3.  Files should be formatted according to Google's [Java style guide][].
4.  Do your best to have a [well-formed commit message][] for the change.
5.  Pull requests typically do not need to modify the files under the `android`
    directory: We have a script that automatically mirrors changes from the main
    directories into the `android` directories.

# Tutorial - Guia de Usuário { #tutorial-user-guide }

Esse tutorial mostra como usar o **FastAPI** com a maior parte de seus recursos, passo a passo.

Cada seção constrói, gradualmente, sobre as anteriores, mas sua estrutura são tópicos separados, para que você possa ir a qualquer um específico e resolver suas necessidades específicas de API.

Ele também foi construído para servir como uma referência futura, então você pode voltar e ver exatamente o que você precisa.

    response = client.get("/items?id=isbn-9781529046137")
    assert response.status_code == 200, response.text
    assert response.json() == {
        "id": "isbn-9781529046137",
        "name": "The Hitchhiker's Guide to the Galaxy",
    }


def test_get_item_does_not_exist(client: TestClient):
    response = client.get("/items?id=isbn-nope")
    assert response.status_code == 200, response.text

Bu, bir `APIRouter` kullanmaktan farklıdır çünkü bağlanmış bir uygulama tamamen bağımsızdır. Ana uygulamanızın OpenAPI ve dokümanlar, bağlanmış uygulamadan hiçbir şey içermez, vb.

Here’s a [sample event listener](https://github.com/square/okhttp/blob/master/samples/guide/src/main/java/okhttp3/recipes/PrintEventsNonConcurrent.java) that prints each event with a timestamp.

```java
class PrintingEventListener extends EventListener {
