I'm trying to retrieve a zip folder(s) from an ftp site and save them to my local machine, using python (ideally I'd like to specify where they are saved on my C:).
The code below connects to the FTP site and then *something happens in the PyScripter window that looks like random characters for about 1000 lines... but nothing actually gets downloaded to my hard drive.
Any tips?
import ftplib
import sys
def gettext(ftp, filename, outfile=None):
# fetch a text file
if outfile is None:
outfile = sys.stdout
# use a lambda to add newlines to the lines read from the server
ftp.retrlines("RETR " + filename, lambda s, w=outfile.write: w(s+"\n"))
def getbinary(ftp, filename, outfile=None):
# fetch a binary file
if outfile is None:
outfile = sys.stdout
ftp.retrbinary("RETR " + filename, outfile.write)
ftp = ftplib.FTP("FTP IP Address")
ftp.login("username", "password")
ftp.cwd("/MCPA")
#gettext(ftp, "subbdy.zip")
getbinary(ftp, "subbdy.zip")
Well, it seems that you simply forgot to open the file you want to write into.
Something like:
getbinary(ftp, "subbdy.zip", open(r'C:\Path\to\subbdy.zip', 'wb'))

I think my question sounds kinda stupid but I'm pretty new to python programming.
I just want to have a text variable which gets a string from a .txt file at an FTP server.
So in conclusion: There is a .txt File stored at an FTP server and I want to have the content of this file stored in an variable...
This is what I have so far... Can anybody help me? I use Python 3.6.3 :) thanks in advance!
from ftplib import FTP
ftp = FTP('1bk2t.ddns.net')
ftp.login(user='User', passwd = 'Password')
ftp.cwd('/path/')
filename = 'filename.txt'
ftp.retrbinary("RETR " + filename, open(filename, 'wb').write)
ftp.quit()
var = localfile.read
If you want to download a text file contents to memory, without using any temporary file, use FTP.retrlines like:
contents = ""
def collectLines(s):
global contents
contents += s + "\n"
ftp.retrlines("RETR " + filename, collectLines)
Or use an array:
lines = []
ftp.retrlines("RETR " + filename, lines.append)
You can use StringIO as buffer for retrlines RETR:
import io
with io.StringIO() as buffer_io:
ftp.retrlines(f'RETR {filename}', buffer_io.write)
content = buffer_io.getvalue()
I’m having a hard time with this simple script. It’s giving me an error of file or directory not found but the file is there. Script below I’ve masked user and pass plus FTP site
Here is my script
from ftplib import FTP
ftp = FTP('ftp.domain.ca')
pas = str('PASSWORD')
ftp.login(user = 'user', passwd=pas)
ftp.cwd('/public_html/')
filepaths = open('errorstest.csv', 'rb')
for j in filepaths:
print(j)
ftp.delete(str(j))
ftp.quit()
The funny thing tho is if I slight change the script to have ftp.delete() it finds the file and deletes it. So modified to be like this:
from ftplib import FTP
ftp = FTP('ftp.domain.ca')
pas = str('PASSWORD')
ftp.login(user = 'user', passwd=pas)
ftp.cwd('/public_html/')
ftp.delete(<file path>)
ftp.quit()
I’m trying to read this from a csv file. What am I doing wrong?
Whatever you have showed seems to be fine. But could you try this?
from ftplib import FTP
ftp = FTP(host)
ftp.login(username, password)
ftp.cwd('/public_html/')
print(ftp.pwd())
print(ftp.nlst())
with open('errorstest.csv') as file:
for line in file:
if line.strip():
ftp.delete(line.strip())
print(ftp.nlst())
I have tried the following code by slightly modifying the example in documentation
class Upload():
def POST(self):
web.header('enctype','multipart/form-data')
print strftime("%Y-%m-%d %H:%M:%S", gmtime())
x = web.input(file={})
filedir = '/DiginUploads' # change this to the directory you want to store the file in.
if 'file' in x: # to check if the file-object is created
filepath=x.file.filename.replace('\\','/') # replaces the windows-style slashes with linux ones.
filename=filepath.split('/')[-1] # splits the and chooses the last part (the filename with extension)
fout = open(filedir +'/'+ filename,'w') # creates the file where the uploaded file should be stored
fout.write(x.file.file.read()) # writes the uploaded file to the newly created file.
fout.close() # closes the file, upload complete.
But this works only for csv and txt documents. For Excel/pdf etc file gets created but it can't be opened (corrupted). What should I do to handle this scenario?
I saw this but it is about printing the content which does not address my matter.
You need to use wb (binary) mode when opening the file:
fout = open(filedir +'/'+ filename, 'wb')
I am trying to perform a task to transfer files between two different FTP locations. And the simple goal is that I would want to specific file type from FTP Location A to FTP Location B for only last few hours using Python script.
I am using ftplib to perform the task and have put together below code.
So far the file transfer is working fine for single file defined in the from_sock variable, but I am hitting road block when I am wanting to loop through all files which were created within last 2 hours and copy them. So the script I have written is basically copying individual file but I want to I wan't to move all files with particular extension example *.jpg which were created within last 2 hours. I tired to use MDTM to find the file modification time but I am not able to implement in right way.
Any help on this is much appreciated. Below is the current code:
import ftplib
srcFTP = ftplib.FTP("test.com", "username", "pass")
srcFTP.cwd("/somefolder")
desFTP = ftplib.FTP("test2.com", "username", "pass")
desFTP.cwd("/")
from_Sock = srcFTP.transfercmd("RETR Test1.text")
to_Sock = desFTP.transfercmd("STOR test1.text")
state = 0
while 1:
block = from_Sock.recv(1024)
if len(block) == 0:
break
state += len(block)
while len(block) > 0:
sentlen = to_Sock.send(block)
block = block[sentlen:]
print state, "Total Bytes Transferred"
from_Sock.close()
to_Sock.close()
srcFTP.quit()
desFTP.quit()
Thanks,
DD
Here a short code that takes the path and uploads every file with an extension of .jpg via ftp. Its not exactly what you want but I stumbled on your answer and this might help you on your way.
import os
from ftplib import FTP
def ftpPush(filepathSource, filename, filepathDestination):
ftp = FTP(IP, username, password)
ftp.cwd(filepathDestination)
ftp.storlines("STOR "+filename, open(filepathSource+filename, 'r'))
ftp.quit()
path = '/some/path/'
for fileName in os.listdir(path):
if fileName.endswith(".jpg"):
ftpPush(filepathSource=path, filename=fileName, filepathDestination='/some/destination/')
The creation time of a file can be checked on an ftp server using this example.
fileName = "nameOfFile.txt"
modifiedTime = ftp.sendcmd('MDTM ' + fileName)
# successful response: '213 20120222090254'
ftp.quit()
Now you just need to check when the file that have been modified, download it if it is below you wished for threshold and then upload them to the other computer.
quick and simple:
I have the following function, works well if i specify the file name.
import os
import ftplib
def ftpcon(self, host, port, login, pwd, path):
ftp = ftplib.FTP()
ftp.connect(host, port, 20)
try:
ftp.login(login, pwd)
ftp.cwd(path)
for files in ftp.nlst():
if files.endswith('.doc') or files.endswith('.DOC'):
ftp.retrbinary('RETR ' + files, open(file, 'wb').write)
print files
But when i use the for loop with ftp.nlst() to try to match an specific type of file, i receive the error:
coercing to Unicode: need string or buffer, type found
Since im not sure if this is the best way to do it, what could the "correct" way to download a file ?
Maybe try:
from ftplib import FTP
server = FTP("ip/serveradress")
server.login("user", "password")
server.retrlines("LIST") # Will show a FTP content list.
server.cwd("Name_Of_Folder_in_FTP_to_browse_to") # browse to folder containing your file for DL
then:
server.sendcmd("TYPE i") # ready for file transfer
server.retrbinary("RETR %s"%("FILENAME+EXT to DL"), open("DESTINATIONPATH+EXT", "wb").write) # this will transfer the selected file...to selected path/file
believe this is as correct as serves..
u can set server.set_debuglevel(0) to (1) or (2) for more detailed description while logged in to server.
