### Шаг 3: определите *операцию пути (path operation)*

#### Путь (path)

"Путь" это часть URL, после первого символа `/`, следующего за именем домена.

Для URL:

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

...путь выглядит так:

```
/items/foo
```

/// info | "Дополнительная иформация"

Термин "path" также часто называется "endpoint" или "route".

///

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

Se você usar Hypercorn, ele também tem a opção `--root-path`.

/// note | "Detalhes Técnicos"

A especificação ASGI define um `root_path` para esse caso de uso.

E a opção de linha de comando `--root-path` fornece esse `root_path`.

///
