在此之前，我已经浏览了与我的问题一致的大部分答案，几乎我有一个undefined variable用户。
我希望能够显示在 Jmeter 板上的注册用户，我用这个代码之前，它的工作，但不适用于此应用程序。

Undefined variable: user (View: /Applications/MAMP/htdocs/eli/resources/views/dashboard.blade.php)

字符串
这是我的代码

UserController.php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use App\User;
use App\Http\Requests;

class UserController extends Controller
{
    public function getWelcome()
    {

      return view('welcome');

    }

    public function getDashboard()
    {
        $users = User::all();

        return view('dashboard', compact('users'));
    }

    public function userSignUp(Request $request)
    {

        $this->validate($request, [
            'email' => 'required|email|unique:users',
            'first_name' => 'required|max:120',
            'password' => 'required|min:4'

        ]);

        $email = $request['email'];
        $first_name = $request['first_name'];
        $password = bcrypt($request['password']);

        $user = new User();
        $user->email = $email;
        $user->first_name = $first_name;
        $user->password = $password;

        $user->save();


        return redirect()->route('dashboard');

    }
    public function postSignin(Request $request)
    {
        $remember = $request->input('remember_me');

        if(Auth::attempt(['email'=> $request['email'], 'password' => $request['password']], $remember )){
            return redirect()->route('dashboard');
        }

        return redirect()->back();
    }

}
