# Review\.request

> 函数式 API `requestReview`也能用它实现相同功能。

### 功能说明

向用户请求迷你应用评价。Toss 应用 Android/iOS `5.253.0` 可在以上版本中使用。

调用前 `Review.request.isSupported()`可以通过它确认是否支持。在不支持的版本中调用时 `UNSUPPORTED_APP_VERSION` 会发生错误。

### 类型

```ts
Review.request(): Promise<void>;
```

**参数**

无。

**响应**

无。

### 错误

错误代码是 catch 到的错误的 `error.code` 值。

| 代码                        | 说明                                                                                                            |
| ------------------------- | ------------------------------------------------------------------------------------------------------------- |
| `UNSUPPORTED_APP_VERSION` | 如果当前运行的 Toss App 版本不支持此功能，则调用后会立即发生。 `Review.request.isSupported()`请先通过它确认，发生时 `error.message`请向用户显示（更新提示文案）。 |

### 示例代码

```js
import { Review } from "@apps-in-toss/web-framework";

try {
  await Review.request();
} catch (error) {
  console.error(error);
}
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://developers-apps-in-toss.toss.im/documentation/api-and-sdk-zh/sdk/domains-api/ping-jia/review.request.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
