我有一个由以下ServiceContract定义的简单WCF服务:
[ServiceContract]
public interface IInventoryService
{
[OperationContract]
Item GetItemFromBarcode(string barcode);
[OperationContract]
string Test(string testString);
}
使用如下定义的项目:
[DataContract]
public class Item
{
[DataMember]
public virtual int Id { get; set; }
<Snip>
}
实际服务如此实施:
public class InventoryService : IInventoryService
{
[WebGet(UriTemplate = "/Barcode/{barcode}/Item", ResponseFormat = WebMessageFormat.Json)]
public Item GetItemFromBarcode(string barcode)
{
var item = (from b in repository.Query<ItemBarcode>()
where b.BarcodeData == barcode
select b.Item).FirstOrDefault();
return item;
}
[WebGet(UriTemplate = "/Test/{testString}",ResponseFormat=WebMessageFormat.Xml)]
public string Test(string testString)
{
return testString;
}
}
在托管服务的程序的app.config中有以下内容:
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="true"/>
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="RESTFriendly">
<webHttp />
</behavior>
</endpointBehaviors>
</behaviors>
<services>
<service name="InventoryService">
<endpoint address="/Inventory" behaviorConfiguration="RESTFriendly" binding="webHttpBinding" contract="IInventoryService"/>
<host>
<baseAddresses>
<add baseAddress="http://localhost:8080/"/>
</baseAddresses>
</host>
</service>
</services>
</system.serviceModel>
现在代码转储已经完成了,问题是:我可以使用curl或Fiddler调用Test
方法,它会返回一个序列化的字符串。但是,调用返回对象的方法不会返回任何内容。 Curl吐回curl: (56) Failure when receiving data from the peer
,Fiddler回复ReadResponse() failed: The server did not return a response for this request.
从我读到的,这应该是Just Work(tm)。有什么明显的东西我不见了吗?
答案 0 :(得分:1)
因此,您似乎不能拥有DataMember
的接口类型,例如IList<ItemBarcode>
。我希望将我的NHibernate模型对象用作DTO。
