Laravel在多个控制器之间共享变量

Question

I'm using the AppServiceProvider to share specific admin data with all related views.

Now I'd like to share admin data also with all admin related Controllers to replace Auth::guard('admin')->user()->firstname by $admin->firstname.

$id = Auth::guard('admin')->user()->id;
$admin = Admin::findOrFail($id)->first();

How can I share this piece of code with all related Controllers to get for example admin firstname via $admin->firstname?

I would go about creating a global middleware

php artisan make:middleware AdminCarrier

In the middleware, you can add the $admin variable to the $request bag and access it via the Controller.

class AdminCarrier
{
    public function handle($request, Closure $next)
    {
        $id = Auth::guard('admin')->user()->id;
        $admin = Admin::findOrFail($id)->first();

        $request->request->add(['admin' => $admin]);

        return $next($request);
    }
}

In the controller, you can access it via:

$request->admin

Make sure the middleware is global by registering it at Http/Kernel.php
