DNSPod动态IP解析更新程序

说明

如果通过外网访问内网服务，但是家居的网络IP经常变化，需要绑定一个域名和动态IP

步骤

编写Python程序

#!/usr/bin/env python
#-*- coding:utf-8 -*-
 
import httplib, urllib
import socket
import time
 
params = dict(
    login_email="email", # replace with your email
    login_password="password", # replace with your password
    format="json",
    domain_id=100, # replace with your domain_od, can get it by API Domain.List
    record_id=100, # replace with your record_id, can get it by API Record.List
    sub_domain="www", # replace with your sub_domain
    record_line="默认",
)
current_ip = None
 
def ddns(ip):
    params.update(dict(value=ip))
    headers = {"Content-type": "application/x-www-form-urlencoded", "Accept": "text/json"}
    conn = httplib.HTTPSConnection("dnsapi.cn")
    conn.request("POST", "/Record.Ddns", urllib.urlencode(params), headers)
     
    response = conn.getresponse()
    print response.status, response.reason
    data = response.read()
    print data
    conn.close()
    return response.status == 200
 
def getip():
    sock = socket.create_connection(('ns1.dnspod.net', 6666))
    ip = sock.recv(16)
    sock.close()
    return ip
 
if __name__ == '__main__':
    while True:
        try:
            ip = getip()
            print ip
            if current_ip != ip:
                if ddns(ip):
                    current_ip = ip
        except Exception, e:
            print e
            pass
        time.sleep(30)

如何使用，替换上你的Email，密码，域名ID，记录ID等参数，就可以运行了。会在后台一直运行，每隔30秒检查一遍IP，如果修改了就更新IP。
获得domain_id方法

curl curl -k https://dnsapi.cn/Domain.List -d "login_email=xxx&login_password=xxx"

获得record_id方法

curl -k https://dnsapi.cn/Record.List -d "login_email=xxx&login_password=xxx&domain_id=xxx"

开机自动运行的方法，编辑/etc/rc.local文件，在“exit 0”那一行前面加上一行

su root -c "python /home/pypod.py"
