如何在WebApi + Odata项目中更改路由

Question

I'm re-implementing WCF service and I choose to use WebAPI 2.2 + OData v4. Problem I'm facing is that I need to have route which contains '_' and I'm unable to implement it. Currently I have this:

public class AnnotationSharedWithController : ODataController
{
    ...
    [EnableQuery]
    public IQueryable<AnnotationSharedWith> Get()
    {
        return _unitOfWork.AnnotationSharedWith.Get();
    }
    ...
}

and my WebApiConfig.cs looks like this:

public static void Register(HttpConfiguration config)
{
    config.MapODataServiceRoute("webservice",null,GenerateEdmModel());
        config.Count();
}

private static IEdmModel GenerateEdmModel()
{
    var builder = new ODataConventionModelBuilder();
    builder.EntitySet<AnnotationSharedWith>("annotation_shared_with");
        return builder.GetEdmModel();
}

When I issue GET request I receive following error

{ "Message": "No HTTP resource was found that matches the request URI ' http://localhost:12854/annotation_shared_with '.", "MessageDetail": "No type was found that matches the controller named 'annotation_shared_with'." }

Answer 1

By default OData will search for annotation_shared_withController as defined in your EDM Model. Since your controller is named AnnotationSharedWithController it will return 404 .

Renamaing your controller class will solve the issue. But you will end up with messy class names.

You can implement your own Routing Conventions, see Routing Conventions in ASP.NET Web API 2 Odata for more details

Hope it helps.

Your could use routing attributes to achieve this:

1. Using ODataRouteAttribute class:

    public class AnnotationSharedWithController : ODataController { [EnableQuery] [ODataRouteAttribute("annotation_shared_with")] public IQueryable<AnnotationSharedWith> Get() { //your code } } 

2. Using ODataRoutePrefixAttribute and ODataRouteAttribute classes:

    [ODataRoutePrefixAttribute("annotation_shared_with")] public class AnnotationSharedWithController : ODataController { [EnableQuery] [ODataRouteAttribute("")] public IQueryable<AnnotationSharedWith> Get() { //your code } }
