Laravel 5.5 ajax call 419 (unknown status)

I do an ajax call but I keep getting this error:

419 (unknown status)

No idea what is causing this I saw on other posts it has to do something with csrf token but I have no form so I dont know how to fix this.

my call:

$('.company-selector li > a').click(function(e) {
     e.preventDefault();

     var companyId = $(this).data("company-id");


      $.ajax({
          headers: {
          'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
          },
          url: '/fetch-company/' + companyId,
          dataType : 'json',
          type: 'POST',
          data: {},
          contentType: false,
          processData: false,
          success:function(response) {
               console.log(response);
          }
     });
  });

My route:

Route::post('fetch-company/{companyId}', 'HomeController@fetchCompany');

My controller method

/**
 * Fetches a company
 *
 * @param $companyId
 *
 * @return array
 */
public function fetchCompany($companyId)
{
    $company = Company::where('id', $companyId)->first();

    return response()->json($company);
}

The ultimate goal is to display something from the response in a html element.

Use this in the head section: 

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

and get the csrf token in ajax:

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

Please refer Laravel Documentation csrf_token

If you are loading .js from a file you have to set a variable with the csrf_token in your "main" .blade.php file where you are importing the .js and use the variable in your ajax call.

index.blade.php

...
...
<script src="{{ asset('js/anotherfile.js') }}"></script>
<script type="text/javascript">
        var token = '{{ csrf_token() }}';
</script>

anotherfile.js

$.ajax({
    url: 'yourUrl',
    type: 'POST',
    data: {
        '_token': token
    },
    dataType: "json",
    beforeSend:function(){
        //do stuff
    },
    success: function(data) {
        //do stuff
    },
    error: function(data) {
        //do stuff
    },
    complete: function(){
        //do stuff
    }
});

some refs =>

...
<head>
    // CSRF for all ajax call
    <meta name="csrf-token" content="{{ csrf_token() }}" />
</head>
 ...
 ...
<script>
    // CSRF for all ajax call
    $.ajaxSetup({ headers: { 'X-CSRF-TOKEN': jQuery('meta[name="csrf-token"]').attr('content') } });
</script>

You have to get the csrf token..

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

After doing same issue is rise ,Just Add this meta tag< meta name="csrf-token" content="{{ csrf_token() }}" >

After this also the error arise ,you can check the Ajax error. Then Also check the Ajax error 

$.ajax({
    url: 'some_unknown_page.html',
    success: function (response) {
        $('#post').html(response.responseText);
    },
    error: function (jqXHR, exception) {
        var msg = '';
        if (jqXHR.status === 0) {
            msg = 'Not connect.\n Verify Network.';
        } else if (jqXHR.status == 404) {
            msg = 'Requested page not found. [404]';
        } else if (jqXHR.status == 500) {
            msg = 'Internal Server Error [500].';
        } else if (exception === 'parsererror') {
            msg = 'Requested JSON parse failed.';
        } else if (exception === 'timeout') {
            msg = 'Time out error.';
        } else if (exception === 'abort') {
            msg = 'Ajax request aborted.';
        } else {
            msg = 'Uncaught Error.\n' + jqXHR.responseText;
        }
        $('#post').html(msg);
    },
});

2019 Laravel Update, Never thought i will post this but for those developers like me using the browser fetch api on Laravel 5.8 and above. You have to pass your token via the headers parameter.

var _token = "{{ csrf_token }}";
fetch("{{url('add/new/comment')}}", {
                method: 'POST',
                headers: {
                    'X-CSRF-TOKEN': _token,
                    'Content-Type': 'application/json',
                },
                body: JSON.stringify(name, email, message, article_id)
            }).then(r => {
                return r.json();
            }).then(results => {}).catch(err => console.log(err));

This worked for me:

$.ajaxSetup({
  headers: {
    'X-CSRF-TOKEN': "{{ csrf_token() }}"
  }
});

After this set regular AJAX call. Example:

    $.ajax({
       type:'POST',
       url:'custom_url',

       data:{name: "some name", password: "pass", email: "test@test.com"},

       success:function(response){

          // Log response
          console.log(response);

       }

    });

I had SESSION_SECURE_COOKIE set to true so my dev environment didn't work when logging in, so I added SESSION_SECURE_COOKIE=false to my dev .env file and all works fine my mistake was changing the session.php file instead of adding the variable to the .env file.

just serialize the form data and get your problem solved.

data: $('#form_id').serialize(),
user_97038100 
formData = new FormData();
formData.append('_token', "{{csrf_token()}}");
formData.append('file', blobInfo.blob(), blobInfo.filename());
xhr.send(formData);

This error also happens if u forgot to include this, in your ajax submission request ( POST ), contentType: false, processData: false,

user_58062030

This works great for those cases you don't require a form.

use this in header:

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

and this in your JavaScript code:

$.ajaxSetup({
        headers: {
        'X-CSRF-TOKEN': '<?php echo csrf_token() ?>'
        }
    });

Got this error even though I had already been sending csrf token. Turned out there was no more space left on server.

A simple way to fixe a 419 unknown status on your console is to put this script inside in your FORM. {{ csrf_field() }}

user_79291790

in the name of the universe programmer

i send ajax with pure js and i understand when i dont set this method of ajax in pure js << xhr.setRequestHeader("Content-type", "application/x-www-form-urlencoded") >> i recive this error 419.

the full method of pure ajax is :

let token = document.querySelector('meta[name="csrf-token"]').content;

let xhr = new XMLHttpRequest();

// Open the connection
xhr.open("POST", "/seller/dashboard/get-restaurants");

// you have to set this line in the code (if you dont set you recive error 419):

xhr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
//* Set up a handler for when the task for the request is complete
xhr.onload = function () {
    
};

// Send the data.
xhr.send(`_token=${token}`);
