Вы также можете использовать `from starlette.responses import Response` или `from starlette.responses import JSONResponse`.

调用它的结果后就可以使用Python标准编码中的<a href="https://docs.python.org/3/library/json.html#json.dumps" class="external-link" target="_blank">`json.dumps()`</a>。

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

`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。

- [ ] Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
- [ ] Each commit in the pull request should have a meaningful subject line and body.
  Note that commits might be squashed by a maintainer on merge.
- [ ] Write unit tests that match behavioral changes, where the tests fail if the changes to the runtime are not applied.
  This may not always be possible but is a best-practice.
