API

ASP.NET-Core

in my controller:

 public class ShoppingCartController : Controller
    {
         
        // GET: /ShoppingCart/
        public ActionResult Index()
        {            
            return View(this.HttpContext);
        }
...
}

in view:i try to send the httpcontext to api method as following.

var urll = 'https://localhost:44379/api/apiClass/IndexOfCarts';
$.ajax({
            type: "post",
            url: urll, error: function () { alert("error carts") },
               @*data: JSON.stringify(@Model.HttpContext, null, '\t'),*@
         data: { httpContext:  @Model},
        //    contentType: 'application/json',
        //dataType:"json",
            success: function (dataa) {
                alert("****ok carts****")

            }
        });

in api action:

[Microsoft.AspNetCore.Mvc.HttpPost()]
      public ActionResult<string> IndexOfCarts([FromForm]HttpContext httpContext)
      {


          return "ddd";
      }

the api action dont call.but when change the parameter to another types and use ajax to request to api action, the api action called and work

What I have tried:

i change[fromform] to [frombody] for parameter,but also the api not called.(The program does not go to the api action)
