如何在python中将字符串转换为ip地址

Question

如何将字符串IP地址转换为十进制数字.例如,我有一个数据字节= b'363,3,1778952384,7076',这里1778952384是我的IP地址,7076是我的端口.如何将我的IP地址转换为十进制数.下面是我的代码,请帮我解决这些问题

/app.py

import socket
from tornado.tcpclient import TCPClient
from tornado import gen

@gen.coroutine
def f(self, message):

    global stream
    client = TCPClient()
    stream = yield client.connect('192.168.8.108', 2620, max_buffer_size=int(1e9))
    msg = '192.168.8.101, 8000'.encode('utf-8')
    yield stream.write(msg)
    data = yield stream.read_bytes(21)
    print("bytes=",data) #bytes= b'363,3,1778952384,7076

Python有一个ipaddress模块,可以处理这种事情.它已添加到Python 3中的标准库中,但也应该可以安装早期版本.

>>> import ipaddress
>>> print(ipaddress.ip_address(1778952384))
IPv4Address('106.8.168.192')
>>> print(str(ipaddress.ip_address(1778952384)))
'106.8.168.192'

您可能还会询问是否要拆分字符串(b','因为它是字节串),获取正确的字段,并将其转换为int:

data = b'363,3,1778952384,7076'
ipaddress.ip_address(int(data.split(b',')[2]))
