从 txt 文件中读取 IP 并连接到 python 中的 ftp

Reading IPs from txt file and connect to ftp in python

我正在尝试在 python 中编写一个脚本,它连接到我们所有的 ftps 并告诉我它们已启动并在连接时列出它们的目录。

我将尝试使用一个名为 "ips.txt" 的文件,我们所有的 ip 都在其中 - 每行一个和以下脚本:

import socket
import ftplib

username = "xxx"
password = "xxx"



for server in open("ips.txt", "r").readlines():
    try:
        ftp = ftplib.FTP(server)
        welcome = ftp.getwelcome()
        print (welcome)

        try:
            attempt = ftp.login(user=username, passwd=password)
            success = ("[****] Working " + server + '\n')

            print(success)
            data = []
            ftp.dir(data.append)
            for lines in data:
                print (lines)

        except:
            print (server, username, password)
            pass

    except:
        print ("Timeout...")

但脚本似乎跳过了所有内容,只打印了 "Timeout..." :(

我是个python新手,请耐心等待

编辑: 删除外部 try/except 后,我得到了回溯:

    Traceback (most recent call last):
  File "ftp.py", line 12, in <module>
    ftp = ftplib.FTP(server)
  File "C:\Python3.5.1\lib\ftplib.py", line 118, in __init__
    self.connect(host)
  File "C:\Python3.5.1\lib\ftplib.py", line 153, in connect
    source_address=self.source_address)
  File "C:\Python3.5.1\lib\socket.py", line 693, in create_connection
    for res in getaddrinfo(host, port, 0, SOCK_STREAM):
  File "C:\Python3.5.1\lib\socket.py", line 732, in getaddrinfo
    for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno 11001] getaddrinfo failed

ips.txt 看起来像:

10.10.10.10
10.10.10.11
10.10.10.21
10.10.10.33

因此每个 IP 换行

根据您提供的文件,当您进行 readlines 调用时,您仍然保留每个 IP 末尾的换行符。这很可能就是您得到 gaierror 的原因。

在我这边复制,使用换行符,我的回溯产生:

>>> FTP('10.10.10.10\n')

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/ftplib.py", line 118, in __init__
    self.connect(host)
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/ftplib.py", line 153, in connect
    source_address=self.source_address)
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/socket.py", line 693, in create_connection
    for res in getaddrinfo(host, port, 0, SOCK_STREAM):
  File "/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/socket.py", line 732, in getaddrinfo
    for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno 8] nodename nor servname provided, or not known

只需执行:

FTP(server.strip())

然后您将去掉 IP 末尾的 \n,您至少应该调用 正确的 IP 地址。

或者,您 可以 尝试查看 splitlines 是否适合您,考虑到您正在处理单个 IP 地址列表,它可能是一个不错的选择.

splitlines 将为您删除针对 string 的换行符,因此您还需要在打开的对象上调用 read。像这样:

for server in open("ips.txt", "r").read().splitlines():
