ajax post call to mvc controller with antiforgery token and json object gives me error 500

Question

I am trying to send antiforgery token and json object via ajax call

here is my ajax call method

    $("button#submit-btn").on("click", function (e) {
       e.preventDefault();
       //var valid = $("form#sh-post-form").valid();

       var modell = { PlaceId: 1 };
       var token = $('input[name=__RequestVerificationToken]').val();

       $.ajax({
           contentType: 'application/json; charset=utf-8',
           dataType: "json",
           type: "POST",
           url: "/Post/SaveSharePost",
           data: { __RequestVerificationToken: token, model: JSON.stringify(modell) }
    });

and here is my controller

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult SaveSharePost(SharePostVM model, string retunrUrl = null)
    {
        if (!ModelState.IsValid)
            return View(model);
        return View(model);
    }

When I try to send the ajax call, it gives me internal error 500 and the error message says "The required anti-forgery form field __RequestVerificationToken is not present"

How can I fix it?

Thanks guys

data: { __RequestVerificationToken: token, PlaceId: 1 } and remove the contentType option (or else its data: JSON.stringify({ __RequestVerificationToken: token, PlaceId: 1 }), (you cannot mix the content types). But why are you not using $('form').serialize() to serialize all the inputs including the token? — user3559349

so basically I can't send object and antifogery token? How can i do with $('form').seriallize()?? — Michael

Of course you can (as per the first comment - the token just needs to be part of the object). And $('form').serialize(); serializes all your form controls within the form tag including the token. — user3559349

@StephenMuecke um as per your first comment, I need to send model object not "PlaceId: 1" the object will have more variables — Michael

I know! Just include __RequestVerificationToken: token as part of the object. But again, why not just use .serialize()? — user3559349

you should just addd forgery token to your model like:

model.__RequestVerificationToken=token

and

$.ajax({
       contentType: 'application/json; charset=utf-8',
       dataType: "json",
       type: "POST",
       url: "/Post/SaveSharePost",
       data: {model: JSON.stringify(modell) }
});
