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。

若想進一步了解這些編碼與表單欄位，請參考 [<abbr title="Mozilla Developer Network - Mozilla 開發者網路">MDN</abbr> web docs 的 `POST`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/POST)。

/// warning

你可以在一個 *路徑操作（path operation）* 中宣告多個 `Form` 參數，但不能同時再宣告期望以 JSON 接收的 `Body` 欄位，因為該請求的本文會使用 `application/x-www-form-urlencoded` 編碼，而不是 `application/json`。
