dwij laraadmin - 多角色登录

要实现多角色登录功能，可以按照以下步骤进行操作：

1. 安装 dwij/laraadmin 包：

composer require dwij/laraadmin

2. 生成用户管理模块：

php artisan la:install

3. 生成多角色登录功能： 在 app\Http\Controllers\Auth 目录下创建一个新的控制器 LoginController.php，并添加以下代码：

<?php

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;

class LoginController extends Controller
{
    use AuthenticatesUsers;

    protected $redirectTo = '/home';

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

    public function showLoginForm()
    {
        return view('auth.login');
    }

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

        $credentials = $request->only('email', 'password');

        if (Auth::attempt($credentials)) {
            // 用户登录成功
            return redirect()->intended($this->redirectTo);
        }

        return back()->withErrors([
            'email' => '登录失败，请检查邮箱和密码是否正确。',
        ]);
    }
}

4. 修改 app\Http\Controllers\Auth\RegisterController.php，添加以下代码：

protected function create(array $data)
{
    $user = User::create([
        'name' => $data['name'],
        'email' => $data['email'],
        'password' => bcrypt($data['password']),
    ]);

    // 创建用户角色关联
    $role = Role::where('name', 'user')->first();
    if ($role) {
        $user->attachRole($role);
    }

    return $user;
}

5. 修改 app\User.php，添加以下代码：

use Dwij\Laraadmin\Traits\LaraAdminUser;

class User extends Authenticatable
{
    use Notifiable, LaraAdminUser;
}

6. 创建视图 resources\views\auth\login.blade.php，添加以下代码：

<form method="POST" action="{{ route('login') }}">
    @csrf

    <div class="form-group row">
        <label for="email" class="col-md-4 col-form-label text-md-right">邮箱地址</label>

        <div class="col-md-6">
            <input id="email" type="email" class="form-control{{ $errors->has('email') ? ' is-invalid' : '' }}" name="email" value="{{ old('email') }}" required autofocus>

            @if ($errors->has('email'))
                <span class="invalid-feedback" role="alert">
                    <strong>{{ $errors->first('email') }}</strong>
                </span>
            @endif
        </div>
    </div>

    <div class="form-group row">
        <label for="password" class="col-md-4 col-form-label text-md-right">密码</label>

        <div class="col-md-6">
            <input id="password" type="password" class="form-control{{ $errors->has('password') ? ' is-invalid' : '' }}" name="password" required>

            @if ($errors->has('password'))
                <span class="invalid-feedback" role="alert">
                    <strong>{{ $errors->first('password') }}</strong>
                </span>
            @endif
        </div>
    </div>

    <div class="form-group row">
        <div class="col-md-6 offset-md-4">
            <div class="form-check">
                <input class="form-check-input" type="checkbox" name="remember" id="remember" {{ old('remember') ? 'checked' : '' }}>

                <label class="form-check-label" for="remember">
                    记住我
                </label>
            </div>
        </div>
    </div>

    <div class="form-group row mb-0">
        <div class="col-md-8 offset-md-4">
            <button type="submit" class="btn btn-primary">
                登录
            </button>

            <a class="btn btn-link" href="{{ route('password.request') }}">
                忘记密码？
            </a>
        </div>
    </div>
</form>

7. 更新路由 routes\web.php，添加以下代码：
