## Chamar `uvicorn` { #call-uvicorn }

Em sua aplicação FastAPI, importe e execute `uvicorn` diretamente:

{* ../../docs_src/debugging/tutorial001_py310.py hl[1,15] *}

### Sobre `__name__ == "__main__"` { #about-name-main }

O objetivo principal de `__name__ == "__main__"` é ter algum código que seja executado quando seu arquivo for chamado com:

<div class="termy">

```console

# Recipes

We've written some recipes that demonstrate how to solve common problems with OkHttp. Read through them to learn about how everything works together. Cut-and-paste these examples freely; that's what they're for.

### Synchronous Get ([.kt][SynchronousGetKotlin], [.java][SynchronousGetJava])

   * lists are sublist views of the original list, produced on demand using {@link List#subList(int,
   * int)}, and are subject to all the usual caveats about modification as explained in that API.
   *
   * @param list the list to return consecutive sublists of
   * @param size the desired size of each sublist (the last may be smaller)
   * @return a list of consecutive sublists

#### Über `**user_dict` { #about-user-dict }

`UserInDB(**user_dict)` bedeutet:

*Übergib die Schlüssel und Werte des `user_dict` direkt als Schlüssel-Wert-Argumente, äquivalent zu:*

```Python
UserInDB(

{* ../../docs_src/security/tutorial003_an_py310.py hl[82:85] *}

#### Sobre `**user_dict` { #about-user-dict }

`UserInDB(**user_dict)` significa:

*Pasa las claves y valores de `user_dict` directamente como argumentos clave-valor, equivalente a:*

```Python
UserInDB(

Para declarar bodies de formularios, necesitas usar `Form` explícitamente, porque sin él, los parámetros se interpretarían como parámetros de query o como parámetros de body (JSON).

///

## Sobre "Campos de formulario" { #about-form-fields }

La manera en que los formularios HTML (`<form></form>`) envían los datos al servidor normalmente usa una codificación "especial" para esos datos, es diferente de JSON.

到目前為止，你都是用對應的型別來宣告你需要的請求各部分。

例如從以下來源取得資料：

- 路徑中的參數。
- 標頭。
- Cookies。
- 等等。

這麼做時，FastAPI 會自動驗證並轉換這些資料，還會為你的 API 產生文件。

但有些情況你可能需要直接存取 `Request` 物件。

## 關於 `Request` 物件的細節 { #details-about-the-request-object }

由於 FastAPI 底層其實是 Starlette，再加上一層工具，因此在需要時你可以直接使用 Starlette 的 [`Request`](https://www.starlette.dev/requests/) 物件。

同時也代表，如果你直接從 `Request` 物件取得資料（例如讀取 body），FastAPI 不會替它做驗證、轉換或文件化（透過 OpenAPI 為自動化的 API 介面產生文件）。

Es gibt jedoch Situationen, in denen Sie möglicherweise direkt auf das `Request`-Objekt zugreifen müssen.

## Details zum `Request`-Objekt { #details-about-the-request-object }

## `uvicorn` aufrufen { #call-uvicorn }

Importieren und führen Sie `uvicorn` direkt in Ihrer FastAPI-Anwendung aus:

{* ../../docs_src/debugging/tutorial001_py310.py hl[1,15] *}

### Über `__name__ == "__main__"` { #about-name-main }

Der Hauptzweck von `__name__ == "__main__"` ist, dass Code ausgeführt wird, wenn Ihre Datei mit folgendem Befehl aufgerufen wird:

<div class="termy">

```console
$ python myapp.py
```

</div>

Porém há situações em que você possa precisar acessar o objeto `Request` diretamente.
