Routing with multiple Get methods in ASP.NET Web API

Question

I am using Web Api with ASP.NET MVC, and I am very new to it. I have gone through some demo on asp.net website and I am trying to do the following.

I have 4 get methods, with the following signatures

public List<Customer> Get()
{
    // gets all customer
}

public List<Customer> GetCustomerByCurrentMonth()
{
    // gets some customer on some logic
}

public Customer GetCustomerById(string id)
{
    // gets a single customer using id
}

public Customer GetCustomerByUsername(string username)
{
    // gets a single customer using username
}

For all the methods above I would like to have my web api somewhat like as shown below

• List Get() = api/customers/
• Customer GetCustomerById(string Id) = api/customers/13
• List GetCustomerByCurrentMonth() = /customers/currentMonth
• Customer GetCustomerByUsername(string username) = /customers/customerByUsername/yasser

I tried making changes to routing, but as I am new to it, could'nt understand much.

So, please can some one help me understand and guide me on how this should be done. Thanks

From here Routing in Asp.net Mvc 4 and Web Api

Darin Dimitrov has posted a very good answer which is working for me.

It says...

You could have a couple of routes:

public static class WebApiConfig
{
    public static void Register(HttpConfiguration config)
    {
        config.Routes.MapHttpRoute(
            name: "ApiById",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional },
            constraints: new { id = @"^[0-9]+$" }
        );

        config.Routes.MapHttpRoute(
            name: "ApiByName",
            routeTemplate: "api/{controller}/{action}/{name}",
            defaults: null,
            constraints: new { name = @"^[a-z]+$" }
        );

        config.Routes.MapHttpRoute(
            name: "ApiByAction",
            routeTemplate: "api/{controller}/{action}",
            defaults: new { action = "Get" }
        );
    }
}
