Getting all field names from a protocol buffer?

Question

I want to get all the field names of a proto into a list. Is there a way to do this? I looked in the documentation and there doesn\'t seem to be anything for this.

qfiard's answer didn't work for me. Calling message.DESCRIPTOR.fields.keys() produced AttributeError: 'list' object has no attribute 'keys'.

Not sure why it wouldn't work. Maybe it has something to do with how the message was defined/compiled.

The workaround was to do a list composition of the individual field objects and get the name property for each. This gave me a list of strings of all fields in this list.

res = [f.name for f in message.DESCRIPTOR.fields]

Note that this does not get you the field names within those fields recursively.
