return $product;
});
return response()->json(['items' => $items]);

As, given in Laravel docs, Map()method creates a new collection. To modify the values in the current collection, use transform()method.
正如Laravel 文档中给出的那样，Map()方法创建了一个新集合。要修改当前集合中的值，请使用transform()方法。
$items->getCollection()->transform(function ($product) {
$product->name = "Test";
return $product;
});
Also, since, paginator's items is a collection. You can use foreachdirectly on $items
此外，因为分页器的项目是一个集合。您可以foreach直接使用$items
foreach ($items as $item)
{
$item->name = "Test";
}

You should save the data in a collection, work on them, inject them back, something like this:
您应该将数据保存在一个集合中，处理它们，将它们注入回去，如下所示：
$page = Input::get('page', 1);
$data = Item::with('product')->getByPage($page, 10);
$tempItems = $data->items;
$tempItems = $tempItems->map(function($product){
$product->name = "Test";
return $product;
});
$objects = Paginator::make($tempItems, $data->totalItems, 10);
