将参数传递给分形变换器变换方法

Question

使用phpleague的分形包。我有像这样的变换类设置

    class ConversationTransformer extends TransformerAbstract
    {

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

然而，当我尝试访问它时，我得到了变换的参数2异常

$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 [];
    }
}

使用此返回来调用它：

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