Python ftplib在将文件上传到FTP服务器的过程中向txt文件添加新行

Question

I use following code to upload txt files in ASCII mode to FTP server

import glob
import os
import hashlib
from ftplib import FTP 

server = '1.1.1.1'
login = 'user'
password = 'password'
path = './test_files/'
file_mask = '*.txt'

def upload_to_ftp(srv, uname, pwd, file_name):
    ftp = FTP(srv, uname, pwd)    
    ftp.cwd('Pava')    
    file = open(path+file_name, 'rb')
    ftp.storlines('STOR '+file_name, file)
    size = ftp.size(file_name)           
    ftp.close()
    file.close()
    print (size)

def local_size_check(file_name):
    file_size = os.stat(path+file_name)
    print (file_size.st_size)


file_to_upload = glob.glob1(path, file_mask)
for i in file_to_upload:
    try:
        os.rename(path+i, path+i)
    except OSError as e:
        print ('Access-error on file ' + i + ' ! \n' + str(e))
    else:
        upload_to_ftp(server, login, password, i)
        local_size_check(i)

The output of this two functions is: 78 76 Then i have dowloaded file from ftp and found that during transfering by FTP was added new line at the end of file. local and remote file screens

Please help to solve this problem. BTW if use binary mode new line do not add

Answer 1

You should upload your file in binary mode so that it will not be subject to the server's text interpretation.

Change:

ftp.storlines('STOR '+file_name, file)

to:

ftp.storbinary('STOR '+file_name, file)
