So, you can use `user_agent` as you normally would in Python code, instead of needing to capitalize the first letters as `User_Agent` or something similar.

If for some reason you need to disable automatic conversion of underscores to hyphens, set the parameter `convert_underscores` of `Header` to `False`:

FastAPI convertit les configurations en **JSON** pour les rendre compatibles avec JavaScript, car c'est ce dont Swagger UI a besoin.

## Désactiver la coloration syntaxique { #disable-syntax-highlighting }

Par exemple, vous pourriez désactiver la coloration syntaxique dans Swagger UI.

Sans modifier les paramètres, la coloration syntaxique est activée par défaut :

          ~/.gradle/caches/keyrings/
        key: ${{ runner.os }}-gradle-cache-${{ hashFiles('gradle/wrapper/gradle-wrapper.properties') }}
        if: ${{ matrix.language == 'java' }}

    - name: Disable checksum offloading
      # See: https://github.com/actions/virtual-environments/issues/1187#issuecomment-686735760
      run: sudo ethtool -K eth0 tx off rx off

    # Install and setup JDK 17
    - name: Setup JDK 17

     */
    boolean isOffline();

    /**
     * Enables/disables network access to remote repositories.
     *
     * @param offline {@code true} to disable remote access, {@code false} to allow network access.
     * @return This request, never {@code null}.
     */
    RepositoryRequest setOffline(boolean offline);

    /**

set FESS_JAVA_OPTS=%FESS_JAVA_OPTS% -Dlog4j.shutdownHookEnabled=false

set FESS_JAVA_OPTS=%FESS_JAVA_OPTS% -Dlog4j2.formatMsgNoLookups=true
set FESS_JAVA_OPTS=%FESS_JAVA_OPTS% -Dlog4j.skipJansi=true

REM SSL truststore for certificate validation over https

`swagger_ui_parameters` 接受一個 dict，內容會直接傳給 Swagger UI 作為設定。

FastAPI 會把這些設定轉換成 **JSON**，以便與 JavaScript 相容，因為 Swagger UI 需要的是這種格式。

## 停用語法醒目提示 { #disable-syntax-highlighting }

例如，你可以在 Swagger UI 中停用語法醒目提示（syntax highlighting）。

不更動設定時，語法醒目提示預設為啟用：

<img src="/img/tutorial/extending-openapi/image02.png">

但你可以將 `syntaxHighlight` 設為 `False` 來停用它：

    return {"fresh_value": fresh_value}
```

disable consideration of cgroup limits. This setting only affects Linux.

Go 1.25 added a new `updatemaxprocs` setting that controls whether the Go
runtime will periodically update GOMAXPROCS for new CPU affinity or cgroup
limits. The default value `updatemaxprocs=1` will enable periodic updates.
`updatemaxprocs=0` will disable periodic updates.

Most tasks that are used to build Gradle support the configuration cache, but some don't. For example, building the documentation currently requires you to disable the configuration cache.

To disable the configuration cache, run the build with `--no-configuration-cache`.

Tasks known to have problems are listed in the build logic. You can find this list at:
