[debug]取本地ipv6地址时出错

[ghost]

描述问题 (Describe the bug)

取本地ipv6地址时出错，想要直接取本地网卡(ens33)的ipv6地址(光猫直接分配的)，在getaddrinfo时出错。

版本信息 (version info)

• DDNS Version: v2.12.0@2022-12-07
• OS Version： ubuntu18.04
• Type(运行方式): Python3
• related issues (相关问题):

复现步骤 (To Reproduce)

配置config.json，执行ddns -c config.json
ip addr 执行显示ens33是第二个网卡

配置文件 (config file)

config.json
{
"token": "xxxxxxxxxxxxxx",
"dns": "cloudflare",
"ipv4": [],
"ipv6": ["xxx.yyyyy.com"],
"index6": 1,
"debug": true
}

调试输出 (debug output)

Traceback (most recent call last):
File "/usr/local/bin/ddns", line 8, in
sys.exit(main())
File "/usr/local/lib/python3.8/dist-packages/run.py", line 151, in main
update_ip('6', cache, dns, proxy_list)
File "/usr/local/lib/python3.8/dist-packages/run.py", line 97, in update_ip
address = get_ip(ip_type, index_rule)
File "/usr/local/lib/python3.8/dist-packages/run.py", line 51, in get_ip
value = getattr(ip, "local_v" + ip_type)(index)
File "/usr/local/lib/python3.8/dist-packages/util/ip.py", line 38, in local_v6
info = getaddrinfo(gethostname(), 0, AF_INET6)
File "/usr/lib/python3.8/socket.py", line 918, in getaddrinfo
for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno -5] No address associated with hostname

补充说明 (Additional context)

/etc/hosts中配置为127.0.1.1 ubuntu
手动执行getaddrinfo(gethostname(), 0, AF_INET)时返回的是127.0.0.1，好像ipv4也没有达到获取某网卡地址的功能，这个功能原想法应该不是想要获取lo回环地址吧？

现在暂时用default方式实现的。

我是使用shell的形式进行获取ipv6地址
"index6": "shell: /usr/sbin/ifconfig eth0 | egrep -o '24.*:.*:[a-z0-9]{3,4}:[a-z0-9]{3,4}' | head -n 1",
这段代码在树莓派4B (基于debian 12)上是可以运行的.
