【问题描述】：

我遇到了一个解决方案，可以从 Controller CompanyController.php 中的资源集合中过滤字段

例如下面的代码返回除company_logo之外的所有值

CompanyResource::collection($companies)->hide(['company_logo']);

CompanyResource.php

<?php

namespace App\Http\Resources;

use Illuminate\Http\Resources\Json\JsonResource;


class CompanyResource extends JsonResource

    /**
     * Transform the resource into an array.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */

    protected $withoutFields = [];

    public static function collection($resource)
    
        return tap(new CompanyResourceCollection($resource), function ($collection) 
            $collection->collects = __CLASS__;
        );
    

    // Set the keys that are supposed to be filtered out
    public function hide(array $fields)
    
        $this->withoutFields = $fields;
        return $this;
    

    // Remove the filtered keys.
    protected function filterFields($array)
    
        return collect($array)->forget($this->withoutFields)->toArray();
    

    public function toArray($request)
    
        return $this->filterFields([
            'id' => $this->id,
            'name' => $this->name,
            'email' => $this->email,
            'telephone' => $this->telephone,
            'company_logo' => $this->company_logo,
            'social_links' => $this->social_links,
            
        ]);
    

现在从我的UserResource 我仍然想指定我不想从同一个CompanyResource 返回的字段，但它不再是UserResource 中的集合

用户资源.php

public function toArray($request)
    
        return [
            'id' => $this->id,
            'email' => $this->email,
            'status' => $this->status,
            'timezone' => $this->timezone,
            'last_name' => $this->last_name,
            'first_name' => $this->first_name,
            'tags' => TagResource::collection($this->whenLoaded('tags')),
            'company' => new CompanyResource($this->whenLoaded('company')),
            
        ];
    

所以我的想法是能够在'company' => new CompanyResource($this->whenLoaded('company')), 上指定排除字段 在这里停留了一段时间。

【参考方案1】：

经过研究，我找到了解决问题的有效解决方案

'company' => CompanyResource::make($this->whenLoaded('company'))->hide(['company_logo']),

下面的我不能灵活使用：

'company' => new CompanyResource($this->whenLoaded('company')),
