Error on performing file operations

[arwankhoiruddin]

Hi,

I exactly followed your guide to connect to my webdav server. Here is my code

import easywebdav

webdav = easywebdav.connect('http://my-server.com/remote.php/webdav/',username='my-username',password='my-password')

I did not have problem so far.

However, when I add another line of code, for example webdav.ls() or webdav.mkdir('adirectory'), it gives me the following error.

Traceback (most recent call last):
  File "/Users/arwankhoiruddin/Documents/sss/coba.py", line 6, in <module>
    webdav.mkdir("easywebdav")
  File "/Users/arwankhoiruddin/scram/lib/python2.7/site-packages/easywebdav/client.py", line 123, in mkdir

    r = adapter.send(request, **kwargs)

    raise ConnectionError(e, request=request)

Please suggest. Thanks

I see that you were on owncloud. I just tested this out on nextcloud's demo server with success:

>>> webdav = easywebdav.connect('demo.nextcloud.com', username='admin', password='admin', protocol='https', port=443, path='/xee8uy5p/remote.php/webdav/')
>>> webdav.delete('Nextcloud.mp4')

Hope this helps a year later ;)

Despite the above, I'm having difficulties with it on my own nextcloud server. I'm going to guess it has something to do with my nginx configuration... but curl works just fine.

>>> webdav.ls()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.6/site-packages/easywebdav/client.py", line 184, in ls
    return [elem2file(elem) for elem in tree.findall('{DAV:}response')]
  File "/usr/lib/python3.6/site-packages/easywebdav/client.py", line 184, in <listcomp>
    return [elem2file(elem) for elem in tree.findall('{DAV:}response')]
  File "/usr/lib/python3.6/site-packages/easywebdav/client.py", line 40, in elem2file
    int(prop(elem, 'getcontentlength', 0)),
TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'

That's if I specify path='blah'. If I just append the path to the host (.e.g. myserver.com/remote.php/webdav/), then I get:

>>> webdav.ls()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

Hey All!

Both of you are correct.

webdav = easywebdav.connect(
    'demo.nextcloud.com',
    username='admin',
    password='admin',
    protocol='https',
    port=443,
    path='/eeb3giep/remote.php/webdav/')
webdav.delete('Nextcloud.mp4') # delete works
webdav.ls() # ls --> results in errors @ghost reported

My solution is --> go into client.py and replace elem2file with:

def elem2file(elem):
    try:
        return File(
            prop(elem, 'href'),
            int(prop(elem, 'getcontentlength', 0)),
            prop(elem, 'getlastmodified', ''),
            prop(elem, 'creationdate', ''),
            prop(elem, 'getcontenttype', ''),
        )
    except:
        return File(
            prop(elem, 'href'),
            0,
            prop(elem, 'getlastmodified', ''),
            prop(elem, 'creationdate', ''),
            prop(elem, 'getcontenttype', ''),
        )

try:
return File(
prop(elem, 'href'),
int(prop(elem, 'getcontentlength', 0)),
prop(elem, 'getlastmodified', ''),
prop(elem, 'creationdate', ''),
prop(elem, 'getcontenttype', ''),
)
except:
return File(
prop(elem, 'href'),
0,
prop(elem, 'getlastmodified', ''),
prop(elem, 'creationdate', ''),
prop(elem, 'getcontenttype', ''),
)

This works for me too.
