I am trying to post a JSON object to a ASP.NET MVC Controller but getting empty JSON

Question

Here is the Javascript code

$("#JSONPost").click(function (e) {
    var jsonData = { name: "ramesh", mobile: "9xxxxxxxxx" };
    $.post(
        "/Trace/JSONPostMethod",
        jsonData,
        function (data, status) {
            alert(status);
        });
    });
});

public ActionResult JSONPostMethod(object data)
{

}

data is coming as {} instead of the { name: "ramesh", mobile: "9xxxxxxxxx" }

Any idea how to get this JSON? I don't want to create a model class to get the data.

Found the solution. Inside the controller method do this,

var resolveRequest = HttpContext.Request;
resolveRequest.InputStream.Seek(0, SeekOrigin.Begin);
string jsonString = new StreamReader(resolveRequest.InputStream).ReadToEnd();

You can modify your Json code and write something which is not confusing as below:

$("#JSONPost").click(function (e) {
    var jsonData= {};
    jsonData.Name = "Ramesh";
    jsonData.Mobile = "9xxxxxxxxx";
    
    $.ajax(
        url: "/Trace/JSONPostMethod",
        data: JSON.stringify(jsonData),
        contentType: 'application/json',
        type: 'POST',
        success: function (data, status) {
            alert(status);
        });
    });
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

Correction in your Controller:

[HttpPost]
public JsonResult JSONPostMethod(object data)
{
   // your logic here
   return Json(data, JsonRequestBehavior.AllowGet);
}

Hope this helps.

No change in output,

Ramesh Viswanathan Over a year ago

[HttpPost] public ActionResult JSONPostMethod(object data) { string jsonstr = Newtonsoft.Json.JsonConvert.SerializeObject(data); }

jsonStr is coming as "{}"

IN the $.ajax method, I forgot to mention the success property. I have edited my answer. Have a look. Also, the return type of your Controller should be JsonResult

If you are passing Json into a controller, it should be of Json type. I have updated my answer I am sure you will get it in your controller variable.
