我在Laravel中获得Auth :: user为null

Question

我使用以下代码为管理员角色创建中间件:

php artisan make:middleware AdminMiddleware

之后,我为登录页面创建了一条路线:

Route::get('admin/login', ['middleware'=>'web','as'=>'admin.login','uses'=>'AdminController@loginView']);
Route::post('admin/login',['middleware'=>'web','as'=>'admin.login','uses'=>'AdminController@login']);
Route::group(['prefix'=>'admin','middleware' => ['auth.admin','web']],     function()
{
    Route::get('/', ['as'=>'admin.home','uses'=>'AdminController@index']);
    Route::get('/home',    ['as'=>'admin.home','uses'=>'AdminController@index']);
});

控制器是

class AdminController extends Controller
{
    //
    function index(){
        return 'welcome';
    }

    function loginView(){
        return view('admin.login');
    }

    function login(Request $request){
        $error = $this->validate($request, [
            'email' => 'required|email',
            'password' => 'required|min:5',
        ]);
        $email = $request->input('email');
        $password = $request->input('password');
        $remember = $request->input('remember');

        if (Auth::attempt(['email' => $email, 'password' => $password,'type'=>'admin'], $remember)) {

            // Authentication passed...
            Auth::login(Auth::user(), $remember);
            return redirect()->route('admin.home');
        }
        else{//('message', 'Login Failed')
            return redirect()->route('admin.login')->withErrors($request->all(), "message")->withInput();
        }
    }
}

在AdminMiddleware中

public function handle($request, Closure $next)
{
    var_dump(Auth::user());
    if(!Auth::check()){
        return redirect()->route('admin.login')->withErrors('You are not logged in');
    }
    elseif ($request->user()->type != 'admin'){
        dd($request->user());
        return redirect()->route('admin.login')->withErrors('You have not authority');
    }
    return $next($request);
}

错误是:我总是在AdminMiddleware中为每个$ request-> user()或Auth:user获取null.

您正以错误的顺序将中间件传递给路由组.

现在您有了这个订单['auth.admin', 'web'],这意味着auth.admin中间件将在web组中间件之前执行,并且由于web包含StartSession中间件,因此您将不需要任何会话auth.admin来获取经过身份验证的用户.

所以只需像这样切换中间件顺序:

Route::group(['prefix'=>'admin','middleware' => ['web', 'auth.admin']], function () {
    // now the session is set up in `web` and then you have it in `auth.admin`
});
