# Storage.getItems

### 기능 설명

모바일 앱의 로컬 저장소에서 여러 문자열 값을 한 번에 가져와요. 앱이 종료되었다가 다시 시작해도 데이터가 유지돼요. 저장되지 않은 키도 결과에 포함되며 값은 `null`이에요.

토스앱 Android/iOS `5.270.0` 이상에서 사용할 수 있어요. 호출 전에 `Storage.getItems.isSupported()`로 지원 여부를 확인할 수 있어요. 미지원 버전에서 호출하면 `UNSUPPORTED_APP_VERSION` 에러가 발생해요.

### 타입

```ts
Storage.getItems(keys: string[]): Promise<Record<string, string | null>>;
```

**Params**

```ts
type Keys = string[];
```

가져올 저장소 키 목록이에요.

**Response**

```ts
type GetItemsResult = Record<string, string | null>;
```

요청한 각 키와 저장된 값을 객체로 반환해요. 저장되지 않은 키의 값은 `null`이에요.

### 에러

| 코드                        | 설명                                                                                                                     |
| ------------------------- | ---------------------------------------------------------------------------------------------------------------------- |
| `UNSUPPORTED_APP_VERSION` | 실행 중인 토스앱 버전이 이 기능을 지원하지 않으면 호출 즉시 발생해요. `Storage.getItems.isSupported()`로 사전 확인하고, 발생 시 `error.message`를 사용자에게 보여주세요. |

### 예시 코드

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

if (Storage.getItems.isSupported()) {
  const items = await Storage.getItems(["theme", "language"]);
  console.log(items.theme);
  console.log(items.language);
}
```

## 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/sdk/domains-api/storage/storage.getitems.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.
