【问题描述】：
我正在使用 cs-cart rest API 创建一个安卓应用。我的问题是我想要根据需要的类别，例如父类别的 id 为“0”，所以我只想要那个类别，我可以编辑 URL 以仅获取其 parent_id：“0”的类别
http://www.example.com/api/categories
我也尝试过使用不同的在线工具进行 URL 编码，但都没有成功。
这是我现在得到的 JSON，我需要特定的 parent_id。

【问题讨论】：
-
好吧！！这取决于服务器端是否允许您按父 ID 过滤类别。否则，您需要遍历所有结果并对其进行过滤。
-
500多个品类，上百万种产品，如何配置？这会降低应用速度
