Question

I created a simple mvc3 site with a home controller with these actions.

public JsonResult Param(string id)
        {
            string upper = String.Concat(id, "ff");
            return Json(upper);
        }
        public ContentResult Param2(string id)
        {
            string upper = String.Concat(id, "ff");
            return Content( upper);
        }
        public JsonResult Param3(string id)
        {
            string upper = String.Concat(id, "ff");
            io gg = new io();
            gg.IOName = upper;
            return Json(gg);
        }
    }
    public class io
    {
         public string IOName {get;set;}
    }

I am using Delphi XE and the IPworks that came with it.
Problem #1. No matter what I do I cannot send the post data. I set a breakpoint on the functions. So id is always null.

So these work (for posting data only) for any url.

 Json1.Get('http://localhost:1257/home/Param?id=ss');
REST1.Get('http://localhost:1257/home/Param2?id=kk');

But these DO NOT work (for posting data only) for any url.

REST1.PostData :='id=110559%2C102%2C0%2C0';
REST1.POST('http://localhost:1257/home/Param2');

or

json1.PostData:='id=110';
Json1.post('http://localhost:1257/home/Param');

but this works for posting

Webform.AddFormVar('id', '110559%2C102%2C0%2C0');
  Webform.SubmitTo('http://localhost:1257/home/Param2');

SO How am I formatting my parameters wrong????
Also I Never get the variable gg formatted in a JSON way. Either blank or an error

Answer 1

GET requests are disabled by default for actions returning JSON. You can enable them like this:

return Json(upper, JsonRequestBehavior.AllowGet);
