Laravel 5.2.31 TokenMismatchException in VerifyCsrfToken.php via HttpRequester

Question

I have this method in 'Flight' controller :

    /**
 * Store a newly created resource in storage.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return \Illuminate\Http\Response
 */
public function store(Request $request)
{
    $arrivalDateTime = $request -> input('arrival.datetime');

    return $arrivalDateTime;
}

and the route:

Route::resource('api/v1/flights', v1\FlightController::class, ['except' => ['create', 'edit']]);

I tried to make POST request using HttpRequester to this address:

http://localhost:8000/api/v1/flights

With this content:

{
"flightNumber":"JWM12345",
"status":"ontime",
"arrival": {
    "datetime":"2016-04-10 22:34:01",
    "iataCode":"A57"
},
"departure": {
    "datetime":"2016-04-10 21:34:01",
    "iataCode":"9C1"
}}

I set the Content Type to 'application/json', then I submit the request and got this error:

What I suppose to do to make my request succeed?

`_token` is required in POST, PUT, DELETE Method. if you are using web middleware by default. — Shahzaib Sheikh, Apr 05 '17 at 18:02
There are options in the HttpRequester, Header and Parameter. I tried both with name '_token' and value '{{ csrf_token() }}', but I still got the same error. — Drizzer Silverberg, Apr 05 '17 at 18:43
Value should be an alphanumeric string for e.g `n2s68OPSzaMVYyiFvvDhlRwvFF55zDwKaQPjX8AS`. Which can be obtained by csrf_token method. — Shahzaib Sheikh, Apr 05 '17 at 18:47

Really easy fix - just add this line:

{{ csrf_field() }}

inside your form. It will create a hidden field that is used for CSRF protection and the error will go away.

I use API debugger named 'HttpRequester', similar to Postman. How and where to add the {{ csrf_field() }} ? – Drizzer Silverberg Apr 05 '17 at 18:48
Right inside your form so

_token is required in POST, PUT, DELETE Method. if you are using web middleware by default.

to obtain token you can create a route which uses csrf_token() function to get token and returns it. make a request to that route to get token which will be like n2s68OPSzaMVYyiFvvDhlRwvFF55zDwKaQPjX8AS and put it in request body like

 {
   "_token":"n2s68OPSzaMVYyiFvvDhlRwvFF55zDwKaQPjX8AS",
   ...
 }

and make requests.

OR

If you don't want to use csrf vaildation on some routes create an new VerifyCsrfToken Class like this in what ever namespace I used this namespace App\Http\Middleware

Now add the routes that you want not be verified by csrf token in $except array.

<?php

namespace App\Http\Middleware;

use Illuminate\Foundation\Http\Middleware\VerifyCsrfToken as BaseVerifier;

class VerifyCsrfToken extends BaseVerifier {

     protected $except = [
        'api/v1/flights'
    ];

 }

now Replace this in kernel.php

protected $middleware = [
    'Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode',
    'Illuminate\Cookie\Middleware\EncryptCookies',
    'Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse',
    'Illuminate\Session\Middleware\StartSession',
    'Illuminate\View\Middleware\ShareErrorsFromSession',
    'Illuminate\Foundation\Http\Middleware\VerifyCsrfToken', // <-- this
 ]

with this

protected $middleware = [
    'Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode',
    'Illuminate\Cookie\Middleware\EncryptCookies',
    'Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse',
    'Illuminate\Session\Middleware\StartSession',
    'Illuminate\View\Middleware\ShareErrorsFromSession',
    'App\Http\Middleware\VerifyCsrfToken', // <-- this
 ]

hope this helps :)

I use the second solution for now, and its works. thanks – Drizzer Silverberg Apr 06 '17 at 18:36 — Drizzer Silverberg, Apr 06 '17 at 18:36

I think you should upgrade to Laravel 5.4, in 5.4 there is a different file named api.php in route folder, there you can write your api routes, which can be accessed by "api/ruote_name".

Cheers.

thanks, maybe it will work if upgrade to 5.4. But I have a problem following laravel update, and still comfort in 5.2. – Drizzer Silverberg Apr 05 '17 at 18:50
You can try one thing- you send the data in request body as raw json format, then your problem will be solved i hope. Normally if Content-type is application/json and you are sending data in form body then token mismatch occur. You can just set the Content-Type to application/json and data in body as raw json. – Kirsten Phukon Apr 06 '17 at 09:07

In regards to what a CSRF token is I think you should read this excellent answer. Laravel validates these requests with middleware called VerifyCsrfToken.

If you want to disable this in Laravel 5.2, open App/Http/Kernel.php

protected $middleware = [
        'Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode',
        'Illuminate\Cookie\Middleware\EncryptCookies',
        'Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse',
        'Illuminate\Session\Middleware\StartSession',
        'Illuminate\View\Middleware\ShareErrorsFromSession',
        'Illuminate\Foundation\Http\Middleware\VerifyCsrfToken',
]

and remove the 'Illuminate\Foundation\Http\Middleware\VerifyCsrfToken' from your middleware array.
