I have written code for sending

            $http({
                url: remoteService + '/SaveDraft',
                method: 'POST',
                data: $.param({ jsonData: strObj }),
                headers: { 'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8' },
                //params: { jsonData: strObj },                    
                //timeout: d,
                //cache: d,
                //transformRequest: d,
                //transformResponse: d
            }).then(function (results) {
                return results;
            }).catch(function (e) {
                throw e;
            });

and Here is my api controller method

    [HttpPost]
    public int SaveDraft(string jsonData)
    {
        try
        {
            return 1;
        }
        catch (Exception)
        {
            throw;
        }
    }

What is problem of my code. please help me. Thanks

If you want to pass a large string that for cause you have to use two method one is javascript and another is api method.

The java script method look like this

               var data = {                    
                Data: strObj
            };

           $http({
                url: url,
                method: 'POST',
                data: data,
                headers: { 'Content-Type': 'application/json; charset=UTF-8' },
                //params: { jsonData: "I am shohel rana" },
                //timeout: 10,
                //cache: false,
                //transformRequest: false,
                //transformResponse: false
            }).then(function (success) {
                return success;
            }).catch(function (e) {
                throw e;
            });

and the api method is

    [HttpPost]
    public bool SaveDraft([FromBody]object draft)
    {
        try
        {

        }
        catch (Exception)
        {
            throw;
        }
    }
