La documentación interactiva de API se actualizará en consecuencia, para permitir múltiples valores:

<img src="/img/tutorial/query-params-str-validations/image02.png">

### Lista de parámetros de Query / múltiples valores con valores por defecto { #query-parameter-list-multiple-values-with-defaults }

        final Map<String, Object> params = new HashMap<>();
        params.put("str", "hello");
        params.put("num", 42);
        params.put("bool", true);
        params.put("dbl", 3.14);

        assertEquals("hello", groovyEngine.evaluate("return str", params));
        assertEquals(42, groovyEngine.evaluate("return num", params));
        assertEquals(true, groovyEngine.evaluate("return bool", params));

    Map<String, String> map =
        ImmutableMap.of(
            "canada", "dollar",
            "chile", "peso",
            "switzerland", "franc");
    HashBiMap<String, String> bimap = HashBiMap.create(map);
    assertThat(bimap.get("canada")).isEqualTo("dollar");
    assertThat(bimap.inverse().get("dollar")).isEqualTo("canada");
  }

  private static final int N = 1000;

Önceki örneğe tekrar bakalım:

{* ../../docs_src/response_status_code/tutorial001_py310.py hl[6] *}

`201`, "Created" için kullanılan status code'dur.

Ancak bu kodların her birinin ne anlama geldiğini ezberlemek zorunda değilsiniz.

`fastapi.status` içindeki kolaylık değişkenlerini (convenience variables) kullanabilirsiniz.

{* ../../docs_src/response_status_code/tutorial002_py310.py hl[1,6] *}

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

/// tip | 提示

要声明类型为 `list` 的查询参数（如上例），你需要显式地使用 `Query`，否则它会被解释为请求体。

///

交互式 API 文档会相应更新，以支持多个值：

<img src="/img/tutorial/query-params-str-validations/image02.png">

### 具有默认值的查询参数列表 / 多个值 { #query-parameter-list-multiple-values-with-defaults }

你还可以定义在没有给定值时的默认 `list`：

Puedes declarar "parámetros" o "variables" de path con la misma sintaxis que se usa en los format strings de Python:

{* ../../docs_src/path_params/tutorial001_py310.py hl[6:7] *}

El valor del parámetro de path `item_id` se pasará a tu función como el argumento `item_id`.

Así que, si ejecutas este ejemplo y vas a [http://127.0.0.1:8000/items/foo](http://127.0.0.1:8000/items/foo), verás un response de:

```JSON
{"item_id":"foo"}
```

* `needy`, un `str` requerido.
* `skip`, un `int` con un valor por defecto de `0`.
* `limit`, un `int` opcional.

/// tip | Consejo

También podrías usar `Enum`s de la misma manera que con [Parámetros de Path](path-params.md#predefined-values).

{* ../../docs_src/header_params/tutorial001_an_py310.py hl[9] *}

/// note | Technical Details

`Header` is a "sister" class of `Path`, `Query` and `Cookie`. It also inherits from the same common `Param` class.

But remember that when you import `Query`, `Path`, `Header`, and others from `fastapi`, those are actually functions that return special classes.

///

## Documentation { #documentation }

And when you open your browser at [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs), you will see an automatic, interactive, API documentation like:

Again, just with that same Python type declaration, **FastAPI** gives you automatic, interactive documentation (integrating Swagger UI).
