php 多用户登录,laravel 实现多用户体系登录

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

namespace App;

use IlluminateNotificationsNotifiable;

use IlluminateFoundationAuthUser as Authenticatable;

/**

* @property int $id

* @property CarbonCarbon $created_at

* @property CarbonCarbon $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' => AppAdmin::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)

namespace AppHttpControllersAdmin;

use AppHttpControllersController;

use IlluminateHttpRequest;

class HomeController extends Controller

{

/**

* HomeController constructor.

*/

public function __construct()

{

$this->middleware('auth:admin');

}

/**

* Show the application dashboard.

*

* @return IlluminateHttpResponse

*/

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

namespace AppHttpRequests;

use IlluminateFoundationHttpFormRequest;

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

namespace AppHttpControllersAdminAuth;

use AppHttpControllersController;

use AppHttpRequestsAdminLoginRequest;

use IlluminateSupportFacadesAuth;

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

Route::get('login','AdminAuthLoginController@showLoginForm')

->middleware('guest:admin')

->name('admin.login.show');

Route::get('/','AdminHomeController@index')

->name('admin.home');

Route::post('login','AdminAuthLoginController@postLogin')

->middleware('guest:admin')

->name('admin.login.post');

Route::post('logout','AdminAuthLoginController@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

@guest('admin')

@else

{{ Auth::guard('admin')->user()->name }}

• οnclick="event.preventDefault();

  document.getElementById('logout-form').submit();">

  Logout

  {{ csrf_field() }}

@endguest

把login.blade.php复制到admin/Auth目录下

@extends('layouts.admin')

@section('content')

@endsection

数据填充

php artisan make:seed AdminsTableSeeder

编辑AdminsTableSeeder.php

public function run()

{

AppAdmin::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app/Exceptions/Handle.php

重写unauthenticated()方法。

use IlluminateSupportFacadesRoute;

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：

namespace AppHttpMiddleware;

use Closure;

use IlluminateSupportFacadesAuth;

class RedirectIfAdminAuthenticated

{

/**

* Handle an incoming request.

*

* @param $request

* @param Closure $next

* @param null $guard

* @return IlluminateHttpRedirectResponse|IlluminateRoutingRedirector|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' => AppHttpMiddlewareRedirectIfAdminAuthenticated::class,

...

];

更改admin路由，将guest:admin改为admin.guest:admin

Route::get('login','AdminAuthLoginController@showLoginForm')

->middleware('admin.guest:admin')

->name('admin.login.show');

Route::post('login','AdminAuthLoginController@postLogin')

->middleware('admin.guest:admin')

->name('admin.login.post');
