laravel如何实现多用户体系登录

Bertha 。 2023-07-19 10:51 30阅读 0赞

laraveli添加一个或多个用户表，以admin为例。

部分文件内容可能需要根据实际情况修改

**创建一个Admin模型**

php artisan make:model Admin -m

**编写admins表字段**

Schema::create('admins', function (Blueprint $table) {
    
        $table->increments('id');
    
        $table->string('name')->unique();
    
        $table->string('password');
    
        $table->rememberToken();
    
        $table->timestamps();
    
    });

**编辑admin模型**

<?php
    
    namespace App;
    
    use Illuminate\Notifications\Notifiable;
    
    use Illuminate\Foundation\Auth\User as Authenticatable;
    
    /**
    
     * @property int $id
    
     * @property \Carbon\Carbon $created_at
    
     * @property \Carbon\Carbon $updated_at
    
     */
    
    class Admin extends Authenticatable
    
    {
    
        use Notifiable;
    
        protected $fillable = [
    
            'name', 'password','remember_token'
    
        ];
    
        protected $hidden = [
    
            'password','remember_token'
    
        ];
    
    }

**修改auth.php配置文件**

'guards' => [
    
        ...
    
        'admin' => [
    
            'driver' => 'session',
    
            'provider' => 'admins'
    
        ]
    
    ],
    
    'providers' => [
    
        ...
    
        'admins' => [
    
            'driver' => 'eloquent',
    
            'model' => App\Admin::class,
    
        ]
    
    ],

**在app/Http/Controllers下创建目录Admin/Auth**

**在Admin目录下创建文件HomeController.php(这个文件用来测试登录成功后的跳转页面)**

<?php
    
    namespace App\Http\Controllers\Admin;
    
    use App\Http\Controllers\Controller;
    
    use Illuminate\Http\Request;
    
    class HomeController extends Controller
    
    {
    
        /**
    
         * HomeController constructor.
    
         */
    
        public function __construct()
    
        {
    
            $this->middleware('auth:admin');
    
        }
    
        /**
    
         * Show the application dashboard.
    
         *
    
         * @return \Illuminate\Http\Response
    
         */
    
        public function index()
    
        {
    
            return view('admin.home');
    
        }
    
    }

**使用命令生成一个Request**

php artisan make:request AdminLoginRequest

**此时在app/Http/Request目录下便生成了这个文件，然后编辑这个文件**

<?php
    
    namespace App\Http\Requests;
    
    use Illuminate\Foundation\Http\FormRequest;
    
    class AdminLoginRequest extends FormRequest
    
    {
    
        /**
    
         * 确定用户是否有权发出此请求.
    
         *
    
         * @return bool
    
         */
    
        public function authorize()
    
        {
    
            return true;
    
        }
    
        /**
    
         * 获取适用于请求的验证规则.
    
         *
    
         * @return array
    
         */
    
        public function rules()
    
        {
    
            return [
    
                'name'     => 'required',
    
                'password' => ['required', 'min:6'] //密码必须，最小长度为6
    
            ];
    
        }
    
    }

**在Admin/Auth目录下创建文件LoginController.php**

<?php
    
    namespace App\Http\Controllers\Admin\Auth;
    
    use App\Http\Controllers\Controller;
    
    use App\Http\Requests\AdminLoginRequest;
    
    use Illuminate\Support\Facades\Auth;
    
    class LoginController extends Controller
    
    {
    
        public function showLoginForm()
    
        {
    
            return view('admin.auth.login');
    
        }
    
        public function postLogin(AdminLoginRequest $loginRequest)
    
        {
    
            $data = $loginRequest->only('name', 'password');
    
            $result = Auth::guard('admin')->attempt($data, true);
    
            if ($result) {
    
                return redirect(route('admin.home'));
    
            } else {
    
                return redirect()->back()
    
                    ->with('name', $loginRequest->get('name'))
    
                    ->withErrors(['name' => '用户名或密码错误']);
    
            }
    
        }
    
        public function postLogout()
    
        {
    
            Auth::guard('admin')->logout();
    
            return redirect(route('admin.login.show'));
    
        }
    
    }

**添加路由。打开app/providers/RouteServiceProvider.php**

**在方法mapWebRoutes()方法后面增加一个方法**

protected function mapAdminWebRoutes()
    
        {
    
            Route::middleware('web')
    
                ->prefix('admin')
    
                ->namespace($this->namespace)
    
                ->group(base_path('routes/admin.php'));
    
        }

**在map()方法里调用上面增加的方法**

public function map()
    
        {
    
            $this->mapApiRoutes();
    
            $this->mapAdminWebRoutes();//调用新增的方法
    
            $this->mapWebRoutes();
    
        }

**在routes目录下增加一个路由文件admin.php**

<?php
    
    Route::get('login','Admin\Auth\LoginController@showLoginForm')
    
        ->middleware('guest:admin')
    
        ->name('admin.login.show');
    
    Route::get('/','Admin\HomeController@index')
    
        ->name('admin.home');
    
    Route::post('login','Admin\Auth\LoginController@postLogin')
    
        ->middleware('guest:admin')
    
        ->name('admin.login.post');
    
    Route::post('logout','Admin\Auth\LoginController@postLogout')
    
        ->middleware('auth:admin')
    
        ->name('admin.logout');

**把home.blade.php复制到resources/views/admin下**

**把layouts/app.blade.php复制为layouts/admin.blade.php，修改相应的地方**

<ul class="nav navbar-nav navbar-right">
    
        
    
        @guest('admin')
    
            <li><a href="{
       { route('admin.login.show') }}">admin Login</a></li>
    
        @else
    
        <li class="dropdown">
    
            <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false" aria-haspopup="true">
    
                {
       { Auth::guard('admin')->user()->name }} <span class="caret"></span>
    
            </a>
    
            <ul class="dropdown-menu">
    
                <li>
    
                    <a href="{
       { route('admin.logout') }}"
    
                        onclick="event.preventDefault();
    
                        document.getElementById('logout-form').submit();">
    
                        Logout
    
                    </a>
    
                    <form id="logout-form" action="{
       { route('admin.logout') }}" method="POST" style="display: none;">
    
                        {
       { csrf_field() }}
    
                    </form>
    
                </li>
    
            </ul>
    
        </li>
    
        @endguest
    
    </ul>

**把login.blade.php复制到admin/Auth目录下**

@extends('layouts.admin')@section('content')
    
        <div class="container">
    
            <div class="row">
    
                <div class="col-md-8 col-md-offset-2">

                        <div class="panel-body">
    
                            <form class="form-horizontal" method="POST" action="{

                                {
       { csrf_field() }}
    
                                <div class="form-group{
       { $errors->has('name') ? ' has-error' : '' }}">

                                    <div class="col-md-6">
    
                                        <input id="name" type="text" class="form-control" name="name"
    
                                               value="{
       { old('name') }}" required autofocus>
    
                                        @if ($errors->has('name'))
    
                                            <span class="help-block">

                                        @if ($errors->has('password'))
    
                                            <span class="help-block">
    
                                            <strong>{
       { $errors->first('password') }}</strong>
    
                                        </span>
    
                                        @endif
    
                                    </div>
    
                                </div>
    
                                <div class="form-group">
    
                                    <div class="col-md-8 col-md-offset-4">
    
                                        <button type="submit" class="btn btn-primary">
    
                                            Login
    
                                        </button>
    
                                    </div>
    
                                </div>
    
                            </form>
    
                        </div>
    
                    </div>
    
                </div>
    
            </div>
    
        </div>
    
    @endsection

**数据填充**

php artisan make:seed AdminsTableSeeder

**编辑AdminsTableSeeder.php**

public function run()
    
        {
    
            \App\Admin::insert([
    
                'name'=>'yzha5',
    
                'password'=> bcrypt('123456')
    
            ]);
    
        }
    
    DatabaseSeeder.php
    
    $this->call(AdminsTableSeeder::class);

**文件上传至服务器，登入服务器，执行填充命令**

php artisan migrate
    
    php artisan db:seed

**此时，直接打开[http://xxx/admin][http_xxx_admin]并不会跳转到[http://xxx/admin/login][http_xxx_admin_login]，因此需要处理一些异常。打开app/Exceptions/Handle.php**

**重写unauthenticated()方法。**

use Illuminate\Support\Facades\Route;
    
    protected function unauthenticated($request, AuthenticationException $exception)
    
        {
    
            return starts_with(Route::currentRouteName(), 'admin')
    
                ? redirect(route('admin.login.show'))
    
                : parent::unauthenticated($request, $exception);
    
        }

**完善一下**

以上代码，当admin登录后，再次访问/admin/login这个URI时，会自动跳转到/home这个URI，这是因为guest这个中间件默认跳转到了/home，也就是middleware目录下的RedirectIfAuthenticated.php这个文件。

**解决方法为：**

创建一个中单件，名为：RedirectIfAdminAuthenticated

php artisan make:middleware RedirectIfAdminAuthenticated

**编辑这个文件：**

<?php
    
    namespace App\Http\Middleware;
    
    use Closure;
    
    use Illuminate\Support\Facades\Auth;
    
    class RedirectIfAdminAuthenticated
    
    {
    
        /**
    
         * Handle an incoming request.
    
         *
    
         * @param $request
    
         * @param Closure $next
    
         * @param null $guard
    
         * @return \Illuminate\Http\RedirectResponse|\Illuminate\Routing\Redirector|mixed
    
         */
    
        public function handle($request, Closure $next, $guard = null)
    
        {
    
            if (Auth::guard($guard)->check()) {
    
                return redirect('/admin');
    
            }
    
            return $next($request);
    
        }
    
    }
    
    在Kernel.php中添加一行
    
    protected $routeMiddleware = [
    
            ...
    
            'admin.guest' => \App\Http\Middleware\RedirectIfAdminAuthenticated::class,
    
            ...
    
        ];
    
    更改admin路由，将guest:admin改为admin.guest:admin
    
    Route::get('login','Admin\Auth\LoginController@showLoginForm')
    
        ->middleware('admin.guest:admin')
    
        ->name('admin.login.show');
    
    Route::post('login','Admin\Auth\LoginController@postLogin')
    
        ->middleware('admin.guest:admin')
    
        ->name('admin.login.post');
