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}', '[email protected]');

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.

Solution 1

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

Solution 2

Another way to resolve this is to use the _token field in ajax data and set the value of {{csrf_token()}} in blade. Here is a working code that I just tried at my end.

$.ajax({
    type: "POST",
    url: '/your_url',
    data: { somefield: "Some field value", _token: '{{csrf_token()}}' },
    success: function (data) {
       console.log(data);
    },
    error: function (data, textStatus, errorThrown) {
        console.log(data);

    },
});

It's possible your session domain does not match your app URL and/or the host being used to access the application.

1.) Check your .env file:

SESSION_DOMAIN=example.com
APP_URL=example.com

2.) Check config/session.php

Verify values to make sure they are correct.

Solution 4

This is similar to Kannan's answer. However, this fixes an issue where the token should not be sent to cross-domain sites. This will only set the header if it is a local request.

HTML:

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

JS:

$.ajaxSetup({
    beforeSend: function(xhr, type) {
        if (!type.crossDomain) {
            xhr.setRequestHeader('X-CSRF-Token', $('meta[name="csrf-token"]').attr('content'));
        }
    },
});

Solution 5

use this in your page

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

and in your ajax used it in data:

_token: '{!! csrf_token() !!}',

that is:

$.ajax({
          url: '/fetch-company/' + companyId,
          dataType : 'json',
          type: 'POST',
          data: {
                   _token: '{!! csrf_token() !!}',
                 },
          contentType: false,
          processData: false,
          success:function(response) {
               console.log(response);
          }
     });

Thanks.

If you already done the above suggestions and still having the issue.

Make sure that the env variable:

SESSION_SECURE_COOKIE

Is set to false if you don't have a SSL certificate, like on local.

Solution 7

in my case i forgot to add csrf_token input to the submitted form. so i did this HTML:

<form class="form-material" id="myform">
...
<input type="file" name="l_img" id="l_img">
<input type="hidden" id="_token" value="{{ csrf_token() }}">
..
</form>

JS:

//setting containers
        var _token = $('input#_token').val();
        var l_img = $('input#l_img').val();
        var formData = new FormData();
        formData.append("_token", _token);
        formData.append("l_img", $('#l_img')[0].files[0]);

        if(!l_img) {
            //do error if no image uploaded
            return false;
        }
        else
        {
            $.ajax({
                type: "POST",
                url: "/my_url",
                contentType: false,
                processData: false,
                dataType: "json",
                data : formData,
                beforeSend: function()
                {
                    //do before send
                },
                success: function(data)
                {
                    //do success
                },
                error: function(jqXhr, textStatus, errorThrown) //jqXHR, textStatus, errorThrown
                {
                    if( jqXhr.status === "422" ) {
                        //do error
                    } else {
                        //do error
                    }
                }
            });
        }
        return false; //not to post the form physically

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
    }
});

Solution 9

Even though you have a csrf_token, if you are authenticate your controller actions using Laravel Policies you can have 419 response as well. In that case you should add necessary policy functions in your Policy class.

Solution 10

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>
...

Solution 11

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);
    },
});

Solution 12

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));

Solution 13

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: "[email protected]"},

       success:function(response){

          // Log response
          console.log(response);

       }

    });

Solution 14

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.

Solution 15

just serialize the form data and get your problem solved.

data: $('#form_id').serialize(),

Solution 16

formData = new FormData();
formData.append('_token', "{{csrf_token()}}");
formData.append('file', blobInfo.blob(), blobInfo.filename());
xhr.send(formData);

Solution 17

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

Solution 18

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

Solution 19

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() ?>'
        }
    });

Solution 20

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

Solution 21

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}`);
