I am trying to send a JSON to the server by encoding it into the URI using Jquery.param but I get the following error.

window.location.href = BriefExportPath+$.param(JSON.stringify({
                        title: $('.ui-dialog-title').text(),
                        items: ko.utils.arrayMap(Neptune.BriefCountrySection.SelectedCountries(), function (item) {
                            return item.ItemName
                        })
                    }))

        public FileContentResult ExportCsv(string json)
        {
            var x = new System.Web.Script.Serialization.JavaScriptSerializer();
            object obj = x.DeserializeObject(json);
            //return File(Helpers.BriefCsvBytes.GetCsvBytes(items), "text/csv", title); 
            return null;
        }

• are you using - JSON.stringify(data) - before adding it to the querystring? – David Commented Mar 6, 2013 at 14:29
• have you tried using HttpUtility.UrlDecode() – Dave Hogan Commented Mar 6, 2013 at 14:32
• The important line is surely before 579. Where does the json variable get assigned? – Joe Commented Mar 6, 2013 at 14:32
• It looks like you the querystring parameter name is wrong. From that screenshot it looks like its is '0' – David Commented Mar 6, 2013 at 14:33

From the manual for jQuery.param():

Create a serialized representation of an array or object, suitable for use in a URL query string or Ajax request.

You are passing it the return value of JSON.stringify which is a string.

You need to pass it an object instead.:

var json = JSON.stringify(etc etc);
var url = BriefExportPath + $.param( { "json": json } );
location = url;

Your server side code will then need to extract the data from the json query key.

Why you are not using this

$.ajax({
    url: url,
    type: "POST",
    data: JSON.stringify(data),
    contentType: "application/json",
    plete: callback
});

instead of querystring.

Your server expects the input to end up in a predictable variable name somewhere, yet you seem to try and put it in a GET variable named 0, as we can see in ExportCsv?0=

What your code expects is ExportCsv?json=

Make sure that you are passing the value to the correct GET variable name

var jObj = (JObject)JsonConvert.DeserializeObject(json);
