Sorry that I am really, really new to Python but I have run into a wall and=
need some help:
Basically, I am trying to create a web-client for a sftp server.
You enter your user name and password and you authenticate against the sftp=
server, see a list of all the files on the server, can browse the server, =
and if you click on a link download the file.
I have tried several different methods to keep the network-resource in the =
session, but nothing thus far has worked. My research seems to indicate tha=
t in order to achieve this I would need to write a daemon that handles the =
connection, and pass the session id to the daemon to match connection to we=
b request.
I have found some articles on how to turn a python script into a daemon, bu=
t I need some help understanding what is really going.
Anyways, the script I have tested thus far using mod_python is below:
from mod_python import apache
from mod_python import Session
import paramiko
def handler(req):
session=3DSession.Session(req)
req.content_type=3D"text/html"
try:
session['hits'] +=3D1
#dirlist=3Dsession['sftp'].listdir('.')
req.write('From Session')
except:
t=3Dparamiko.Transport(('[SERVER NAME],22))
t.connect(username=3D'[USER NAME]',password=3D'[PASSWORD]')
sftp=3Dparamiko.SFTPClient.from_transport(t)
dirlist =3D sftp.listdir('.')
session['hits']=3D1
session['sftp']=3Dsftp
req.write('New Session')
session.save()
req.write('Hits %d\n' % session['hits'])
req.write(dirlist)
return apache.OK
