1、在调通收付通app支付的情况下，将代码复制，修改相关appId,请求地址，并增加openId 参数的情况下报400 badRequest 是啥情况

微信收付通支付，会存在部分二级商户收单成功 部分不成功吗？ 比如用户支付100，共涉及到3个二级商户。其中两个二级商户收单成功，一个收单不成功吗？

请求信息： {     "combine_appid":"wxe0a*********",     "sub_orders":[         {             "mchid":"15********",             "out_trade_no":"202003291955yj",             "description":"测试关闭",             "sub_mchid":"158********"         }     ],     "combine_out_trade_no":"202003291955" } 请求地址:https://api.mch.weixin.qq.com/v3/combine-transactions/out-trade-no/202003291955/close API文档地址：https://pay.weixin.qq.com/wiki/doc/apiv3/wxpay/pay/combine/chapter3_4.shtml 返回信息：400BadRequest

签名都是复制的 https://wechatpay-api.gitbook.io/wechatpay-api-v3/qian-ming-zhi-nan-1/qian-ming-sheng-cheng 最下方的demo。 请求header也添加了 httpPost.addHeader("content-type", "application/json"); httpPost.addHeader("Authorization", "WECHATPAY2-SHA256-RSA2048"+" "+ sign); httpPost.addHeader("Accept", "application/json"); 请求的参数是自己模拟的，但是请求的返回码一直是400 BadRequest
