Ajax post from jquery results in null at Controller #6438 | Support Center

aggarwal created 5 years ago

Hi i am following this guidance.

https://aspnetboilerplate.com/Pages/Documents/Javascript-API/AJAX

Problem: null is received in the controller method. It is hitting the right controller method.

Jquery code

                                action: function (data) {
                                    var record = { id: data.record.integration.id };
                                    abp.ajax({
                                        url: '/App/Integrations/Register',
                                        data: JSON.stringify(record),
                                    }).done(function (data) {
                                        abp.message.confirm(
                                            'You will be redirected',
                                            'Are you sure?',
                                            function (isConfirmed) {
                                                if (isConfirmed) {
                                                    window.location = data.url
                                                }
                                            }
                                        )
                                    });
                                }

Model

    public class IdModel
    {
        int id { get; set; }
    }

Controller method

        [HttpPost]
        public JsonResult Register(IdModel id)
        {
            string compCode = id.ToString();
            string url = "";

            if (!string.IsNullOrEmpty(compCode))
            {
                var t = new HmrcOauth()
                {
                    State = compCode
                };

                url = t.GetAuthorizationUrl();
            }

            object json = new { Url = url };
            return Json(json);

        }

Please advice. I have already spent 2 days trying different techniques.

Thanks in advance.

Try marking id as public.

public class IdModel { public int id { get; set; } }

Hi @aaron,

I made that change. The object is still coming as null.

Just renames id to xid to avoid any another conflict. screenshot from console is below.

Its value is coming as 0 now in controller.

Try renaming id in controller.

aggarwal created 5 years ago

Renamed everything(controller and scripts) to as below but value for Xid is coming as 0.

        public JsonResult GBVATRegister(IdModel IdModel)
        {
            string compCode = IdModel.Xid.ToString();
            string url = "";

@aaron

This is the only issue preventing me to close down this functionality. Please help.

I also tried adding another string parameter. It is coming as null.

Hence there seems to be an issue receiving the json object.

TL;DR: Add the [FromBody] attribute to the parameter in your ASP<span></span>.NET Core controller action

— https://andrewlock.net/model-binding-json-posts-in-asp-net-core/

- public JsonResult Register(IdModel model) + public JsonResult Register([FromBody] IdModel model)

Existing examples in ASP<span></span>.NET Zero: AccountController's Impersonate and SwitchToLinkedAccount methods.

It worked :)

I would buy your a beer right now, if you were here.

Thank you.
