五分钟教你使用laravel实现登陆注册功能

废话不多说直接上代码，你就负责，复制粘贴就可以了，其他的我给你整

1，创建 Laravel 项目：

composer create-project --prefer-dist laravel/laravel login-demo

2，设置数据库连接：在 .env 文件中配置相关的数据库信息。

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=login_demo
DB_USERNAME=root
DB_PASSWORD=

3，创建数据库迁移文件：

php artisan make:migration create_users_table

在 database/migrations 目录下生成一个新的迁移文件，在 up 方法中编写创建用户表的代码：

Schema::create('users', function (Blueprint $table) {
    $table->id();
    $table->string('name');
    $table->string('email')->unique();
    $table->timestamp('email_verified_at')->nullable();
    $table->string('password');
    $table->rememberToken();
    $table->timestamps();
});

4，运行数据库迁移：

php artisan migrate

5，编写用户模型：

php artisan make:model User

在 app/Models/User.php 文件中添加如下代码：

namespace AppModels;

use IlluminateContractsAuthMustVerifyEmail;
use IlluminateDatabaseEloquentFactoriesHasFactory;
use IlluminateFoundationAuthUser as Authenticatable;
use IlluminateNotificationsNotifiable;

class User extends Authenticatable implements MustVerifyEmail
{
    use HasFactory, Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name',
        'email',
        'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password',
        'remember_token',
    ];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];
}

6，创建认证系统：

php artisan make:auth

7，配置路由：在 routes/web.php 文件中添加以下代码，将登录注册页面与相应的控制器方法进行绑定。

use AppHttpControllersAuthLoginController;
use AppHttpControllersAuthRegisterController;

Route::get('/', function () {
    return view('welcome');
});

Route::get('/login', [LoginController::class, 'showLoginForm'])->name('login');
Route::post('/login', [LoginController::class, 'login']);
Route::post('/logout', [LoginController::class, 'logout'])->name('logout');

Route::get('/register', [RegisterController::class, 'showRegistrationForm'])->name('register');
Route::post('/register', [RegisterController::class, 'register']);

8，编写控制器：创建控制器方法，用于处理用户提交的表单数据，并将其插入到数据库中。
在 app/Http/Controllers/Auth/RegisterController.php 文件中添加如下代码：

namespace AppHttpControllersAuth;

use AppHttpControllersController;
use AppModelsUser;
use IlluminateFoundationAuthRegistersUsers;
use IlluminateSupportFacadesHash;
use IlluminateSupportFacadesValidator;

class RegisterController extends Controller
{
    use RegistersUsers;

    protected $redirectTo = '/home';

    public function __construct()
    {
        $this->middleware('guest');
    }

    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => ['required', 'string', 'max:255'],
            'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
            'password' => ['required', 'string', 'min:8', 'confirmed'],
        ]);
    }

    protected function create(array $data)
    {
        return User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => Hash::make($data['password']),
        ]);
    }
}

9，创建视图：
在 resources/views/auth/register.blade.php 文件中添加如下代码：

@extends('layouts.app')

@section('content')
<div class="card">
    <div class="card-header">{{ __('Register') }}</div>

    <div class="card-body">
        <form method="POST" action="{{ route('register') }}">
            @csrf

            <div class="form-group row">
                <label for="name" class="col-md-4 col-form-label text-md-right">{{ __('Name') }}</label>

                <div class="col-md-6">
                    <input id="name" type="text" class="form-control @error('name') is-invalid @enderror" name="name" value="{{ old('name') }}" required autocomplete="name" autofocus>

                    @error('name')
                        <span class="invalid-feedback" role="alert">
                            <strong>{{ $message }}</strong>
                        </span>
                    @enderror
                </div>
            </div>

            <div class="form-group row">
                <label for="email" class="col-md-4 col-form-label text-md-right">{{ __('E-Mail Address') }}</label>

                <div class="col-md-6">
                    <input id="email" type="email" class="form-control @error('email') is-invalid @enderror" name="email" value="{{ old('email') }}" required autocomplete="email">

                    @error('email')
                        <span class="invalid-feedback" role="alert">
                            <strong>{{ $message }}</strong>
                        </span>
                    @enderror
                </div>
            </div>

            <div class="form-group row">
                <label for="password" class="col-md-4 col-form-label text-md-right">{{ __('Password') }}</label>

                <div class="col-md-6">
                    <input id="password" type="password" class="form-control @error('password') is-invalid @enderror" name="password" required autocomplete="new-password">

                    @error('password')
                        <span class="invalid-feedback" role="alert">
                            <strong>{{ $message }}</strong>
                        </span>
                    @enderror
                </div>
            </div>

            <div class="form-group row">
                <label for="password-confirm" class="col-md-4 col-form-label text-md-right">{{ __('Confirm Password') }}</label>

                <div class="col-md-6">
                    <input id="password-confirm" type="password" class="form-control" name="password_confirmation" required autocomplete="new-password">
                </div>
            </div>

            <div class="form-group row mb-0">
                <div class="col-md-6 offset-md-4">
                    <button type="submit" class="btn btn-primary">
                        {{ __('Register') }}
                    </button>
                </div>
            </div>
        </form>
    </div>
</div>
@endsection

10，运行项目：
启动 Laravel 开发服务器，运行以下命令：

php artisan serve

在浏览器中访问 http://localhost:8000/register 可以看到注册页面，填写表单信息并点击注册按钮即可将数据插入到数据库中。

以上是一个简单示例，实际开发中可能还需要增加其他功能和优化代码结构谢谢！仅供参考不是大神，只是爱折腾
