Redirection to the authorization server fails in calendar web server example

[GoogleCodeExporter]

Attempt to run the "Authorized API for web application example" in "Getting 
Started" leads to redirection error during oauth2 authentication.

Steps to reproduce the problem:
1. Set up a project exactly according to the instructions of "Setup for 
example". Specifically, edit the Redirect URIs field to http://localhost:8080 
as instructed.
2. Download the example code authorized_api_web_server_calendar.py
3. Run the example exactly as "Run the example" instructs, with the command 
line:
$ python authorized_api_web_server_calendar.py your_client_id 
your_client_secret.

The expected output for the first run is redirection to the authorization 
server when a url request to http://localhost:8080/?fake_user=joe is entered 
from a browser.

Instead, an error page shows up with Error: redirect_uri_mismatch.

The problem can be solved by removing the appending slash in line 39 of the 
python code:
redirect_uri='http://localhost:8080/')
=>
redirect_uri='http://localhost:8080')
