laravel使用transformer转化器和分页

参考 https://github.com/Cyvelnet/laravel5-fractal

composer require  league/fractal 0.14.0

composer require Cyvelnet/laravel5-fractal

打开config/app.php

在providers中添加

Cyvelnet\Laravel5Fractal\Laravel5FractalServiceProvider::class,

在 aliases中添加

'Fractal' => Cyvelnet\Laravel5Fractal\Facades\Fractal::class,

在app文件夹下创建Transformers文件夹

在该文件夹下创建ArticleTransformer.php

< ?php

namespace App\Transformers;
use App\Model\Article;
use League\Fractal\TransformerAbstract;
class ArticleTransformer extends TransformerAbstract {
    public
    function transform(Article $article) {
        return [
                'id' = >$article - >id, 
                'title' = >$article - >title, 
                'content' = >$article - >content, 
                'created_at' = >$article - >created_at - >diffForHumans(), 
               ];
    }
} 

在控制器中使用

namespace App\Http\Controllers\Api;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use App\Repositories\ArticleRepository;
use Fractal;
use App\Transformers\ArticleTransformer;

class IndexController extends Controller
{
    public function __construct(ArticleRepository $articleRepository)
    {
        $this->articleRepository = $articleRepository;
    }

    /*获取所有文章*/
    public function index()
    {
        $articles = $this->articleRepository->all();
        $data = Fractal::collection($articles, new ArticleTransformer())->getArray();

        return apiResponse(200, 'ok', $data);
    }

}
