看上去是把header+body又插入进了一次body，header并没放到http header里

Thx for your issue, pls check this version v3.0.11

[FourLeafTec]

更新3.0.11，微信响应

{"code":"PARAM_ERROR","detail":{"location":null,"value":["/body/appid","/body/mchid"]},"message":"请求中含有未在API文档中定义的参数"}

日志中body部分多了appid和mchid两个节点:

request body:{"amount":{"currency":"CNY","refund":1,"total":1},"appid":"${appid}","mchid":"${mchid}","notify_url":"${notify_url}","out_refund_no":"${out_refund_no}","reason":"取消订单","transaction_id":"${transaction_id}"}

这个有点奇怪了
居然不需要这两个字的

[Matrix-X]

看来要区别对待了，大部分v3的接口，需要传这三个参数

[FourLeafTec]

微信支付这块比较麻烦，每个口都不一样

小程序和jsapi这块的情况是：
JSAPI下单：两个都要
查询订单：mchid,但是都传似乎也不报错
关闭订单：mchid,但是都传似乎也不报错
调起支付：appid
申请退款：都不能传
查询退款：都不能传
账单那几个接口我还没做到

接口规则的统一情况来说，也算腾讯老传统了，内部都是不一致的

[Matrix-X]

我提交了到dev分支
你能不能先用dev分支测试一下刚才那个退款的接口？

没问题的话，我打版本

[Matrix-X]

强烈要求你这位专业人士，加入我们微信群 ;-)

[FourLeafTec]

develop版本检出v3.0.0-beta9.0.20230301083122-e2df9327a3ed
退款成功了

目前知道这个版本下订单，接收支付通知，查询支付结果，退款，接收退款通知，查询退款结果，微信统一消息推送是没问题的
我项目还没到整体测试阶段，没有完整的自动测试用例

我也不常做微信支付这块，正好这个活用到了而已，抽空我从前面的issue里找下贵公司的微信群加一下吧

最新版本更新到：

v3.0.12
