Upload file to FTP using Python ftplib

JessicaKirby

Hello Pythoners,
I have exhausted myself searching for code that will do what I need, so I am hoping that someone here has my answer.

I need to automate a monthly upload cycle of maps to our FTP server.  Below is what I have attempted to patchwork together, but it will not work.  I am very new to python so please forgive any gross errors in this code.  Also,  the code is set up to send only one file as a test, but the end code needs to loop through a directory and transfer 29 maps, while overwriting the existing maps on the ftp server. 

import ftplib
from ftplib import FTP

File2Send = "V://GIS//Maps//County//11x17shd//2010BEAVER11x17shd.pdf"
Output_Directory = "//data2//ftp//pub//download//maps//"

try:
    ftp = FTP("xyz.xyz.xyz.xyz")
    ftp.login(username, password)
    file = open(File2Send, "rb")
    ftp.cwd(Output_Directory)
    ftp.storbinary('STOR ' + File2Send, file)
    print "STORing File now..."
    ftp.quit()
    file.close()
    print "File transfered"
else:
    print "An error occured"

If you want to discuss this further, just post your e-mail. 🙂

I'm interested.  huffmanp@ykfp.org.  I have been trying to keep an ftp site in sync with a linux website directory and I've been going about this very inefficiently, partly because few feature requests keep being added on. I wrote a little perl script a few years ago to give users a form to upload files to a directory on the web site.  Recently I was asked if I could write a version of the script to allow uploads for a new project to a new directory, and also push these files out to an ftp account on the hosting company, so the users of this data could access the ftp directory without needing the username, password of the website and have these users pawing through all the directories on the web site to find the one they are supposed to be accessing. 

The most logical thing for me to do would be to modify the perl script to push a copy of any file uploaded to the ftp site also.  But I looked at the perl script and though "Cripes, I've forgotten everything I ever knew about perl."  I looked at Uber-Uploader since it's written in php which I can manage a bit better and has a perl component so the upload file size can be larger than with php without fiddling with php.ini settings.  But I couldn't get Uber-Uploader to run on my host.  Then I started looking at python ways to do it since I need to get better with python. 

I got python to work for me thusly:

import ftplib
import os
import sys
import traceback

print "Logging in..."
ftp = ftplib.FTP()
ftp.connect('ftphostname')
print ftp.getwelcome()
try:
    try:
        ftp.login('username', 'password')
        ftp.cwd('target directory')
        # move to the desired upload directory
        print "Currently in:", ftp.pwd()

        print "Uploading...",
        fullname = '../sourcedirectoy/filename'
        name = os.path.split(fullname)[1]
        f = open(fullname, "rb")
        ftp.storbinary('STOR ' + name, f)
        f.close()
        print "OK"
        
        print "Files:"
        print ftp.retrlines('LIST')
    finally:
        print "Quitting..."
        ftp.quit()
except:
    traceback.print_exc()

But now I'll have to see if I can make it work on a whole directory.  If I were clever, I'd run this python script every few hours as a cron job (in windows, a "scheduled task"), and test the source directory for any file newer than last time the script ran in a cron.  If I were really clever, I'd just add the ftp push to my original perl script.
