out FaultContract fault);
}
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class ProjectService : IProjectService
{
    public string SaveVehicles(InfoKey infoKey, IList<VehicleFullInfo> vehicleFullInfoCollection, out FaultContract fault)
    {      
        return PickVehicles.SaveVehicles(infoKey, vehicleFullInfoCollection,  out fault);
    }
}

Silverlight WCF抛出远程服务器返回一个错误:NotFound

Not Found是Silverlight上的一个通用错误,这可能意味着很多事情-跨域问题,任何来自网络的非200响应等。您可以做一些事情,例如在服务器端启用跟踪,或者使用Fiddler等工具查看网络流量,这些工具将为您提供有关错误的更多信息。

http://blogs.msdn.com/b/silverlightws/archive/2008/04/16/debugging-web-service-usage-in-silverlight-2.aspx上的帖子有一些信息,这些信息在调试Silverlight的WCF调用时很有用。

大多数时候发生这种错误,只需右键单击ASP。. NET IIS服务器图标,每次运行应用程序时在时钟附近打开并停止它。

尝试在服务器配置文件的末尾设置绑定配置-示例:

 <endpoint
           address=""
           binding="pollingDuplexHttpBinding"
           bindingConfiguration="multipleMessagesPerPollPollingDuplexHttpBinding"
           contract="DuplexService.IDuplexService">
</endpoint>

,当然你必须配置一个相应的绑定——比如:

<bindings>
        <pollingDuplexHttpBinding>
          <binding name="multipleMessagesPerPollPollingDuplexHttpBinding"
                   duplexMode="MultipleMessagesPerPoll"
                   maxOutputDelay="00:00:07"/>
        </pollingDuplexHttpBinding>
</bindings>

好运。

确保您的wcf已启用跟踪。这通常是导致我出现问题的原因,这次也是如此。
