本篇教程中，我们将利用 Laravel 5 自带的开箱即用的 Auth 系统对我们的后台进行权限验证，并构建出前台页面，对 Pages 进行展示。
1. 权限验证
后台地址为 http://localhost:88/admin ，我们的所有后台操作都将在此页面或其子页面下进行。利用 Laravel 5 提供的 Auth，我们只需要改动很少部分的路由代码便可以实现权限验证功能。
首先，将路由组的代码改为：
Route::group(['prefix' => 'admin', 'namespace' => 'Admin', 'middleware' => 'auth'], function()
{
Route::get('/', 'AdminHomeComtroller@index');
Route::resource('pages', 'PagesController');
});
上面代码中只有一处变化：给 `Route::group()` 的第一个参数（一个数组）增加了一项 `'middleware' => 'auth'`。现在访问 http://localhost:88/admin ，应该会跳转到登陆页面。如果没有跳转，也不要惊慌，从右上角退出，重新进入即可。
我们的个人博客系统并不想让人随便注册，下面我们将改动部分路由代码，只保留基本的登录、注销功能。
删掉：
Route::controllers([
'auth' => 'Auth\AuthController',
'password' => 'Auth\PasswordController',
]);
增加：
Route::get('auth/login', 'Auth\AuthController@getLogin');
Route::post('auth/login', 'Auth\AuthController@postLogin');
Route::get('auth/logout', 'Auth\AuthController@getLogout');
带有权限验证的最小化功能的后台已经完成，这个后台目前只管理 Page（页面）这一种资源。接下来我们将构建前台页面，把 Pages 展示出来。
2. 构建首页
先整理路由代码，将路由的最上面的两行：
改成：
我们将直接使用 HomeController 来支撑我们的前台页面展示。
此时可以删除 learnlaravel5/app/Http/Controllers/WelcomeController.php 控制器文件和 learnlaravel5/resources/views/welcome.blade.php 视图文件。
修改 learnlaravel5/app/Http/Controllers/HomeController.php 为：
<?php namespace App\Http\Controllers;
use App\Page;
class HomeController extends Controller {
public function index()
{
return view('home')->withPages(Page::all());
}
}
控制器构造完成。
`view('home')->withPages(Page::all())` 这句话实现以下功能：
渲染 learnlaravel5/resources/views/home.blade.php 视图文件
把变量 $pages 传进视图，$pages = Page::all()
Page::all() 调用的是 Eloquent 中的 all() 方法，返回 pages 表中的所有数据。
接下来我们开始写视图文件：
首先，我们将创建一个前端页面的统一的外壳，即 `
` 部分及 `#footer` 部分。新建 learnlaravel5/resources/views/_layouts/default.blade.php 文件（文件夹请自行创建）：
<!DOCTYPE html>
<html lang="zh-CN">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Learn Laravel 5</title>
<link href="/css/app.css" rel="stylesheet">
<!-- Fonts -->
<link href='http://fonts.useso.com/css?family=Roboto:400,300' rel='stylesheet' type='text/css'>
</head>
<body>
<div class="container" style="margin-top: 20px;">
@yield('content')
<div id="footer" style="text-align: center; border-top: dashed 3px #eeeeee; margin: 50px 0; padding: 20px;">
©2015 <a href="http://lvwenhan.com">JohnLui</a>
</div>
</div>
</body>
</html>
修改 learnlaravel5/resources/views/home.blade.php 文件为：
@extends('_layouts.default')
@section('content')
<div id="title" style="text-align: center;">
<h1 id="Learn-Laravel">Learn Laravel 5</h1>
<div style="padding: 5px; font-size: 16px;">{{ Inspiring::quote() }}</div>
</div>
<hr>
<div id="content">
<ul>
@foreach ($pages as $page)
<li style="margin: 50px 0;">
<div class="title">
<a href="{{ URL('pages/'.$page->id) }}">
<h4 id="page-title">{{ $page->title }}</h4>
</a>
</div>
<div class="body">
<p>{{ $page->body }}</p>
</div>
</li>
@endforeach
</ul>
</div>
@endsection
第一行 `@extends('_layouts.default')` 代表这个页面是 learnlaravel5/resources/views/_layouts/default.blade.php 的子视图。此时 Laravel 的 视图渲染系统会首先载入父视图，再将此视图中的 @section('content') 里面的内容放入到父视图中的 @yield('content') 处进行渲染。
访问 http://localhost:88/ ，可以得到如下页面：
2. 构建 Page 展示页
首先增加路由。在路由文件的第一行下面增加一行：
新建控制器 learnlaravel5/app/Http/Controllers/PagesController.php，负责单个 page 的展示：
<?php namespace App\Http\Controllers;
use App\Page;
class PagesController extends Controller {
public function show($id)
{
return view('pages.show')->withPage(Page::find($id));
}
}
新建视图 learnlaravel5/resources/views/pages/show.blade.php 文件：
@extends('_layouts.default')
@section('content')
<h4>
<a href="/">⬅️返回首页</a>
</h4>
<h1 id="page-title">{{ $page->title }}</h1>
<hr>
<div id="date" style="text-align: right;">
{{ $page->updated_at }}
</div>
<div id="content" style="padding: 50px;">
<p>
{{ $page->body }}
</p>
</div>
@endsection
全部完成，检验成果：点击首页之中任意一篇文章的标题，进入文章展示页，你会看到以下页面：
至此，前台展示页面全部完成，教程三结束。
以上所述就是本文的全部内容了，希望能够对大家学习Laravel5框架有所帮助。
