原文發(fā)表在我的個(gè)人網(wǎng)站：Laravel 5 系列入門教程（二）【最適合中國(guó)人的 Laravel 教程】

  本教程示例代碼見(jiàn)：https://github.com/johnlui/Learn-Laravel-5

  
  
大家在任何地方卡住，最快捷的解決方式就是去看我的示例代碼。

我們將改變學(xué)習(xí)路線，不再像 Laravel 4 教程那樣先構(gòu)建登錄系統(tǒng)。在本篇教程中，我們將一起構(gòu)建 Pages 的管理功能，嘗試 Laravel 的路由和 PHP 的命名空間。

Laravel 中的路由，跟其他 PHP 框架一樣，作用是把各種請(qǐng)求分流到各個(gè)控制器。

在 learnlaravel5/app/Http/routes.php 的末尾添加以下代碼：

phpRoute::group(["prefix" => "admin", "namespace" => "Admin"], function()
{
  Route::get("/", "AdminHomeController@index");
});

bashphp artisan make:controller Admin/AdminHomeController

phpuse AppPage;

phppublic function index()
{
  return view("AdminHome")->withPages(Page::all());
}

php@extends("app")

@section("content")

          @foreach ($pages as $page)
            

            

              
{{ $page->title }}
              

                

                  {{ $page->body }}
