Becase 开发者_开发问答every time you use app, you have to login into offical website.it boring.

This depends on service you are using. For example twitter requres you to use "authentication url" ( https://api.twitter.com/oauth/authenticate ) instead of "authorization url". Facebook uses 2.0 version with javascript so there is not problem with that - you have to include offline_access as permission.

In Google Data API I'm not sure yet.
