Laravel：Dingo / API分页自定义根密钥

本文介绍了Laravel：Dingo / API分页自定义根密钥的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

根据文档，我使用了分页，我的代码看起来像这样

$ users = User :: paginate（50）; return $ this-> response-> paginator（$ users，new UserTransformer）;

不幸的是，响应根键是数据

{data：[ {id：1，username：superuser ...

我想更改数据键因为在我的情况下，emberjs得到这个响应，并尝试与不存在的基准模型建立链接，关键是需要设置与ember模型相同的名称，以防万一RESTAdapter。

我已经在响应中尝试了一些参数，但没有改变

return $ this-> response-> paginator（$ users，new UserTransformer，['key'=>'users']）;

或

return $ this-> response-> paginator（$ users，new UserTransformer，['identifier'=>'users']）;

没有任何工作，我被卡住了数据键。

有人有解决方案吗？

提前谢谢。

解决方案

我设法解决了我的问题。

我不修改api.php配置，变压器保持不变

'transformer'=> env（'API_TRANSFORMER'，Dingo\Api\Transformer\Adapter\Fractal :: class），

首先我创建一个新的序列化器

// app / Api / V1 / Serializers / CustomJsonSerializer.php <？php命名空间App \Api\V1\Serializers; 使用League \Fractal\Pagination\CursorInterface; 使用League \Fractal\Pagination\PaginatorInterface; 使用League\Fractal\Serializer\SerializerAbstract; / ** *在项目中创建一个新的Serializer * / 使用League \Fractal\Serializer\ArraySerializer; class CustomJsonSerializer扩展ArraySerializer { public function collection（$ resourceKey，array $ data） { if（$ resourceKey === false） { return $ data; } 返回数组（$ resourceKey？：'data'=> $ data）; } public function item（$ resourceKey，array $ data） { if（$ resourceKey === false）{ return $ data ; } 返回数组（$ resourceKey？：'data'=> $ data）; } }

我将新的自定义序列化程序设置在AppServiceProviders

// app \Providers\AppServiceProviders.php <？php 命名空间App \Providers; 使用Illuminate\Support\ServiceProvider; 使用Dingo\Api\Transformer\Adapter\Fractal; 使用League\Fractal\Manager; 使用App \Api\V1\Serializers\CustomJsonSerializer; class AppServiceProvider扩展ServiceProvider { / ** *引导任何应用程序服务。 * * @return void * / public function boot（） { $ this-> app ['Dingo\Api\\ setTransformer\Factory'] - > setAdapter（function（$ app）{ $ fractal = new Manager（）; $ fractal-> setSerializer（new CustomJsonSerializer（））; 返回新的分形（$ fractal）; }）; } / ** *注册任何应用服务。 * * @return void * / public function register（） { // } }

我希望它会帮助ppl：）

I've developed an API with Laravel 5 and Dingo/API.

Following the documentation, i used pagination and my code look like that

$users = User::paginate(50); return $this->response->paginator($users, new UserTransformer);

Unfortunately, the response root key is "data"

{ "data": [ { "id": 1, "username": "superuser", ......

I'd like to change the "data" key to a custom one, because in my case, emberjs get this response and try to make a link with a "datum" model which doesn't exist, the key need to be set with the same name as the ember model in case of a RESTAdapter.

I already tried some parameters in the response but nothing change

return $this->response->paginator($users, new UserTransformer, ['key' => 'users']);

or

return $this->response->paginator($users, new UserTransformer, ['identifier' => 'users']);

Nothing work, i'm stuck with the "data" key.

Is someone have a solution ?

Thank you in advance.

解决方案

I managed to fix my problem.

I don't modify the api.php configuration, transformer stay the same

'transformer' => env('API_TRANSFORMER', Dingo\Api\Transformer\Adapter\Fractal::class),

Firstly i create a new serializer

// app/Api/V1/Serializers/CustomJsonSerializer.php <?php namespace App\Api\V1\Serializers; use League\Fractal\Pagination\CursorInterface; use League\Fractal\Pagination\PaginatorInterface; use League\Fractal\Serializer\SerializerAbstract; /** * Create a new Serializer in your project */ use League\Fractal\Serializer\ArraySerializer; class CustomJsonSerializer extends ArraySerializer { public function collection($resourceKey, array $data) { if ($resourceKey === false) { return $data; } return array($resourceKey ?: 'data' => $data); } public function item($resourceKey, array $data) { if ($resourceKey === false) { return $data; } return array($resourceKey ?: 'data' => $data); } }

And i set my new custom serializer inside the AppServiceProviders

// app\Providers\AppServiceProviders.php <?php namespace App\Providers; use Illuminate\Support\ServiceProvider; use Dingo\Api\Transformer\Adapter\Fractal; use League\Fractal\Manager; use App\Api\V1\Serializers\CustomJsonSerializer; class AppServiceProvider extends ServiceProvider { /** * Bootstrap any application services. * * @return void */ public function boot() { $this->app['Dingo\Api\Transformer\Factory']->setAdapter(function ($app) { $fractal = new Manager(); $fractal->setSerializer(new CustomJsonSerializer()); return new Fractal($fractal); }); } /** * Register any application services. * * @return void */ public function register() { // } }

I hope it'll help ppl :)
