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' ]; }
'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@R_744_404@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
protected function mapAdminWebRoutes()
{
Route::middleware('web')
->prefix('admin')
->namespace($this->namespace)
->group(base_path('routes/admin.PHP'));
}
public function map()
{
$this->mapApiRoutes();
$this->mapAdminWebRoutes();//调用新增的方法
$this->mapWebRoutes();
}
<?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
$this->call(AdminsTableSeeder::class);
此时，直接打开http://xxx/admin并不会跳转到http://xxx/admin/login，因此需要处理一些异常。打开app/Exceptions/Handle.PHP
重写unauthenticated()方法。
use Illuminate\Support\Facades\Route;
protected function unauthenticated($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');
