dnspython模块报错 AttributeError: 'CNAME' object has no attribute 'address'

有时候用到这个模块的时候会报错

AttributeError: 'CNAME' object has no attribute 'address'

如下所示

[root@ansible ch01]# ./dnspython_ex1.py

Please input a domain: www.baidu.com

Traceback (most recent call last):

  File "./dnspython_ex1.py", line 9, in <module>

    print(j.address)

AttributeError: 'CNAME' object has no attribute 'address'

代码是这样的：

#!/usr/bin/env python

import dns.resolver

domain = raw_input('Please input a domain: ')

A = dns.resolver.query(domain, 'A')

for i in A.response.answer:

    for j in i.items:

        print j.address

我们只需在最后需要输出address时在前面增加if判断

if j.rdtype == 1:

将代码修改如下：

#!/usr/bin/env python

import dns.resolver

domain = raw_input('Please input a domain: ')

A = dns.resolver.query(domain, 'A')

for i in A.response.answer:

    for j in i.items:

        if j.rdtype == 1:

            print j.address

运行就不会报错了

[root@ansible ch01]# ./dnspython_ex1.py

Please input a domain: www.baidu.com
