FastAPI converts the configurations to **JSON** to make them compatible with JavaScript, as that's what Swagger UI needs.

## Disable Syntax Highlighting { #disable-syntax-highlighting }

For example, you could disable syntax highlighting in Swagger UI.

Without changing the settings, syntax highlighting is enabled by default:

     * Adjusts fragment size for mobile devices.
     *
     * @return the highlight information
     */
    public HighlightInfo createHighlightInfo() {
        return LaRequestUtil.getOptionalRequest().map(req -> {
            final HighlightInfo highlightInfo = new HighlightInfo();
            final String widthStr = req.getParameter(SCREEN_WIDTH);
            if (StringUtil.isNotBlank(widthStr)) {

`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：

# Whether to detect boundary position in query highlighting.
query.highlight.boundary.position.detect=true
# Type for text fragment in query highlighting.
query.highlight.text.fragment.type=query
# Size for text fragment in query highlighting.
query.highlight.text.fragment.size=3
# Prefix length for text fragment in query highlighting.
query.highlight.text.fragment.prefix.length=5

     * Processes special query prefixes (allinurl:, allintitle:) and initializes
     * request-scoped attributes for highlighting and field logging.
     * @param queryString The query string to process.
     * @param isQuery Whether this is a search query (enables highlighting and logging).
     */
    @SuppressWarnings("unchecked")
    public QueryContext(final String queryString, final boolean isQuery) {

`swagger_ui_parameters`는 Swagger UI에 직접 전달된 구성을 포함하는 딕셔너리를 받습니다.

FastAPI는 이 구성을 **JSON** 형식으로 변환하여 JavaScript와 호환되도록 합니다. 이는 Swagger UI에서 필요로 하는 형식입니다.

## 구문 강조 비활성화 { #disable-syntax-highlighting }

예를 들어, Swagger UI에서 구문 강조 기능을 비활성화할 수 있습니다.

설정을 변경하지 않으면, 기본적으로 구문 강조 기능이 활성화되어 있습니다:

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

그러나 `syntaxHighlight`를 `False`로 설정하여 구문 강조 기능을 비활성화할 수 있습니다:
