获取纠纷单接口

https://developers.weixin.qq.com/doc/store/shop/API/complaint/api_getcomplaintorder.html#Enum_Res__status

Res.history.item_type 

文档没有120和121枚举值，最多只有113，但是实际有返回这两个值

例如订单号：3736029685501024256，调用接口后返回

{"errcode":0,"errmsg":"ok","order_id":"3736029685501024256","after_sale_order_id":"2000003349267609","history":[{"item_type":60,"time":1777520757,"media_id_list":[],"media_infos":[]},{"item_type":62,"time":1777520748,"media_id_list":[],"media_infos":[]},{"item_type":121,"time":1777520167,"media_id_list":[],"media_infos":[]},{"item_type":120,"time":1777449999,"media_id_list":[],"media_infos":[]},...省略若干返回值
