你只需要宣告一個 **Pydantic 模型**，包含你要接收為 **表單欄位** 的欄位，然後將參數宣告為 `Form`：

{* ../../docs_src/request_form_models/tutorial001_an_py310.py hl[9:11,15] *}

**FastAPI** 會從請求中的 **表單資料** 擷取 **各欄位** 的資料，並將這些資料組成你定義的 Pydantic 模型實例。

## 檢視文件 { #check-the-docs }

你可以在 `/docs` 的文件 UI 中驗證：

## Es testen { #check-it }

Gehen Sie zu der interaktiven Dokumentation unter: [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs).

Sie werden etwa Folgendes sehen:

<img src="/img/tutorial/security/image01.png">

/// check | Authorize-Button!

Sie haben bereits einen glänzenden, neuen „Authorize“-Button.

Unutmamanız gereken önemli nokta şudur: `sub` anahtarı, tüm uygulama genelinde benzersiz bir tanımlayıcı olmalı ve string olmalıdır.

## Kontrol Edelim { #check-it }

Server'ı çalıştırın ve docs'a gidin: [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs).

/// check | Authorize butonu!

Artık parıl parıl yeni bir "Authorize" butonunuz var.

O **FastAPI** **extrairá** os dados para **cada campo** dos **parâmetros de consulta** presentes na requisição, e fornecerá o modelo Pydantic que você definiu.

## Verifique a Documentação { #check-the-docs }

Você pode ver os parâmetros de consulta na IU da documentação em `/docs`:
