在这个例子中，它将Pydantic模型转换为`dict`，并将`datetime`转换为`str`。

调用它的结果后就可以使用Python标准编码中的[`json.dumps()`](https://docs.python.org/3/library/json.html#json.dumps)。

这个操作不会返回一个包含JSON格式（作为字符串）数据的庞大的`str`。它将返回一个Python标准数据结构（例如`dict`），其值和子值都与JSON兼容。

/// note | 注意

`jsonable_encoder`实际上是**FastAPI**内部用来转换数据的。但是它在许多其他场景中也很有用。
