Laravel 5.2，auth :: check登录后返回true，但重定向后返回false [英] Laravel 5.2, auth::check return true after login but false after redirect

问题描述

我正在尝试使用laravel 5.2内置的身份验证系统.登录名似乎正常运行，如果我用Auth :: check()替换return语句，它将返回true.但是当我重定向到"/"时，Auth :: check()在我的Auth中间件中突然返回false.

I'm trying to use the authentication system that comes built in with laravel 5.2. The login seems to be working correctly, if I replace the return statement with Auth::check(), it returns true. But when I redirect to '/', Auth::check() suddenly returns false in my Auth middleware.

会话创建方法:

public function create(Request $request) 
{
    $email = $request->email;
    $password = $request->password;

    if(Auth::attempt(['email' => $email, 'password' => $password])) {
        return redirect()->intended('/'); // returns true when replaced with Auth::check();
    }

    return redirect("login");

}

验证中间件:

public function handle($request, Closure $next, $guard = null)
{
    if (Auth::guest()) {
        if ($request->ajax() || $request->wantsJson()) {
            return response('Unauthorized.', 401);
        } else {
            return var_dump(Auth::check()); // returns false
        }
    }

    return $next($request);
}

路由文件:

Route::post('/create-session', 'SessionController@create');
Route::get('/logout', 'SessionController@logout');
Route::get('/login', function() {
   return view('login');
});

Route::group(['middleware' => ['web', 'auth']], function(){
   Route::get('/', 'HomeController@getIndex');
});

推荐答案

所有需要会话(Auth使用)的路由都必须应用'web'中间件.

ALL routes that require sessions (which Auth uses) must have the 'web' middleware applied.

也:

您的Auth::check()是在仅在Auth::guest()为true的情况下运行的代码块中完成的. Auth::guest()是Auth::check()的倒数.

Your Auth::check() is being done in a code block that only runs if Auth::guest() is true. Auth::guest() is the inverse of Auth::check().

因此，您在中间件中说:如果当前用户是访客(未认证)，请检查他们是否是已认证用户，这时始终为假.

So you are saying in your middleware: If the current user is a guest (not authenticated), check if they are an authenticated user, which will always be false at this point.

更新:

根据您的评论:不要将经过身份验证的中间件添加到"web"组.否则，您将永远无法打通网络"路线，除非您在进行此更改之前已通过身份验证.如果这样做，您甚至将无法登录.

Based on your comments: Do not add the authenticate middleware to the 'web' group. You will never be able to hit a 'web' route if you do this unless you were authenticated before you made this change. You are removing the ability to even be able to login if you do this.
