Question

我第一次尝试 Laravel。我现在正在注册后登录用户，但似乎身份验证助手总是给我空值

这是代码

//REGISTERCONTROLLER
    <?php

namespace App\Http\Controllers\Auth;

use App\Models\User;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Hash;

class RegisterController extends Controller
{
   public function index(){
       return view('auth.register');
   }

   public function store(Request $request)
    {
        $this->validate($request, [
            'name' => 'required|max:255',
            'username' => 'required|max:255',
            'email' => 'required|email|max:255',
            'password' => 'required|confirmed',
        ]);

        User::create([
            'name' => $request->name,
            'username' => $request->username,
            'email' => $request->email,
            'password' => Hash::make($request->password),
        ]);

        auth()->attempt($request->only('email', 'password'));

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

这是仪表板控制器

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class DashboardController extends Controller
{

    public function index(){
        dd(auth()->user());
        return view('dashboard');
    }
}

这里是路由 web.php

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\DashboardController;
use App\Http\Controllers\Auth\RegisterController;

Route::get('/dashboard',[DashboardController::class, 'index'])->name('dashboard');
Route::get('/register',[RegisterController::class, 'index'])->name('register');
Route::post('/register',[RegisterController::class, 'store']);


Route::get('/posts', function () {
    return view('posts.index');
});

另一件事，根据 VSCode，RegisterController 中的“尝试”一词似乎未定义

Answer 1

那是因为 Auth::attempt 使用 bcrypt 对密码进行哈希处理，所以如果您的数据库中的密码未经过哈希处理（bcrypted），则尝试方法将始终失败，因为密码永远不会匹配。请在注册您的用户之前尝试对密码进行哈希处理，并告诉我这是否可以解决问题

Answer 2

这样做：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Auth;
class DashboardController extends Controller
{

    public function index(){
        $user = Auth::user();  //this will return the authenticated user
    return view('dashboard');
    }
}

Answer 3

我认为你需要改变：

$password = Hash::make($request->password);

User::create([
      'name' => $request->name,
      'username' => $request->username,
      'email' => $request->email,
      'password' => $password,
]);

auth()->attempt('email' => $request->email, 'password' => $password);

if (Auth::attempt(['email' => $request->email, 'password' => $password])) {
    // Authentication passed...
    return view('dashboard');
}

Answer 4

我更新了 VSCode，然后它突然工作正常。我什么都没做。

注册后登录，auth()->user() 在 DashboardController 中返回 null
