Question

我正在使用dnspython获取“A”记录并返回结果（给定域的IP地址）。

我有这个简单的测试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，输出是：

<dns.resolver.Answer object at 0x0000000004F56C50>

我需要将结果作为字符串。如果它是一个字符串数组，如何返回？

Answer 1

你得到的答案实际上是一个＆＃39; A＆＃39;记录，因此您需要遍历这些记录：

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

Answer 2

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

所以现在resultant_str是一个字符串类型的变量，它包含以逗号分隔的A条记录。

在dnspython中返回“A”DNS记录
