jquery - How to make ajax request with anti-forgery token in mvc

Question

I have problem with below details from MVC project.

When I am trying to use jquery ajax request with loading panel like spinning gif (or even text), I am getting error, observed from fiddler that

The required anti-forgery form field "__RequestVerificationToken" is not present.

If I comment [ValidateAntiForgeryToken] attribute at POST action method and use loading panel it is working fine.I want to know why I am getting this error.

I have even used the query string serialized with

__RequestVerificationToken= $('input[name="__RequestVerificationToken"').val()

still I am getting error

The anti-forgery token could not be decrypted. If this application is hosted by a Web Farm or cluster, ensure that all machines are running the same version of ASP.NET Web Pages and that the <machineKey> configuration specifies explicit encryption and validation keys.

AutoGenerate cannot be used in a cluster

What should I use?

Here it updated question code

var token = $('input[name="__RequestVerificationToken"]').val();
$('#submitaddress').click(function subaddr(event) {
    event.preventDefault();
    event.stopPropagation();
  //$('#addAddress').html('<img src="/img/animated-overlay.gif"> Sending...');
   // $('#addAddress').blur();
    //  $(this).bl
    if ($('#Jobid').val()!="") {
        $('#TransportJobId').val(parseInt($('#Jobid').val()));
        $.ajax(
              {
                  url: '/TransportJobAddress/create',
                  type: 'POST',
                  data: "__RequestVerificationToken=" + token + "" + $('form[action="/TransportJobAddress/Create"]').serialize(),
                  success: function poste(data, textStatus, jqXHR) { $('#addAddress').html(data); return false; },
                  error: function err(jqXHR, textStatus, errorThrown) { alert('error at address :' + errorThrown); }
              });
    }
    else {
        var transportid = 2;
        $.ajax({
            url: '/TransportJob/create',
            type: 'POST',
            data: "__RequestVerificationToken=" + token + "" + $('form[action="/TransportJob/Create"]').serialize(),
            success: function sfn(data, textStatus, jqXHR) {
                transportid = parseInt(data);
                $('#Jobid').val(data);
               // alert('inserted id :' + data);
                $('#TransportJobId').val((transportid));
                $.ajax(
         {

             url: '/TransportJobAddress/create',
             type: 'POST',
             //beforeSend: function myintserver(xhr){  
             //        $('#addAddress').html('<div id="temp_load" style="text-align:center">please wait ...</div>');
             //}, 
             data: "__RequestVerificationToken=" + token + "" + $('form[action="/TransportJobAddress/Create"]').serialize(),
             success: function poste(data, textStatus, jqXHR) {
                 $('#addAddress').html(data);

             },
             error: function err(jqXHR, textStatus, errorThrown) {
                 alert('error at address :' + errorThrown);
             }

         });
            },
            error: function myfunction(jqXHR, textStatus, errorThrown) {
                alert("error at transport :" + jqXHR.textStatus);
            },
            complete: function completefunc() {
              //  alert('ajax completed all requests');
                return false;
            }

        });
    }
});

form tags

<form action="/TransportJob/Create" method="post"><input     name="__RequestVerificationToken" type="hidden"   value="ydYSei0_RfyBf619dQrhDwwoCM7OwWkJQQEMNvNdAkefiFfYvRQ0MJYYu0zkktNxlJk_y1ZJO9-yb-  COap8mqd0cvh8cDYYik4HJ0pZXTgE1" />   

TransportJob form tag 2 on same page

<form action="/TransportJobAddress/Create" method="post" novalidate="novalidate"><input name="__RequestVerificationToken" type="hidden"    value="Np2vUZJPk1TJlv846oPSU6hg4SjMHRcCk1CacaqZbpHOg8WbV4GZv06noRDl7F_iT9qQf3BIXo3n9wGW68sU mki7g3-ku_BSHBDN-g2aaKc1"> 

Answer 1

Rather than manually adding it to each request, I usually do something like this:

var token = $('input[name="__RequestVerificationToken"]').val();
$.ajaxPrefilter(function (options, originalOptions) {
  if (options.type.toUpperCase() == "POST") {
    options.data = $.param($.extend(originalOptions.data, { __RequestVerificationToken: token }));
  }
});

This will automatically add your token to any ajax POST you do.
