```
http://localhost:8000/items/?q=foo&q=bar
```

würden Sie die mehreren `q`-*Query-Parameter*-Werte (`foo` und `bar`) in einer Python-`list` in Ihrer *Pfadoperation-Funktion* im *Funktionsparameter* `q` erhalten.

So wäre die <abbr title="Response – Antwort: Daten, die der Server zum anfragenden Client zurücksendet">Response</abbr> zu dieser URL:

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
}
```

Então, com uma URL como:

```
http://localhost:8000/items/?q=foo&q=bar
```

você receberá os múltiplos valores do *parâmetro de consulta* `q` (`foo` e `bar`) em uma `list` Python dentro da sua *função de operação de rota*, no *parâmetro da função* `q`.

Assim, a resposta para essa URL seria:

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
}
```

        assertCollectorState(0, 0, 0, collector);

        assertEquals("foo-3.8.1", (out.getDependencies().get(0)).getVersion());
    }

    @Test
    public void testBasedir() throws Exception {
        Model model = new Model(org.apache.maven.api.model.Model.newBuilder()
                .version("3.8.1")
                .artifactId("foo")

            min_length=3,
            max_length=50,
            pattern="^fixedquery$",
            deprecated=True,
        ),
    ] = None,
):
    results = {"items": [{"item_id": "Foo"}, {"item_id": "Bar"}]}
    if q:
        results.update({"q": q})

from fastapi import FastAPI

app = FastAPI(docs_url="/documentation", redoc_url=None)


@app.get("/items/")
async def read_items():

    assertEquals("", Files.getFileExtension("blah."));
    assertEquals("", Files.getFileExtension(".blah."));
    assertEquals("", Files.getFileExtension("/foo.bar/blah"));
    assertEquals("", Files.getFileExtension("/foo/.bar/blah"));
  }

  public void testGetNameWithoutExtension() {
    assertEquals("", Files.getNameWithoutExtension(".txt"));

Тоді, у випадку запиту за URL:

```
http://localhost:8000/items/?q=foo&q=bar
```

Ви отримаєте кілька значень *query параметра* `q` (`foo` і `bar`) у вигляді списку `list` в Python у Вашій *функції обробки шляху*, у *параметрі функції* `q`.

Отже, відповідь на цей URL буде:

```JSON
{
  "q": [
    "foo",
    "bar"
  ]
}
```

   * {@code Optional} class. However, this common usage:
   *
   * {@snippet :
   * for (Foo foo : possibleFoo.asSet()) {
   *   doSomethingWith(foo);
   * }
   * }
   *
   * ... can be replaced with:
   *
   * {@snippet :
   * possibleFoo.ifPresent(foo -> doSomethingWith(foo));
   * }
   *
   * <p><b>Java 9 users:</b> some use cases can be written with calls to {@code optional.stream()}.
