c# - 您可以声明 2 个同名的 OData 资源实体集吗？

Question

如何声明两个具有相同名称但路由到不同区域的 OData EntitySet？这可能吗？

例如:

public static void Register(HttpConfiguration config)
{
   var builder = new ODataConventionModelBuilder();
   builder.EntitySet<Costco.Models.Food>("Foods");
   builder.EntitySet<Ikea.Models.Food>("Foods"); // this causes an exception
   config.Routes.MapODataServiceRoute("MyRoute", "{area}", builder.GetEdmModel());
}

处理不同的请求，例如:

GET http://localhost/MyApp/Costco/Foods

GET http://localhost/MyApp/Ikea/Foods

Answer 1

同一 EDM 模型中不能有 2 个具有相同名称的不同实体。您必须创建两个不同的 EDM 模型和路线，如下所示 -

var costcoBuilder = new ODataConventionModelBuilder();
costcoBuilder.EntitySet<Costco.Models.Food>("Foods");

var ikeaBuilder = new ODataConventionModelBuilder();
ikeaBuilder.EntitySet<Ikea.Models.Food>("Foods");

config.Routes.MapODataServiceRoute("CostcoRoute", "Costco", costcoBuilder.GetEdmModel());
config.Routes.MapODataServiceRoute("IkeaRoute", "Ikea", ikeaBuilder.GetEdmModel());
