Question

I am trying to redirect from controller action to another controller action like below:

public class LoginController : Controller
{

    public ActionResult Index()
    {
        return View();
    }

    public ActionResult RedirectToRegister()
    {
        return RedirectToAction("Index", "Register");
    }

}

public class RegisterController : Controller
{

    public ActionResult Index()
    {
        return View();
    }

}

I have Url in my cshtml page like below:

<script type="text/javascript">
    var LoginRedirectToRegisterUrl = '@Url.Action("RedirectToRegister", "Login")';
</script>

and I am calling from js like below:

function CallRedirectToRegister() {
    window.location = LoginRedirectToRegisterUrl;
}

But it is not redirecting me to Register Page. My routing is like below:

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

    routes.MapRoute(
        name: "Default",
        url: "{controller}/{action}/{id}",
        defaults: new { controller = "Login", action = "Index", id = UrlParameter.Optional }
    );
}

Where am I doing wrong?

Answer 1

The server-side redirection looks fine, but your client-side call not so much: $.post(LoginRedirectToRegisterUrl); starts an AJAX call to the URL. It does not change the current page. For that use this:

function CallRedirectToRegister() {
    window.location = LoginRedirectToRegisterUrl;
}

This will issue an HTTP GET request. You need to remove the [HttpPost] attribute from your action for this to work. If you can't do that you have to put a HTML form on your page and submit that to get a POST request. Something like this:

function CallRedirectToRegister() {
    $('<form id="redirectForm">').attr('method', 'post').attr('action', LoginRedirectToRegisterUrl).appendTo($('body')).submit();
}

Ajax调用不会重定向到页面。而不是ajax调用，使用

window.location = LoginRedirectToRegisterUrl;

并且无法重定向到POST方法，因为HTTP不支持使用POST重定向到页面。
