在Laravel5.5中使用公共基类

在Laravel5.5中要使用公共基类，要这么搞

直接上代码（请忽略我那丑陋的Publi）

namespace App\Http\Controllers\Admin\Publi;
use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Routing\Controller;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;
use Illuminate\Support\Facades\Redirect;
class BaseController extends Controller
{
    use AuthorizesRequests, DispatchesJobs, ValidatesRequests;

    //构造函数
    public function __construct() {
        $this->middleware(function ($request, $next) {
            //未登录的处理
            $this->dosomething();
            return $next($request);
        });
    }

    //做一些操作 Laravel规定要这样
    public function dosomething() {
        //如果未登录，则跳转到登录页面
        if(session('username')==''){
            Redirect::to('/login')->send();
        }
    }

这样就可以了
