Así que, si ejecutas este ejemplo y vas a <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a>, verás un response de:

```JSON
{"item_id":"foo"}
```

## Parámetros de path con tipos { #path-parameters-with-types }

Puedes declarar el tipo de un parámetro de path en la función, usando anotaciones de tipos estándar de Python:

            }
        };

        // Test with timeout set
        client.setAccessTimeout(10);
        try {
            ResponseData result = client.doGet("file://test.txt");
            assertNotNull("Response should not be null", result);
            assertEquals(200, result.getHttpStatusCode());
        } catch (Exception e) {
            fail("Should not throw exception: " + e.getMessage());
        }

        bool,
        Doc(
            """
            Load and use Google Fonts.
            """
        ),
    ] = True,
) -> HTMLResponse:
    """
    Generate and return the HTML response that loads ReDoc for the alternative
    API docs (normally served at `/redoc`).

    You would only call this function yourself if you needed to override some parts,

de una autenticación fallida, usaban el código de estado HTTP `403 Forbidden`.

A partir de FastAPI versión `0.122.0`, usan el código de estado HTTP `401 Unauthorized`, más apropiado, y devuelven un `WWW-Authenticate` header adecuado en la response, siguiendo las especificaciones HTTP, <a href="https://datatracker.ietf.org/doc/html/rfc7235#section-3.1" class="external-link" target="_blank">RFC 7235</a>, <a href="https://datatracker.ietf.org/doc/html/rfc9110#name-401-unauthorized" class="external-link"...

2. For some Python-specific terms like "pickle", "list", "dict" etc, we don't have to translate them.
3. Use the following preferred translations when they apply in documentation prose:

- request (HTTP): 請求
- response (HTTP): 回應
- path operation: 路徑操作
- path operation function: 路徑操作函式

Именно поэтому на официальном сайте сказано:

> Requests — один из самых загружаемых Python-пакетов всех времён

Пользоваться им очень просто. Например, чтобы сделать запрос `GET`, вы бы написали:

```Python
response = requests.get("http://example.com/some/url")
```

Соответствующая в FastAPI API-операция пути могла бы выглядеть так:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
