### Étape 3: créer une *opération de chemin*

#### Chemin

Chemin, ou "path" fait référence ici à la dernière partie de l'URL démarrant au premier `/`.

Donc, dans un URL tel que :

```
https://example.com/items/foo
```

...le "path" serait :

```
/items/foo
```

/// info

   * checked exceptions.
   */
  public class CheckedBarrier extends CyclicBarrier {
    public CheckedBarrier(int parties) {
      super(parties);
    }

    @Override
    public int await() {
      try {
        return super.await(2 * LONG_DELAY_MS, MILLISECONDS);
      } catch (TimeoutException e) {

# Simples OAuth2 com senha e Bearer { #simple-oauth2-with-password-and-bearer }

Agora vamos construir a partir do capítulo anterior e adicionar as partes que faltam para ter um fluxo de segurança completo.

## Obtenha o `username` e a `password` { #get-the-username-and-password }

É utilizado o utils de segurança da **FastAPI** para obter o `username` e a `password`.

        i += 4;

        assert i == body.length;
        return body;
    }

    /**
     * Build a CREATE response body with a single, unrecognized create context.
     * The parser should iterate it but produce an empty contexts array.
     */
    private static byte[] buildCreateBodyWithContext(byte[] fileId, int contextStartOffsetFromHeader) {

// Blocks will read this much and find the first following newline.
// 128KB appears to be a very reasonable default.
const csvSplitSize = 128 << 10

// startReaders will read the header if needed and spin up a parser
// and a number of workers based on GOMAXPROCS.
// If an error is returned no goroutines have been started and r.err will have been set.
func (r *Reader) startReaders(newReader func(io.Reader) *csv.Reader) error {

## Prérequis

FastAPI repose sur les épaules de géants :

* <a href="https://www.starlette.dev/" class="external-link" target="_blank">Starlette</a> pour les parties web.
* <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> pour les parties données.

## Installation

<div class="termy">

```console
$ pip install fastapi

---> 100%
```

</div>

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[22] *}

/// tip | Consejo

Todo esto podría parecer complicado. Y puede que no esté muy claro cómo es útil aún.

Estos ejemplos son intencionalmente simples, pero muestran cómo funciona todo.

# Primeiros Passos { #first-steps }

O arquivo FastAPI mais simples pode se parecer com:

{* ../../docs_src/first_steps/tutorial001_py39.py *}

Copie o conteúdo para um arquivo `main.py`.

Execute o servidor:

<div class="termy">

```console
