# Function: sendReadReceiptRequest()

> **sendReadReceiptRequest**(`targetId`, `messageUId`, `channelId?`): `Promise`\<[`RCResult`](../interfaces/RCResult.md)\<`void`\>\>

发送群已读回执请求

## Parameters

### targetId

`string`

目标 ID

### messageUId

`string`

### channelId?

`string`

## Returns

`Promise`\<[`RCResult`](../interfaces/RCResult.md)\<`void`\>\>

## Description

实现群聊中按需获取己方发送消息的阅读状态请求。与群聊已读回执响应接口 [sendReadReceiptResponseV2](sendReadReceiptResponseV2.md) 配套使用。单独调用无法实现群回执能力

## Example

群已读回执请求示例：
```ts
const targetId = 'targetId';
const messageUId = 'BS4O-QEBR-VJM6-9GPP';
const readReceiptRes = await RongIMLib.sendReadReceiptRequest(targetId, messageUId);
console.info('群已读回执请求：', readReceiptRes)
```
