查询代码有问题吗？
checkPram.put("transaction_id",refund.get("transaction_id"));
checkPram = wxpay.fillRequestData(checkPram);
Map refundQuery = wxpay.refundQuery(checkPram);
e而且退款回调也收不到
s沙箱环境
1.异步接收微信支付退款结果通知的回调地址，通知URL必须为外网可访问的url，不允许带参数
如果参数中传了notify_url，则商户平台上配置的回调地址将不会生效。
2.申请退款，如果接口返回成功，说明已经成功了，登录商户后台检查钱是否已退还；至于调用查询接口提示未查询到订单，多半是订单号传错了，检查一下单号，或者直接去商户后台查询单号，再发起查询
你好，把你的单号以及完整请求参数发一下。看看你那边是不是调用查询的时候传错了单号。谢谢。
