微信小程序云开发调用接口cloud.cloudPay.refund(),一条退款接口返回成功,但实际未退款,从微信支付后台下载的退款数据没有这一条退款数据。返回数据如下:{"appid":"wxd2d16a504f24665e","sign":"8359138263BDE4E293F174335D1749F8","returnCode":"SUCCESS","returnMsg":"OK","resultCode":"SUCCESS","mchId":"1800008281","subMchId":"1644216877","nonceStr":"3rrnJg3XMXVHUnkB","transactionId":"4200001988202311157815594706","outTradeNo":"zqc156c3c33620bdc341686944e292dc","outRefundNo":"ret-zqc156c3c33620bdc341686944e292dc","refundId":"50301407822023111650783159103","refundFee":10000,"totalFee":10000,"cashFee":10000,"cashRefundFee":10000,"couponRefundFee":0,"couponRefundCount":0,"couponTypeList":[],"couponRefundIdList":[],"couponRefundFeeList":[],"errCode":0,"errMsg":"cloudPay.refund:ok"}
以functionName中收到的退款回调通知为准。
