场景：新用户使用 snsapi_userinfo 拉起网页授权，拿到 code 之后通过后台获取 unionId，然后注册用户 问题：上面获取到的 unionId 是我们系统的另一个旧用户，导致新用户登录上了旧用户的账号。另外获取的用户信息中昵称是“微信用户”，如果是快照页模式为什么是获取到一个真实用户的 unionId？ 参考文档： https://developers.weixin.qq.com/doc/offiaccount/OA_Web_Apps/Wechat_webpage_authorization.html#3 使用 appId： wx3ae396a0c53d5239 发生时间： 2023-12-04 18:29:11 用户授权拿到的 code： 051NWZ0w3W5DP13TNh0w3LJxaW3NWZ0e 通过 code 换取 accessToken 日志： {"accessToken":"75__XzdC5_xbOaF-KME8vzqR_8u4WVG4zzFTcnBmhVt-ksm7AK1VG_BsApSHV4U0K11ODUgOiMmm6HJnapivlEUOZhkCzM6GNcMJ********","expiresIn":7200,"openid":"o6o21wAqe1bxm-yf0e3WIldI9z2g","refreshToken":"75_g8vUJ-qSCGrXyCcqqLnS8I4snW_IiZI7khqfwPjchWoNo0OgFJv23tap8-4x244hjZUaizn03SbwX_nzEaUrX-TyF3LP-88zX4jh*******","scope":"snsapi_userinfo"} 拉取用户信息日志： {"openid":"o6o21wAqe1bxm-yf0e3WIldI9z2g","nickname":"微信用户","sex":0,"language":"","city":"","province":"","country":"","headimgurl":"https://thirdwx.qlogo.cn/mmopen/vi_32/Q3auHgzwzM4tkpGVCbufIKWSvnG3ZUWjOfKGcH2OeEVhYn1ltbicREUXHsZa4UDhstDps6KtpvdmTjuVm3RqKuQ/132","privilege":[],"unionid":"o8Yuys2RbDFijvQY-GVkBB5HNlu0"} 新用户实际 unionId: o8YuysznpmRS8aCqTCN0LMciofXU，跟旧用户 o8Yuys2RbDFijvQY-GVkBB5HNlu0 不一样 补充： 新用户实际 openId 无法提供，因为两个用户是通过不同公众号授权，我们系统是根据 unionId 唯一标识用户

我们这边有笔提现订单，一直返回 RECEIVED_MONEY_LIMIT 错误码，因此每天都会用同样订单号重复发起付款请求。但是用户表示这几天没有再提现了，为什么会说【已达到今日付款给此用户额度上限】，订单号是 2000013816886886

不小心删除群发消息的图文，导致图文详情页失效，可以恢复吗？急！！！

https://developers.weixin.qq.com/miniprogram/dev/api-backend/open-api/subscribe-message/subscribeMessage.send.html 文档说的模板 id 有误，原来说的例子是：每个模板参数都会以类型为前缀，例如第一个数字模板参数为 number01.DATA，第二个为 number02.DATA。 然而实际并不是这样，经过测试，模板参数应该是“关键词类型+关键词 kid” 这样组合才对，希望能修改过来。
