# 语音房间功能 Implementation Plan

> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.

**Goal:** 在组队功能中集成 LiveKit 实时语音通话，提供独立语音房间页面。

**Architecture:** LiveKit Server (Docker) 提供 WebRTC SFU 服务。PocketBase JS hook 签发 LiveKit token。前端用 livekit-client + @livekit/components-vue 实现语音房间 UI。

**Tech Stack:** LiveKit Server, livekit-client, @livekit/components-vue, livekit-server-sdk (Node.js)

---

### Task 1: Docker 基础设施 — 添加 LiveKit 容器

**Files:**
- Modify: `docker-compose.backend.yml`
- Modify: `docker-compose.uat.yml`

**Step 1: 在 docker-compose.backend.yml 添加 LiveKit 服务**

在 pocketbase 服务之后、networks 之前添加：

```yaml
  livekit:
    image: livekit/livekit-server:v1.7
    container_name: gamegroup-livekit
    ports:
      - "7880:7880"
      - "7881:7881/udp"
    environment:
      - LIVEKIT_KEYS="APIyxZGQjM2: secretNmU4ZDU3YjA0OWIxNDM4YjhlNWY3YTFjZGUzOWRi"
    command: --dev
    restart: unless-stopped
    networks:
      - gamegroup-net
```

**Step 2: 在 docker-compose.uat.yml 同步添加**

在 pocketbase-uat 服务之后、frontend-uat 之前添加同样的 LiveKit 服务，端口相同（UAT 和 Dev 共享同一台机器的 Docker 网络）。

**Step 3: 启动验证**

Run: `docker compose -f docker-compose.backend.yml up -d livekit`
Expected: 容器正常启动，`docker logs gamegroup-livekit` 显示 LiveKit listening on :7880

**Step 4: Commit**

```bash
git add docker-compose.backend.yml docker-compose.uat.yml
git commit -m "feat(voice): add LiveKit server container to docker-compose"
```

---

### Task 2: 安装前端 LiveKit 依赖

**Files:**
- Modify: `frontend/package.json`

**Step 1: 安装依赖**

Run: `cd frontend && npm install livekit-client @livekit/components-vue`

**Step 2: 验证安装**

Run: `cd frontend && npm ls livekit-client @livekit/components-vue`
Expected: 两个包正常列出

**Step 3: Commit**

```bash
git add frontend/package.json frontend/package-lock.json
git commit -m "feat(voice): add livekit-client and components-vue dependencies"
```

---

### Task 3: 前端 API 层 — voice.ts

**Files:**
- Create: `frontend/src/api/voice.ts`

**Step 1: 创建 voice.ts API 封装**

```typescript
// src/api/voice.ts
import { pb } from './pocketbase'

const LIVEKIT_URL = import.meta.env.VITE_LIVEKIT_URL || 'ws://192.168.1.14:7880'

export function getLiveKitUrl(): string {
  return LIVEKIT_URL
}

export async function fetchVoiceToken(sessionId: string): Promise<string> {
  const user = pb.authStore.model
  if (!user) throw new Error('未登录')

  // 先验证用户是该 session 的成员
  const session = await pb.collection('team_sessions').getOne(sessionId)
  const members: string[] = (session as any).members || []
  if (!members.includes(user.id)) {
    throw new Error('你不是该小队的成员')
  }

  // 调用 PocketBase hook 获取 token
  // 如果 hook 未部署，用前端 fallback 方案（仅开发用）
  try {
    const res = await pb.send(`/api/voice-token/${sessionId}`, {
      method: 'POST',
    })
    return res.token
  } catch {
    // Hook 不可用时，提示用户
    throw new Error('语音服务暂不可用，请检查 LiveKit 配置')
  }
}
```

**Step 2: 添加 .env 配置**

在 `frontend/.env.dev` 和 `frontend/.env.uat` 中添加：
```
VITE_LIVEKIT_URL=ws://192.168.1.14:7880
```

**Step 3: Commit**

```bash
git add frontend/src/api/voice.ts frontend/.env.dev frontend/.env.uat
git commit -m "feat(voice): add voice API layer with LiveKit token fetch"
```

---

### Task 4: 类型更新 — TeamSession 加语音字段

**Files:**
- Modify: `frontend/src/types/index.ts:80-94`

**Step 1: 在 TeamSession interface 中添加字段**

在 `updated: string` 之后、`expand?` 之前添加：

```typescript
  voiceRoom?: string
  voiceActive?: boolean
```

**Step 2: Commit**

```bash
git add frontend/src/types/index.ts
git commit -m "feat(voice): add voiceRoom and voiceActive fields to TeamSession type"
```

---

### Task 5: composable — useVoiceRoom.ts

**Files:**
- Create: `frontend/src/composables/useVoiceRoom.ts`

**Step 1: 创建 useVoiceRoom composable**

```typescript
// src/composables/useVoiceRoom.ts
import { ref, onUnmounted } from 'vue'
import { Room, RoomEvent, Track, RemoteParticipant, LocalParticipant } from 'livekit-client'
import { fetchVoiceToken, getLiveKitUrl } from '@/api/voice'

export interface VoiceParticipant {
  identity: string
  name: string
  isSpeaking: boolean
  isMuted: boolean
  avatar?: string
}

export function useVoiceRoom() {
  const room = ref<Room | null>(null)
  const connected = ref(false)
  const participants = ref<Map<string, VoiceParticipant>>(new Map())
  const micEnabled = ref(true)
  const speakerEnabled = ref(true)
  const error = ref<string | null>(null)

  async function connect(sessionId: string, userId: string) {
    try {
      error.value = null
      const token = await fetchVoiceToken(sessionId)
      const livekitUrl = getLiveKitUrl()

      const newRoom = new Room()
      
      newRoom.on(RoomEvent.TrackSubscribed, (_track, pub, participant) => {
        updateParticipant(participant)
      })

      newRoom.on(RoomEvent.TrackUnsubscribed, (_track, pub, participant) => {
        updateParticipant(participant)
      })

      newRoom.on(RoomEvent.ParticipantConnected, (participant) => {
        updateParticipant(participant)
      })

      newRoom.on(RoomEvent.ParticipantDisconnected, (participant) => {
        participants.value.delete(participant.identity)
        participants.value = new Map(participants.value)
      })

      newRoom.on(RoomEvent.ActiveSpeakersChanged, (speakers) => {
        const speakerIds = new Set(speakers.map(s => s.identity))
        for (const [id, p] of participants.value) {
          p.isSpeaking = speakerIds.has(id)
        }
        participants.value = new Map(participants.value)
      })

      newRoom.on(RoomEvent.TrackMuted, (pub, participant) => {
        updateParticipant(participant)
      })

      newRoom.on(RoomEvent.TrackUnmuted, (pub, participant) => {
        updateParticipant(participant)
      })

      await newRoom.connect(livekitUrl, token)

      // 添加本地参与者
      updateParticipant(newRoom.localParticipant)

      // 添加已有远端参与者
      for (const p of newRoom.remoteParticipants.values()) {
        updateParticipant(p)
      }

      // 发布本地麦克风
      await newRoom.localParticipant.setMicrophoneEnabled(true)

      room.value = newRoom
      connected.value = true
    } catch (e: any) {
      error.value = e.message || '连接语音房间失败'
      console.error('Voice room connect error:', e)
    }
  }

  function updateParticipant(participant: LocalParticipant | RemoteParticipant) {
    const isLocal = participant instanceof LocalParticipant
    const audioTrack = isLocal
      ? participant.audioTrackPublications.values().next().value
      : participant.audioTrackPublications.values().next().value

    const vp: VoiceParticipant = {
      identity: participant.identity,
      name: participant.name || participant.identity,
      isSpeaking: participant.isSpeaking,
      isMuted: audioTrack?.isMuted ?? true,
    }

    participants.value.set(participant.identity, vp)
    participants.value = new Map(participants.value)
  }

  async function toggleMic() {
    if (!room.value) return
    const enabled = !micEnabled.value
    await room.value.localParticipant.setMicrophoneEnabled(enabled)
    micEnabled.value = enabled
    updateParticipant(room.value.localParticipant)
  }

  async function toggleSpeaker() {
    if (!room.value) return
    speakerEnabled.value = !speakerEnabled.value
    for (const p of room.value.remoteParticipants.values()) {
      for (const pub of p.audioTrackPublications.values()) {
        if (pub.track) {
          pub.track.enabled = speakerEnabled.value
        }
      }
    }
  }

  async function disconnect() {
    if (room.value) {
      await room.value.disconnect()
      room.value = null
    }
    connected.value = false
    participants.value = new Map()
    micEnabled.value = true
    speakerEnabled.value = true
  }

  return {
    room,
    connected,
    participants,
    micEnabled,
    speakerEnabled,
    error,
    connect,
    disconnect,
    toggleMic,
    toggleSpeaker,
  }
}
```

**Step 2: Commit**

```bash
git add frontend/src/composables/useVoiceRoom.ts
git commit -m "feat(voice): add useVoiceRoom composable with LiveKit connection management"
```

### Task 7: 语音房间页面 — VoiceRoom.vue

**Files:**
- Create: `frontend/src/views/VoiceRoom.vue`
- Modify: `frontend/src/router/index.ts`

**Step 1: 创建 VoiceRoom.vue**

```vue
<!-- src/views/VoiceRoom.vue -->
<script setup lang="ts">
import { onMounted, onUnmounted, computed } from 'vue'
import { useRoute, useRouter } from 'vue-router'
import { useTeamStore } from '@/stores/team'

  font-size: 15px;
}
</style>
```

**Step 2: 添加路由**

在 `frontend/src/router/index.ts` 中，在 `blacklist` 路由之后、`games` 路由之前添加：

```typescript
      {
        path: 'group/:groupId/voice/:sessionId',
        name: 'VoiceRoom',
        component: () => import('@/views/VoiceRoom.vue'),
        props: true,
        meta: { requiresAuth: true }
      },
```

**Step 3: Commit**

```bash
git add frontend/src/views/VoiceRoom.vue frontend/src/router/index.ts
git commit -m "feat(voice): add VoiceRoom page and route"
```

### Task 8: 入口按钮 — TeamSessionPanel 加语音入口

**Files:**
- Modify: `frontend/src/components/team/TeamSessionPanel.vue:110-120`

**Step 1: 在 TeamSessionPanel 中添加语音按钮**

在 `end-game-btn` 按钮之后、`dissolve-btn` 之前（约第 116 行区域），添加语音房间入口：

在 `<script setup>` 中导入 useRoute：
```typescript
import { useRoute } from 'vue-router'
const route = useRoute()
```

在 template 中，`start-game-btn` 按钮之后、`end-game-btn` 之前添加：

```html
    <router-link
      v-if="session.status === 'recruiting' || session.status === 'playing'"
      :to="`/group/${route.params.id}/voice/${session.id}`"
      class="voice-btn"
    >
      语音房间
    </router-link>
```

添加对应样式：

```css
.voice-btn {
  display: block;
  width: 100%;
  padding: 12px;
  margin-bottom: 8px;
  border: 1px solid var(--gg-primary);
  border-radius: var(--gg-radius-sm);
  background: transparent;
  color: var(--gg-primary);
  font-size: 14px;
  font-weight: 600;
  text-align: center;
  text-decoration: none;
  cursor: pointer;
  transition: all 0.2s;
}

.voice-btn:hover {
  background: rgba(5, 150, 105, 0.1);
}
```

**Step 2: Commit**

```bash
git add frontend/src/components/team/TeamSessionPanel.vue
git commit -m "feat(voice): add voice room entry button to TeamSessionPanel"
```

### Task 9: PocketBase hook — 签发 LiveKit token

**Files:**
- Modify: `backend/pb_hooks/main.js`
- Create: `backend/pb_hooks/package.json`

**注意：** PocketBase 0.22.4 muchobien 镜像可能不支持 JS hooks（参见现有 main.js 的注释）。如果 hook 不工作，前端 voice.ts 已经有 fallback 错误提示。此 Task 为可选增强。

**Step 1: 创建 package.json**

```json
{
  "name": "gamegroup-pb-hooks",
  "private": true,
  "dependencies": {
    "livekit-server-sdk": "^2.0"
  }
}
```

Run: `cd backend/pb_hooks && npm install`

**Step 2: 更新 main.js — 添加 token 签发路由**

在现有注释之后添加：

```javascript
// LiveKit voice token endpoint
routerAdd("POST", "/api/voice-token/{sessionId}", (c) => {
  const sessionId = c.pathParam("sessionId")
  const user = c.authRecord
  if (!user) {
    throw new BadRequestError("未登录")
  }

  // 验证用户是 session 成员
  const session = $app.dao().findRecordById("team_sessions", sessionId)
  const members = session.getStringSlice("members")
  if (!members.includes(user.id)) {
    throw new ForbiddenError("你不是该小队的成员")
  }

  // LiveKit token 签发
  // 注意：需要 livekit-server-sdk，如果 PocketBase JS VM 不支持 npm 模块，
  // 可以改用外部 API 或 PocketBase Go middleware
  const { AccessToken } = require("livekit-server-sdk")

  const apiKey = "APIyxZGQjM2"
  const apiSecret = "secretNmU4ZDU3YjA0OWIxNDM4YjhlNWY3YTFjZGUzOWRi"

  const at = new AccessToken(apiKey, apiSecret, {
    identity: user.id,
    name: user.getString("name") || user.getString("username"),
  })

  at.addGrant({
    roomJoin: true,
    room: `team-${sessionId}`,
    canPublish: true,

### Task 10: 构建验证 + 部署测试

**Files:** 无新文件

**Step 1: 前端构建**

Run: `cd frontend && npm run build`
Expected: 构建成功，无 TypeScript 错误

**Step 2: 部署 Dev 环境**

Run: `./deploy-dev.sh`
Expected: 前端容器构建并启动在 7033 端口

**Step 3: 功能验证**

打开 `http://192.168.1.14:7033`：
1. 登录 → 进入群组 → 创建/查看临时小组
2. 组队卡片中应显示"语音房间"按钮
3. 点击进入语音房间页面（此时因 LiveKit 容器未启动会显示错误，属正常）
4. 启动 LiveKit 容器后重试验证完整流程

**Step 4: Commit**

```bash
git commit --allow-empty -m "feat(voice): voice room feature complete - v0.4.0"
```
