Damit das funktioniert, müssen Sie `pip install python-dotenv` ausführen.

///

### Die `.env`-Datei

Sie könnten eine `.env`-Datei haben, mit:

```bash

```Python hl_lines="2"
{!../../docs_src/python_types/tutorial001.py!}
```

### Bewerk het

Dit is een heel eenvoudig programma.

Maar stel je nu voor dat je het vanaf nul zou moeten maken.

Op een gegeven moment zou je aan de definitie van de functie zijn begonnen, je had de parameters klaar...

Maar dan moet je “die methode die de eerste letter naar hoofdletters converteert” aanroepen.

/// tip

For this to work, you need to `pip install python-dotenv`.

///

### The `.env` file

You could have a `.env` file with:

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

这种做法相当常见，有一个名称，这些环境变量通常放在一个名为 `.env` 的文件中，该文件被称为“dotenv”。

/// tip

以点 (`.`) 开头的文件是 Unix-like 系统（如 Linux 和 macOS）中的隐藏文件。

但是，dotenv 文件实际上不一定要具有确切的文件名。

///

Pydantic 支持使用外部库从这些类型的文件中读取。您可以在<a href="https://docs.pydantic.dev/latest/concepts/pydantic_settings/#dotenv-env-support" class="external-link" target="_blank">Pydantic 设置: Dotenv (.env) 支持</a>中阅读更多相关信息。

/// dica

Para que isso funcione você precisa executar `pip install python-dotenv`.

### O arquivo `.env`

Você pode definir um arquivo `.env` com o seguinte conteúdo:

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

     * @param timeout
     * @return
     * @throws IOException
     */
    protected <T extends Response> long doSend ( Request request, T response, Set<RequestParam> params, long timeout ) throws IOException {
        long firstKey = prepareRequests(request, response, params, timeout);
        doSend(request);
        return firstKey;
    }


    /**
     * @param request
     * @param response

  depguard:
    rules:
      DenyGogoProtobuf:
        files:
          - $all
        deny:
          - pkg: github.com/gogo/protobuf
            desc: "gogo/protobuf is deprecated, use golang/protobuf"
      # deny for all go files
      AllGoFiles:
        files:
          - $all
        deny:
          - pkg: golang.org/x/net/http2/h2c
