+# 会会微信小程序虚拟支付回调（待双方确认）
+
+本项目为会会服务端预留固定回调地址：
+
+`POST https://digital.99hui.com/api/token/payment/huihui/virtual/notify`
+
+回调报文及签名协议尚未与会会确认。以下是本项目实现的拟议对接契约，双方确认并安全交换密钥后才能进行测试支付。接口代码部署与会会联调通过是两个独立状态。它不替代现有微信直连回调 `/api/token/payment/wechat/virtual/notify`。
+
+请求体为 JSON，成功支付示例：
+
+```json
+{
+  "orderNo": "AV202610150000000000000001",
+  "paymentNo": "会会侧唯一支付流水号",
+  "status": "SUCCESS",
+  "amountCents": 1000,
+  "productId": "points_plan_1",
+  "openId": "微信小程序用户 OpenID",
+  "env": 1
+}
+```
+
+`amountCents` 单位为分，`env` 为微信虚拟支付环境（0 正式、1 沙箱）。非成功结果可发送 `status: "FAILED"`，但不会入账。订单号、支付流水号和状态必填；成功结果还必须提供金额、商品 ID、OpenID、环境。仅在订单属于微信虚拟支付，且上述信息与本地订单、套餐、用户一致时入账。重复成功通知不会重复发放积分；同一支付流水号不能用于其他订单。
+
+请求头：
+
+- `X-Huihui-Timestamp`：Unix 秒级时间戳，允许与本服务时间相差不超过 300 秒。
+- `X-Huihui-Signature`：小写十六进制 HMAC-SHA256，密钥为双方线下安全交换、服务端配置的 `HUIHUI_VIRTUAL_CALLBACK_SECRET`（至少 32 字符），待签名数据为 `时间戳 + 换行符 + 原始请求体字节`。不要重排 JSON 后签名，也不要把密钥发给前端。
+
+成功接收返回 HTTP 200，`{"code":200,"message":"success","data":{"received":true,"paid":true}}`。重复通知返回 `duplicate: true`。验签、字段、订单或金额不符返回 HTTP 4xx，会会可按其重试策略处理。服务端未配置密钥时返回 HTTP 503。
+
+上线前需由会会确认：其服务端是否能按此格式签名并发送通知、支付成功状态与支付流水号字段的正式定义、失败通知及重试/超时策略。小程序支付发起和退款仍需独立对接和验收；仅完成此回调不代表虚拟支付全流程已可用。
