Laravel Tokenmismatchexception in Ajax Request

Laravel csrf token mismatch for ajax POST Request

You have to add data in your ajax request. I hope so it will be work.

data: {
        "_token": "{{ csrf_token() }}",
        "id": id
        }

Handle TokenMismatchException for ajax request

Laravel token miss match exception code is 419, you can use directly 419 instead of $exception->getStatusCode()

TokenMismatchException in VerifyCsrfToken.php line 67 on laravel using ajax

You should add csrf_field to your main blade :

{{ csrf_field() }}

Then add _token to your request :

var _token = $('input[name="_token"]').val();

function eliminar(id){
  $.ajax({
    type: "DELETE",
    url: "task/"+id,
    data: { _token : _token },
    success: function (data) {
      console.log(data);
    },
    error: function (data) {
      alert('Error:', data);
    }
  });
}

Or you could add it one time in ajaxSetup and it will affect all calls to $.ajax or Ajax-based derivatives such as $.get() :

$.ajaxSetup(
{
    headers:
    {
        'X-CSRF-Token': $('input[name="_token"]').val()
    }
});

Take a look to CSRF Protection.

Hope this helps.

How to to handle token mismatch exception in laravel post ajax?

In your app/Exceptions/Handler.php file

Add a handler for TokenMismatchException in the render method

public function render($request, Exception $exception)
{
    if ($exception instanceof \Illuminate\Session\TokenMismatchException) {
        if ($request->expectsJson()) {
            return response()->json([
                'error' => 'Token mismatch'
            ], $exception->getStatusCode());
        };
    }

    return parent::render($request, $exception);
}

This will return an error json response. You can customize the error response to suit your needs.

Ajax Post to Laravel - CSRF Token Mismatch

I had the same problem
try to put include CSRF tag in your meta like so

<meta name="csrf-token" content="{{ csrf_token() }}" />

and read it in your ajax code like so :

<script type="text/javascript">
$.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    }
});
</script>

Last Update

Please modify your url variable like so :

jQuery.ajax({
    type: "POST",
    url: '/my-route'+'?_token=' + '{{ csrf_token() }}',
    data: data,
    success: function() {
         console.log("A");
    }
  });
