Python Script Uploading files via FTP
Question:
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.
Answers:
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.
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.
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"
ftplib now supports context managers so I guess it can be made even easier
from ftplib import FTP
from pathlib import Path
file_path = Path('kitten.jpg')
with FTP('server.address.com', 'USER', 'PWD') as ftp, open(file_path, 'rb') as file:
ftp.storbinary(f'STOR {file_path.name}', file)
No need to close the file or the session
To avoid getting the encryption error you can also try out below commands
ftp = ftplib.FTP_TLS("ftps.dummy.com")
ftp.login("username", "password")
ftp.prot_p()
file = open("filename", "rb")
ftp.storbinary("STOR filename", file)
file.close()
ftp.close()
ftp.prot_p() ensure that your connections are encrypted
