在laravel中为整个控制器分配用户值 [英] Assign user values for whole controller in laravel

问题描述

我正在开发我的第一个laravel应用，我想根据用户角色和ID在控制器上管理不同的操作.

I'm developing my first laravel app, and I want to manage different actions on my controllers depending on user role and id.

所以我想知道是否可以向我的控制器添加两个私有变量 $ userRole 和 $ userId ，这样我就不需要调用 auth()-> user()->角色和 auth()-> user()-> id .

So I'm wondering if I can add two private variables $userRole and $userId to my controller so I don't need to call auth()->user()->role and auth()->user()->id in each single action method.

我尝试在__construct方法上初始化变量，但是中间件此时似乎未处于活动状态，并且无法访问user()参数.

I've tried to initiate the variables on __construct method, but the middleware seems not to be active at this point, and cannot access user() parameters.

我也尝试只给变量赋 auth()-> user()->任何，但是php似乎在编译时加载了这些值，因此方法无法用于初始化.

I've tried also to just assign my variables with the auth()->user()->whatever, but seems that php load these values on compile time, so methods cannot be used for the initialization.

现在，我想知道是否应该为此创建自己的中间件(我将在几个不同的Controller类上使用它)还是应该使用会话.

Now I'm wondering if I should create my own middleware for this (I will use it on several different Controller classes) or if I should use sessions.

对此有何建议?

推荐答案

在创建控制器之前，会话中间件尚未运行.

The session middleware has not ran by the time your controller is created.

您可以添加一个控制器中间件，该中间件可以为您分配这些值，因为中间件将在堆栈中运行:

You can add a controller middleware that can assign these values for you, as the middleware will run in the stack:

public function __construct()
{
    $this->middleware(function ($request, $next) {
        $this->userId = $request->user()->id;
        $this->roleId = $request->user()->role;

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