Laravel, Auth::user() in controller
提问by roy
Laravel framework- Why aren't I able to use Auth::user(), (to see if user has been logged in) in the controller of the laravel project. Is the Session not connected to the controller?
Laravel 框架 - 为什么我不能在 Laravel 项目的控制器中使用 Auth::user(),（查看用户是否已登录）。Session 没有连接到控制器吗？
HomeController.php
家庭控制器.php
public function isauthorized(){
if (Auth::user()){
return View::make('home.basic')
->with('basic1', 'Authorized');
}else{
return View::make('home.basic')
->with('basic1', 'Not Authorized');
}
}
My login system is working and the session is always set when logged in. When I call the function Auth::user() in the View or in routes.php, it is succesfull. But when I call the function in the controller, it is false. Help please.
我的登录系统正在运行，并且会话总是在登录时设置。当我在视图或 routes.php 中调用函数 Auth::user() 时，它是成功的。但是当我在控制器中调用该函数时，它是错误的。请帮忙。

The problem is that you haven't included the Auth facade.
问题是你没有包含 Auth 门面。
In your HomeController.php do:
在你的 HomeController.php 中：
use Illuminate\Support\Facades\Auth;

If you're on Laravel 5.x, you'll probably have the auth middleware component. That might be the missing link.
如果您使用的是 Laravel 5.x，您可能会拥有 auth 中间件组件。那可能是缺失的环节。
I often use a pattern like this in my controllers:
我经常在我的控制器中使用这样的模式：
public function __construct()
{
$this->middleware('auth');
$this->user = \Auth::user();
}
then you can
然后你可以
if ($this->user .. )
if ($this->user .. )
or
或者
if ($this->user->can('something'))with Entrust or similar
if ($this->user->can('something'))与委托或类似

Just add the following in your controller library.
只需在您的控制器库中添加以下内容。
use Illuminate\Support\Facades\Auth;

You need to use the Auth facade in the controller;
您需要在控制器中使用 Auth 门面；
add this line just before class definition.
在类定义之前添加这一行。
use Auth;

To see if a user is loged in don't use Auth::user(). Use Auth::check()instead.
要查看用户是否已登录，请不要使用Auth::user(). 使用Auth::check()来代替。
if (Auth::check()){
return View::make('home.basic')->with('user', Auth::user());
}

I have the same problem. The solution I've found, is to not use \Auth::user() (it returns null). Instead, go through the guard like this: \Auth::guard('mrm')->User(). Obviously replace 'mrm' with whatever auth guard you are using.
我也有同样的问题。我发现的解决方案是不使用 \Auth::user() （它返回 null）。取而代之的是，经过这样的后卫：\Auth::guard('mrm')->User()。显然，用您正在使用的任何身份验证保护替换“mrm”。
This works, correctly returning the current user even when Auth::User returns null, and you can also use other methods on it - e.g. \Auth::guard('mrm')->check()instead of \Auth::check()(which always returns false).
这有效，即使当 Auth::User 返回 null 时也能正确返回当前用户，并且您也可以在其上使用其他方法 - 例如\Auth::guard('mrm')->check()代替\Auth::check()（它总是返回 false）。
No idea why the Auth facade doesn't work, but at least there is an alternative that does.
不知道为什么 Auth 外观不起作用，但至少有一个替代方案。

in your controllers constructor:
在您的控制器构造函数中：
public function __construct(){
$this->middleware('auth');
}

additionally, you can also use the auth()helper without adding the facade in your controller. (i.e. auth()->user()
此外，您还可以使用auth()帮助程序，而无需在控制器中添加外观。（IEauth()->user()

Use Auth::check()function to check if user is logged or not
使用Auth::check()函数检查用户是否登录
