# requestPermission

> 函数式 API `requestPermission`也可以用来使用相同功能。

### 功能说明

请求权限。对于尚未确定的（`notDetermined`）权限，会向用户显示权限请求；如果权限已经确定，则直接返回已确定的状态。结果始终是 `allowed` 或 `denied`。

### 类型

```ts
requestPermission(permission: { name: PermissionName; access: PermissionAccess }): Promise<Exclude<PermissionStatus, "notDetermined">>;
```

**参数**

```ts
type PermissionName =
  "clipboard" | "contacts" | "photos" | "geolocation" | "camera" | "microphone";

type PermissionAccess = "read" | "write" | "access";
```

**响应**

```ts
type PermissionStatus = "notDetermined" | "denied" | "allowed";
// 请求结果是除 notDetermined 之外的 "allowed" | "denied" 之一。
```

### 示例代码

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

const status = await requestPermission({ name: "camera", access: "access" });

if (status === "allowed") {
  console.log("相机权限已被允许。");
}
```

## 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/quan-xian/requestpermission.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.
