Add routing

Copy code The code is as follows:
Route::get('artiles', 'ArticlesController@index');

Create Controller

Copy code The code is as follows:
php artisan make:controller ArticlesController --plain

Modify controller

<&#63;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;
  }

}

Copy after login

You can see the returned JSON results in the browser, cool!

Modify the controller and return to the view

 public function index() {
    $articles = Article::all();

    return view('articles.index', compact('articles'));
  }

Copy after login

Create View

@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

Copy after login

Browse the results, COOL! ! ! !

Show single article

Add route showing details

Copy code The code is as follows:
Route::get('articles/{id}', 'ArticlesController@show');

Among them, {id} is a parameter, indicating the id of the article to be displayed. Modify the controller:

  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'));
  }

Copy after login

Laravel provides more convenient functions to modify the controller:

  public function show($id) {
    $article = Article::findOrFail($id);

    return view('articles.show', compact('article'));
  }

Copy after login

It's cool.

New View

@extends('layout')

@section('content')
  <h1>{{$article->title}}</h1>

  <article>
    {{$article->body}}
  </article>
@stop

Copy after login

Try to access: /articles/1 /articles/2

Modify index view

@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

Copy after login
