weibo oauth2: http://open.weibo.com/wiki/Oauth2

This is very trivial testing of the httpclient api.
1. this case will print out a URL
2. run the URL in browser and will navigate to weibo auth page
3. conform the authentication and browser will navigate back to the callback url,
   which obviously will failed cause there is no local server.
4. copy the `code` in the callback url and parse into console
5. this test case will gain access token using the `code` and print it out.

check for integration testing at:
