laraveli添加一個或多個用戶表，以admin為例。

部分文件內(nèi)容可能需要根據(jù)實際情況修改

推薦：laravel教程

創(chuàng)建一個Admin模型

php artisan make:model Admin -m

編寫admins表字段

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配置文件

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

在app/Http/Controllers下創(chuàng)建目錄Admin/Auth

在Admin目錄下創(chuàng)建文件HomeController.php(這個文件用來測試登錄成功后的跳轉(zhuǎn)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文件，然后編輯這個文件

<?php
namespace AppHttpRequests;
use IlluminateFoundationHttpFormRequest;
class AdminLoginRequest extends FormRequest
{
 /**
 * 確定用戶是否有權(quán)發(fā)出此請求.
 *
 * @return bool
 */
 public function authorize()
 {
 return true;
 }
 /**
 * 獲取適用于請求的驗證規(guī)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目錄下創(chuàng)建文件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' => '用戶名或密碼錯誤']);
 }
 }
 public function postLogout()
 {
 Auth::guard('admin')->logout();
 return redirect(route('admin.login.show'));
 }
}

添加路由。打開app/providers/RouteServiceProvider.php

在方法mapWebRoutes()方法后面增加一個方法

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

在map()方法里調(diào)用上面增加的方法

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

在routes目錄下增加一個路由文件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復(fù)制到resources/views/admin下

把layouts/app.blade.php復(fù)制為layouts/admin.blade.php，修改相應(yīng)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復(fù)制到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

數(shù)據(jù)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);

文件上傳至服務(wù)器，登入服務(wù)器，執(zhí)行填充命令

php artisan migrate
php artisan db:seed

此時，直接打開http://xxx/admin并不會跳轉(zhuǎn)到http://xxx/admin/login，因此需要處理一些異常。打開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

以上代碼，當(dāng)admin登錄后，再次訪問/admin/login這個URI時，會自動跳轉(zhuǎn)到/home這個URI，這是因為guest這個中間件默認(rèn)跳轉(zhuǎn)到了/home，也就是middleware目錄下的RedirectIfAuthenticated.php這個文件。

解決方法為：

創(chuàng)建一個中單件，名為：RedirectIfAdminAuthenticated

php artisan make:middleware RedirectIfAdminAuthenticated

編輯這個文件：

<?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中添加一行
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');
