What steps will reproduce the problem? 1. Use scope https://www.googleapis.com/auth/userinfo#email to retrieve user email account 2. URL component delimiter # character in this scope is not encoded by URL.encode and cause whatever after # to be discarded

What is the expected output? What do you see instead? error: invalid_request: Missing required parameter: redirect_uri

Please provide any additional information below.

URL.encodeQueryString may fix issue.

So, what is that scope URL? Are you sure that's an OAuth 2.0 scope?

Secondly, you're right, this should work with that string, if it is an OAuth 2.0 scope. The spec doesn't specify valid/invalid characters in a scope, so we'll have to assume anything can work.

Currently the necessary URL encoding is done with URL.encode/decode, it sounds like it needs to be encodeQueryString/decodeQueryString as you suggest.

I'll submit a fix soon and potentially cut a new release this week.

The scope and description can be found at http://sites.google.com/site/oauthgoog/Home/emaildisplayscope

It's a scope to get logged in user's email. Not sure how to find out if it is a oauth 2.0 scope
