## 关于 "表单字段"

与 JSON 不同，HTML 表单（`<form></form>`）向服务器发送数据通常使用「特殊」的编码。

**FastAPI** 要确保从正确的位置读取数据，而不是读取 JSON。

!!! note "技术细节"

    表单数据的「媒体类型」编码一般为 `application/x-www-form-urlencoded`。

    但包含文件的表单编码为 `multipart/form-data`。文件处理详见下节。

**FastAPI** will make sure to read that data from the right place instead of JSON.

!!! note "Technical Details"
    Data from forms is normally encoded using the "media type" `application/x-www-form-urlencoded`.

    But when the form includes files, it is encoded as `multipart/form-data`. You'll read about handling files in the next chapter.

    Daten aus Formularen werden normalerweise mit dem <abbr title='Media type – Medientyp, Typ des Mediums'>„media type“</abbr> `application/x-www-form-urlencoded` kodiert.

    Wenn das Formular stattdessen Dateien enthält, werden diese mit `multipart/form-data` kodiert. Im nächsten Kapitel erfahren Sie mehr über die Handhabung von Dateien.

O **FastAPI** fará a leitura desses dados no lugar certo em vez de JSON.

!!! note "Detalhes técnicos"
    Os dados dos formulários são normalmente codificados usando o "tipo de mídia" `application/x-www-form-urlencoded`.

     Mas quando o formulário inclui arquivos, ele é codificado como `multipart/form-data`. Você lerá sobre como lidar com arquivos no próximo capítulo.
