Você também pode transmitir vídeo ou áudio desta forma; pode até ser gerado enquanto você processa e envia.

## Um `StreamingResponse` com `yield` { #a-streamingresponse-with-yield }

Se você declarar `response_class=StreamingResponse` na sua função de operação de rota, você pode usar `yield` para enviar cada bloco de dados em sequência.

val runtimeAware: NamedDomainObjectProvider<DependencyScopeConfiguration> = configurations.dependencyScope("runtimeAware") {
    description = "All dependencies which should run in a Gradle context, and therefore must declare or inherit target runtime compatibility"
}

// Computes a map of all projects in the full Gradle distribution to their target runtime details file.

Por ejemplo, podrías declarar que algo podría ser un `str` o `None`:

```python
from typing import Union


def say_hi(name: Union[str, None]):
        print(f"Hi {name}!")
```

`typing` también tiene un atajo para declarar que algo podría ser `None`, con `Optional`.

Aquí va un Consejo desde mi punto de vista muy subjetivo:

"""
Regression test, Error 422 if Form is declared before File
See https://github.com/tiangolo/fastapi/discussions/9116
"""

from pathlib import Path
from typing import Annotated

import pytest
from fastapi import FastAPI, File, Form
from fastapi.testclient import TestClient

app = FastAPI()


@app.post("/file_before_form")
def file_before_form(
    file: bytes = File(),
    city: str = Form(),
):

You can easily use the same Pydantic settings to configure your generated OpenAPI and the docs UIs.

For example:

{* ../../docs_src/conditional_openapi/tutorial001_py310.py hl[6,11] *}

Here we declare the setting `openapi_url` with the same default of `"/openapi.json"`.

And then we use it when creating the `FastAPI` app.

## `Header`'ı Import Edin { #import-header }

Önce `Header`'ı import edin:

{* ../../docs_src/header_params/tutorial001_an_py310.py hl[3] *}

## `Header` Parametrelerini Tanımlayın { #declare-header-parameters }

Ardından header parametrelerini, `Path`, `Query` ve `Cookie` ile kullandığınız yapının aynısıyla tanımlayın.

Default değeri ve ek validation ya da annotation parametrelerinin tamamını belirleyebilirsiniz:

/// warning | Uyarı

`Field`'ın, diğerlerinin (`Query`, `Path`, `Body` vb.) aksine `fastapi`'den değil doğrudan `pydantic`'den import edildiğine dikkat edin.

///

## Model attribute'larını tanımlayın { #declare-model-attributes }

Ardından `Field`'ı model attribute'larıyla birlikte kullanabilirsiniz:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[11:14] *}

/// warning | Попередження

Зверніть увагу, що `Field` імпортується безпосередньо з `pydantic`, а не з `fastapi`, як усе інше (`Query`, `Path`, `Body` тощо).

///

## Оголошення атрибутів моделі { #declare-model-attributes }

Потім ви можете використовувати `Field` з атрибутами моделі:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[11:14] *}
