tqsdk程序交易过程中经常会出现以下错误提示：

Missing return statement on request handler
Traceback (most recent call last):
File “D:\Python313\Lib\site-packages\aiohttp\web_protocol.py”, line 653, in finish_response
prepare_meth = resp.prepare
^^^^^^^^^^^^
AttributeError: ‘NoneType’ object has no attribute ‘prepare’

望能改进！
