如何在没有数据库的情况下在Laravel中对用户进行身份验证？

php artisan make:model User

use Illuminate\Foundation\Auth\AuthenticatesUsers;

class User extends Authenticatable
{
    use AuthenticatesUsers;

    // 配置认证相关的属性
    protected $guard = 'web';
    protected $redirectTo = '/home';

    // 配置认证相关的方法
    public function username()
    {
        return 'email';
    }
}

Route::get('/login', 'AuthController@showLoginForm')->name('login');
Route::post('/login', 'AuthController@login');
Route::post('/logout', 'AuthController@logout')->name('logout');

class AuthController extends Controller
{
    public function showLoginForm()
    {
        return view('auth.login');
    }

    public function login(Request $request)
    {
        // 在这里进行用户身份验证的逻辑
    }

    public function logout(Request $request)
    {
        // 在这里进行用户退出登录的逻辑
    }
}

public function login(Request $request)
{
    $credentials = $request->only('email', 'password');

    if ($this->validateCredentials($credentials)) {
        // 认证成功，将用户信息存入Session
        $user = new User();
        $user->email = $credentials['email'];
        $request->session()->put('user', $user);

        return redirect()->intended('/home');
    }

    return redirect()->back()->withErrors([
        'email' => 'Invalid credentials',
    ]);
}

private function validateCredentials($credentials)
{
    // 在这里进行用户身份验证的逻辑，例如检查用户名和密码是否匹配
    // 这里使用Session来模拟用户数据
    $user = $request->session()->get('user');

    return $user && $user->email === $credentials['email'] && $user->password === $credentials['password'];
}

Route::middleware('auth')->group(function () {
    // 受保护的路由
    Route::get('/home', 'HomeController@index')->name('home');
});
