# Tutoriel - Guide utilisateur { #tutorial-user-guide }

Ce tutoriel vous montre comment utiliser **FastAPI** avec la plupart de ses fonctionnalités, étape par étape.

Chaque section s'appuie progressivement sur les précédentes, mais elle est structurée de manière à séparer les sujets, afin que vous puissiez aller directement à l'un d'entre eux pour répondre à vos besoins spécifiques d'API.

      streamId: Int,
      windowSizeIncrement: Long,
    )

    /**
     * Called when reading a headers or priority frame. This may be used to change the stream's
     * weight from the default (16) to a new value.
     *
     * @param streamId stream which has a priority change.
     * @param streamDependency the stream ID this stream is dependent on.
     * @param weight relative proportion of priority in `[1..256]`.

        byte[] buffer = new byte[34];
        long create = 1600000000000L;
        long lastAccess = 1600000100000L;
        long lastWrite = 1600000200000L;
        long change = 1600000300000L;
        int attributes = 0x1234;
        // Convert Unix time to Windows FILETIME (100-nanosecond intervals since 1601)
        long MILLISECONDS_BETWEEN_1970_AND_1601 = 11644473600000L;

...e então o Swagger UI não mostrará mais o destaque de sintaxe:

<img src="/img/tutorial/extending-openapi/image03.png">

## Alterar o tema { #change-the-theme }

Da mesma forma que você pode definir o tema de destaque de sintaxe com a chave `"syntaxHighlight.theme"` (observe que há um ponto no meio):

{* ../../docs_src/configure_swagger_ui/tutorial002_py310.py hl[3] *}

{* ../../docs_src/configure_swagger_ui/tutorial001_py310.py hl[3] *}

...ve ardından Swagger UI artık syntax highlighting'i göstermeyecektir:

<img src="/img/tutorial/extending-openapi/image03.png">

## Temayı Değiştirin { #change-the-theme }

Aynı şekilde, `"syntaxHighlight.theme"` anahtarıyla (ortasında bir nokta olduğuna dikkat edin) syntax highlighting temasını ayarlayabilirsiniz:

{* ../../docs_src/configure_swagger_ui/tutorial002_py310.py hl[3] *}

	HandlerCheckParts2
	HandlerRenamePart
	HandlerClearUploadID
	HandlerCheckParts3

	// Add more above here ^^^
	// If all handlers are used, the type of Handler can be changed.
	// Handlers have no versioning, so non-compatible handler changes must result in new IDs.
	handlerTest
	handlerTest2
	handlerLast
)

// handlerPrefixes are prefixes for handler IDs used for tracing.

You also get error checks for incorrect type operations:

This is not by chance, the whole framework was built around that design.

And it was thoroughly tested at the design phase, before any implementation, to ensure it would work with all the editors.

There were even some changes to Pydantic itself to support this.

		},
		config.HelpKV{
			Key:         apiStaleUploadsCleanupInterval,
			Description: `set to change intervals when stale multipart uploads are expired` + defaultHelpPostfix(apiStaleUploadsCleanupInterval),
			Optional:    true,
			Type:        "duration",
		},
		config.HelpKV{
			Key:         apiDeleteCleanupInterval,

{* ../../docs_src/configure_swagger_ui/tutorial001_py310.py hl[3] *}

...після цього Swagger UI більше не показуватиме підсвітку синтаксису:

<img src="/img/tutorial/extending-openapi/image03.png">

## Змініть тему { #change-the-theme }

Так само ви можете задати тему підсвітки синтаксису ключем `"syntaxHighlight.theme"` (зверніть увагу, що посередині є крапка):

{* ../../docs_src/configure_swagger_ui/tutorial002_py310.py hl[3] *}

{* ../../docs_src/configure_swagger_ui/tutorial001_py310.py hl[3] *}

…и после этого Swagger UI больше не будет показывать подсветку синтаксиса:

<img src="/img/tutorial/extending-openapi/image03.png">

## Изменить тему { #change-the-theme }

Аналогично вы можете задать тему подсветки синтаксиса с ключом "syntaxHighlight.theme" (обратите внимание, что посередине стоит точка):

{* ../../docs_src/configure_swagger_ui/tutorial002_py310.py hl[3] *}
