Trying to get JSON from MVC Controller and getting error net::ERR_INCOMPLETE_CHUNKED_ENCODING

问题

I am trying to get JSON from my controller to use in jQuery. I have the following code. When I visit the URL in my browser it returns the json so I know that the controller is working... But I get the following

GET http://localhost:52802/Checkout/GetContactById?id=1 net::ERR_INCOMPLETE_CHUNKED_ENCODING

client-side jQuery

var theUrl = window.location.origin + '/Checkout/GetContactById?id=' + contactId;

$.ajax({
    url: theUrl,
    type: "GET",
    success: function (result) {
        alert("Success");
    },
    error: function (error) {
        alert("Error");
    }
});

Server-side Controller

[HttpGet]
public IActionResult GetContactById(int id)
{
  Contact contact = this.checkoutDataAccess.GetContactById(id);
  return Json(contact);
}

The only alert I get is "Error"

Update

After more research it looks like everything is loading... but I am getting an error

Failed to load response data

in the console.

I stepped through the code and everything works on the controller side. I am not sure if it is not formatting the JSON correct, or if I am not receiving it correctly. Either way I have no idea what is going on.

回答1:

Actually you are getting the text Error since you put alert("Error"); Try alert(error); instead Or try debugging using firebug

回答2:

Try adding datatype JSON to the ajax call.

And maybe try adding the parameter in the body.

like so:

var theUrl = window.location.origin + '/Checkout/GetContactById';

$.ajax({
   url: theUrl,
   type: "GET",
   dataType: "json",
   data: { id: contactId },
   success: function (result) {
      alert("Success");
   },
   error: function (error) {
      alert("Error");
   }
});

And i would suggest using Url.Action helper.

like:

 $.ajax({
       url: '@Url.Action("GetContactById", "Checkout")',
       type: "GET",
       dataType: "json",
       data: { id: contactId },
       success: function (result) {
         alert("Success");
       },
       error: function (error) {
          alert("Error");
       }
    });

I had same problem and after looking for several possible solutions, I've tried to consume my api form Postman and discovered that I was returning a bad formed JSON. In my case was because one of properties of my ViewModel was int[] type. After remove this property I could retrieve data normally.

I hope it helps.
