Empty oauth parameter is being stripped out, yielding broken signatures

GoogleCodeExporter commented 9 years ago

What steps will reproduce the problem?
1. Send an oauth_token parameter with no value in a GET request and try to 
generate a sig

What is the expected output? What do you see instead?
Expected output is the correct hash, instead I get an incorrect hash 
generated using only a partial parameter set.

Please use labels and text to provide additional information.
This line strips out keys with no values.
parameters = cgi.parse_qs(param_str, keep_blank_values=False)

According to the spec at http://oauth.net/core/1.0/#anchor14 blank values 
are to be preserved when constructing the normalized query string.

What is the reason for keep_blank_values=False? Changing this to True fixed 
all the issues we were having.

By the way, this is for the Python implementation, sorry for omitting that.
