不同控制器中的OData自定义路由约定

Question

我从得到了一些路由约定的例子

https://learn.microsoft.com/en-us/aspnet/web-api/overview/odata-support-in-aspnet-web-api/odata-routing-conventions.

在本例中，我可以使用以下查询/odata/Products(1)/Suppliers获取实体的属性

我想在产品中加入两个参数。例如/odata/Products(1,2)/Suppliers如何设置？

这里是CustomRoutingConvention类：

public class NavigationIndexRoutingConvention : EntitySetRoutingConvention
{
public override string SelectAction(ODataPath odataPath, HttpControllerContext context, 
ILookup<string, HttpActionDescriptor> actionMap)
{
if (context.Request.Method == HttpMethod.Get && 
odataPath.PathTemplate == "~/entityset/key/navigation/key")
{
NavigationPathSegment navigationSegment = odataPath.Segments[2] as NavigationPathSegment;
IEdmNavigationProperty navigationProperty = navigationSegment.NavigationProperty.Partner;
IEdmEntityType declaringType = navigationProperty.DeclaringType as IEdmEntityType;
string actionName = "Get" + declaringType.Name;
if (actionMap.Contains(actionName))
{
// Add keys to route data, so they will bind to action parameters.
KeyValuePathSegment keyValueSegment = odataPath.Segments[1] as KeyValuePathSegment;
context.RouteData.Values[ODataRouteConstants.Key] = keyValueSegment.Value;
KeyValuePathSegment relatedKeySegment = odataPath.Segments[3] as KeyValuePathSegment;
context.RouteData.Values[ODataRouteConstants.RelatedKey] = relatedKeySegment.Value;
return actionName;
}
}
// Not a match.
return null;
}
}

Web api配置类：

public static class WebApiConfig
{
public static void Register(HttpConfiguration config)
{
ODataModelBuilder modelBuilder = new ODataConventionModelBuilder();
// Create EDM (not shown).
// Create the default collection of built-in conventions.
var conventions = ODataRoutingConventions.CreateDefault();
// Insert the custom convention at the start of the collection.
conventions.Insert(0, new NavigationIndexRoutingConvention());
config.Routes.MapODataRoute(routeName: "ODataRoute",
routePrefix: "odata",
model: modelBuilder.GetEdmModel(),
pathHandler: new DefaultODataPathHandler(),
routingConventions: conventions);
}
}

OData不允许您这样做。您可以为此创建函数：OData Actions and Functions
