putItem() yields invalid signature when character '!' is present in value

[arturadib]

The following code makes Amazon respond with HTTP 403 and error code "SignatureDoesNotMatch":

var simpledb = require('simpledb');

sdb = new simpledb.SimpleDB({keyid:'...', secret:'...'});
sdb.putItem('test', 'item01', {my_key:'this character will break the request: !'}, function(err){
  if (err) throw err.Message;
});

When I remove the exclamation mark from the item no error is returned.

I believe this would be fixed by this pull request on the aws-lib library. I have a similar issue with other characters.

[arturadib]

Yep. Someone made a pull request to another fork of aws-lib too:

https://github.com/mirkok/aws-lib/pull/1

What other characters are you having trouble with?

[crcastle]

oops, sorry. I meant to say I had a similar issue. @mirkok fixed it with my pull request several months ago (livelycode/aws-lib@c8030cc). guess i missed this character. thanks guys.

Hi Guys - yes this looks like an aws-lib signing issue similar to the previous one.

Can the fix be brought into the main code base? I just installed the module and ran into this problem -- took me quite a while to single out the cause.
