Aprenderás más sobre cómo usar variables de entorno para manejar **configuraciones de aplicación** en la [Guía del Usuario Avanzado - Ajustes y Variables de Entorno](./advanced/settings.md){.internal-link target=_blank}.

## Variable de Entorno `PATH`

        String configParam = "new.param=value\nconfig.setting=true";
        ParameterUtil.loadConfigParams(targetMap, configParam);
        assertEquals(3, targetMap.size());
        assertEquals("value", targetMap.get("existing"));
        assertEquals("value", targetMap.get("new.param"));
        assertEquals("true", targetMap.get("config.setting"));
    }

    public void test_performanceAndBoundary() {

MINIO_IDENTITY_OPENID_REDIRECT_URI_DYNAMIC  (on|off)    Enable 'Host' header based dynamic redirect URI (default: 'off')
MINIO_IDENTITY_OPENID_COMMENT               (sentence)  optionally add a comment to this setting
```

### Access Control Configuration Variables

    /** Session manager for handling HTTP session operations. */
    @Resource
    protected SessionManager sessionManager;

    /** Configuration manager for Fess application settings. */
    @Resource
    protected FessConfig fessConfig;

    /** Helper for managing user activity logging and tracking. */
    @Resource
    protected ActivityHelper activityHelper;

* `skip=20`: because you set it in the URL
* `limit=10`: because that was the default value

## Optional parameters { #optional-parameters }

The same way, you can declare optional query parameters, by setting their default to `None`:

{* ../../docs_src/query_params/tutorial002_py310.py hl[7] *}

In this case, the function parameter `q` will be optional, and will be `None` by default.

/// check

  alias realpath=grealpath
  alias stat=gstat
  # By default, aliases are only expanded in interactive shells, which means
  # that they are not substituted for their corresponding commands in shell
  # scripts. By setting "expand_aliases", we enable alias expansion in
  # non-interactive shells as well.
  shopt -s expand_aliases
else
  echo '==TFCI==: Error: Cannot find path to grealpath or gstat'

 * such as index, size, tags, roles, fields, languages, and exclusion words.
 *
 * <p>Key functionalities include:</p>
 * <ul>
 *   <li>Setting the target index for the search.</li>
 *   <li>Limiting the number of results (size).</li>
 *   <li>Filtering by tags, roles, fields, and languages.</li>
 *   <li>Excluding specific words from the results.</li>

There are some additional dependencies you might want to install.

Additional optional Pydantic dependencies:

* <a href="https://docs.pydantic.dev/latest/usage/pydantic_settings/" target="_blank"><code>pydantic-settings</code></a> - for settings management.
* <a href="https://docs.pydantic.dev/latest/usage/types/extra_types/extra_types/" target="_blank"><code>pydantic-extra-types</code></a> - for extra types to be used with Pydantic.
