项目是微信小程序，通过接口的方式将一笔订单进行退款，在商户后台可以查询到退款成功且钱已回到用户卡上。但是退款成功后无法触发配置的退款notify_url，该地址是公网的且是用了HTTPS的地址。单独可直接访问。测试时在该回调地址中放了一个简单的创建文件语句，也就是一但触发回调第一步就可以发现文件被创建即回调触好。目前的问题是这个创建文件的动作根据未执行，也就是退款回调根据没被触发过。所有的测试都未使用所谓的沙箱环境。API安全证书都配置好了，因为退款接口都能正常使用。

我的url可以正常访问，但是未收到退款回调通知

chooseMessageFile已经按照要求授权但是小程序端还是不能应用。
