mvc json to object value missing

Question

I just converted json to c# class using json2csharp.com. Then trying to pass that json from view to my controller but problem is only "create_time" object value is garbing successfully no any other value is able to grab. Also please check my debug picture to get better idea. What mistake it can be?

Json i am passing from view:

{"id":"WH-0G571461Y8752214W-8RU19841BY148894W","create_time":"2017-02-27T23:14:14Z","resource_type":"invoices","event_type":"INVOICING.INVOICE.CREATED","summary":"An invoice has been created","resource":{"id":"INV2-3RK5-HZV6-35UP-3LLU","number":"8035","template_id":"TEMP-6MT19746YC041742U","status":"DRAFT","merchant_info":{"email":"[email protected]","first_name":"Dennis","last_name":"Doctor","business_name":"Medical Professionals, LLC","phone":{"country_code":"001","national_number":"5032141716"},"address":{"line1":"1234 Main St.","city":"Portland","state":"OR","postal_code":"97217","country_code":"US"}},"billing_info":[{"email":"[email protected]"}],"shipping_info":{"first_name":"Sally","last_name":"Patient","business_name":"Not applicable","phone":{"country_code":"001","national_number":"5039871234"},"address":{"line1":"1234 Broad St.","city":"Portland","state":"OR","postal_code":"97216","country_code":"US"}},"items":[{"name":"Sutures","quantity":100,"unit_price":{"currency":"USD","value":"5.00"}}],"invoice_date":"2017-02-27 PDT","payment_term":{"term_type":"NET_45","due_date":"2017-04-13 PDT"},"tax_calculated_after_discount":false,"tax_inclusive":false,"note":"Medical Invoice 27 Feb, 2017","total_amount":{"currency":"USD","value":"500.00"},"metadata":{"created_date":"2017-02-27 14:42:03 PDT"},"allow_tip":false,"links":[{"rel":"self","href":"https://api.paypal.com/v1/invoicing/invoices/INV2-3RK5-HZV6-35UP-3LLU","method":"GET"},{"rel":"send","href":"https://api.paypal.com/v1/invoicing/invoices/INV2-3RK5-HZV6-35UP-3LLU/send","method":"POST"},{"rel":"update","href":"https://api.paypal.com/v1/invoicing/invoices/INV2-3RK5-HZV6-35UP-3LLU/update","method":"PUT"},{"rel":"delete","href":"https://api.paypal.com/v1/invoicing/invoices/INV2-3RK5-HZV6-35UP-3LLU","method":"DELETE"}]},"links":[{"href":"https://api.paypal.com/v1/notifications/webhooks-events/WH-0G571461Y8752214W-8RU19841BY148894W","rel":"self","method":"GET","encType":"application/json"},{"href":"https://api.paypal.com/v1/notifications/webhooks-events/WH-0G571461Y8752214W-8RU19841BY148894W/resend","rel":"resend","method":"POST","encType":"application/json"}],"event_version":"1.0"}

You have shown what is being sent but not how it is being sent form the view. is it being submitted via form or ajax. — Nkosi

$.post(hookUrl, { testJson: testJson }) .done(function (data) { console.log(data); }); yes using jquery post method @Nkosi — Kevin himch

I'll assume you're on dotnet core (maybe on a migrated project?) because the code you're posting doesn't have any issues on previous versions of asp.net mvc.

If that's the case, it turns out that on dotnet core the model binding behaviour has changed a little compared to previous versions.

If you want the solution quickly just decorate the parameter of your POST action with [FromBody] attribute. It should work.

[HttpPost]
public ActionResult InvoicePaid([FromBody]RootObject rootObject)
{
    using (var ctx = new db_someEntities())
    {
    }
    return Json("ok");
}

The story is a little longer though, and very interesting by the way. If you want the details, I've not found any better resource than this post from Andrew Lock.

UPDATE I can confirm that if you add the [FromBody] on the action, (I've tested using a bare new asp.net core 2. web app project) it binds the model correctly.

Please let me know if you want me to provide the sources I've used so you can troubleshot from there.

Hope this helps!

No answer not works. The "create_time" object value only works

Karel Tamayo Over a year ago

@Kevinhimch, are you using dotnet core?

Kevin himch Over a year ago

Yes sure. using System.Web.Http; also [System.Web.Http.HttpPost] used but still not works!

Karel Tamayo Over a year ago

Weird then because I tested the code before answering and after putting the [FromBody] I was able to receive the model successfully.

@Kevinhimch, please see the update! If you need more help just let me know.

Most probably the data being sent it not formatted properly

From comments it was indicated that the data was being sent like

$.post(hookUrl, { testJson: testJson }).done(function (data) { console.log(data); });

consider formatting the data and including the content type

var data = JSON.stringify(testJson);  //replace content with your JSObject
$.post(hookUrl, data, null, "application/json")
 .done(function (data) { console.log(data); });

Or using the longer syntax

var data = JSON.stringify(testJson); //replace content with your JSObject
$.ajax({
  type: "POST",
  url: hookUrl,
  data: data,
  dataType: "application/json",
  success: function (data) { console.log(data); }
});

@Kevinhimch the create_time is the default value, so it is also not working. can you show the raw request being sent to the server. the url is correct, how and what data you send is the problem.

You need to use [FromBody], so MVC knows where to look for the data.

[HttpPost]
public ActionResult InvoicePaid([FromBody]RootObject rootObject)
