描述

I'm trying to export REST APIs and the problem is that in my PUT request, client usually tries to pass only fields to update, but the generated proto will set all the other fields to its default value. I have no way to tell which fields to update.

Of course I can restrict client to always pass the full object, but is there better way to do this?

研究方向
Investigate how the grpc gateway currently handles PUT requests and partial updates. Look at the generated proxy code and consider options like using field masks or requiring full object. Review comments in issue #379 for proposed solutions and constraints. The goal is to define a clear design that allows clients to send only fields to update without resetting defaults.
