I did a very simple test on ASP.NET MVC4 WebAPI and found some interesting issue:
When a method is taking complex type, it will work, but when it takes string or int, it will throw 404, as the screen shot given: The "AddProduct" works, but "Test" and "Test1" is always not found.
How should I invoke the method correctly?

A simple solution is to check for the HTTP status code 404 in the response. If found, you can redirect the control to a page that exists. The following code snippet illustrates how you can write the necessary code in the Configure method of the Startup class to redirect to the home page if a 404 error has occurred.
A Get does not send the body of the form, it only requests a URL. Use a <form> in your view and post it to your controller method, which needs to be decorated with HttpPost.
IHttpActionResult contains a single method, ExecuteAsync, which asynchronously creates an HttpResponseMessage instance. C# Copy. public interface IHttpActionResult { Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken); }
You need to decorate your string or int parameter with the [FromBody] attribute.
[HttpPost] public string Test([FromBody]string username)
[HttpPost] public int Test1([FromBody]int value)
