php - 将参数传递给分形更改器(mutator)变换方法

Question

我正在使用 phpleague 的分形包。我有一个像这样的转换类设置

    class ConversationTransformer extends TransformerAbstract
    {

        public function transform (Conversation $conversation, $user)
        {
            return [];
        }
    }

然而，当我尝试访问它时，我得到了 missing argument 2 exception for transform

$user = $this->people->get($this->user());
//conversations
$conversations = $this->conversations->user($user);
return $this->fractal->paginatedCollection($conversations, $user, new ConversationTransformer());

Answer 1

class ConversationTransformer extends TransformerAbstract
{
    private $params = [];

    function __construct($params = [])
    {
        $this->params = $params;
    }

    public function transform (Conversation $conversation)
    {
        //-- $this->params will be used here            

        return [];
    }
}

用这个返回调用它:

 return $this->fractal->paginatedCollection($conversations, new ConversationTransformer(['user' => $user]))
