如何告诉MVC 4视图返回带有子路由的JSON结果

Question

What I want is a solution for the next problem: 1. I have an MVC 4 view + controller that renders Index and another for Details 2. to access that information I go to http://localhost:1234/Movies and to http://localhost:1234/Movies/1 (for details) 3. I want to create a new route http://localhost:1234/json/Movies and http://localhost:1234/json/Movies/1 4. in the Method of Index I want the code to be like:

public ActionResult Index(string format)
        {
            return View(db.Movies.ToList());
        }

or

public ActionResult Index(string format)
        {
            return ChooseView(db.Movies.ToList());
        }

and I want the view to render the corrent (html\\json) according to the route.

Is that possible?

Thanks.

Answer 1

In your controller

public class MoviesController : Controller
{
    [AcceptVerbs(HttpVerbs.Get)]
    public ActionResult Index(string format)
    {
        return ToResult(db.Movies.ToList(), format);
    }
}

This will make /Movies get the HTML page rendered by the view Index.cshtml and /Movies?format=json get the list of movies as JSON data.

Helper method

public static ActionResult ToResult(object data, string format)
{
    if (format == "json")
    {
        return Json(data, JsonRequestBehavior.AllowGet);
    }
    else
    {
        return View(data);
    }
}

Answer 2

use return Json(data)
