但這樣每次執行 `fastapi` 指令時都要記得傳入正確路徑。

此外，其他工具可能找不到它，例如 [VS Code 擴充套件](../editor-support.md) 或 [FastAPI Cloud](https://fastapicloud.com)，因此建議在 `pyproject.toml` 中使用 `entrypoint`。

### 部署你的應用程式（可選） { #deploy-your-app-optional }

你可以選擇將你的 FastAPI 應用程式部署到 [FastAPI Cloud](https://fastapicloud.com)，如果還沒有，去加入候補名單吧。🚀

如果你已經有 **FastAPI Cloud** 帳號（我們已從候補名單邀請你 😉），你可以用一個指令部署你的應用程式。

部署之前，先確保你已登入：

<div class="termy">

* (Starlette 덕분에) 많은 추가 기능:
    * **웹 소켓**
    * HTTPX 및 `pytest`에 기반한 극히 쉬운 테스트
    * **CORS**
    * **쿠키 세션**
    * ...기타 등등.

### 앱 배포하기(선택 사항) { #deploy-your-app-optional }

선택적으로 FastAPI 앱을 [FastAPI Cloud](https://fastapicloud.com)에 배포할 수 있습니다. 아직이라면 대기자 명단에 등록해 보세요. 🚀

이미 **FastAPI Cloud** 계정이 있다면(대기자 명단에서 초대해 드렸습니다 😉), 한 번의 명령으로 애플리케이션을 배포할 수 있습니다.

<div class="termy">

    /** ISO datetime format pattern with milliseconds and UTC timezone. */
    public static final String ISO_DATETIME_FORMAT = "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'";

    /** Date optional time format identifier. */
    public static final String DATE_OPTIONAL_TIME = "date_optional_time";

### Technical details about the JWT "subject" `sub` { #technical-details-about-the-jwt-subject-sub }

The JWT specification says that there's a key `sub`, with the subject of the token.

It's optional to use it, but that's where you would put the user's identification, so we are using it here.

JWT might be used for other things apart from identifying a user and allowing them to perform operations directly on your API.

### Разверните приложение (необязательно) { #deploy-your-app-optional }

При желании вы можете развернуть своё приложение FastAPI в [FastAPI Cloud](https://fastapicloud.com), перейдите и присоединитесь к списку ожидания, если ещё не сделали этого. 🚀
