# SQL (관계형) 데이터베이스

**FastAPI**에서 SQL(관계형) 데이터베이스 사용은 필수가 아닙니다. 여러분이 원하는 **어떤 데이터베이스든** 사용할 수 있습니다.

여기서는 <a href="https://sqlmodel.tiangolo.com/" class="external-link" target="_blank">SQLModel</a>을 사용하는 예제를 살펴보겠습니다.

**SQLModel**은 <a href="https://www.sqlalchemy.org/" class="external-link" target="_blank">SQLAlchemy</a>와 Pydantic을 기반으로 구축되었습니다.SQLModel은 **SQL 데이터베이스**를 사용하는 FastAPI 애플리케이션에 완벽히 어울리도록 **FastAPI**의 제작자가 설계한 도구입니다.

请记住可以 <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">用'X-' 前缀</a>添加专有自定义请求头.

但是如果你想让浏览器中的客户端看到你的自定义请求头, 你需要把它们加到 CORS 配置 ([CORS (Cross-Origin Resource Sharing)](cors.md){.internal-link target=_blank}) 的 `expose_headers` 参数中,在 <a href="https://www.starlette.dev/middleware/#corsmiddleware" class="external-link" target="_blank">Starlette's CORS docs</a>文档中.

## Pydantic-Modelle { #pydantic-models }

<a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> ist eine Python-Bibliothek für die Validierung von Daten.

Sie deklarieren die „Form“ der Daten als Klassen mit Attributen.

Und jedes Attribut hat einen Typ.

    // Generated classes may not adhere to the strict no-warning policy that we apply to handwritten code
    // For example, external JMH plugin generates code that produces compiler warnings

# 请求表单与文件

FastAPI 支持同时使用 `File` 和 `Form` 定义文件和表单字段。

/// info | 说明

接收上传文件或表单数据，要预先安装 <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>。

例如，`pip install python-multipart`。

## 定义 `File` 与 `Form` 参数

创建文件和表单参数的方式与 `Body` 和 `Query` 一样：
