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

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')

The error is pretty clear: Can't change directory to /srv/ftp/pub/crimemaps: No such file or directory

Can you verify that path is correct and the folders exist in the ftp site?

 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 ' + ???, ????)

 


... sort of retired...

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:

Logging in

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')

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>

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')

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')
