到期域名查询（Python批量查询域名whois信息）

前言由于公司有大量域名信息需要定期查看是否需要续期，前期都是人工操作比较耗时、耗力。所以衍生了这个小工具。实现了查询域名到期时间、并且将近7天内到期的域名在Excel中标红，当然你也可以添加短信提醒和邮件提醒代码步骤1、将域名粘贴到指定txt文件中比如：domain.txt2、将指定txt文件中内容读取到list中# 批量读取文件中的域名
def read_file(filePath):
with open(filePath, "r") as f: # 打开文件
data = f.readlines() # 读取文件
return data3、通过某网站获取域名到期时间# 通过某网站获取域名到期时间
def get_expiry_date(url_list):
url_expiry_date_list = []
for url in url_list:
url_expiry_date_dict = {}
time.sleep(random.randrange(3))
req_whois = urllib.request.urlopen('http://whois.xxxxxx.com/' + url)
result = req_whois.read().decode()
html = etree.HTML(result)

endTimes = html.xpath('//a[@id="update_a2"]/preceding-sibling::span[1]/text()')
if len(endTimes) > 0:
endTime = endTimes[0].replace('年', '-').replace('月', '-').replace('日', '')
else:
errorInfo = html.xpath('//div[@class="IcpMain02"]')
endTime = errorInfo[0].xpath('string(.)').strip()
url_expiry_date_dict['url'] = url.replace('\n', '')
url_expiry_date_dict['endTime'] = endTime
pprint.pprint(url_expiry_date_dict)
url_expiry_date_list.append(url_expiry_date_dict)
pprint.pprint(url_expiry_date_list)
return url_expiry_date_list4、将结果写入Excel文件# 写入Excel文件
def write_excel(domain_list):
# 创建一个新的文件
with xlsxwriter.Workbook('host_ip.xlsx') as workbook:
# 添加一个工作表
worksheet = workbook.add_worksheet('域名信息')
# 设置一个加粗的格式
bold = workbook.add_format({"bold": True})
# 分别设置一下 A 和 B 列的宽度
worksheet.set_column('A:A', 50)
worksheet.set_column('B:B', 15)
# 先把表格的抬头写上，并设置字体加粗
worksheet.write('A1', '域名', bold)
worksheet.write('B1', '信息', bold)
# 设置数据写入文件的初始行和列的索引位置
row = 1
col = 0
for domain_ex_date in domain_list:
url = domain_ex_date['url']
endTime = domain_ex_date['endTime']
currDate = datetime.today().date()
try:
endDate = datetime.strptime(endTime, "%Y-%m-%d").date()
diffDate = endDate – currDate
if diffDate.days <= 7:
style = workbook.add_format({'font_color': "red"})
else:
style = workbook.add_format({'font_color': "black"})
except:
style = workbook.add_format({'font_color': "red"})
pprint.pprint(url + ': ' + endTime)
worksheet.write(row, col, url, style)
worksheet.write(row, col + 1, endTime, style)
row += 15、运行urls = read_file('domain.txt')
urls_list = get_expiry_date(urls)
write_excel(urls_list)运行结果：6、完整代码#!/usr/bin/env python
