<div class="termy">

```console
$ ADMIN_EMAIL="deadpool@example.com" APP_NAME="ChimichangApp" fastapi run main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)

하나의 명령에 여러 env var를 설정하려면 공백으로 구분하고, 모두 명령 앞에 두세요.

///

그러면 `admin_email` 설정은 `"deadpool@example.com"`으로 설정됩니다.

`app_name`은 `"ChimichangApp"`이 됩니다.

<div class="termy">

```console
$ ADMIN_EMAIL="deadpool@example.com" APP_NAME="ChimichangApp" fastapi run main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

/// tip

要為單一指令設定多個環境變數，只要用空白分隔它們，並全部放在指令前面即可。

///

如此一來，`admin_email` 設定會被設為 `"deadpool@example.com"`。

`app_name` 會是 `"ChimichangApp"`。

**FastAPI** te permite declarar información adicional y validación para tus parámetros.

Tomemos esta aplicación como ejemplo:

{* ../../docs_src/query_params_str_validations/tutorial001_py310.py hl[7] *}

 *
 * <p>The size of the data structure used by ArrayBasedCharEscaper and ArrayBasedUnicodeEscaper is
 * proportional to the highest valued character that has a replacement. For example a replacement
 * map containing the single character '{@literal \}u1000' will require approximately 16K of memory.
 * As such sharing this data structure between escaper instances is the primary goal of this class.
 *

- Suffixing is very important, when adding Turkish suffixes to the English words, do that based on the pronunciation of the word and with an apostrophe.

- Suffixes also changes based on what word comes next in Turkish too, here is an example:

"Server'a gelen request'leri intercept... " or this could have been "request'e", "request'i" etc.

- Some words are tricky like "path'e" can't be used like "path'a" but it could have been "path'i" "path'leri" etc.

 * This class is used to encapsulate the header information for HTTP requests.
 * It provides methods to get and set the name and value of the header,
 * as well as a method to validate the header.
 *
 * <p>Example usage:</p>
 * <pre>
 *     RequestHeader header = new RequestHeader("Content-Type", "application/json");
 *     String name = header.getName();
 *     String value = header.getValue();

/// tip | 豆知識

ここで、`tokenUrl="token"`は、まだ作成していない相対URL`token`を指します。相対URLなので、`./token`と同じです。

相対URLを使っているので、APIが`https://example.com/`にある場合、`https://example.com/token`を参照します。しかし、APIが`https://example.com/api/v1/`にある場合は`https://example.com/api/v1/token`を参照することになります。

相対 URL を使うことは、[プロキシの背後](../../advanced/behind-a-proxy.md)のような高度なユースケースでもアプリケーションを動作させ続けるために重要です。
