Python腳本實現(xiàn)DNSPod DNS動態(tài)解析域名

這篇文章主要介紹了Python腳本實現(xiàn)DNSPod DNS動態(tài)解析域名,本文直接給出實現(xiàn)代碼,需要的朋友可以參考下

閑暇之余，在家里自建了個服務(wù)器，因為用的小區(qū)寬帶，IP位動態(tài)分配。域名解析就是個問題，我的域名一般停放在DNSPod下。DNSPod有提供修改的API，就用Python簡單的實現(xiàn)了一下動態(tài)解析。這樣，就不用安裝花生殼了。廢話不說，看代碼：

#!/usr/bin/env python
#-*- coding:utf-8 -*-

import httplib, urllib, urllib2
import time
import sys,os
import re
import json

username = 'xxxx' #賬號
password = 'xxx' #密碼
format = 'json'

domain = [u'www.youdomain.com'] #要解析的域名

def get_domain_info(domain):
  domain_split = domain.split('.')
  domain_split_len = len(domain_split)
  maindomain = domain_split[domain_split_len - 2] + '.' + domain_split[domain_split_len - 1]
  return maindomain,domain

params = {'login_email':username,'login_password':password,'format':format}

def request(action, params, method = 'POST'):
  headers = {"Content-type": "application/x-www-form-urlencoded", "Accept": "text/json"}
  conn = httplib.HTTPSConnection("dnsapi.cn")
  conn.request(method, '/' + action, urllib.urlencode(params), headers)
  response = conn.getresponse()
  data = response.read()
  conn.close()
  if response.status == 200:
    return data
  else:
    return None

def get_my_domain_id():
  data = request('Domain.List',params)
  data = json.loads(data)
  domainlist = data.get('domains')
  domaninfo = {}
  for d in domainlist:
    domaninfo[d.get('name')] = d.get('id')
  return domaninfo

def get_my_domain_record_id(domain_id):
  params['domain_id'] = domain_id
  data = request('Record.List',params)
  data = json.loads(data)
  if data.get('code') == '10':
    return None
  domainname = data.get('domain').get('name')
  record_list = data.get('records')
  record = {}
  for r in record_list:
    if r.get('type') == 'A':
      key = r.get('name') != '@' and r.get('name') + '.' + domainname or domainname
      record[key] = {'id':r.get('id'),'value':r.get('value')}
  return record

def changerecord(domain,domain_id,record_id,ip):
  params['domain_id'] = domain_id
  params['record_id'] = record_id
  params['record_type'] = 'A'
  params['record_line'] = '默認(rèn)'
  params['sub_domain'] = domain
  params['ttl'] = 600
  params['value'] = ip
  data = request('Record.Modify',params)

def getip():
  url = 'http://iframe.ip138.com/ic.asp'
  response = urllib2.urlopen(url)
  text = response.read()
  ip = re.findall(r'\d+.\d+.\d+.\d+', text)
  return ip[0] or None

def updatedomaininfo(domain):
  m,sub_m = get_domain_info(domain)
  domain_id = my_domain_id_list.get(m)
  record_list = get_my_domain_record_id(domain_id)
  if record_list == None:
    return None
  rocord_info = record_list.get(sub_m)
  record_ip = rocord_info.get('value')
  record_id = rocord_info.get('id')
  return sub_m,record_ip,record_id,domain_id

if __name__ == '__main__':
  my_domain_id_list = get_my_domain_id()
  try:
    for dm in domain:
      domaindata = updatedomaininfo(dm)
      if domaindata == None:
        continue
      dnsdomain,dnsdmainip,record_id,domain_id = domaindata
      domain_name = dnsdomain.split('.')[0]
      ip = getip()
      if ip == dnsdmainip:
        continue
      else:
        changerecord(domain_name,domain_id,record_id,ip)
  except:
    pass
