H5微信支付申请退款官方文档地址：https://pay.weixin.qq.com/wiki/doc/apiv3/apis/chapter3_3_9.shtml 请求URL：https://api.mch.weixin.qq.com/v3/refund/domestic/refunds

你们请求URL: https://api.mch.weixin.qq.com/v3/ecommerce/refunds/apply

我将请求地址换成 https://api.mch.weixin.qq.com/v3/refund/domestic/refunds 参数按照官方文档要求，退款成功。

麻烦作者帮我看看，谢谢。
