解密模型值的访问器不起作用

Question

我具有使用访问器和变异器来加密模型值的特征：

trait Encryptable
{
    public function getAttribute($key)
    {
        $value = parent::getAttribute($key);

        if (in_array($key, $this->encryptable)) {
            $value = Crypt::decrypt($value);
            return $value;
        } else {
            return $value;
        }
    }

    public function setAttribute($key, $value)
    {
        if (in_array($key, $this->encryptable)) {
            $value = Crypt::encrypt($value);
        }

        return parent::setAttribute($key, $value);
    }
} 

评论模型

protected $fillable = ['content','user_id','commentable_id', 'commentable_type'];
protected $encryptable = [
    'content'
];

CommentController

public function storePostComment(Request $request, Post $Post)
{
    $this->validate($request, [
        'content' => 'required',
    ]);

    $comment = $post->comments()->create([
        'user_id' => auth()->user()->id,
        'content' => $request->content
    ]);


    dd($comment->content);
    //return new CommentResource($comment);
}

发生的情况是，当我通过return new CommentResource($comment);时，我的评论内容已加密，但是dd($comment->content);解密了我的评论内容。如何解密整个注释对象，以便可以在资源中输出它？

编辑注释资源

class CommentResource extends JsonResource
{
    /**
     * Transform the resource into an array.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return array
     */
    public function toArray($request)
    {
        return [
            'id' => $this->id,
            'content' => $this->content,
            'owner' => $this->owner,
        ];
    }
} 

Answer 1

因为$post->comments()->create()将不会调用setAttribute方法。

根据源代码，雄辩的生成器创建方法调用setRawAttributes：

    public function setRawAttributes(array $attributes, $sync = false)
    {
        $this->attributes = $attributes;

        if ($sync) {
            $this->syncOriginal();
        }

        return $this;
    }

尝试覆盖此方法，如下所示：

    public function setRawAttributes(array $attributes, $sync = false)
    {
        $new_attributes = [];
        foreach($attributes as $key => $val) {
            if (in_array($key, $this->encryptable)) {
                $new_attributes[$key] = Crypt::encrypt($val);
            } else {
                $new_attributes[$key] = $val;
            }
        }


        $this->attributes = $new_attributes;

        if ($sync) {
            $this->syncOriginal();
        }

        return $this;
    }
