* It can do something to that **response** or run any needed code.
* Then it returns the **response**.

/// note | Technical Details

If you have dependencies with `yield`, the exit code will run *after* the middleware.

If there were any background tasks (covered in the [Background Tasks](background-tasks.md) section, you will see it later), they will run *after* all the middleware.

/// info | 정보

`Form`은 `Body`에서 직접 상속되는 클래스입니다.

///

/// tip | 팁

폼 본문을 선언할 때는 `Form`을 명시적으로 사용해야 합니다. 그렇지 않으면 매개변수가 쿼리 매개변수나 본문(JSON) 매개변수로 해석됩니다.

///

## "폼 필드"에 대해 { #about-form-fields }

HTML 폼(`<form></form>`)이 데이터를 서버로 보내는 방식은 일반적으로 해당 데이터에 대해 "특수" 인코딩을 사용하며, 이는 JSON과 다릅니다.

**FastAPI**는 JSON 대신 올바른 위치에서 해당 데이터를 읽습니다.

Deklarieren Sie die erforderlichen **Header-Parameter** in einem **Pydantic-Modell** und dann den Parameter als `Header`:

{* ../../docs_src/header_param_models/tutorial001_an_py310.py hl[9:14,18] *}

**FastAPI** wird die Daten für **jedes Feld** aus den **Headern** des <abbr title="Request – Anfrage: Daten, die der Client zum Server sendet">Request</abbr> extrahieren und Ihnen das von Ihnen definierte Pydantic-Modell geben.
