Route::get('artiles', 'ArticlesController@index');
php artisan make:controller ArticlesController --plain
<?php namespace App\Http\Controllers;
use App\Article;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
class ArticlesController extends Controller {
public function index() {
$articles = Article::all();
return $articles;
}
}
可以在浏览器中看到返回的 JSON 结果,cool!
修改控制器,返回视图
public function index() {
$articles = Article::all();
return view('articles.index', compact('articles'));
}
创建视图
@extends('layout')
@section('content')
<h1>Articles</h1>
@foreach($articles as $article)
<article>
<h2>{{$article->title}}</h2>
<div class="body">{{$article->body}}</div>
</article>
@endforeach
@stop
浏览结果,COOL!!!!
添加显示详细信息的路由
Route::get('articles/{id}', 'ArticlesController@show');
其中,{id}
是参数,表示要显示的文章的 id,修改控制器:
public function show($id) {
$article = Article::find($id);
//若果找不到文章
if (is_null($article))
{
//生产环境 APP_DEBUG=false
abort(404);
}
return view('articles.show', compact('article'));
}
laravel 提供了更加方便的功能,修改控制器:
public function show($id) {
$article = Article::findOrFail($id);
return view('articles.show', compact('article'));
}
It's cool.
新建视图
@extends('layout')
@section('content')
<h1>{{$article->title}}</h1>
<article>
{{$article->body}}
</article>
@stop
在浏览器中尝试访问:/articles/1 /articles/2
修改index视图
@extends('layout')
@section('content')
<h1>Articles</h1>
<hr/>
@foreach($articles as $article)
<article>
<h2>
{{--这种方式可以--}}
<a href="/articles/{{$article->id}}">{{$article->title}}</a>
{{--这种方式更加灵活,不限制路径--}}<br>
<a href="{{action('ArticlesController@show', [$article->id])}}">{{$article->title}}</a>
{{--还可以使用--}}<br>
<a href="{{url('/articles', $article->id)}}">{{$article->title}}</a>
</h2>
<div class="body">{{$article->body}}</div>
</article>
@endforeach
@stop
