Aqui nós usamos para criar um `GzipRequest` a partir da requisição original.

{* ../../docs_src/custom_request_and_route/tutorial001.py hl[18:26] *}

/// note | Detalhes Técnicos

Um `Request` também tem um `request.receive`, que é uma função para "receber" o corpo da requisição.

Um `Request` também tem um `request.receive`, que é uma função para "receber" o corpo da requisição.

Para o tutorial, você deve querer instalá-lo com todas as dependências e recursos opicionais.

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

/// note | Nota

Quando você instala com pip install "fastapi[standard]", ele vem com algumas dependências opcionais padrão.

Se você não quiser ter essas dependências opcionais, pode instalar pip install fastapi em vez disso.

//   - fivs.FreeVersions has all the free versions
//
// if inclFreeVersions is true all the versions are in fivs.Versions, free and non-free versions alike.
//
// Note: Only the scanner requires fivs.Versions to have exclusively non-free versions. This is used while enforcing NewerNoncurrentVersions lifecycle element.

```

Then, declare your *path operation functions* with `async def` like:

```Python hl_lines="2"
@app.get('/')
async def read_results():
    results = await some_library()
    return results
```

/// note

You can only use `await` inside of functions created with `async def`.

## 「フォームフィールド」について

HTMLフォーム（`<form></form>`）がサーバにデータを送信する方法は、通常、そのデータに「特別な」エンコーディングを使用していますが、これはJSONとは異なります。

**FastAPI** は、JSONの代わりにそのデータを適切な場所から読み込むようにします。

/// note | 技術詳細

フォームからのデータは通常、`application/x-www-form-urlencoded`の「media type」を使用してエンコードされます。

しかし、フォームがファイルを含む場合は、`multipart/form-data`としてエンコードされます。ファイルの扱いについては次の章で説明します。
