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.

/// note | 기술 세부사항

폼의 데이터는 일반적으로 "미디어 유형(media type)" `application/x-www-form-urlencoded`를 사용하여 인코딩합니다.

그러나 폼에 파일이 포함된 경우, `multipart/form-data`로 인코딩합니다. 다음 장에서 파일 처리에 대해 읽을 겁니다.

## 關於「表單欄位」 { #about-form-fields }

HTML 表單（`<form></form>`）向伺服器傳送資料時，通常會使用一種「特殊」的編碼方式，與 JSON 不同。

**FastAPI** 會從正確的位置讀取那些資料，而不是從 JSON。

/// note | 技術細節

表單資料通常會使用「媒體類型」`application/x-www-form-urlencoded` 進行編碼。

但當表單包含檔案時，會使用 `multipart/form-data`。你會在下一章閱讀如何處理檔案。
