如何在《拉威尔8》中实现《记住我》？ [英] How to implement Remember me in Laravel 8?

问题描述

我有一个登录表单和一个"记住我"复选框。如果用户在上次登录时选中了"记住我"复选框，我希望自动填写用户名和密码，但目前不起作用。我正在使用在Laravel中构建的LoginController。

LoginController：

<?php


namespace AppHttpControllersAuth;
use AppHttpControllersController;
use AppProvidersRouteServiceProvider;
use IlluminateFoundationAuthAuthenticatesUsers;
use IlluminateHttpRequest;
use IlluminateValidationValidationException;

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')],
            ]
        );
    }
}

login.blade.php：

@extends('layouts.app')

@section('content')
<div class="topMargin container">
  <br><br>
  <div class="row justify-content-center">
      <div class="col-md-8">

                              @if ($errors->has('identity'))

推荐答案

看起来您使用的是Laravel提供的默认身份验证，这意味着您不需要在Http/Controllers/Auth/LoginController到中执行任何操作，如果您在views/auth/login.blade.php表单中具有默认表单输入名称值，则请记住用户！

您唯一需要确保的是在users表中存储remember_token字段。

参见：https://laravel.com/docs/8.x/authentication#remembering-users
