# 新版 VIP 权限策略 Flutter 客户端对接文档 ## 1. VIP 权限策略 ### 1.1 权限来源 - VIP 等级只用于套餐名称、价格、有效期和等级展示。 - Flutter 只使用 `GET /api/v1/vip/me` 返回的 `data.state.effective_benefits` 判断当前用户是否具有某项权益。 - Flutter 不得使用 `VIP等级 >= N`、`unlock_level`、`app_code` 或本地权益表推导权限。 - `/api/v1/vip/packages` 中的 `packages[].benefits` 是该套餐当前配置的完整权益集合，只用于套餐页和升级引导，不能作为用户已拥有权益。 - 写操作最终以对应业务接口的服务端鉴权结果为准。Flutter 的权益判断只用于入口显隐、锁态和交互预判。 ### 1.2 Flutter 权益状态 ```dart class VipEntitlementState { final VipProgramConfig program; final VipIdentity effectiveVip; final String effectiveSource; // paid / trial / none final Map benefitsByCode; final VipUserSettings settings; final int evaluatedAtMs; bool has(String benefitCode) { return program.status == 'active' && effectiveVip.active && benefitsByCode[benefitCode]?.status == 'active'; } bool allowsRoomEntryNotice() { return has('room_entry_notice') && settings.roomEntryNoticeEnabled; } bool allowsOnlineGlobalNotice() { return has('online_global_notice') && settings.onlineGlobalNoticeEnabled; } } ``` `benefitsByCode` 必须由 `state.effective_benefits` 转换。未知 `benefit_code` 保留在状态中但不自动开放功能，不得导致解析失败或页面崩溃。 ### 1.3 权益刷新 | 场景 | Flutter 处理 | |---|---| | 登录成功、切换账号、切换 App | 清空原 VIP 状态，调用 `/vip/me` | | App 冷启动、回到前台 | 调用 `/vip/me` 校准过期、体验卡回落和后台配置变更 | | 进入 VIP 页面 | 并发调用 `/vip/packages` 和 `/vip/me` | | 购买、佩戴体验卡、卸下体验卡成功 | 使用响应中的 `state` 原子替换本地状态 | | 收到 `vip_notice` | 按 `event_id` 去重，再调用 `/vip/me` | | `config_version` 不一致 | 用户权限以 `/vip/me.state` 为准，重新请求 `/vip/packages`，不得合并不同版本的权益数组 | | VIP 到期倒计时结束 | 可更新页面显示，但执行功能前仍以服务端接口结果为准 | ### 1.4 Fami 初始等级权益 下表只用于识别初始配置。Flutter 实际必须渲染 `/vip/packages` 返回的数据。 | 等级 | 本级初始新增权益 | |---|---| | VIP1 | `vip_badge_identity`、`vip_medal`、`avatar_frame`、`vip_title` | | VIP2 | `chat_bubble`、`vip_gift`、`entry_effect`、`visitor_history` | | VIP3 | `voice_wave`、`profile_card`、`custom_room_background`、`room_image_message` | | VIP4 | `animated_avatar`、`animated_room_cover`、`mic_skin`、`room_border`、`vehicle` | | VIP5 | `colored_room_name`、`colored_nickname`、`colored_id`、`gift_tray_skin` | | VIP6 | `hide_profile_data`、`custom_avatar_frame`、`leaderboard_invisible`、`daily_coin_rebate` | | VIP7 | `custom_profile_card`、`anonymous_profile_visit`、`custom_gift` | | VIP8 | `room_entry_notice`、`custom_pretty_id`、`custom_vehicle` | | VIP9 | `anti_kick`、`anti_mute`、`online_global_notice` | ## 2. 通用协议 - API 前缀：`/api/v1`。 - 请求头：`Authorization: Bearer `。 - `app_code`、`user_id` 从登录态解析，Flutter 不传。 - 时间字段统一使用 Unix epoch milliseconds。 - 业务切日使用 UTC，Flutter 仅在展示时转换本地时间。 - 成功响应统一格式： ```json { "code": "OK", "message": "ok", "request_id": "req_xxx", "data": {} } ``` - `request_id` 只用于链路追踪。 - 带 `command_id` 的接口，网络重试必须复用原 `command_id`；新的业务动作必须生成新值。 ## 3.
