Question

我对python很新。我试图通过脚本从某个域获取whois状态。我使用的是Microsoft的whois（https://technet.microsoft.com/en-us/sysinternals/whois）。

我需要运行一个简单的命令来检索状态

whois stackoverflow.com

有了这个，我会得到一个如下所示的输出：

L:\Programming>hello.py

我想要实现的是从该域中检索过期数据，并将其放入文件中。我可以找到＆＃34;注册商注册到期日期：＆＃34;存在，但如何在＆＃34;日期之后检索日期：＆＃34; ？我希望你能帮助我。这就是我得到的安慰

print("Starting...")
import subprocess

findStatus = "Registrar Registration Expiration Date:"

whoOutput = subprocess.Popen(["whois", "stackoverflow.com"],shell=True,stdout=subprocess.PIPE).stdout.read().decode("utf-8")

print(whoOutput)

if findStatus in whoOutput:
    print("\nFound!")
else:
    print("\nNot found")

Answer 1

使用正则表达式：

import re
re.search('Registrar Registration Expiration Date: (.*)', whoOutput)

没有正则表达式：

[i.replace('Registrar Registration Expiration Date: ', '') for i in whoOutput.splitlines() if 'Registrar Registration Expiration Date' in i][0]

或更简单：

[i.split(': ')[1] for i in whoOutput.splitlines() if 'Registrar Registration Expiration Date' in i][0]

Answer 2

您想要的是调用whois，遍历结果，使用正则表达式扫描每一行并在找到匹配项时写入文件。像这样：

error: 'lol'

在字符串中查找子字符串后检索下一个x字符
