在dnspython中返回'A‘DNS记录

Question

我使用强的松获取'A‘记录并返回结果(给定域的IP地址)。

我有一个简单的测试python脚本：

import dns.resolver

def resolveDNS():
    domain = "google.com" 
    resolver = dns.resolver.Resolver(); 
    answer = resolver.query(domain , "A")
    return answer

resultDNS = resolveDNS()
print resultDNS

然而，产出是：

<dns.resolver.Answer object at 0x0000000004F56C50>

我需要得到一个字符串的结果。如果它是一个字符串数组，如何返回它？

Answer 1

import dns.resolver

def resolveDNS():
    domain = "google.com" 
    resolver = dns.resolver.Resolver(); 
    answer = resolver.query(domain , "A")
    return answer

resultDNS = resolveDNS()
answer = ''

for item in resultDNS:
    resultant_str = ','.join([str(item), answer])

print resultant_str

现在，resultant_str是一个字符串类型的变量，它保存用逗号分隔的A记录。

Answer 2

您得到的答案实际上是“A”记录的迭代器，因此您需要迭代这些记录：

answers = resolver.query(domain, 'A')
for answer in answers:
    print (answer.to_text())
