根据合单支付接口文档的返回参数，并没有一个顶层的trade_state交易状态字段，而是在sub_orders里面有各自的trade_state，这就带来一个问题，如何判断这笔合单支付交易是成功的，是否会存在部分成功部分失败，甚至各种状态组合出现，如果各个子单状态会出现不一致的情况，那就不是一个事务，合单支付也就失去了意义 https://pay.weixin.qq.com/wiki/doc/apiv3/apis/chapter5_1_11.shtml 1、是不是要循环sub_orders判断所有子单的状态为SUCCESS 2、假设3个子单，是否会出现两个成功一个失败的情况

背景： 调用接口：https://api.weixin.qq.com/cgi-bin/user/tag/get?access_token=XXX 官方文档 5. 获取标签下粉丝列表 https://developers.weixin.qq.com/doc/offiaccount/User_Management/User_Tag_Management.html 商户需要将默认组内的所有粉丝转移到其他组，因此第一次使用该接口获取默认组所有openid，同时记录下最后一页的nextOpenId 公众号appid: wx7528cd11366548ad nextOpenid: o4zAjtzy6UvQr6CJ9S1sBw5cSPW8 过了一周，再获取新增粉丝openid，无论是传入上次的nextOpenId还是不传均无法得到返回 1、不传nextopenid，返回 {"errcode":-1,"errmsg":"system error hint: [HFIa.nyWf-iz3MsA] rid: 61e63f19-008b1085-437e3493"} 2、传上一次记录的默认组最后一页nextopenid：o4zAjtzy6UvQr6CJ9S1sBw5cSPW8，返回count=0，但实际上默认组有3000多新增粉丝 [图片] 这个问题早在3年前就发现，迟迟得不到解决，论坛相似问题如下 https://developers.weixin.qq.com/community/pay/doc/00046cf484ca985e35c9d95835b800 https://developers.weixin.qq.com/community/develop/doc/00028e928281c0bafdac172fb5a400 作为开发者，我个人猜测是第二次获取新增关注的粉丝如果不传nextopenid，数据库扫描行数太多导致database 超时，因此我特意记录了第一次的nextopenid备用，结果传入后得到count=0，不知道为何会这样，希望官方能真正说明一下，做不到就给个准信，我们和商户说明情况，换方案即可，现在这样悬而未决，真的很头疼

[图片] 根据后台规则,链接可以包含横杠"-"  但是提交的时候报格式错误，去除横杠就可以提交，但是总不能让商户为此修改域名吧，成本太高了 这个BUG存在很长时间了，你们还是提醒后端改正吧 举例: https://static-pet.xxxxxxx.com/pay/success.html 不可以 https://staticpet.xxxxxxx.com/pay/success.html   可以

请问服务商模式下调用wx.openOfflinePayView接口，是使用服务商的app_secret进行签名求paySign值么？ 我尝试了很多次都不行 {     "appId":"这里是特约商户的小程序，服务商特约商户后台已经绑定到支付商户号",     "timeStamp":"1604481069",     "nonceStr":"OeRaJ0AU4ZwKEVyt",     "package":"mch_id=这里填写的特殊商户号的mch_id",     "signType":"MD5",     "paySign":"42007162D81D8C65A96F2BB7929FEBA3" // 那么这个paySign是使用服务商的app_secret求吗？尝试了下不行 }

无论是小程序发券，还是H5发券，都是需要out_request_no商家发券凭证，并且保证唯一，这个凭证不仅仅是保证幂等性，还是商家和微信关联信息的一个很重要的依据，现在的设计简直匪夷所思！我发券的时候想记录点额外的数据和out_request_no绑定，可是回调的时候偏偏不告诉你out_request_no，这直接导致我们根本无法知道回调给我的券当初是那个out_request_no发的，不知道微信是故意这样设计，还是那史上最垃圾的openid机制一样，打折保护用户隐私的旗号恶心开发者！ https://pay.weixin.qq.com/wiki/doc/apiv3/wxpay/marketing/h5/chapter3_1.shtml https://pay.weixin.qq.com/wiki/doc/apiv3/wxpay/marketing/busifavor/chapter4_1.shtml
