C＃MVC获取表单数据作为URL参数

Question

I have a controller that is accepting 3 values from a submitted form, this works fine.

What I need to do now, however is enable a generated link to post the same data to the controller.

The controller looks like this:

[HttpPost]
        public ActionResult Customer(string lastName, string postCode, string quoteRef)
        {

         // Using passed parameters here

        }

I am aware routing allows prettier URL's but in this case I need the form to be able to accept the three values either through the submitted form or by the following hyperlink format:

path.to.url/Home/Customer?lastName={1}&postcode={2}&quoteRef={3}

I have looked into routing but I can't find anything that will allow me to achieve this outcome.

My routes are currently set up as the following:

routes.MapRoute(
                "Customer",
                "{controller}/{action}/{id}/{lastName}/{postCode}/{quoteRef}", 
                new {controller = "Home", action = "Customer", id = ""}
                );

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

Answer 1

Just set the form action method to use GET instead of POST to send the parameters as query string

@using (Html.BeginForm("Customer", "Controller", FormMethod.Get

Decorate action method with HttpGet

[HttpGet]
public ActionResult Customer(string lastName, string postCode, string quoteRef)
{
}

Answer 2

path.to.url/Home/Customer?lastName={1}&postcode={2}&quoteRef={3}

this would work only for [HttpGet] attribute, not [HttpPost]

So your method should look like:

[HttpGet]
public ActionResult Customer(string lastName, string postCode, string quoteRef)
{

// Using passed parameters here

}

And if you still want to use [HttpPost] , you should make a little diffrence between GET and POST method, like here - you cannot have these methods with identical parameters.

URL: path.to.url/Home/Customer?lastName={1}&postcode={2}&quoteRef={3}&method={4}

[HttpGet]
public ActionResult Customer(string lastName, string postCode, string quoteRef, string method)
    { .. }
