其他有用的场景是当你想要接收其他类型的键时，例如 `int`。

这也是我们在接下来将看到的。

在下面的例子中，你将接受任意键为 `int` 类型并且值为 `float` 类型的 `dict`：

{* ../../docs_src/body_nested_models/tutorial009_py39.py hl[7] *}

/// tip

请记住 JSON 仅支持将 `str` 作为键。

但是 Pydantic 具有自动转换数据的功能。

这意味着，即使你的 API 客户端只能将字符串作为键发送，只要这些字符串内容仅包含整数，Pydantic 就会对其进行转换并校验。

然后你接收的名为 `weights` 的 `dict` 实际上将具有 `int` 类型的键和 `float` 类型的值。

## 总结

{* ../../docs_src/query_params/tutorial006_py310.py hl[8] *}

In diesem Fall gibt es drei Query-Parameter:

* `needy`, ein erforderlicher `str`.
* `skip`, ein `int` mit einem Defaultwert `0`.
* `limit`, ein optionales `int`.

/// tip | Tipp

Sie können auch `Enum`s verwenden, auf die gleiche Weise wie mit [Pfad-Parametern](path-params.md#predefined-values){.internal-link target=_blank}.

(The #nnnnn suffix must also appear at the end of each line in the file;
that will be preserved when next/*.txt is concatenated into go1.XX.txt.)

When you add a file to the api/next directory, you must add at least one file

from fastapi import FastAPI

app = FastAPI()


@app.post("/index-weights/")
async def create_index_weights(weights: dict[int, float]):

    git config user.email ******@****.***
