Failed to load resource: the server responded with a status of 405 (Method Not Allowed) ?

I have create my client id (include Books and Contacts API, InitPoint = http://127.0.0.1:3030), and modify "oauth_example.dart" as the following code. But I got error message:
Failed to load resource: the server responded with a status of 405 (Method Not Allowed)
https://www.google.com/m8/feeds/contacts/default/full

I don't have the bandwidth to track this issue at the moment. The Access-Control-Allow-Origin are tricky, I've not been able to figure out why some APIs throw this error and others do not. Maybe something like http://progrium.com/localtunnel/ would aid in development?
