Name or service not known error in EasyWebDav for Python

Question

I'm trying to setup a WebDAV connection using easywebdav in Python. (Using 2.7.8 for now)

import csv, easywebdav

webdav=easywebdav.connect('https://sakai.rutgers.edu/dav/restoftheurl,username="",password="")
print webdav.ls()

Though when I run this I get the following error message. My guess is that it possibly has something to do with the URL using HTTPS?

Traceback (most recent call last):

Answer 1

I find it strange that you combine HTTPS protocol and port 80. HTTPS uses port 443.

Though the error message "Name or service not known" would rather indicate that the hostname sakai.rutgers.edu is not recognized on your system. Try to ping the host.

Answer 2

I noticed that you shouldn't have http:// or https:// in the beginning of your adress, only the host name. You select protocol with protocol='https'. Also, I couln't get it to work if I added the path the url, I had to use it as argument to the operations like easywebdav.ls('/dav/restoftheurl') or easywebdav.cd('/dav/restoftheurl').
