tornado.httputil.HTTPServerRequest and tornado.web.RequestHandler

[Stronking]

In the tornado.httputil.HTTPServerRequest class, why is the body_arguments attribute initialized as an empty dictionary {}? This design choice necessitates developers to manually parse the request.body when handling POST request bodies, and it precludes the use of parameter assertions. Consequently, when utilizing the tornado.web.RequestHandler.get_body_arguments methods, a MissingArgumentError is consistently thrown if the corresponding parameter is missing from the request body. Will this issue be addressed or improved in future versions?

This problem can hinder user experience and code robustness, especially for developers who are new to the Tornado framework. It may increase the difficulty of understanding and using the framework. It would be appreciated if the development team could consider optimizing this issue or providing clearer documentation on how to handle it.
