Uploading PDF through FTP using Python

Bubacz_Hannah — Thu, 04 Mar 2021 16:53:24 GMT

Hello, I am trying to upload a PDF using Python to an outside FTP server. However, I keep getting the error about concatenating string and and file objects.

CODE:

import ftplib

# Logging into ftp site with login information
session = ftplib.FTP("host","username","password")
print('Logging in')

# Choosing file to send
filename = "TEST12142020.pdf"
filepath = open(r'G:\\GIS\\filepath\\TEST12142020.pdf', 'rb')
print ('Opened file')

# Sending the file
print('Sending file')
session.storbinary('STOR ' + filepath, filename)
print('Sent file')

# Closing file and ftp
file.close()
print('Closing file')
session.quit()

ERROR:

Logging in
Opened file
Sending file
Traceback (most recent call last):
File "G:\pathname\UploadtoFTPTest.py", line 14, in <module>
session.storbinary('STOR ' + filepath, filename)
TypeError: cannot concatenate 'str' and 'file' objects

filepath = open(r'G:\\GIS\\filepath\\TEST12142020.pdf', 'rb')

You made this a file object.

Did you mean

filepath = r'G:\\GIS\\filepath'

and the previous to be something like

file_object = open(r'G:\\GIS\\filepath\\TEST12142020.pdf', 'rb')

Then decide what actually needs to go in here

session.storbinary('STOR ' + ???, ????)

Hey Dan, so like this? I get the same error.

filepath = r'G:\\GIS\\filepath'
file_object = open(r'G:\\GIS\\filepath\\TEST12142020.pdf', 'rb')
print ('Opened file')

# Sending the file
print('Sending file')
session.storbinary('STOR ' + file_object, filepath)
print('Sent file')

I also get the same error doing this:

# Choosing file to send
filename = open(r'G:\\GIS\\filepath\\TEST12142020.pdf', 'rb')
print ('Opened file')

# Sending the file
print('Sending file')
session.storbinary('STOR ' + filename)
print('Sent file')

As the error says, you cannot concatenate 'str' and 'file' objects. You'd have to do something like

filepath = r'G:\\GIS\\filepath' file_object = open(r'G:\\GIS\\filepath\\TEST12142020.pdf', 'rb') print ('Opened file') # Sending the file print('Sending file') session.storbinary('STOR ' + filepath, file_object) print('Sent file')

Ah, I didn't realize that filepath and file_object were actualy variable names that it would recognize, not just what I chose to call it. I am running the code through Notepad++ with Run on Python27 and got these errors:

Re: Uploading PDF through FTP using Python

You formatted the file path a a raw string but then included the escape backslash. You have to do one or the other. I recommend just using the raw string with single backslashes.

filepath = r'G:\GIS\filepath' file_object = open(r'G:\GIS\\filepath\TEST12142020.pdf', 'rb') print ('Opened file') # Sending the file print('Sending file') session.storbinary('STOR ' + filepath, file_object) print('Sent file')

Re: Uploading PDF through FTP using Python

Bubacz_Hannah — Thu, 04 Mar 2021 19:00:15 GMT

Ah, my bad. You are right. I changed it to this:

filepath = r'G:\GIS\Departments\ItmdGis\Users\hbubac\Data and Scripts\Crime Maps\new scripts'
file_object = open(r'G:\GIS\Departments\ItmdGis\Users\hbubac\Data and Scripts\Crime Maps\new scripts\TEST12142020.pdf', 'rb')
print ('Opened file')

# Sending the file
print('Sending file')
session.storbinary('STOR ' + filepath, file_object)
print('Sent file')

And still got this for an error:

Logging in
Opened file
Sending file
Traceback (most recent call last):
File "G:\GIS\Departments\ItmdGis\Users\hbubac\Data and Scripts\Crime Maps\new scripts\UploadtoFTPTest.py", line 14, in <module>

Re: Uploading PDF through FTP using Python

BlakeTerhune — Thu, 04 Mar 2021 19:06:34 GMT

The command input needs to be a path to the file, not a folder. Try

filepath = r'G:\GIS\filepath\TEST12142020.pdf' file_object = open(filepath, 'rb') print ('Opened file') # Sending the file print('Sending file') session.storbinary('STOR ' + filepath, file_object) print('Sent file')

Re: Uploading PDF through FTP using Python

Bubacz_Hannah — Thu, 04 Mar 2021 19:10:35 GMT

Hmmm, looks like the same error. Maybe I need to run it some way different than Python 27? Or my Python version is getting mixed up because I have both ArcMap and ArcPro installed on my computer?

CODE:

# Choosing file to send
filepath = r'G:\GIS\filepath\TEST12142020.pdf'
file_object = open(filepath, 'rb')
print ('Opened file')

# Sending the file
print('Sending file')
session.storbinary('STOR ' + filepath, file_object)
print('Sent file')

Re: Uploading PDF through FTP using Python

Try putting the file in a simpler directory, like C:\temp\TEST12142020.pdf

According to this, try just using the file name in the command.

# Choosing file to send filename = 'TEST12142020.pdf' filepath = r'C:\temp\{}'.format(filename) file_object = open(filepath, 'rb') print ('Opened file') # Sending the file print('Sending file') session.storbinary('STOR ' + filename, file_object) print('Sent file')

Re: Uploading PDF through FTP using Python

JoshuaBixby — Thu, 04 Mar 2021 19:56:35 GMT

The "filename" is the name you want on the FTP Server, not the name of the file on the local machine. The local file is already addressed through the file object being passed to the command.

That worked! Perfect, thank you. I still have some finagling but this is definitely one step closer. If you don't mind, one more question. It uploaded the file but then I got an error about my closing of the file. I tried closing filepath, file_object, and filename and all got the error saying it received a string.

# Choosing file to send
filename = 'TEST12142020.pdf'
filepath = r'C:\temp\{}'.format(filename)
file_object = open(filepath, 'rb')
print ('Opened file')

# Sending the file
print('Sending file')
session.storbinary('STOR ' + filename, file_object)
print('Sent file')

# Closing file and ftp
file.close(filepath)
print('Closing file')
session.quit()

ERROR:

Logging in
Opened file
Sending file
Sent file
Traceback (most recent call last):
File "C:\temp\UploadtoFTPTest.py", line 19, in <module>
file.close(filepath)

Re: Uploading PDF through FTP using Python

BlakeTerhune — Thu, 04 Mar 2021 21:00:32 GMT

Don't pass anything as an argument. Just do file_object.close()

However, a better way would be to use the with keyword to open and automatically close the file. Otherwise, you should be using a try/except/finally with open/close.

# define ftp session out here try: # Choosing file to send filename = 'TEST12142020.pdf' filepath = r'C:\temp\{}'.format(filename) with open(filepath, 'rb') as file: print ('Opened file') # Sending the file print('Sending file') session.storbinary('STOR ' + filename, file) print('Sent file') finally: session.quit()

Hello,

Could you help me with one more thing? I need to put it in a certain folder within the ftp site but cannot figure out the code. Thoughts? Thanks!

The folder I need it in:

CODE:

# Sending the file
print('Sending file')
session.storbinary('STOR {/srv/ftp/pub/gis/crimemaps}' + filename, file_object)
print('Sent file')

ERROR:

<module>

File "C:\Python27\ArcGIS10.5\lib\ftplib.py", line 471, in storbinary
conn = self.transfercmd(cmd, rest)
File "C:\Python27\ArcGIS10.5\lib\ftplib.py", line 376, in transfercmd
return self.ntransfercmd(cmd, rest)[0]

Change the working directory before you call the STOR command to copy the file.

session.cwd('/srv/ftp/pub/crimemaps') # Sending the file print('Sending file') session.storbinary('STOR ' + filename, file_object) print('Sent file')
