How to access Google feeds(Reader) with OAuth2.0?

问题

I want to access google feeds with OAuth2.0. I used google-oauth-java-client to get my access token. How can I use it to access the feeds API?

I referenced dailymotion-cmdline-sample, and changed SCOPE as http://www.google.com/reader/api to fetch the credential.

It returns:

401 Unauthorized

You must be signed in to access this stream.

And I don't know what's wrong...

I also read some posts which shows OAuth2.0 is possible to do this job, but they are not detailed enough to me:

Read access only for the Google OAuth 2.0 token?

Using the Google Reader API

Accessing Google Reader subscriptions with OAuth2 access_token

I had the same problem with the scope as http://www.google.com/reader/api/*. I solved it by changing the scope to http://www.google.com/reader/api/. Try with the / at the end.
