我创建了一个WCF dataservice类来将查询结果返回给javascript客户端。这里是我的dataservice的伪代码:如何从wcf dataservice返回相关实体
public class MyDataService : DataService<MyEntities>
{
public static void InitializeService(DataServiceConfiguration config)
{
config.SetEntitySetAccessRule("*", EntitySetRights.All);
config.SetServiceOperationAccessRule("MyGetMethod", ServiceOperationRights.All);
config.DataServiceBehavior.MaxProtocolVersion = DataServicePRotocolVersion.V2;
}
[WebGet(UriTemplate = "{SomeID}"]
public IEnumerable<Models.Customer> MyGetMethod(int? someID)
{
if (someID == null) throw new DataServiceException("ID not specified");
MyEntities context = this.CurrentDataSource;
context.ContextOptions.LazyLoadingEnabled = false;
var q = Linq statement which queries for a collection of entities from context
IEnumerable<Models.Customer> result = q;
foreach (Models.Customer customer in result)
{
if (!customer.Contacts.IsLoaded)
customer.Contacts.Load();
}
return result;
}
}
来自客户端的调用请求导致json。当我调试dataservice中的get方法时,结果在一个名为WrappedRelatedEntities的属性中扩展了特定的相关数据,但是在返回给客户端的json中,它表示延期的相关实体。
我需要做些什么来让这些相关实体返回给客户端?谢谢!
