del.icio.us API parameter values with spaces

[floehopper]

I've successfully got OAuth working with the del.icio.us API, but it doesn't seem to work when I have parameters including spaces.

This works :-

url = "http://api.del.icio.us/v2/posts/get?tag=ruby"
puts access_token.get(url).body

But this fails with a "signature_invalid" error :-

url = "http://api.del.icio.us/v2/posts/get?tag=ruby+oauth"
puts access_token.get(url).body

I'll try and narrow this down further, but I'd be grateful if you could tell me whether there is anything obvious I might be doing wrong.

Thanks, James.

I think I've worked it out. It looks like OAuth gem is escaping a space character as "%20" when generating the signature. But I was escaping a space character as "+" and this seems to upset the signature checking. Cheers, James.
