Python Script Uploading files via FTP

问题:

I would like to make a script to upload a file to FTP.

How would the login system work? I'm looking for something like this:

ftp.login=(mylogin)
ftp.pass=(mypass)

And any other sign in credentials.

回答1:

Use ftplib, you can write it like this:

import ftplib
session = ftplib.FTP('server.address.com','USERNAME','PASSWORD')
file = open('kitten.jpg','rb')                  # file to send
session.storbinary('STOR kitten.jpg', file)     # send the file
file.close()                                    # close file and FTP
session.quit()

Use ftplib.FTP_TLS instead if you FTP host requires TLS.

To retrieve it, you can use urllib.retrieve:

import urllib 

urllib.urlretrieve('ftp://server/path/to/file', 'file')

---

EDIT:

To find out the current directory, use FTP.pwd():

FTP.pwd(): Return the pathname of the current directory on the server.

To change the directory, use FTP.cwd(pathname):

FTP.cwd(pathname): Set the current directory on the server.

You will most likely want to use the ftplib module for python

 import ftplib
 ftp = ftplib.FTP()
 host = "ftp.site.uk"
 port = 21
 ftp.connect(host, port)
 print (ftp.getwelcome())
 try:
      print ("Logging in...")
      ftp.login("yourusername", "yourpassword")
 except:
     "failed to login"

This logs you into an FTP server. What you do from there is up to you. Your question doesnt indicate any other operations that really need doing.

I just answered a similar question here IMHO, if your FTP server is able to communicate with Fabric please us Fabric. It is far better than doing raw ftp.

I have an FTP account from dotgeek.com so I am not sure if this will work for other FTP accounts.

#!/usr/bin/python

from fabric.api import run, env, sudo, put

env.user = 'username'
env.hosts = ['ftp_host_name',]     # such as ftp.google.com

def copy():
    # assuming i have wong_8066.zip in the same directory as this script
    put('wong_8066.zip', '/www/public/wong_8066.zip')

save the file as fabfile.py and run fab copy locally.

yeukhon@yeukhon-P5E-VM-DO:~$ fab copy2
[1.ai] Executing task 'copy2'
[1.ai] Login password: 
[1.ai] put: wong_8066.zip -> /www/public/wong_8066.zip

Done.
Disconnecting from 1.ai... done.

Once again, if you don't want to input password all the time, just add

env.password = 'my_password'

Try this:

#!/usr/bin/env python

import os
import paramiko 
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('hostname', username="username", password="password")
sftp = ssh.open_sftp()
localpath = '/home/e100075/python/ss.txt'
remotepath = '/home/developers/screenshots/ss.txt'
sftp.put(localpath, remotepath)
sftp.close()
ssh.close()

You can use the below function. I haven't tested it yet, but it should work fine. Remember the destination is a directory path where as source is complete file path.

import ftplib
import os

def uploadFileFTP(sourceFilePath, destinationDirectory, server, username, password):
    myFTP = ftplib.FTP(server, username, password)
    if destinationDirectory in [name for name, data in list(remote.mlsd())]:
        print "Destination Directory does not exist. Creating it first"
        myFTP.mkd(destinationDirectory)
    # Changing Working Directory
    myFTP.cwd(destinationDirectory)
    if os.path.isfile(sourceFilePath):
        fh = open(sourceFilePath, 'rb')
        myFTP.storbinary('STOR %s' % f, fh)
        fh.close()
    else:
        print "Source File does not exist"
