## 安装

```bash
# .npmrc 已配置私有 registry，直接安装
npm install @xuqm/rn-sdk
# 或
yarn add @xuqm/rn-sdk

# 依赖安装（peerDependencies）

## 快速开始

### 1. 初始化（App 入口）

```typescript
import { XuqmSDK } from '@xuqm/rn-sdk'

await XuqmSDK.init({
  appKey: 'ak_your_app_key',
  debug: __DEV__,
})
```

### 2. 用户登录后设置 Token

```typescript
await XuqmSDK.setToken('eyJ...')
// 登出时
await XuqmSDK.setToken(null)
```

Token 持久化存储于 `AsyncStorage`，App 重启后自动恢复。

---

## HTTP 客户端

```typescript
import { http } from '@xuqm/rn-sdk'

// 自动附加 Bearer Token
const data = await http.get<UserInfo>('/api/user/profile')
const result = await http.post<LoginResp>('/api/auth/login', { account, password })
```

---

## IM 模块

### ImClient

```typescript
import { ImClient, MsgType, ChatType } from '@xuqm/rn-sdk'

const im = new ImClient()

im.on('connected', () => console.log('IM 已连接'))
im.on('disconnected', (code, reason) => console.log('断开', code))
im.on('message', (msg) => {
  console.log('新消息', msg.content)
  // msg: ImMessage
})
im.on('revoke', ({ msgId, operatorId }) => {
  console.log('消息被撤回', msgId)
})
im.on('error', (err) => console.error(err))

// 连接
im.connect()

// 发送消息
im.send({
  toId: 'user_002',
  chatType: ChatType.SINGLE,
  msgType: MsgType.TEXT,
  content: 'Hello from RN!',
})

// 撤回
im.revoke('msg-uuid')

// 组件卸载时断开
useEffect(() => {
  im.connect()
  return () => im.disconnect()
}, [])
```

### React Hook 封装示例

```typescript
import { useEffect, useState, useRef } from 'react'
import { ImClient, ImMessage } from '@xuqm/rn-sdk'

export function useIm() {
  const [messages, setMessages] = useState<ImMessage[]>([])
  const [connected, setConnected] = useState(false)
  const imRef = useRef<ImClient | null>(null)

  useEffect(() => {
    const im = new ImClient()
    imRef.current = im
    im.on('connected', () => setConnected(true))
    im.on('disconnected', () => setConnected(false))
    im.on('message', (msg) => setMessages(prev => [...prev, msg]))
    im.connect()
    return () => im.disconnect()
  }, [])

  const send = (params: Parameters<ImClient['send']>[0]) =>
    imRef.current?.send(params)

  return { messages, connected, send }
}
```

### ImMessage 结构

```typescript
interface ImMessage {
  id: string
  fromId: string
  toId: string
  chatType: 'SINGLE' | 'GROUP'
  msgType: MsgType
  content: string
  extra?: string
  revoked: boolean
  createdAt: string
}
```

### 消息类型（MsgType）

```typescript
enum MsgType {
  TEXT = 'TEXT',
  IMAGE = 'IMAGE',
  VIDEO = 'VIDEO',
  AUDIO = 'AUDIO',
  FILE = 'FILE',
  CUSTOM = 'CUSTOM',
  LOCATION = 'LOCATION',
  NOTIFY = 'NOTIFY',
  RICH_TEXT = 'RICH_TEXT',
  CALL_AUDIO = 'CALL_AUDIO',
  CALL_VIDEO = 'CALL_VIDEO',
  FORWARD = 'FORWARD',
}
```

### 自动重连

断线后指数退避重连：3s → 6s → 12s → ... → 最大 30s。调用 `disconnect()` 后停止。

---

## 推送模块

```typescript
import { PushSDK } from '@xuqm/rn-sdk'

// 在获取到设备推送 Token 后调用（如小米、华为推送回调）
await PushSDK.registerToken({
  appId: 'ak_xxx',
  userId: 'user_001',
  vendor: 'XIAOMI',    // HUAWEI / XIAOMI / OPPO / VIVO / HONOR / APNS
  token: 'device_push_token',
})
```

---

## 版本管理模块

### 检查 App 更新

```typescript
import { UpdateSDK } from '@xuqm/rn-sdk'

const result = await UpdateSDK.checkAppUpdate({
  appId: 'ak_xxx',
  platform: 'android',     // 'android' | 'ios'
  currentVersionCode: 10,
})

if (result.needsUpdate) {
  console.log(result.versionName, result.downloadUrl, result.forceUpdate)
}
```

### 检查 RN Bundle 热更新

```typescript
const rnResult = await UpdateSDK.checkRnUpdate({
  appId: 'ak_xxx',
  moduleId: 'main',
  platform: 'android',
  currentVersion: '1.0.0',
})

if (rnResult.needsUpdate && rnResult.info) {
  const { downloadUrl, md5 } = rnResult.info
  // 下载 bundle，校验 md5，调用原生模块热加载
}
```
