创建一个index主页列出所有文章

生成路由

app/Http/routes.php

Route::get('/articles','ArticlesController@index');

生成一个controller

php artisan make:controller ArticlesController

namespace App\Http\Controllers;use App\Articles;  //当你使用Articles这个model的时候，phpstorme会帮你默认导入这个类use Illuminate\Http\Request;use App\Http\Requests;class ArticlesController extends Controller{    //    public function index(){  //因为路由里面我们使用了ArticlesController@index，所以这里是index方法        $articles = Articles::all();         //这里需要注意的是这个Articles是我们创建的那个Articles的model，在phpstorme会有提示，这里的all方法是返回这个model查询到的所有数据，这些数据是提前输入好的        return $articles;    }}

访问localhost:8000/articles会出现以下内容，laravel会默认返回json格式的数据

运用已有的blade知识，配置一个layout

例如

resources/views/layout/app.blade.phplayout只是一个概念，这个文件主要是为了创造一个模板容器，用来处理那些可以复用的代码，例如一些html的head，body标签

< !DOCTYPE html><html><head>    <title>Laravel</title>    <!-- 新 Bootstrap 核心 CSS 文件 -->    <link rel="stylesheet" href="//cdn.bootcss.com/bootstrap/3.3.5/css/bootstrap.min.css"/></head><body>    <div class="container">        @yield('content')    </div>    @yield(('footer'))</body></html>

创建刚才控制器指定的那个blade文件

resources/views/articles/index.blade.php

@extends('layout.app')@section('content')    <h1 id="hello">hello</h1>    <hr />    @foreach($articles as $article)  //循环输出        <h2 id="article-title">{{$article->title}}</h2>        <article>            <div>                {{$article->content}}            </div>        </article>    @endforeach@stop

创建一个文章页，列出单个文章

单个文章，需要有文章id在url里面区分，所以特意建立了一个新的路由和一个新的controller方法show

Route::get('/articles/{id}','ArticlesController@show'); {id}传入变量参数，用大括号来标识，传入变量到controller的show方法

app/Http/Controllers/ArticlesController.php

class ArticlesController extends Controller{    //    public function index(){        $articles = Articles::all();//        return $articles;        return view('articles.index',compact('articles'));    }    public function show($id){    //获取从路由传入的$id变量        $article = Articles::find($id); //使用laravel提供的find方法查询数据库//        return $articles;        return view('articles.show',compact('article'));    }}

resources/views/articles/show.blade.php

@extends('layout.app')@section('content')    <h1 id="hello">hello</h1>    <hr />    @foreach($articles as $article)        {{--<h2 id="a-href-articles-article-id-article-title-a"><a href="/articles/{{$article->id}}">{{$article->title}}</a></h2>--}}{{--        <h2 id="a-href-url-articles-article-id-article-title-a"><a href="{{url('articles',$article->id)}}">{{$article->title}}</a></h2>--}}        <h2 id="a-href-action-ArticlesController-show-article-id-article-title-a"><a href="{{action('ArticlesController@show',[$article->id])}}">{{$article->title}}</a></h2>        //这里有三种方法来传递变url量到blade中，第一种是直接写的，第二种是通过url方法，使用的路由方法，第三种是通过action方法，使用的是controller方式        <article>            <div>                {{$article->content}}            </div>        </article>    @endforeach@stop
