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

     * allowed. But at the same time, it seems wasteful to bother inserting the checkNotNull calls
     * that NullPointerTester wants.
     *
     * (This empty method disables the automatic null testing provided by PackageSanityTests.)
     */
  }

`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：

   *
   * <p>If {@code maximumSize} is zero, elements will be evicted immediately after being loaded into
   * cache. This can be useful in testing, or to disable caching temporarily.
   *
   * <p>This feature cannot be used in conjunction with {@link #maximumWeight}.
   *
   * @param maximumSize the maximum size of the cache

#!/usr/bin/env bash

echo "Running $0"

if [ -n "$TEST_DEBUG" ]; then
	set -x
fi

trap 'catch $LINENO' ERR

# shellcheck disable=SC2120
catch() {
	if [ $# -ne 0 ]; then
		echo "error on line $1"
		echo "dc1 server logs ========="
		cat /tmp/dc1.log
		echo "dc2 server logs ========="
		cat /tmp/dc2.log
	fi

	echo "Cleaning up instances of MinIO"
	set +e
	pkill minio
	pkill mc
	rm -rf /tmp/xl/

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:

            "type": "extra_forbidden",
            "loc": ["header", "tool"],
            "msg": "Extra inputs are not permitted",
            "input": "plumbus",
        }
    ]
}
```

## 밑줄 변환 비활성화하기 { #disable-convert-underscores }

일반적인 헤더 매개변수와 마찬가지로, 매개변수 이름에 밑줄 문자가 있으면 **자동으로 하이픈으로 변환**됩니다.

예를 들어, 코드에 `save_data` 헤더 매개변수가 있으면, 기대되는 HTTP 헤더는 `save-data`이고, 문서에서도 그렇게 표시됩니다.

            throw new ParserConfigurationRuntimeException(e);
        } catch (final SAXException e) {
            throw new SAXRuntimeException(e);
        }
    }

    /**
     * Sets the enable/disable state of XInclude.
     *
     * @param spf
     *            {@link SAXParserFactory}. Must not be {@literal null}.
     * @param state
     *            <code>true</code> to enable XInclude.

            "loc": ["header", "tool"],
            "msg": "Extra inputs are not permitted",
            "input": "plumbus",
        }
    ]
}
```

## Automatische Umwandlung von Unterstrichen deaktivieren { #disable-convert-underscores }

Ähnlich wie bei regulären Header-Parametern werden bei der Verwendung von Unterstrichen in den Parameternamen diese **automatisch in Bindestriche umgewandelt**.
