This is very useful when you need to:

* Have shared logic (the same code logic again and again).
* Share database connections.
* Enforce security, authentication, role requirements, etc.
* And many other things...

All these, while minimizing code repetition.

## First Steps { #first-steps }

### Безопасность и аутентификация { #security-and-authentication }

Встроенные функции безопасности и аутентификации. Без каких‑либо компромиссов с базами данных или моделями данных.

Все схемы безопасности, определённые в OpenAPI, включая:

* HTTP Basic.
* **OAuth2** (также с **токенами JWT**). Ознакомьтесь с руководством [OAuth2 с JWT](tutorial/security/oauth2-jwt.md){.internal-link target=_blank}.
* Ключи API в:

and [C++](https://www.tensorflow.org/api_docs/cc) APIs, as well as a
non-guaranteed backward compatible API for
[other languages](https://www.tensorflow.org/api_docs).

## Install

It is a project from the Linux Foundation. It provides **HTTPS certificates for free**, in an automated way. These certificates use all the standard cryptographic security, and are short-lived (about 3 months), so the **security is actually better** because of their reduced lifespan.

The domains are securely verified and the certificates are generated automatically. This also allows automating the renewal of these certificates.

### Segurança e autenticação { #security-and-authentication }

Segurança e autenticação integradas. Sem nenhum compromisso com bancos de dados ou modelos de dados.

Todos os esquemas de seguranças definidos no OpenAPI, incluindo:

* HTTP Basic.
* **OAuth2** (também com **tokens JWT**). Confira o tutorial em [OAuth2 com JWT](tutorial/security/oauth2-jwt.md){.internal-link target=_blank}.
* Chaves de API em:

These examples are intentionally simple, but show how it all works.

In the chapters about security, there are utility functions that are implemented in this same way.

If you understood all this, you already know how those utility tools for security work underneath.

이 예시에서 `X-Key`와 `X-Token`이라는 커스텀 헤더를 만들어 사용했습니다.

그러나 실제로 보안을 구현할 때는 통합된 [보안 유틸리티 (다음 챕터)](../security/index.md){.internal-link target=_blank}를 사용하는 것이 더 많은 이점을 얻을 수 있습니다.

평소에 사용하던대로 같은 의존성 *함수*를 사용할 수 있습니다.
