import importlib

import pytest
from fastapi.testclient import TestClient


@pytest.fixture(
    name="client",
    params=[
        "tutorial001_py39",
        "tutorial003_py39",
    ],
)
def get_client(request: pytest.FixtureRequest):

In diesem Fall würde der ursprüngliche Pfad `/app` tatsächlich unter `/api/v1/app` bereitgestellt.

Auch wenn Ihr gesamter Code unter der Annahme geschrieben ist, dass es nur `/app` gibt.

{* ../../docs_src/behind_a_proxy/tutorial001_py39.py hl[6] *}

Чтобы отключить её, установите их URL в значение `None` при создании вашего приложения `FastAPI`:

{* ../../docs_src/custom_docs_ui/tutorial001_py39.py hl[8] *}

### Подключить пользовательскую документацию { #include-the-custom-docs }

Теперь вы можете создать *операции пути* для пользовательской документации.

Wenn Sie `lifespan` in Ihren Tests ausführen müssen, können Sie den `TestClient` mit einer `with`-Anweisung verwenden:

{* ../../docs_src/app_testing/tutorial004_py39.py hl[9:15,18,27:28,30:32,41:43] *}


Sie können mehr Details unter [„Lifespan in Tests ausführen in der offiziellen Starlette-Dokumentation.“](https://www.starlette.dev/lifespan/#running-lifespan-in-tests) nachlesen.

Quando você precisa que o `lifespan` seja executado em seus testes, você pode utilizar o `TestClient` com a instrução `with`:

{* ../../docs_src/app_testing/tutorial004_py39.py hl[9:15,18,27:28,30:32,41:43] *}

Você pode ler mais detalhes sobre o ["Executando lifespan em testes no site oficial da documentação do Starlette."](https://www.starlette.dev/lifespan/#running-lifespan-in-tests)

{* ../../docs_src/app_testing/tutorial004_py39.py hl[9:15,18,27:28,30:32,41:43] *}


You can read more details about the ["Running lifespan in tests in the official Starlette documentation site."](https://www.starlette.dev/lifespan/#running-lifespan-in-tests)

For the deprecated `startup` and `shutdown` events, you can use the `TestClient` as follows:

import importlib

import pytest
from fastapi.testclient import TestClient


@pytest.fixture(
    name="client",
    params=[
        pytest.param("tutorial001_py39"),
        pytest.param("tutorial002_py39"),
    ],
)
def get_client(request: pytest.FixtureRequest):
    mod = importlib.import_module(f"docs_src.response_status_code.{request.param}")

    client = TestClient(mod.app)
    return client

En este caso, el path original `/app` realmente sería servido en `/api/v1/app`.

Aunque todo tu código esté escrito asumiendo que solo existe `/app`.

{* ../../docs_src/behind_a_proxy/tutorial001_py39.py hl[6] *}

Let's see the previous example again:

{* ../../docs_src/response_status_code/tutorial001_py39.py hl[6] *}

`201` is the status code for "Created".

But you don't have to memorize what each of these codes mean.

You can use the convenience variables from `fastapi.status`.

{* ../../docs_src/response_status_code/tutorial002_py39.py hl[1,6] *}

Mas é a maneira mais simples de focar no lado do servidor de WebSockets e ter um exemplo funcional:

{* ../../docs_src/websockets/tutorial001_py39.py hl[2,6:38,41:43] *}

## Crie um `websocket` { #create-a-websocket }

Em sua aplicação **FastAPI**, crie um `websocket`:

{* ../../docs_src/websockets/tutorial001_py39.py hl[1,46:47] *}

/// note | Detalhes Técnicos

Você também poderia usar `from starlette.websockets import WebSocket`.
