## Pydantic

Toda a validação de dados é feita por baixo dos panos pelo <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a>, então você tem todos os benefícios disso. E assim você sabe que está em boas mãos.

Você pode usar as mesmas declarações de tipo com `str`, `float`, `bool` e muitos outros tipos complexos de dados.

Vamos explorar muitos destes tipos nos próximos capítulos do tutorial.

## A ordem importa

	// Date and time when the file was last modified, if Deleted
	// is 'true' this value represents when while was deleted.
	ModTime time.Time `msg:"mt"`

	// Total file size.
	Size int64 `msg:"sz"`

	// File mode bits.
	Mode uint32 `msg:"m"`

	// WrittenByVersion is the unix time stamp of the MinIO
	// version that created this version of the object.
	WrittenByVersion uint64 `msg:"wv"`

Si vous ouvrez la documentation automatique de l'API, votre extension apparaîtra au bas du *chemin* spécifique.

<img src="/img/tutorial/path-operation-advanced-configuration/image01.png">

Et dans le fichier openapi généré (`/openapi.json`), vous verrez également votre extension dans le cadre du *chemin* spécifique :

// If parsing fails or an integer overflow occurs, err will be set.
func (p *parser) parseNumeric(b []byte) int64 {
	// Check for base-256 (binary) format first.
	// If the first bit is set, then all following bits constitute a two's
	// complement encoded number in big-endian byte order.
	if len(b) > 0 && b[0]&0x80 != 0 {
		// Handling negative numbers relies on the following identity:
		//	-a-1 == ^a

Wie Sie sie verwenden und wie sie in **FastAPI** integriert sind, erfahren Sie später im **Handbuch für fortgeschrittene Benutzer**.

## Zusammenfassung

Mit dem, was Sie bis hier gesehen haben, können Sie eine sichere **FastAPI**-Anwendung mithilfe von Standards wie OAuth2 und JWT einrichten.

In fast jedem Framework wird die Handhabung der Sicherheit recht schnell zu einem ziemlich komplexen Thema.

Plus jamais vous ne vous tromperez en tapant le nom d'une clé, vous ne ferez des aller-retour entre votre code et la documentation ou vous ne scrollerez de haut en bas afin d'enfin savoir si vous devez taper `username` ou `user_name`.
