Laravel5: TokenMismatchException in compiled.php line 3123:

THE SITUATION:

Sorry in advance if it has already been asked. But no matter what I can never make it works.

I am using Laravel 5 as API.

I have a simple function to edit a task.

I am testing it through my web app or through Postman.

I am always getting this error:

TokenMismatchException in compiled.php line 3123:

THE CODE:

The function:

public function updateTask(Request $request)
{
    $id = $request->input('id');

    $task = Task::find($id);
    $task->name = $request->input('name');
    $task->type = $request->input('type');
    $task->save();

    return $task;
}

The route:

Route::group(['middleware' => ['web']], function () {

    Route::post('update', 'TaskController@updateTask');
});

THE QUESTION:

Why I am getting that error?

Answer

I solved it by inserting the route name as an item in the array $except in the file:

app/http/Middleware/VerifyCsrfToken.php

Like this:

/**
 * The URIs that should be excluded from CSRF verification.
 *
 * @var array
 */
 protected $except = [

     'update'
 ];
