利用EXCLE生成CSV文档，批量处理nslookup解析。并保存为CSV文档，方便进行查看：
输入文档格式：
data\\domain.csv
最终输出文档情况：
data\\nlookup.csv
代码：
# coding=gbk
import subprocess
import csv
def get_nslookup(domain, dns):
res = subprocess.Popen(\"nslookup {0} {1}\".format(domain, dns), stdin=subprocess.PIPE,
stdout=subprocess.PIPE).communicate()[0]
response = res.decode(\"gbk\")
res_list = response.split(\"s:\")
row_nslookup = [domain, dns]
row_ip = res_list[2].split()[:-1]
row_nslookup.extend(row_ip)
return row_nslookup
if __name__ == \"__main__\":
file_domain = r\'data\\domain.csv\' # 输入文件
file_nslookup = r\'data\\nslookup.csv\' # 输出文件
with open(file_domain, \'r\', newline=\'\', encoding=\'gbk\') as rf:
domain_csv = csv.DictReader(rf, dialect=csv.excel)
domain_list = [row[\'domain\'] for row in domain_csv]
with open(file_domain, \'r\', newline=\'\', encoding=\'gbk\') as rf:
domain_csv = csv.DictReader(rf, dialect=csv.excel)
dns_list = []
for row in domain_csv:
print(row[\'DNS\'])
if row[\'DNS\'] != \'\': # 通常DNS数量少于需要监测的域名数量，做去空处理
dns_list.append(row[\'DNS\'])
with open(file_nslookup, \'w+\', newline=\'\', encoding=\'gbk\') as wf:
nslookup_csv = csv.writer(wf, dialect=csv.excel)
header = [\'domain\', \'DNS\', \'nslookup_res...\']
nslookup_csv.writerow(header)
for domain in domain_list:
for dns in dns_list:
print(\'解析中：域名：{0}___DNS：{1}\'.format(domain, dns))
row_nslookup = get_nslookup(domain, dns)
nslookup_csv.writerow(row_nslookup)
print(\'执行完毕\')
