## Simple HTTP Basic Auth

* Importa `HTTPBasic` y `HTTPBasicCredentials`.
* Crea un "esquema de `security`" usando `HTTPBasic`.
* Usa ese `security` con una dependencia en tu *path operation*.
* Devuelve un objeto de tipo `HTTPBasicCredentials`:
  * Contiene el `username` y `password` enviados.

Prefer to use the `Annotated` version if possible.

/// tip | Consejo

El "PATCH" es el último número, por ejemplo, en `0.2.3`, la versión PATCH es `3`.

///

Así que deberías poder fijar a una versión como:

```txt
fastapi>=0.45.0,<0.46.0
```

Los cambios incompatibles y nuevas funcionalidades se añaden en versiones "MINOR".

/// tip | Consejo

/// tip

The "PATCH" is the last number, for example, in `0.2.3`, the PATCH version is `3`.

///

So, you should be able to pin to a version like:

```txt
fastapi>=0.45.0,<0.46.0
```

Breaking changes and new features are added in "MINOR" versions.

/// tip

# Environment Variables { #environment-variables }

/// tip

If you already know what "environment variables" are and how to use them, feel free to skip this.

///

An environment variable (also known as "**env var**") is a variable that lives **outside** of the Python code, in the **operating system**, and could be read by your Python code (or by other programs as well).

# Omgevingsvariabelen

/// tip

Als je al weet wat "omgevingsvariabelen" zijn en hoe je ze kunt gebruiken, kun je deze stap gerust overslaan.

///

Een omgevingsvariabele (ook bekend als "**env var**") is een variabele die **buiten** de Python-code leeft, in het **besturingssysteem** en die door je Python-code (of door andere programma's) kan worden gelezen.

E então o **FastAPI** chamará a sobreposição no lugar da dependência original.

{* ../../docs_src/dependency_testing/tutorial001_an_py310.py hl[26:27,30] *}

/// tip | Dica

Você pode definir uma sobreposição de dependência para uma dependência que é utilizada em qualquer lugar da sua aplicação **FastAPI**.
