downloading file using ftp - python

I am writing a python script to get logged in using ftp and download a file.But whenever I run this script,it says I have provided wrong user name or passwd.I am inputting right password still i am unable to run this script.My code is:
import os,getpass
from urllib.request import urlopen
filename='68544.jpg'
password=getpass.getpass('??')
At this line below the script is failed to run and whenever i run this address in browser it runs fine.
remoteaddr='ftp://Kamal:%s#localhost/%s;type=i'%(password,filename)
remotefile=urlopen(remoteaddr)
localfile=open(filename,'wb')
localfile.write(remotefile.read())
localfile.close()
remotefile.close()

def ftp_connect(path):
link = FTP(host = 'example.com', timeout = 5) #Keep low timeout
link.login(passwd = 'ftppass', user = 'ftpuser')
debug("%s - Connected to FTP" % strftime("%d-%m-%Y %H.%M"))
link.cwd(path)
return link
downloaded = open('/local/path/to/file.tgz', 'wb')
def debug(txt):
print txt
link = ftp_connect(path)
file_size = link.size(filename)
max_attempts = 5 #I dont want death loops.
while file_size != downloaded.tell():
try:
debug("%s while > try, run retrbinary\n" % strftime("%d-%m-%Y %H.%M"))
if downloaded.tell() != 0:
link.retrbinary('RETR ' + filename, downloaded.write, downloaded.tell())
else:
link.retrbinary('RETR ' + filename, downloaded.write)
except Exception as myerror:
if max_attempts != 0:
debug("%s while > except, something going wrong: %s\n \tfile lenght is: %i > %i\n"(strftime("%d-%m-%Y %H.%M"), myerror, file_size, downloaded.tell()))
link = ftp_connect(path)
max_attempts -= 1
else:
break
debug("Done with file, attempt to download m5dsum")

Use Paramiko library
import paramiko
paramiko.util.log_to_file('/tmp/paramiko.log')
# Open a transport
host = "example.com"
port = 22
transport = paramiko.Transport((host, port))
# Auth
password = "foo"
username = "bar"
transport.connect(username = username, password = password)
# Go!
sftp = paramiko.SFTPClient.from_transport(transport)
# Download
### It is relative path from the folder path on which this sftp user has default rights.
filepath = 'folder/file1.txt'
localpath = '/opt/backup/file.txt'
sftp.get(filepath, localpath)
# Close
sftp.close()

Python Sockets: my recv protocol receive all the data when i debug it but not when i run it doesnt

So my project is that I need to send a jpg image from one computer to another computer in the same network. To send the data I split the data into chunks of at least 9999 bytes and then I create a length header that tells the length of the data and I attach it to the start of the massage. here is the code:
the protocol:
import os.path
LENGTH_FIELD_SIZE = 4
PORT = 8820
COMANDS_LIST = "TAKE_SCREENSHOT\nSEND_PHOTO\nDIR\nDELETE\nCOPY\nEXECUTE\nEXIT".split("\n")
def check_cmd(data):
"""
Check if the command is defined in the protocol, including all parameters
For example, DELETE c:\work\file.txt is good, but DELETE alone is not
"""
command = ""
file_location =""
splited_data = data.split(maxsplit=1)
if len(splited_data) == 2:
command, file_location = splited_data
return (command in COMANDS_LIST) and (file_location is not None)
elif len(splited_data) == 1:
command = splited_data[0]
return command in ["TAKE_SCREENSHOT","EXIT","SEND_PHOTO"]
return False
# (3)
def create_msg(data):
"""
Create a valid protocol message, with length field
"""
data_len = len(str(data))
if data_len > 9999 or data_len == 0:
print(f"data len is bigger then 9999 or is 0, data len = {data_len} ")
return False
len_field = str(data_len).zfill(4)
# (4)
print(len_field)
return True ,f"{len_field}{data}"
def get_msg(my_socket):
"""
Extract message from protocol, without the length field
If length field does not include a number, returns False, "Error"
"""
lenght_field = ""
data = ""
try:
while len(lenght_field) < 4:
lenght_field += my_socket.recv(4).decode()
except RuntimeError as exc_run:
return False, "header wasnt sent properly"
if not lenght_field.isdigit():
return False, "error, length header is not valid"
lenght_field = lenght_field.lstrip("0")
while len(data) < int(lenght_field):
data += my_socket.recv(int(lenght_field)).decode()
return True, data
now the protocol works fine when I use the same computer for both server and client and when I debug get_msg on the other computer. when I'm not, it seems that the problem is that the part that recv the header will recv something else after a few successful recv and return an error message.

here is how the problem looks like:thi is how it looks
here is how to needs look like:
the right way
thank you.
the solution was to change get_msg function in the protocol:
while len(data) < int(lenght_field):
data += my_socket.recv(int(lenght_field) - len(data)).decode()
instead of:
while len(data) < int(lenght_field):
data += my_socket.recv(int(lenght_field)).decode()

Don't know how to execute function after else command

I'm trying to take an image via webcam then send the image through gmail. That function suppose to happen if my fingerprint is known at the system. If it does it needs to execute the send email function. I added after the send email function to send 'HIGH' to a gpio. I don't think it suppose to interfere.
When there is a known template it is followed by an "else:" statement. then I put my "def find_newest_file(dir):" function. What am I doing wrong?
might note I'm terrible at programming. Thank you!

You need to define the function at the top of the program. You only need to call it after the else statement. Basically, put
def find_newest_file(dir):
os.system('fswebcam -r 1280x720 -S 3 --jpeg 90 --save /home/pi/Pictures/%H%M%S.jpg')
types = ['*.png', '*.jpg']
files = []
if not os.path.isdir(dir):
print(f'ERROR: {dir} does not exist. or it is not a valid folder')
exit()
at the top and when you want to use it do
find_newest_file(foo)
Good luck on your journey!

Cannot connect to imap server on python

I'm a networking student who has little programming experience and I have simple project on my hands where I need to make a simple notification that notifies the user when an email arrives in gmail. I have been trying to get this to work for the last few weeks and I am honestly stuck and struggling. I'm using the code below and I think the problem is the authentication bit, where I can't connect to the server. All help is appreciated.
import imaplib
import re
import time
import subprocess
## enter your account details bellow!
imapServer = "imap.gmail.com"
port = "993"
username = "example#gmail.com"
password = "password"
##how often to check ? give interval in seconds! Checking too often might performance and stability.
checkInterval = 120
Mailbox = imaplib.IMAP4_SSL(imapServer, port)
rc,resp = Mailbox.login(username,password)
if rc == 'OK':
print("Connected to mail-server " + imapServer)
rc, message = Mailbox.status('INBOX', "(UNSEEN)")
unreadCount = int(re.search("UNSEEN (\d+)",str( message[0])).group(1))
oldValue = 0
file = open("%sytemdrive%\Windows\Temp\mailnotify.tmp", "w+")
file.write(str(unreadCount))
file.close
while(1):
rc, message = Mailbox.status('INBOX', "(UNSEEN)")
unreadCount = int(re.search("UNSEEN (\d+)",str( message[0])).group(1))
file = open("%sytemdrive%\Windows\Temp\mailnotify.tmp", "w+")
oldValue = int(file.readline())
file.close()
if (unreadCount>oldValue):
subprocess.call(["notify-send", "-u", "low", "low", "t", "5000", "New email!", "New email!",
"You have " + str(unreadCount) + " unread " + "emails!" if unreadCount > 1 else "email!",
"--icon=email"])
if oldValue != unreadCount:
file = open("%sytemdrive%\Windows\Temp\mailnotify.tmp", "w+")
file.write(str(unreadCount))
file.close()
time.sleep(checkInterval)
else :
print('Fail to connect')
Mailbox.logout()
file.remove()

Upload folders from local system to FTP using Python script

I have to automatically upload folders to an FTP using a Python script. I am able to upload a single file, but not folders with subfolders and files in them. I did a lot of search, but failed. Could some one help me out here? Thanks in advance.
#! /usr/bin/python
import ftplib
s = ftplib.FTP('serverip','usrname','password')
file = '/home/rock/test.txt'
ftppath = '/IT'
filename = "rak"
s.cwd(ftppath)
f = open(file,'rb')
s.storbinary('STOR ' + filename, f)
f.close()
s.quit()
I recently came into this problem and figured out a recursive function to solve it.
import ftplib
import os
server = 'localhost'
username = 'generic_user'
password = 'password'
myFTP = ftplib.FTP(server, username, password)
myPath = r'c:\temp'
def uploadThis(path):
files = os.listdir(path)
os.chdir(path)
for f in files:
if os.path.isfile(path + r'\{}'.format(f)):
fh = open(f, 'rb')
myFTP.storbinary('STOR %s' % f, fh)
fh.close()
elif os.path.isdir(path + r'\{}'.format(f)):
myFTP.mkd(f)
myFTP.cwd(f)
uploadThis(path + r'\{}'.format(f))
myFTP.cwd('..')
os.chdir('..')
uploadThis(myPath) # now call the recursive function
You basically need to use os.walk() to grab those files and transfer them.
Here's a script I wrote for myself to do much of what your asking.
I wrote it a long time ago, so I'd probably do it differently if I wrote it again, but I get a lot of use out of it.
It imports psftplib, which is a wrapper I wrote for the putty sftp.
Feel free to remove these references, or grab the lib at:

EDIT 20/12/2017:
I have written a project in GitHub for this purpose. Click for details!
There are good answers above but i also want to add a good one using ftputil package. If you need to upload files from local directory to ftp directory, you can use this recursive function:
def upload_dir(localDir, ftpDir):
list = os.listdir(localDir)
for fname in list:
if os.path.isdir(localDir + fname):
if(ftp_host.path.exists(ftpDir + fname) != True):
ftp_host.mkdir(ftpDir + fname)
print(ftpDir + fname + " is created.")
upload_dir(localDir + fname + "/", ftpDir + fname + "/")
else:
if(ftp_host.upload_if_newer(localDir + fname, ftpDir + fname)):
print(ftpDir + fname + " is uploaded.")
else:
print(localDir + fname + " has already been uploaded.")
If you decide to use this function, you have to connect ftp using ftputil package. For this, you can use this snippet:
with ftputil.FTPHost("ftp_host", "ftp_username", "ftp_password") as ftp_host:
So, we're almost done. The last thing is usage of the function for beginners like me:
local_dir = "D:/Projects/.../"
ftp_dir = "/.../../"
upload_dir(local_dir, ftp_dir)
The most important thing is "/" character at the end of paths. You need to put it at the end. Finally, i want to share entire code:
with ftputil.FTPHost("ftp_host", "ftp_username", "ftp_password") as ftp_host:
def upload_dir(localDir, ftpDir):
list = os.listdir(localDir)
for fname in list:
if os.path.isdir(localDir + fname):
if(ftp_host.path.exists(ftpDir + fname) != True):
ftp_host.mkdir(ftpDir + fname)
print(ftpDir + fname + " is created.")
upload_dir(localDir + fname + "/", ftpDir + fname + "/")
else:
if(ftp_host.upload_if_newer(localDir + fname, ftpDir + fname)):
print(ftpDir + fname + " is uploaded.")
else:
print(localDir + fname + " has already been uploaded.")
local_dir = "D:/Projects/.../"
ftp_dir = "/.../../"
upload_dir(local_dir, ftp_dir)
Maybe you try ftpsync.py. If this one doesn't helps, try google search on python ftpsync and you get a lot of answers.
using ftputil:
import os
import ftputil
import ftputil.session
def upload_dir(root):
root = unicode(root, 'utf-8')
for dir_name, _, dir_files in os.walk(root):
local = os.path.join(os.curdir, dir_name)
remote = ftp_host.path.join(ftp_host.curdir, dir_name)
if not ftp_host.path.exists(remote):
print 'mkdir:', local, '->', remote
ftp_host.mkdir(remote)
for f in dir_files:
local_f = os.path.join(local, f)
remote_f = ftp_host.path.join(remote, f)
print 'upload:', local_f, '->', remote_f
ftp_host.upload(local_f, remote_f)
sf = ftputil.session.session_factory(use_passive_mode=True)
with ftputil.FTPHost('HOST', 'USER', 'PASS', session_factory=sf) as ftp_host:
upload_dir('DIR')
It is easy to use lftp to upload folders to an FTP. I use this in my Python script to move folders to FTP
Python script:
#! /usr/bin/python
import subprocess
subprocess.call(["bash", ftp_script, username, password, ftp, folder_to_move, src,folder_name_in_destination])
ftp_script:
lftp -u $1,$2 $3 <<EOF
mkdir $4
lcd $5
cd $6
mirror --reverse
EOF
Yet another answer using ftputil. And pathlib for figuring out the local path.
I've compiled and improved some of the above answers.
So thank you for the inspiration!
import os
import ftplib
import ftputil
from pathlib import Path
def ftp_upload(ftp_host, src_path, dst_path=None):
if dst_path is None:
ftp_host.path.join(os.curdir)
# Make sure that local path is a directory
if src_path.is_dir():
# Make sure that the root path exists
if ftp_host.path.exists(dst_path) is False:
# Inform user
print(f'mkdir: {src_path} -> {dst_path}')
# Create folder
ftp_host.mkdir(dst_path)
# Parse content of the root folder
for src_child in src_path.iterdir():
if src_child.is_dir():
# Use recursion for sub folders/files
dst_child = ftp_host.path.join(dst_path, src_child.stem)
ftp_upload(ftp_host, src_child, dst_child)
else:
# Copy sub files
dst_child = ftp_host.path.join(dst_path, src_child.name)
# Inform user
print(f'upload: {src_child} -> {dst_child}')
# Perform copy (upload)
ftp_host.upload(src_child, dst_child)
# ftp_host.upload_if_newer(src_child, dst_child)
else:
# Inform user
print(f"src_path: '{src_path}' must be an existing directory!")
if __name__ == '__main__':
# FTP settings
user = "ftp_user"
password = "ftp_password"
host = "localhost"
port = 2121
# Path settings
src_path = Path(__file__).parent.resolve() / "upload_dir"
dst_dir = "upload_dir"
# Inform user
print(f"Establishing FTP session as '{user}'")
# Establish FTP session
ftplib.FTP.port = port
with ftputil.FTPHost(host, user, password) as ftp_host:
# Perform recursive FTP upload
dst_path = ftp_host.path.join(os.curdir, dst_dir)
ftp_upload(ftp_host, src_path, dst_path)
