laraveli新增一個或多個使用者表，以admin為例。。
部分檔案內容可能需要根據實際情況修改
建立一個Admin模型
php artisan make:model Admin -m編寫admins表欄位
Schema::create(`admins`, function (Blueprint $table) {
$table->increments(`id`);
$table->string(`name`)->unique();
$table->string(`password`);
$table->rememberToken();
$table->timestamps();
});編輯admin模型
<?php
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配置檔案
`guards` => [
...
`admin` => [
`driver` => `session`,
`provider` => `admins`
]
],
`providers` => [
...
`admins` => [
`driver` => `eloquent`,
`model` => AppAdmin::class,
]
],在app/Http/Controllers下建立目錄Admin/Auth
在Admin目錄下建立檔案HomeController.php(這個檔案用來測試登入成功後的跳轉頁面)
<?php
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`);
}
}使用命令生成一個Request
php artisan make:request AdminLoginRequest此時在app/Http/Request目錄下便生成了這個檔案，然後編輯這個檔案
<?php
namespace AppHttpRequests;
use IlluminateFoundationHttpFormRequest;
class AdminLoginRequest extends FormRequest
{
/**
* 確定使用者是否有權發出此請求.
*
* @return bool
*/
public function authorize()
{
return true;
}
/**
* 獲取適用於請求的驗證規則.
*
* @return array
*/
public function rules()
{
return [
`name` => `required`,
`password` => [`required`, `min:6`] //密碼必須，最小長度為6
];
}
}在Admin/Auth目錄下建立檔案LoginController.php
<?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`, $loginRequest->get(`name`))
->withErrors([`name` => `使用者名稱或密碼錯誤`]);
}
}
public function postLogout()
{
Auth::guard(`admin`)->logout();
return redirect(route(`admin.login.show`));
}
}新增路由。開啟app/providers/RouteServiceProvider.php
在方法mapWebRoutes()方法後面增加一個方法
protected function mapAdminWebRoutes()
{
Route::middleware(`web`)
->prefix(`admin`)
->namespace($this->namespace)
->group(base_path(`routes/admin.php`));
}在map()方法裡呼叫上面增加的方法
public function map()
{
$this->mapApiRoutes();
$this->mapAdminWebRoutes();//呼叫新增的方法
$this->mapWebRoutes();
}在routes目錄下增加一個路由檔案admin.php
<?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複製到resources/views/admin下
把layouts/app.blade.php複製為layouts/admin.blade.php，修改相應的地方
<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複製到admin/Auth目錄下
@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資料填充
php artisan make:seed AdminsTableSeeder編輯AdminsTableSeeder.php
public function run()
{
AppAdmin::insert([
`name`=>`yzha5`,
`password`=> bcrypt(`123456`)
]);
}DatabaseSeeder.php
$this->call(AdminsTableSeeder::class);檔案上傳至伺服器，登入伺服器，執行填充命令
php artisan migrate
php artisan db:seed此時，直接開啟http://xxx/admin並不會跳轉到http://xxx/admin/login，因此需要處理一些異常。開啟app/Exceptions/Handle.php
重寫unauthenticated()方法。
use IlluminateSupportFacadesRoute;
protected function unauthenticated($request, AuthenticationException $exception)
{
return starts_with(Route::currentRouteName(), `admin`)
? redirect(route(`admin.login.show`))
: parent::unauthenticated($request, $exception);
}完善一下
以上程式碼，當admin登入後，再次訪問/admin/login這個URI時，會自動跳轉到/home這個URI，這是因為guest這個中介軟體預設跳轉到了/home，也就是middleware目錄下的RedirectIfAuthenticated.php這個檔案。
解決方法為：
建立一箇中單件，名為：RedirectIfAdminAuthenticated
php artisan make:middleware RedirectIfAdminAuthenticated編輯這個檔案：
<?php
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中新增一行
protected $routeMiddleware = [
...
`admin.guest` => AppHttpMiddlewareRedirectIfAdminAuthenticated::class,
...
];更改admin路由，將guest:admin改為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`);
