我从
获得了一些路由约定的示例在此示例中，我可以使用此查询/odata/Products(1)/Suppliers
我想在“产品”中添加两个参数。例如/odata/Products(1,2)/Suppliers
我该如何设置？
这是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);
}
}
