    laravel如何实现多用户体系登录

    藏色散人藏色散人2020-03-30 08:56:14转载1188
    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

    推荐:laravel教程

    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">
        <!-- Authentication Links -->
        @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 panel-default">
                        <div class="panel-heading">Admin Login</div>
                        <div class="panel-body">
                            <form class="form-horizontal" method="POST" action="{{ route('admin.login.post') }}">
                                {{ csrf_field() }}
                                <div class="form-group{{ $errors->has('name') ? ' has-error' : '' }}">
                                    <label for="name" class="col-md-4 control-label">E-Mail Address</label>
                                    <div class="col-md-6">
                                        <input id="name" type="text" class="form-control" name="name"
                                               value="{{ old('name') }}" required autofocus>
                                        @if ($errors->has('name'))
                                            <span class="help-block">
                                            <strong>{{ $errors->first('name') }}</strong>
                                        </span>
                                        @endif
                                    </div>
                                </div>
                                <div class="form-group{{ $errors->has('password') ? ' has-error' : '' }}">
                                    <label for="password" class="col-md-4 control-label">Password</label>
                                    <div class="col-md-6">
                                        <input id="password" type="password" class="form-control" name="password" required>
                                        @if ($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并不会跳转到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');
