FTPing OUT of Zope

Category: Python(External Method)

#create file on filesystem in $ZOPE/Extensions called ftpme.py
import ftplib
from string import split
from StringIO import StringIO

host='localhost'

password='^%$^@5@#$S'
port=21

    _ftp = ftplib.FTP()
    _ftp.connect(host, port)
    _ftp.login(login, password)

        binary=1

        ftp_file(_ftp, obj, binary)

    if lower(obj.meta_type)=='image':
        ftp_file(_ftp, obj, 1)

    _ftp.quit()

    if binary:
        ftpCon.storbinary("STOR " + fileObj.getId(), StringIO(fileObj.data), 1024)
    else:
        f = StringIO()
        f.readlines(split(fileObj.data, '\n'))

        ftpCon.storlines("STOR " + fileObj.getId(), f)

#create a External Method in ZOPE, called ftp_out
#id: ftp_out, module name: ftpme, function: ftp

#now to use this external method from a Script(Python) its very simple
#create a Script (Python) called ftp_doer

file=getattr(context, 'index.html')
context.ftp_out(file)

#in DTML
<dtml-call "ftp_out(_.getitem('index.html'))">

#or if you wanted to pass host/login info you can from script
#to port 8021
context.ftp_out(file, 'ftp.python.org', 'anonymous', 'bob@slack.net', 8021)
