Laravel Logout Using Post Method

In terms of security, it is not wise to use GET method to logout from your applications.

To make more secure, use POST method.

<li> 
<a href="{{ url('/logout') }}" 
onclick="event.preventDefault(); 
document.getElementById('logout-form').submit();"> 

Logout 

</a> 

<form id="logout-form" action="{{ url('/logout') }}" 
method="POST" style="display: none;"> 

{{ csrf_field() }} 
</form> 

</li>

In your controller

public function logout()
{
if(Sentinel::logout()){
return redirect('/');
}
}
