HTTP POST request body not binding in ASP .NET MVC-CodePudding

I am a starter with ASP.NET MVC. I generated a basic class:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using MyPluginProject.Models;

namespace MyPluginProject.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            return View();
        }
        
        public ActionResult About()
        {
            ViewBag.Message = "Your application description page.";

            return View();
        }

        public ActionResult Contact()
        {
            ViewBag.Message = "Your contact page.";
            return View();
        }
        
        [HttpPost]
        public JsonResult data(TestRequestObject testRequestObject)
        {
            TestResponseObject respobj = new TestResponseObject();
            
            respobj.id = testRequestObject.Id;
            respobj.name = testRequestObject.Name;
            
            //return Newtonsoft.Json.JsonConvert.SerializeObject(respobj);
            return Json(respobj);
        }
    }
}

and the TestRequestObject POCO looks like this:

 public class TestRequestObject
 {
     public string Id { get; set; }
     public string Name { get; set; }
     public string Address { get; set; }
 }

The route config:

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

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

However when I run this locally and send request from Postman with

curl --location --request POST 'http://localhost:50132/home/data' \
--header 'Content-Type: application/json' \
--data-raw '{   
"id": "123456789",
"name": "John Smith",
"address":"ftyrhrrhrhhr"
}'

the value is not getting bound to the TestRequestObject. I tried [FromBody], however it's only allowed for .NET Core it seems. I don't seem to understand as to what is going wrong here.

CodePudding user response：

Try sending POST request this way.

curl -d '{json}' -H 'Content-Type: application/json' https://example.com/login

CodePudding user response：

firstly you should use [Route("api/[controller]/[action]")] Tag in upon of your controller class in order to rout URL to this block of your code

    [Route("api/[controller]/[action]")]
    public class HomeController : Controller
    { 
     ...

secondly you are starter in asp , i suggest you that you use Swagger to generate better ui and help you to send HTTTP request in correct format to Webapplication , for adding swagger to your project follow below :
