Below is my code for AuthController
<?php
namespace App\Http\Controllers\Auth;
use App\User;
use Validator;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\ThrottlesLogins;
use Illuminate\Foundation\Auth\AuthenticatesAndRegistersUsers;
//use App\Http\Requests\Request;
use Request;
use View;
use Hash;
use DB;
use Auth;
class AuthController extends Controller
{
/*

| Registration & Login Controller

|
| This controller handles the registration of new users, as well as the
| authentication of existing users. By default, this controller uses

use AuthenticatesAndRegistersUsers, ThrottlesLogins;

Below is my Route Code
Route::get('/',array('uses'=>'Auth\AuthController#showLogin') );
Route::post('/login',array('uses'=>'Auth\AuthController#doLogin'));
//Route::get('/login',array('uses'=>'Login#showLogin') );
Route::group(['middleware' => ['web', 'auth.basic']], function(){
Route::get('/home',['uses'=>'Home#getHome']);
Route::get('/logout',array('uses'=>'Auth\AuthController#doLogout') );
});

Answer 1

Update:
Add the auth middleware to specific route
Route::group(['middleware' => ['web']], function(){
Route::get('/',array('uses'=>'Auth\AuthController#showLogin') );
Route::post('/login',array('uses'=>'Auth\AuthController#doLogin'));
Route::get('/home',['uses'=>'Home#getHome'])->middleware('auth');//update
Route::get('/logout',array('uses'=>'Auth\AuthController#doLogout') );
});
To redirect to intended page after login replace your doLogin() function with following:
public function doLogin()
{
$input = Request::all();
$pass = Hash::make($input['password']);
if (Auth::attempt(['user_name' => $input['username'], 'password' => $input['password']])) {
return redirect()->intended('/home');//This line is changed
}
else
{
return redirect('/');
}
}
Explaination:
intended() method redirects the user to the previous page, from where the user is redirected to login page. It expects a default route as a parameter, where user will be sent if he has came here directly.
Update 2:
add doLogout in your AuthController's constructor:
public function __construct()
{
$this->middleware($this->guestMiddleware(), ['except' => 'doLogout']);
}

Answer 2

You can simply override $username in AuthController by writing protected $username = 'username'.
