## "폼 데이터"란

HTML의 폼들(`<form></form>`)이 서버에 데이터를 전송하는 방식은 대개 데이터에 JSON과는 다른 "특별한" 인코딩을 사용합니다.

**FastAPI**는 JSON 대신 올바른 위치에서 데이터를 읽을 수 있도록 합니다.

/// note | 기술적 세부사항

폼의 데이터는 파일이 포함되지 않은 경우 일반적으로 "미디어 유형" `application/x-www-form-urlencoded` 을 사용해 인코딩 됩니다.

하지만 파일이 포함된 경우, `multipart/form-data`로 인코딩됩니다. `File`을 사용하였다면, **FastAPI**는 본문의 적합한 부분에서 파일을 가져와야 한다는 것을 인지합니다.

型を使用した標準的なPythonを記述します:

```Python
from datetime import date

# Declare a variable as a str
# and get editor support inside the function
def main(user_id: str):

# A Pydantic model
