如何在 Laravel 8 中实现记住我？

Question

I have a login form and a remember me checkbox. I want the username and the password to be automatically filled in if the user checked the remember me checkbox on the previous login, but it is not working for now. I'm using the LoginController that was built in Laravel.

LoginController:

<?php


namespace App\Http\Controllers\Auth;
use App\Http\Controllers\Controller;
use App\Providers\RouteServiceProvider;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;
use Illuminate\Validation\ValidationException;

class LoginController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Login Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles authenticating users for the application and
    | redirecting them to your home screen. The controller uses a trait
    | to conveniently provide its functionality to your applications.
    |
    */
    use AuthenticatesUsers;

    /**
     * Where to redirect users after login.
     *
     * @var string
     */
    protected $redirectTo = RouteServiceProvider::DASHBOARD;

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest')->except('logout');
    }

    /**
     * Check either username or email.
     * @return string
     */
    public function username()
    {
        $identity  = request()->get('identity');
        $fieldName = filter_var($identity, FILTER_VALIDATE_EMAIL) ? 'email' : 'name';
        request()->merge([$fieldName => $identity]);
        return $fieldName;
    }

     /**
     * Validate the user login.
     * @param Request $request
     */
    protected function validateLogin(Request $request)
    {
        $this->validate(
            $request,
            [
                'identity' => 'required|string',
                'password' => 'required|string',
            ],
            [
                'identity.required' => 'Username or email is required',
                'password.required' => 'Password is required',
            ]
        );
    }
    /**
     * @param Request $request
     * @throws ValidationException
     */
    protected function sendFailedLoginResponse(Request $request)
    {
        $request->session()->put('login_error', trans('auth.failed'));
        throw ValidationException::withMessages(
            [
                'error' => [trans('auth.failed')],
            ]
        );
    }
}

Any help would be greatly appreciated!

Answer 1

public function webLoginPost(Request $request)
{
    $this->validate($request, [
        'email' => 'required|email',
        'password' => 'required',
    ]);


    $remember_me = $request->has('remember_me') ? true : false; 


    if (auth()->attempt(['email' => $request->input('email'), 'password' => $request->input('password')], $remember_me))
    {
        $user = auth()->user();
        dd($user);
    }else{
        return back()->with('error','your username and password are wrong.');
    }
}

Looks like you are using the default Authentication provided by Laravel, meaning you do not need to do anything in your Http/Controllers/Auth/LoginController to remember the user if you have the default form input name values in the views/auth/login.blade.php form, which it looks like you do!

The only thing you need to ensure is that in your users table you store a remember_token field.
