How to include the CSRF token in the headers in Dropzone upload request?

I am working on a single page application and I am using Laravel 5 for the web service.

All forms are submitted asynchronously and I use a beforeSend on them to attach the CSRF token which I take from the meta tag like so:

$.ajax({
url: '/whatever/route',
type: 'POST',
dataType: 'JSON',
data: $('form#whatever-form').serialize(),
beforeSend: function(request) {
return request.setRequestHeader('X-CSRF-Token', $("meta[name='token']").attr('content'));
},
success: function(response){
rivets.bind($('#whateverTag'), {whateverData: response});
},
error: function(response){
}
});


All my forms work fine but dropzone upload doesn't. It gives me back a
TokenMismatchException
exception. Here is my dropzone code to update the profile photo:

$("#mydropzone").dropzone({
url: "/profile/update-photo",
addRemoveLinks : true,
maxFilesize: 5,
dictDefaultMessage: '<span class="text-center"><span class="font-lg visible-xs-block visible-sm-block visible-lg-block"><span class="font-lg"><i class="fa fa-caret-right text-danger"></i> Drop files <span class="font-xs">to upload</span></span><span>&nbsp&nbsp<h4 class="display-inline"> (Or Click)</h4></span>',
dictResponseError: 'Error uploading file!'
});


I have tried putting the
beforeSend
in here too:

$("#mydropzone").dropzone({
url: "/profile/update-photo",
addRemoveLinks : true,
maxFilesize: 5,
dictDefaultMessage: '<span class="text-center"><span class="font-lg visible-xs-block visible-sm-block visible-lg-block"><span class="font-lg"><i class="fa fa-caret-right text-danger"></i> Drop files <span class="font-xs">to upload</span></span><span>&nbsp&nbsp<h4 class="display-inline"> (Or Click)</h4></span>',
dictResponseError: 'Error uploading file!',
beforeSend: function(request) {
return request.setRequestHeader('X-CSRF-Token', $("meta[name='token']").attr('content'));
},
});


I have also tried to put a global ajaxSetup in my main file like so:

$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="token"]').attr('content')
}
});


It is still not working. What am I doing wrong? How can I pass the CSRF token in the header with the dropzone upload so as to not a get an exception?

Answer

Okay so this code is working just fine now:

$("#mydropzone").dropzone({
    url: "/profile/update-photo",
    addRemoveLinks : true,
    maxFilesize: 5,
    dictDefaultMessage: '<span class="text-center"><span class="font-lg visible-xs-block visible-sm-block visible-lg-block"><span class="font-lg"><i class="fa fa-caret-right text-danger"></i> Drop files <span class="font-xs">to upload</span></span><span>&nbsp&nbsp<h4 class="display-inline"> (Or Click)</h4></span>',
    dictResponseError: 'Error uploading file!',
    headers: {
        'X-CSRF-Token': $('meta[name="token"]').attr('content')
    }
});

So basically I needed to add the X-CSRF-Token in the header of the Dropzone request. Works like charm now.
