/// tip | 豆知識

これを機能させるには、`pip install python-dotenv` が必要です。

///

### `.env` ファイル { #the-env-file }

次のような `.env` ファイルを用意できます:

```bash
ADMIN_EMAIL="******@****.***"
APP_NAME="ChimichangApp"
```

### `.env` から設定を読む { #read-settings-from-env }

そして、`config.py` を次のように更新します:

Para o OAuth2, eles são apenas strings.

///

## Visão global { #global-view }

Primeiro, vamos olhar rapidamente as partes que mudam dos exemplos do **Tutorial - Guia de Usuário** para [OAuth2 com Senha (e hash), Bearer com tokens JWT](../../tutorial/security/oauth2-jwt.md). Agora utilizando escopos OAuth2:

{* ../../docs_src/security/tutorial005_an_py310.py hl[5,9,13,47,65,106,108:116,122:126,130:136,141,157] *}

/// tip | 提示

要使其工作，你需要执行 `pip install python-dotenv`。

///

### `.env` 文件 { #the-env-file }

你可以有一个 `.env` 文件，内容如下：

```bash
ADMIN_EMAIL="******@****.***"
APP_NAME="ChimichangApp"
```

### 从 `.env` 中读取设置 { #read-settings-from-env }

然后更新 `config.py`：

{* ../../docs_src/settings/app03_an_py310/config.py hl[9] *}

        // Channel binding requires SMB2_SESSION_FLAG_BINDING (0x01) in session setup

        // Calculate channel binding hash per MS-SMB2 3.2.5.3.1
        byte[] bindingInfo = calculateBindingInfo(channel);
        byte[] bindingHash = calculateBindingHash(bindingInfo);
        channel.setBindingHash(bindingHash);
