O jeito de usar é muito simples. Por exemplo, para fazer uma requisição `GET`, você escreveria:

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

A contra-parte na aplicação FastAPI, a operação de rota, poderia ficar assim:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

Veja as similaridades em `requests.get(...)` e `@app.get(...)`.

Frühere Versionen von FastAPI (vor <abbr title="vor 2023-03">0.95.0</abbr>) erforderten, dass Sie `Query` als den Defaultwert Ihres Parameters verwendeten, anstatt es innerhalb von `Annotated` zu platzieren. Es besteht eine hohe Wahrscheinlichkeit, dass Sie Code sehen, der es so verwendet, also werde ich es Ihnen erklären.

/// tip | Tipp

Imagine que você queira que o parâmetro seja `item-query`.

Assim:

```
http://127.0.0.1:8000/items/?item-query=foobaritems
```

Mas `item-query` não é um nome de variável Python válido.

O mais próximo seria `item_query`.

Mas você ainda precisa que seja exatamente `item-query`...
