Get "Method Not Allowed" when trying to fetch csv from URL

Hi,

Im trying to fetch the following csv file into my algo:

csv_file= http://annfetcher.appspot.com/test.csv

with this code:

fetch_csv(csv_file, pre_func=preview, post_func=preview, date_column='date', date_format='%m/%d/%y', universe_func=my_universe)

When I run it I get the following error message:

"Error loading csv data from http://annfetcher.appspot.com/test.csv: 405 - Method Not Allowed"

the code works fine if i try fetching the csv from Dropbox.

Is there anything i am doing wrong, or can do in another way to fetch the file?

Hi Erik,

Fetcher requires the url to support GET and HEAD requests. Based on the url you are testing, looks like you are providing a service from app engine (super cool). That means you'll need to implement GET and HEAD in your service. Since retrieving the document in the browser works, the problem must be that HEAD is not implemented for the service.

thanks,
fawce
