MethodNotAllowedHttpException form error - php

Question

I have created a form in Laravel so here are the following files:
The form that someone should submit some details,
contact.blade.php:
#extends('layouts.layout')
#section('content')
<main role="main">
<section class="jumbotron text-center">
<div class="container">
<h1 class="jumbotron-heading">Laravel demo</h1>
<p class="lead text-muted">Please fill the form</p>
#if(count($errors) > 0)
#foreach($errors->all() as $error)
<div class="alert alert-danger">
{{$error}}
</div>
#endforeach
#endif
</div>
</section>
<div class="album text-muted">
<div class="container">
{!! Form::open(['url' => 'contact/submit']) !!}
{!! csrf_field() !!}
<div class="form-group">
{{Form::label('name', 'Name') }}
{{Form::text('name', 'Enter Name', ['class'=> 'form-control'])}}
</div>
<div class="form-group">
{{Form::label('email', 'E-Mail Address') }}
{{Form::text('email', 'example#gmail.com', ['class'=> 'form-control'])}}
</div>
<div class="form-group">
{{Form::label('message', 'Enter Message') }}
{{Form::textarea('message', 'Enter Message', ['class'=> 'form-control'])}}
</div>
<div>
{{Form::submit('Submit', ['class'=> 'btn btn-primary'])}}
</div>
{!! Form::close() !!}
</div>
</div>
</main>
#endsection
Controller :
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class MessageController extends Controller
{
public function submit(Request $request){
$this->validate($request, [
'name' => 'required',
'email' => 'required'
]);
return 'SUCCESS';
}
}
*
In the Routes web.php file i have included the method as post:
Route::get('/', function () {
return view('home');
});
Route::get('/contact', function () {
return view('contact');
});
Route::post('/contact/submit', 'MessageController#submit');
The error message is " RouteCollection.php (line 251)" .After searching for similar occassions here the problem ussually occurs when in the Routes you use a different method to the specified route method. I'm using POST method for submiting details, I still cannot understand why I get this.
Any help would be appreciated.

Answer 1

Instead of this {!! Form::open(['url' => 'contact/submit']) !!}
Try this.
{!! Form::open(['method'=>'POST','action'=>'MessageController#submit']) !!}

Answer 2

Add the back slash to the url of the form like so :
{!! Form::open(['url' => '/contact/submit']) !!}
