+# 36字花移动端接口设计草案（V1）
+
+本文基于 `docs/36字花-数据库与实施计划.md` 与 PRD，先给出移动端可对接的接口清单与字段初设。  
+口径遵循：**全平台单期号、单开奖结果**；渠道仅用于归属、分润与风控，不拆分对局。
+
+**补充（2026-04）**：§**1.5** 描述服务端 **Redis 热点缓存**（`GameHotDataRedis`），**不改变**各接口 URL、参数与响应字段约定，仅供联调与运维对照。
+
+## 1. 设计约定
+
+### 1.1 基础约定
+- 协议：HTTPS + JSON
+- 接口命名规范：`/api/{module}/{action}`，且必须满足正则 `^/api/[a-z]+/[a-z]+[A-Z][a-zA-Z]*$`
+- **请求方法**：所有移动端业务接口（`/api/*`，不含 `/api/v1/authToken`）一律使用 `POST` 调用；查询类接口同时兼容 `GET`（便于浏览器/调试工具直接访问），客户端统一走 `POST`
+  - `POST` 时请求头 `Content-Type: application/json`，参数放在 JSON body
+  - `GET` 兼容模式下，参数走 URL query string
+  - **例外**：公告模块 `/api/notice/noticeList`、`/api/notice/noticeDetail`、`/api/notice/noticeConfirm` 与模拟收银台页 `/api/finance/depositMockPayPage` **仅支持 `GET`**，参数一律走 URL query string
+  - 鉴权类接口 `/api/v1/authToken` 仍为 `GET`
+- 时间：UTC 时间戳（秒） + 服务端时区配置
+- 金额：数字传输（如 `"100.00"`），客户端展示统一保留两位小数（存储仍为 `decimal(18,2)`）
+- 幂等：关键写接口要求 `idempotency_key`
+- 请求头（必带）：
+  - `auth-token`：通过 `GET /api/v1/authToken` 获取的接口鉴权令牌（含义：接口访问的签名鉴权凭证）
+  - `user-token`：用户登录态令牌；需要登录的接口必带
+- 语言请求头：
+  - `lang=zh`：返回中文（默认）
+  - `lang=en`：返回英文
+
+### 1.2 通用响应结构
+```json
+{
+  "code": 1,
+  "message": "ok",
+  "data": {}
+}
+```
+
+- `code=1` 表示成功，非 1 为业务错误
+- `/api/*` 所有接口返回文案支持中英双语：默认中文；请求头 `lang=en` 返回英文，`lang=zh` 返回中文
+- 建议错误码段（按错误性质）：
+  - `1000-1099`：参数错误（字段缺失、类型错误、格式错误、超范围）
+  - `1100-1199`：鉴权错误（未登录、token 失效、权限不足）
+  - `2000-2999`：业务错误（余额不足、对局不存在、订单不存在、公告不存在）
+  - `3000-3099`：流程错误（非法流程/状态不允许，如封盘后下注、重复确认、状态跃迁非法）
+  - `5000-5999`：系统错误（服务异常、依赖超时、未知错误）
+
+- 推荐基础错误码（首版）：
+- `1`：成功
+  - `1001`：参数缺失
+  - `1002`：参数格式错误
+  - `1003`：参数取值非法
+  - `1101`：未登录或登录已过期
+  - `1103`：无权限操作
+  - `2001`：余额不足
+  - `2002`：对局不存在
+  - `2003`：订单不存在
+  - `2004`：公告不存在
+  - `3001`：当前流程不允许该操作
+  - `3002`：已封盘，禁止下注
+  - `3003`：重复请求（幂等冲突）
+  - `5000`：系统繁忙，请稍后重试
+
+### 1.3 鉴权方式
+- **接口鉴权（auth-token）**：所有移动端业务接口请求时必须携带请求头 `auth-token`（由 `/api/v1/authToken` 签发）
+- **用户登录鉴权（user-token）**：需要登录的接口携带请求头 `user-token`；token 失效后调用刷新或重新登录
+
+### 1.4 获取接口鉴权 Token（auth-token）
+- **GET** `/api/v1/authToken`
+- 用途：获取 `auth-token`（所有接口请求头必带）
+
+请求示例：
+`/api/v1/authToken?secret=564d14asdasd113e46542asd6das1a2a&timestamp=1776331077&device_id=1&signature=AD84C49880896DBC16C59C7B122D1FF7`
+
+请求参数：
+- `secret`：string（含义：客户端密钥；服务端从环境变量 `AUTH_TOKEN_SECRET` 校验）
+- `timestamp`：int（含义：请求时间戳；服务端允许与服务器时间误差 ±300 秒）
+- `device_id`：string（含义：设备码）
+- `signature`：string（含义：签名值）
+
+签名算法：
+- 取参与签名的参数（不含 `signature`）：`device_id`、`secret`、`timestamp`
+- 按参数名 **a-z** 排序后拼接为字符串：`key=value&key=value...`
+- 计算：`signature = strtoupper(md5(拼接字符串))`
+
+返回参数：
+- `auth_token`：string（含义：接口鉴权 token；放到请求头 `auth-token`）
+- `expires_in`：int（含义：有效期秒数）
+- `server_time`：int（含义：服务器时间戳，用于校时）
+
+可能错误码：
+- `1001` 参数缺失
+- `1002` 参数格式错误
+- `1103` 密钥无效/签名错误
+- `3001` 时间戳无效
+
+### 1.5 服务端性能与 Redis 热点缓存（实现说明）
+
+> **对客户端无契约变更**：请求路径、参数、响应 JSON 形状与错误码均不因缓存而改变；本节仅说明服务端如何降延迟、读路径与一致性注意点。
+
+**与「框架文件缓存」的区别**
+
+| 配置 | 作用域 |
+|------|--------|
+| `CACHE_DRIVER`（`config/cache.php`，如 `file`） | Think-ORM / `get_sys_config()` 等**系统参数表 `config`** 的模型缓存，落盘在 `runtime/cache`，**不参与**本游戏业务热点路径。 |
+| `GAME_HOT_CACHE_*`（`config/game_hot_cache.php`） | 游戏侧 **`user` / `game_config` / `game_record`** 行级 JSON 缓存，走 **`support\Redis`**（`config/redis.php` 连接），键前缀 `dfw:v1:`。 |
+
+**服务端缓存覆盖（与移动端直接相关的读路径）**
+
+- **用户**：会员鉴权优先读 Redis 中的 `user` 行快照，未命中再查库并回填。**余额、连胜、打码量等变更**落库后，统一经 **`GameHotDataCoordinator::afterUserCommitted($userId)`**：先 **`GameHotDataRedis::userReplaceCacheFromDb`** 与 DB 对齐，再向 Redis 写队列投递幂等刷新任务（见 `GameHotDataWriteQueue` / `GameHotDataQueueConsumer`），用于削峰而非替代同步回源。
+- **游戏配置**：`game_config` 按 `config_key` 缓存。后台直连 `Db` 更新时须 **`GameHotDataCoordinator::afterGameConfigKeyCommitted($key)`**（模型 `GameConfig` 事件与独立表单控制器已接入）；独立保存接口在写入前对同一 `config_key` 使用 **`GameHotDataLock`（`TYPE_GAME_CONFIG`）** 互斥。勿仅删除缓存键而不回源，否则最长不一致窗口为 TTL。
+- **对局**：当前活跃局、按 `id` 的局、最新一条 `game_record` 等；写库后经 **`GameHotDataCoordinator::afterGameRecordCommitted`** 同步刷新相关 Redis 键并入队。开奖/封盘等路径另可按记录 id 使用 **`GameHotDataLock`（`TYPE_GAME_RECORD`）** 串行化。
+
+**环境变量（示例见仓库根目录 `.env-example`）**
+
+- `GAME_HOT_CACHE_ENABLED`：是否启用上述 Redis 热点缓存（`false` 时全程回退数据库）。
+- `GAME_HOT_CACHE_TTL_GAME_CONFIG` / `GAME_HOT_CACHE_TTL_GAME_RECORD` / `GAME_HOT_CACHE_TTL_USER`：各类缓存 TTL（秒）；**以写后同步回源为主**，TTL 仅作兜底。
+- `GAME_HOT_CACHE_ENABLE_WRITE_QUEUE` 及队列长度、消费进程间隔等：控制写库后的**幂等刷新任务**是否入队及背压策略（见 `config/game_hot_cache.php`）。
+
+**一致性提示（联调/测试）**
+
+- 任何绕过协调入口、只改 DB 不调用 **`GameHotDataCoordinator`** 的手工脚本，都可能与 Redis 短期不一致；生产环境应避免。
+- **`POST /api/game/betPlace`** 扣款路径使用与后台钱包加减点相同的 **用户维度 Redis 锁**（`GameHotDataRedis::userAdminMutationLockTry`）及 **`WHERE coin = ?` 条件更新**，与并发派彩/后台调账互斥；失败时返回 **§4.2** 所列中文说明。
+- 客户端仍可按 **§3.2 `dictionaryList` 的 `version`** 做本地缓存；服务端字典另有 Redis 加速，二者可同时存在。
+

+
+**可能错误码（补充）**（其余见文档头部错误码分段；扣款与缓存一致性强相关）：
+
+- `3001`：游戏已暂停（`runtime_enabled=false`，后台「游戏实时对局」关闭运行开关或作废本局后未重新开启；与非法流程类错误同段）
+- `5000`：系统繁忙；或 **用户 Redis 互斥锁**未获取（与后台钱包/并发写同一用户串行，文案与后台一致：「该用户正在被其他管理员操作（钱包/并发保存），请稍后再试」）；或 **`coin` 条件更新**未命中（并发下注/派彩/后台已改余额：「扣款失败：该用户余额已被其他请求修改（如下注、派彩或其他管理员已保存），请刷新后重试」）。
+
+> 说明：一键重复上一注、自动托管开启/停止均由前端控制，客户端在相应时机调用 `/api/game/betPlace` 即可完成，不再提供独立接口。
+
+### 4.3 查询我的下注记录（最近1个月）
+- **POST** `/api/game/betMyOrders`
+
+请求参数：
+- `page`：int（可选，默认 1）

+  - `result_number`：int/null（含义：开奖号码，未开可空）
+  - `win_amount`：string（含义：中奖金额）
+  - `status`：string（含义：订单状态）
+  - `create_time`：int（含义：下注时间）
+- `pagination`：object（`page`、`page_size`、`total`，含义：分页信息）
+
+---
+
+## 5. 钱包与资金模块（wallet/finance）
+
+### 5.1 获取钱包摘要
+- **POST** `/api/wallet/balanceSummary`
+
+返回参数：
+- `coin_balance`：string（含义：可用余额，等同于 `user.coin`）
+- `frozen_balance`：string（含义：冻结余额；当前系统无冻结场景，固定返回 `0.00`）
+- `withdrawable_balance`：string（含义：可提现余额；等同于 `coin_balance`，**单笔实际上限以 `max_withdrawable` 为准**）
+- `max_withdrawable`：string（含义：**当前允许发起的单笔最大提现金额** = min(`coin_balance`, 打码配额余量)；客户端直接用于"最大可提 XXX"提示与金额输入上限校验）
+- `total_deposit_coin`：string（含义：累计充值币额）
+- `total_withdraw_coin`：string（含义：累计提现币额；提现受理时累加）
+- `bet_flow_coin`：string（含义：打码量/流水；开奖结算后按每注 `total_amount` 1:1 累加）
+- `withdraw_flow`：object（含义：打码量 / 提现配额诊断快照，供前端展示说明与上限推导）
+  - `ratio`：string（含义：打码量倍数，来自 `game_config.withdraw_bet_flow_ratio`，默认 `1.00`；`0` 表示"不限打码"）
+  - `net_deposit`：string（含义：净充值 = max(0, 累计充值 - 累计提现)）
+  - `required_bet_flow`：string（含义：按门槛口径所需的打码量 = 净充值 × 倍数，纯展示）
+  - `remaining_bet_flow`：string（含义：按门槛口径还差多少打码量，纯展示；已达标为 `0.00`）
+  - `eligible`：bool（含义：是否满足整体门槛，纯展示，实际放行以 `max_withdrawable` 为准）
+  - `max_withdraw_by_flow`：string/null（含义：仅按打码量折算的单笔可提上限 = max(0, `bet_flow_coin` / `ratio` - `total_withdraw_coin`)；`ratio=0` 不限打码时返回 `null`）
+  - `flow_unlimited`：bool（含义：是否处于"不限打码"状态，`ratio=0` 时为 `true`）
+
+说明（打码量即提现配额模型）：
+- 每笔提现按 `withdraw_coin × ratio` 消耗打码配额；`total_withdraw_coin` 已累积历史消耗。
+- **单笔最大可提现 `max_withdrawable = min(coin_balance, max_withdraw_by_flow)`**；`ratio=0` 时退化为仅受余额约束。
+- 倍数 `ratio` 由后台「游戏配置 → `withdraw_bet_flow_ratio`」维护，修改后对新请求立即生效。
+- 历史累计类字段（`total_deposit_coin` / `total_withdraw_coin` / `bet_flow_coin`）均为累加语义；若后续审核驳回，回冲逻辑由后台审核流程负责。
+
+### 5.2 钱包流水
+- **POST** `/api/wallet/recordList`
+
+请求参数：
+- `page`：int（可选，默认 1）
+- `page_size`：int（可选，默认 20）
+- `type`：string，可选（含义：流水类型筛选，可选值如下；不传表示查询全部）
+  - `deposit`：充值入账（充值订单成功后，金额入账到玩家余额）
+  - `withdraw`：提现出账（提现订单受理/打款后，金额从玩家余额扣除或冻结）
+  - `bet`：下注扣款（提交下注时从玩家余额扣除的投注金额）
+  - `payout`：开奖派彩（中奖后系统将奖金入账到玩家余额）
+  - `adjust`：人工调整（后台管理员加/扣点，对应 `biz_type=admin_credit/admin_deduct`）
+  - `bet_void`：期次作废退款（后台「游戏实时对局」作废本局时，退回待开奖注单本金）
+
+返回参数：
+- `list`：array<object>
+  - `record_id`：int（含义：钱包流水 ID）
+  - `biz_type`：string（含义：业务类型）
+  - `direction`：int（1入2出，含义：资金方向）

+  - `balance_before`：string（含义：变动前余额）
+  - `balance_after`：string（含义：变动后余额）
+  - `ref_type`：string（含义：关联业务单类型）
+  - `ref_id`：string（含义：关联业务单标识）
+  - `create_time`：int（含义：流水时间）
+
+补充约定：
+- 金额字段（`amount`、`balance_before`、`balance_after` 等）客户端显示统一两位小数。
+- 后台管理员加减点会生成 `biz_type=admin_credit/admin_deduct` 的流水记录，备注默认模板：`后台管理员（操作管理员）加点/扣点100（值）`（示例）。
+
+### 5.3 充值档位列表
+- **POST** `/api/finance/depositTierList`
+
+说明：
+- 由后台「配置管理 → 充值档位」维护，存放在 `game_config.deposit_tier`（JSON 数组）。
+- 后台表单中的「支付货币」下拉来源于 `game_config.finance_cashier.currencies`（不再前端硬编码）。
+- 初始化/重建档位时按当前 `finance_cashier` 货币集合生成：**每种货币 6 条档位**（运营可再编辑）。
+- 仅返回启用状态（`status=1`）的档位，按 `sort` 升序；玩家仅能从中选择。
+- 档位仅描述"充值规格"，不再包含收款账户；具体收款由第三方支付网关返回的 `pay_url` 引导。
+- **多语言**：后台保存 `title`（中文名）、`title_en`（英文名）、`desc`（中文描述）、`desc_en`（英文描述）。接口返回的 `title` / `desc` 会根据请求头 `lang` 自动适配：
+  - `lang=zh`（默认）：返回 `title` / `desc`，若为空则回退到英文
+  - `lang=en`：返回 `title_en` / `desc_en`，若为空则回退到中文
+  - 移动端客户端仅看到单一 `title` / `desc`，无需自行判断语言

+    - 每项：`code`（string，渠道代码，小写，与创建订单时传入的 `channel_code` 一致）、`name`（展示名）、`sort`（排序）
+
+### 5.3A 获取充值/提现配置
+- **POST** `/api/finance/depositWithdrawConfig`
+- 兼容旧接口：`POST /api/finance/cashierConfig`（返回结构一致，建议客户端统一切到 `depositWithdrawConfig`）
+

+
+返回参数：
+- `platform_coin_label`：string（平台币名称，按 `lang` 适配）
+- `currencies`：array
+  - `code`：string（货币代码）
+  - `label`：string（货币展示名，按 `lang` 适配）

+### 5.4 创建充值订单
+- **POST** `/api/finance/depositCreate`
+- `Content-Type: application/json`（推荐）、`application/x-www-form-urlencoded` 或 **`multipart/form-data`**（如 Apifox 的 form-data）；字段名与下表一致即可，服务端通过统一参数名读取，**不限制**为某一种 body 类型。
+
+说明（与真实「创建订单 → 调起三方 → 异步回调」一致）：
+- **创建单**：`depositCreate` 仅写入 **待支付** 订单（`status=pending`），**不在此请求内入账**。返回体中 `paid=false`，`pay_url` 为 **模拟第三方收银台** 完整 URL（HMAC 防篡改，见下 §5.4.1）。
+- **客户端**：在 WebView/系统浏览器中打开 `pay_url`；用户完成支付后（模拟页为「确认支付」按钮），由服务端 `depositMockNotify` 验签后调用 `DepositSettlement::settle` 入账，并推送 `wallet.changed`；客户端可轮询 `depositDetail` 或依赖推送更新余额。
+- **未来接入真实第三方支付**：将 `pay_url` 与回调 URL 替换为真网关，入账仍**仅**在回调/验签成功路径中调用 `DepositSettlement::settle`（与当前模拟回调一致）。
+- 档位与渠道取自 `depositTierList`：创建订单时须选择返回 `channels` 中某一渠道的 `code` 作为 `channel_code` 传入；服务端会校验档位存在、启用且渠道已启用。
+- **HMAC 密钥**：模拟链路与签名校验使用环境变量 **`DEPOSIT_MOCK_HMAC_KEY`**（或 `config('app.deposit_mock_hmac_key')`）；生产环境务必配置，与代码中默认值区分。
+- **并发上限**：同一用户最多同时存在 **3 笔待支付充值单**（`status=0`）；超过后创建接口返回 `code=2005`。
+- **超时失效**：充值单创建后 **60 秒内未支付**将自动置为失败（`status=failed`），并在订单备注记录失败原因（`[timeout] unpaid over 60s`）。
+- **定时任务兜底**：服务端进程 `depositOrderExpireTicker` 每 **10 秒**主动扫描超时待支付单，保证即使用户不访问任何充值接口也会准时失效。
+
+请求参数（**三者缺一不可**，任一为空或空白即 `code=1001` 参数缺失）：
+- `tier_id`：string，必填（含义：玩家选择的充值档位 ID，取自 `depositTierList` 的 `id`；也可用同义字段名 `tier_key`）
+- `channel_code`：string，必填（含义：支付渠道代码，**小写**；须与所选档位在 `depositTierList` 返回的 `channels[].code` 之一一致，例如默认内置渠道常为 `directpay`）
+- `idempotency_key`：string，必填，≤64（含义：客户端生成的唯一键，短时间内同 `idempotency_key` 不会重复下单；建议 UUID。**调试工具中若使用变量，请确保解析后非空**）
+
+> **常见 1001 原因**：只传了 `tier_id` + `idempotency_key`，**漏传 `channel_code`**。请先调 `depositTierList`，用对应档位下 `channels` 中某项的 `code` 作为 `channel_code`。
+
+返回参数：
+- `order_no`：string（含义：充值订单号）
+- `amount`：string（2 位小数，含义：玩家本次支付的充值金额，与所选档位 `amount` 一致）
+- `bonus_amount`：string（2 位小数，含义：本次赠送金额，与所选档位 `bonus_amount` 一致，无赠送为 `0.00`）
+- `total_amount`：string（2 位小数，含义：实际入账总额 = amount + bonus_amount）
+- `pay_channel`：string（含义：支付通道标识，与请求中选择的 `channel_code` 一致，落库在订单上）
+- `paid`：bool（含义：当前单据是否已到账；`true` 表示钱包已入账、`status=paid`；`false` 表示待玩家在第三方支付页面完成支付）
+- `pay_url`：string（含义：第三方支付收银台地址；**`paid=false`（待支付）** 时返回**完整 URL**（如 `https://你的域名/api/finance/depositMockPayPage?order_no=...&sign=...`）；`paid=true` 时为空串）
+- `status`：string（`pending`/`paid`/`failed`，含义：本接口创建成功时为 `pending`，入账完成后为 `paid`）
+- `create_time`：int（含义：订单创建时间，秒级时间戳）
+- `pay_time`：int（含义：订单到账时间，未到账为 0）
+
+#### 5.4.1 模拟第三方：收银台页与「异步通知」回调（开发/无真网关时使用）
+
+- **GET** `/api/finance/depositMockPayPage`  
+  - **Query**：`order_no`（与 `depositCreate` 返回一致）、`sign`（HMAC，与 `pay_url` 中一致；**不要自行拼接，须完整使用 `depositCreate` 返回的 `pay_url` 或同接口再次查询到的地址**）  
+  - 无需 `auth-token` / `user-token`（外跳浏览器使用）。  
+  - 返回：HTML 页面，用户点击 **「确认支付（模拟成功）」** 即提交到下方 `depositMockNotify`。
+
+- **POST** `/api/finance/depositMockNotify`  
+  - **Body**（`application/x-www-form-urlencoded` 或 JSON 均可，字段名一致即可）：`order_no`、`sign`（与上页/支付链接一致）  
+  - 无需 `user-token`；`auth-token` 可选（当前实现不校验）。  
+  - 验签成功后：对 `status=0` 的订单执行入账（`DepositSettlement::settle`，`source=third_party` 语义），并推送 `wallet.changed`。已入账订单**幂等**再调返回当前订单信息。  
+  - 成功响应：与 `depositCreate` 成功体相同结构（`code=1` + `data` 为统一充值订单结构）。
+
+错误码约定：
+- `1001`：缺少必填参数（`tier_id`（或 `tier_key`）、`channel_code`、`idempotency_key` 任一未传或为空字符串）
+- `1002`：`idempotency_key` 过长，或与其他玩家的订单冲突
+- `1003`：模拟回调/链接参数非法（如 `sign` 与 `order_no` 不匹配）——`depositMockNotify` 与无效支付链接
+- `2000`：订单落库或入账失败（事务回滚后返回原始错误描述）
+- `2003`：所选 `tier_id` 不存在、已停用或不在启用列表中
+- `2004`：`channel_code` 未配置或已禁用
+- `2005`：待支付充值单超过上限（`data.max_pending`、`data.pending_count`、`data.expire_seconds`）

+用于我的充值记录页的分页列表；列表含订单状态，到账时间/支付通道等完整字段请再调用 `/api/finance/depositDetail` 获取。
+
+请求参数：
+- `page`：int，选填，默认 `1`（含义：页码，从 1 开始）
+- `page_size`：int，选填，默认 `20`，最大 `100`（含义：每页数量，超出范围回退为 `20`）
+
+返回参数：
+- `list`：array（含义：充值订单列表，按 `id desc` 排序）
+  - `order_no`：string（含义：充值订单号）
+  - `amount`：string（2 位小数，含义：本单充值金额）

+  - `page`：int（含义：当前页码）
+  - `page_size`：int（含义：每页数量）
+  - `total`：int（含义：总记录数）
+
+### 5.7 提现申请
+- **POST** `/api/finance/withdrawCreate`
+
+请求参数：
+- `withdraw_coin`：string（含义：申请提现金额，必须 > 0）
+- `receive_account`：string（含义：收款账号）
+- `receive_type`：string（`bank`/`ewallet`/`crypto`，含义：收款类型）
+- `idempotency_key`：string（含义：防重复提交提现）
+
+返回参数：
+- `order_no`：string（含义：提现订单号）
+- `status`：string（`pending_review`/`processing`，含义：提现状态）
+- `fee_coin`：string（含义：手续费）
+- `actual_arrival_coin`：string（含义：实到账金额）
+- `risk_review_required`：bool（含义：是否命中人工审核）
+
+校验顺序（任一失败即返回对应错误码，不再创建订单）：
+1. 参数完整性与金额合法性（`code=1001`；金额必须为数值且 > 0）
+2. **待审核订单数限制**：同一用户 `status=0`（待审核）的 `withdraw_order` 不得超过 3 笔，否则 `code=2004 Too many pending withdraw orders`，`data` 中回传：
+   - `max_pending`：上限值（当前为 `3`）
+   - `pending_count`：当前待审核订单数
+3. `coin_balance >= withdraw_coin`，否则 `code=2001 Insufficient balance`
+4. **单笔上限校验**：`withdraw_coin <= max_withdrawable`，否则 `code=2002 Withdraw exceeds available bet flow`，`data` 中回传：
+   - `max_withdrawable`：**当前允许的单笔最大提现金额**（= `min(coin_balance, max_withdraw_by_flow)`，前端据此提示"最大可提现金额为 XXX"）
+   - `coin_balance`、`bet_flow_coin`、`total_withdraw_coin`、`ratio`
+   - `max_withdraw_by_flow`：仅按打码量折算的上限（= `max(0, bet_flow_coin / ratio - total_withdraw_coin)`）；`ratio=0` 时为 `null`
+5. 以上全通过后在同一事务内：
+   - `withdraw_order` 写入：`amount` / `fee`（默认 0.5%） / `actual_amount = amount - fee` / `status=0`（待审核） / `channel_id` 取自用户归属渠道快照。
+   - `user` 表原子更新：`coin -= withdraw_coin` 且 `total_withdraw_coin += withdraw_coin`（WHERE `coin >= withdraw_coin` 防止并发超额扣减）。
+   - `user_wallet_record` 写入 `biz_type=withdraw`、`direction=2`、`amount=withdraw_coin`、`ref_type=withdraw_order`、`idempotency_key=wd_apply_{order_no}`，代表"冻结"动作。
+
+说明（打码量即提现配额模型）：
+- 单笔最大可提现 `max_withdrawable = min(coin_balance, max_withdraw_by_flow)`；每笔提现按 `withdraw_coin × ratio` 消耗打码配额，已消耗部分累积在 `total_withdraw_coin`。
+- `ratio = 0` 时视为"不限打码"，单笔上限仅受 `coin_balance` 约束。
+- 采用"申请即冻结"语义：提现在移动端提交后立即从 `user.coin` 中扣减并写出金流水；后台审核 **拒绝** 时由管理端在同一事务中回冲余额、`total_withdraw_coin` 与流水，不出现"等待审核期间用户还能把这笔钱再下注"的漏洞。
+- 后台审核 **通过** 时不再额外触碰余额；若管理员调整了 `amount` 或 `fee`，按新旧差额再生成一条 `withdraw` / `withdraw_refund` 流水以保持账务平衡，并同步修正 `total_withdraw_coin`。
+- `withdraw_bet_flow_ratio` 由后台「游戏配置」维护，默认 `1.00`，修改后对新请求立即生效。

+## 7. 推送模块（webman/push）
+
+> 用于移动端实时监听对局状态、开奖结果、余额变更与强公告事件。  
+> 协议与客户端行为对齐 [Pusher Channels](https://pusher.com/docs/channels/library_auth_reference/pusher-websockets-protocol/)（webman/push 内置兼容客户端 `push.js`）。  
+> 参考：[webman/push 官方文档](https://www.workerman.net/doc/webman/plugin/push.html)
+
+### 7.1 频道命名与职责（优化版）
+
+| 频道名 | 类型 | 订阅方 | 典型事件 |
+|--------|------|--------|----------|
+| `private-user-{user.uuid}` | 私有（`private-` 前缀） | 当前登录用户；`{user.uuid}` 与登录态/档案中的 **10 位 `uuid`** 一致 | `bet.accepted`、`wallet.changed`、`withdraw.review_required`、定向 `notice.popout` 等 |
+| `public-game-period` | 公共 | 所有在线客户端 | `period.tick`、`period.locked`、`period.opened` |
+| `public-operation-notice` | 公共 | 所有在线客户端 | 全站/渠道级 `notice.popout`（与私有公告二选一或并存，由实现约定） |
+
+约定说明：
+
+- **用户私有频道一律使用对外标识 `uuid`，不使用数据库主键 `user_id`**，避免与后台、日志、多端展示口径不一致，并降低枚举内网 ID 的风险。
+- 名称以 `private-` 开头的频道必须通过 **私有频道鉴权**（见 7.2）成功后才能收到服务端推送。
+- `public-*` 可直接订阅，无需鉴权 HTTP 步骤。
+
+### 7.2 连接地址与鉴权流程
+
+**WebSocket 连接 URL（与官方 `push.js` 一致）**
+
+- 形如：`{websocket_base}/app/{app_key}`
+- 示例（本地默认配置见 `config/plugin/webman/push/app.php`）：`ws://127.0.0.1:3131/app/{app_key}`
+- 生产环境请改为 `wss://` 与对外域名，并与网关/证书一致。
+
+**连接建立后的协议步骤（简述）**
+
+1. 客户端建立 WebSocket，服务端下发 `pusher:connection_established`，payload 内含 **`socket_id`**（后续鉴权必填）。
+2. 订阅 **公共** 频道：发送 `pusher:subscribe`，`data` 仅含 `channel` 名即可。
+3. 订阅 **私有** 频道：
+   - 客户端向 **鉴权接口** 发起 `POST`（`Content-Type: application/x-www-form-urlencoded`），表单字段：`channel_name`、`socket_id`。
+   - 默认鉴权路径为 **`/plugin/webman/push/auth`**（与 `config/plugin/webman/push/app.php` 中 `auth` 一致，可随部署调整）。
+   - 服务端校验「当前登录用户是否允许订阅该 `channel_name`」——对 `private-user-{uuid}` 应校验 **`uuid` 与当前用户一致**，否则返回 `403`。
+   - 鉴权成功返回的 JSON 由 `push.js` 原样作为 `pusher:subscribe` 的 `data` 发送（含 `auth` 等字段）。
+
+**与移动端登录态的关系**
+
+- 客户端在调用鉴权接口时，除 `channel_name` / `socket_id` 外，需携带与 REST API 一致的 **`user-token`（及业务所需的 `auth-token`）**，由服务端解析用户身份后再比对 `private-user-{uuid}`。
+- **不建议**依赖浏览器 Cookie Session 作为唯一依据（H5 外还有 App 内嵌、小程序等）；若仅沿用框架示例中的 Session，需在落地实现中改为 **无状态 token 校验**。
+
+### 7.3 事件定义（初设）
+
+| 事件名 | 建议频道 | 说明 |
+|--------|----------|------|
+| `period.tick` | `public-game-period` | 倒计时广播 |
+| `period.locked` | `public-game-period` | 封盘 |
+| `period.opened` | `public-game-period` | 开奖完成（中奖号码） |
+| `bet.accepted` | `private-user-{uuid}` | 下注成功回执 |
+| `bet.settled` | `private-user-{uuid}` | **每期每用户一条**：该局开奖对该用户全部注单的汇总（`total_win_amount`、`order_count`、`hit_order_count`、`result_number`、`balance_after`；不再按单笔注单重复推送） |
+| `wallet.changed` | `private-user-{uuid}` | 余额变化（中奖派彩入账等；`reason=payout` 等） |
+| `notice.popout` | `public-operation-notice` 或 `private-user-{uuid}` | 强公告（按业务选择广播或定向） |
+| `withdraw.review_required` | `private-user-{uuid}` | 提现进入审核 |
+
+### 7.4 消息形态（客户端解析）
+
+连接上收到的单帧一般为 JSON，常见两类：
+
+- 协议类：`event` 为 `pusher:connection_established`、`pusher_internal:subscription_succeeded` 等。
+- 业务类：`event` 为业务事件名，`channel` 为频道名，`data` 为负载（可能为字符串化的 JSON，客户端需 `JSON.parse` 一次）。
+
+业务负载示例（与初设一致，字段以实际实现为准）：
+
+```json
+{
+  "event": "period.opened",
+  "channel": "public-game-period",
+  "data": {
+    "period_no": "20260416001",
+    "result_number": 18,
+    "open_time": 1776326400
+  }
+}
+```
+
+### 7.5 降级与一致性
+
+- 推送仅作 **体验增强**：断线、弱网时客户端仍应以 **HTTP 轮询/用户主动刷新**（如 `/api/game/periodCurrent`、`/api/wallet/balanceSummary`）为准。
+- 同一业务状态以 **服务端落库与接口查询** 为最终一致；推送到达顺序不保证与业务因果严格一致，需客户端幂等与去重（可带 `period_no` / `order_no` / 时间戳）。
+
+### 7.6 使用 Apipost 调试 WebSocket 与私有频道
+
+Apipost（v7+）支持 **WebSocket**：新建请求 → 选择 **WebSocket** → 类型选 **Raw**。私有频道遵循「先拿 `socket_id` → 再 HTTP 鉴权 → 再发 `pusher:subscribe`」，与 `vendor/webman/push/src/push.js` 行为一致。
+
+**A. 仅调试公共频道（如 `public-game-period`）**
+
+1. 启动 webman 与 push 进程，确认 `config/plugin/webman/push/app.php` 中 `websocket`、`app_key`。
+2. 在 Apipost 中 WebSocket URL 填：`ws://127.0.0.1:3131/app/{app_key}`（将 `{app_key}` 换成配置中的真实值）。
+3. 点击连接，在消息面板应收到一帧 `pusher:connection_established`，从中取出 `socket_id`（公共订阅可不依赖后续步骤，但便于对照协议）。
+4. 在发送框填入一行 JSON（勿带代码块标记）并发送：
+   `{"event":"pusher:subscribe","data":{"channel":"public-game-period"}}`
+5. 成功时随后会收到 `pusher_internal:subscription_succeeded`；之后服务端向该频道 `trigger` 的事件会出现在消息列表中。
+
+**B. 调试用户私有频道 `private-user-{uuid}`**
+
+1. 同上先连接，从首帧解析出 **`socket_id`**。
+2. 新建 **HTTP** 请求：`POST http://{你的HTTP入口}/plugin/webman/push/auth`  
+   - Header：`Content-Type: application/x-www-form-urlencoded`  
+   - Body（x-www-form-urlencoded）：`channel_name=private-user-{替换为真实uuid}&socket_id={上一步的socket_id}`  
+   - 若鉴权已接入 `user-token`，请在 Header 中一并带上与移动端一致的 **`user-token`**（及 `auth-token` 等），否则会得到 `403` 或无效签名。
+3. 将接口返回的 **JSON 正文**（整段）作为 `pusher:subscribe` 的 `data`：在 Apipost WebSocket 发送  
+   `{"event":"pusher:subscribe","data": <上一步响应 JSON 对象>}`  
+   注意：`push.js` 会把鉴权返回与 `channel` 字段合并后再发送；若手搓 JSON，需保证与官方协议一致（含 `auth` 字段）。
+4. 订阅成功后即可在消息面板等待该私有频道上的业务事件。
+
+**说明**：若仅做协议连通性验证，可暂时使用服务端对鉴权接口的占位实现；**上线前**必须落实「`channel_name` 与当前用户 `uuid` 匹配」校验，避免越权订阅。
+
+---
+
+## 8. 移动端完整调用流程
+
+## 8.1 首次进入游戏
+1. `GET /api/v1/authToken?secret=xxx&timestamp=xxx&device_id=xxx&signature=xxx` 获取 `auth-token`
+2. `POST /api/user/login` 登录（请求头带 `auth-token`）
+3. `POST /api/game/lobbyInit` 拉首页初始化（请求头带 `auth-token`）
+3. 建立 webman/push 连接并订阅：
+   - `public-game-period`
+   - `private-user-{user.uuid}`（`uuid` 取自登录/档案接口，与 7.1 一致）
+4. 收到 `period.tick` 实时刷新倒计时
+5. 用户下注调用 `POST /api/game/betPlace`
+6. 监听 `bet.accepted` + `wallet.changed` 更新下注结果和余额
+7. 监听 `period.opened` 渲染开奖动画并刷新开奖记录
+
+## 8.2 充值到下注到提现闭环
+1. 拉取档位：`POST /api/finance/depositTierList`（玩家选择一档，并记下该档 `channels[].code`）
+2. 创建订单：`POST /api/finance/depositCreate`（`tier_id` + `channel_code` + `idempotency_key`，三者为必填；可用 JSON / form-data / x-www-form-urlencoded）
+   - 返回 `paid=false`、`status=pending`、**非空 `pay_url`**：客户端在 WebView/浏览器中打开 `pay_url`（`GET /api/finance/depositMockPayPage`）；用户在模拟页点击确认后，由 `POST /api/finance/depositMockNotify` 完成入账，或轮询 `depositDetail` / 等 `wallet.changed` 再刷新余额
+   - 未来接真实第三方：将 `pay_url` 换为真网关，入账仅在支付平台 **异步通知** 中调用 `DepositSettlement::settle`（与当前 `depositMockNotify` 路径一致）
+3. 客户端可选轮询 `POST /api/finance/depositDetail` 兜底确认状态；入账成功后会收到 `wallet.changed`
+4. 下注：`POST /api/game/betPlace`
+5. 派彩后收到 `wallet.changed`
+6. 查询流水：`POST /api/wallet/recordList`
+7. 提现：`POST /api/finance/withdrawCreate`（即时冻结 `user.coin` 与写出 `withdraw` 流水） -> `POST /api/finance/withdrawDetail`
+
+## 8.3 公告强触达流程
+1. 客户端监听 `notice.popout` 
+2. 拉取详情 `GET /api/notice/noticeDetail`
+3. 用户勾选确认 `GET /api/notice/noticeConfirm?notice_id=...`
+4. 未确认前可由前端阻断下注入口
+

+
+## 9. 游戏时序流程图（接口 + 推送）

+  L --> D
+```
+

+
+## 10. 后台渠道分红比例配置（管理端补充）
+
+> 本节为管理后台 `/admin/channel`「分配比例」弹窗补充口径，用于便于管理员按角色层级设置二次分红比例。
+
+### 10.1 角色组展示规则
+
+- 表格列顺序调整为：`角色组层级` -> `负责人` -> `状态` -> `分配比例(%)`
+- `角色组层级` 在 `负责人` 前展示，降低识别与分配成本
+- 层级路径使用 `/` 拼接，如：`顶级组 / 运营组 / 一组`
+- 同一负责人若存在多个角色组，按多标签展示多条路径
+- 无角色组时显示 `-`
+
+### 10.2 接口：读取渠道管理员分配配置
+
+- **GET** `/admin/channel/channelAdminShareList?id={channel_id}`
+
+返回参数（`data.list[]`）新增：
+- `group_paths`：array<string>（负责人所属角色组层级路径列表）
+- `group_paths_text`：string（层级路径拼接文本，`|` 分隔，用于兼容纯文本场景）
+
+返回示例（节选）：
+```json
+{
+  "code": 1,
+  "message": "ok",
+  "data": {
+    "channel_id": 1,
+    "channel_name": "渠道A",
+    "list": [
+      {
+        "admin_id": 12,
+        "username": "zhuguan1",
+        "group_paths": ["顶级组 / 运营组 / A组"],
+        "group_paths_text": "顶级组 / 运营组 / A组",
+        "status": 1,
+        "share_rate": "30.00"
+      }
+    ]
+  }
+}
+```
+
+### 10.3 保存约束（沿用现有）
+
+- **POST** `/admin/channel/saveChannelAdminShare`
+- 仅 `status=1` 的行参与占比汇总
+- 启用项分配比例总和必须严格等于 `100.00`
+
+---
+
+## 11. 需要你确认的实现口径（进入接口开发前）
+
+1. **登录方式**：仅账号密码，还是要短信/邮箱验证码？
+2. **提现收款类型**：首版只做银行卡，还是同时支持电子钱包/加密地址？
+3. **自动托管**：是否首期上线；若不上线可先隐藏 `auto-bet` 接口。
+4. **push事件最小集**：是否先只上 `period.tick`、`period.opened`、`wallet.changed` 三类。
+5. **错误码规范**：是否已有公司统一错误码表；若有需对齐替换本草案码段。
+
+确认后可进入下一步：按该文档落地 controller + validate + service + 路由。
