我可以使用转换器来转换来自API而不是来自数据库的数据吗？ - Laravel/Fractal

Question

我一直在使用laravel来构建我的API.我使用变换器来转换模型对象的数据.

现在我没有数据库,而是来自API的响应作为数据源,我想将这些数据转换回用户,但我无法这样做.

我的控制器

 public function rocByName(Request $request)
    {
        try {
            $this->roc_by_name_validator->with( $request->all() )->passesOrFail();
            $company_name = $request->input('company_name');
            $result = $this->my_service->getDetailsByName($company_name); //$result has the response object from the API which I want to transform and give it as a response.

             return $this->response->collection($result,new OnboardingTransformer()); //Tried using tranformer like this
        }
        catch (ValidatorException $e) {

            dd($e);

        }

    }

我的变形金刚

<?php

namespace Modules\Onboarding\Transformers;

use League\Fractal\TransformerAbstract;
use App\Entities\OnboardingEntity;  //I dont have an entity since the response is coming from an API!! What will give here?

/**
 * Class OnboardingTransformerTransformer
 * @package namespace App\Transformers;
 */
class OnboardingTransformer extends TransformerAbstract
{

    /**
     * Transform the \OnboardingTransformer entity
     * @param \OnboardingTransformer $model
     *
     * @return array
     */
    public function transform(OnboardingEntity $data_source) 
    {
        return [
            'company_name'         => $data_source->company_name,
        ];
    }
}

这里的OnboardingEntity是指理想地来自数据库的数据.这里我不是从数据库中获取数据,而是我的数据来自API源.我该怎么做呢 我在这里很少被灌输.有人可以给出解决方案吗？

$ result有以下响应

[
    [
        {
            "companyID": "U72400MHTC293037",
            "companyName": "pay pvt LIMITED"
        },
        {
            "companyID": "U74900HR2016PT853",
            "companyName": "dddd PRIVATE LIMITED"
        }
    ]
]

$this->response->collection旨在获取对象的集合，而不是数组。然后所有这些对象都将根据需要进行转换，即转换 OnboardingEntity 对象。因此，首先您应该将输入数组转换为对象集合。我上面的示例是如何做到的（您应该将其更改为您自己的输入数组）

$data = json_decode('[
    [
        {
            "companyID": "U72400MHTC293037",
            "companyName": "pay pvt LIMITED"
        },
        {
            "companyID": "U74900HR2016PT853",
            "companyName": "dddd PRIVATE LIMITED"
        }
   ]
]');  

$data = collect( array_map( function($ob){
    return (new OnboardingEntity($ob));
}, $data[0]));

然后将 OnboardingEntity 对象的集合传递给$this->response->collection方法，如下所示 $this->response->collection($data,new TestTransformer());
