Auth :: user()在模块__construct()上返回null [英] Auth::user() returns null on Module __construct()

问题描述

我使用 laravel-modules 创建了一个名为Article的新模块.一些后端路由需要身份验证，我添加了auth中间件和附加的权限view_backend.我正在使用 https://github.com/spatie/laravel-permission 程序包执行以下任务:权限.

I created a new Module named Article using laravel-modules. Some backend routes needed authentication and i added auth middleware and an additional permission view_backend. I am using https://github.com/spatie/laravel-permission package for role-permissions.

问题是当我尝试访问路由admin/article/posts时，它提示我登录符合预期.但是登录后，它在Auth::user()的__construct()方法上显示为空；

the issue is when i try to access the route admin/article/posts it prompts me the login as expected. But after login it show null on __construct() method for Auth::user();

我添加了#204 中提到的web中间件没有解决问题.你能指导我解决这个问题吗?我的项目是在Laravel 5.6上，并使用最新版本的Laravel-Modules

I added web middleware as mentioned on #204 but it did not solve the issue. Can you please guide me to resolve this? My project is on Laravel 5.6 and using the latest version of Laravel-Modules

Route::group(['namespace' => 'Modules\Article\Http\Controllers\Backend', 'as' => 'backend.article.', 'middleware' => ['web', 'auth', 'can:view_backend'], 'prefix' => 'admin/article'], function () {

    Route::resource("posts", "PostsController");
});

推荐答案

根据文档:

在以前的Laravel版本中，您可以在控制器的构造函数中访问会话变量或经过身份验证的用户.从来没有打算将其作为框架的显式功能.在Laravel 5.3中，由于中间件尚未运行，因此您无法在控制器的构造函数中访问会话或经过身份验证的用户.

In previous versions of Laravel, you could access session variables or the authenticated user in your controller's constructor. This was never intended to be an explicit feature of the framework. In Laravel 5.3, you can't access the session or authenticated user in your controller's constructor because the middleware has not run yet.

作为替代，您可以直接定义基于Closure的中间件 在控制器的构造函数中.使用此功能之前，请确保 您的应用程序正在运行Laravel 5.3.4或更高版本:

As an alternative, you may define a Closure based middleware directly in your controller's constructor. Before using this feature, make sure that your application is running Laravel 5.3.4 or above:

public function __construct()
{
    $this->middleware(function ($request, $next) {
        $this->projects = Auth::user()->projects;

        return $next($request);
    });
}

或者您可以键入提示:

public function index(Request $request)
{
    $projects = $request->user()->projects;

    $value = $request->session()->get('key');
}
