## Subnet Health

Então, para que tudo funcione corretamente, é melhor especificar explicitamente as origens permitidas.

## Usar `CORSMiddleware`

Você pode configurá-lo em sua aplicação **FastAPI** usando o `CORSMiddleware`.

* Importe `CORSMiddleware`.
* Crie uma lista de origens permitidas (como strings).
* Adicione-a como um "middleware" à sua aplicação **FastAPI**.

To see an example, check the [Project Generators](../project-generation.md){.internal-link target=_blank}, they all include Celery already configured.

But if you need to access variables and objects from the same **FastAPI** app, or you need to perform small background tasks (like sending an email notification), you can simply just use `BackgroundTasks`.

  /**
   * This test creates a long random sequence of inputs, then a lot of differently configured sinks
   * process it; all should produce the same answer, the only difference should be the number of
   * process()/processRemaining() invocations, due to alignment.

first connect fails. This is necessary for IPv4+IPv6 and services hosted in redundant data
centers. OkHttp supports modern TLS features (TLS 1.3, ALPN, certificate pinning). It can be
configured to fall back for broad connectivity.

Using OkHttp is easy. Its request/response API is designed with fluent builders and immutability. It
supports both synchronous blocking calls and async calls with callbacks.

### [Connections](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-connection/)

When you request a URL with OkHttp, here's what it does:

 1. It uses the URL and configured OkHttpClient to create an **address**. This address specifies how we'll connect to the webserver.
 2. It attempts to retrieve a connection with that address from the **connection pool**.

## URL da OpenAPI

Por padrão, o esquema OpenAPI é servido em `/openapi.json`.

Mas você pode configurá-lo com o parâmetro `openapi_url`.

Por exemplo, para defini-lo para ser servido em `/api/v1/openapi.json`:

```Python hl_lines="3"
{!../../docs_src/metadata/tutorial002.py!}
```

        for (MavenProject p : projectsInRequestScope) {
            if ("bom".equals(p.getPackaging())) {
                LOGGER.info(
                        "The packaging attribute of the '{}' project is configured as 'bom' and changed to 'pom'",
                        p.getName());
                p.setPackaging("pom");
            }
        }
    }
