[size=150]群晖中安装python3、pip3和阿里云Python SDK

安装步骤：
1、从群晖“套件中心”中安装python3应用；
2、通过SSH登录群晖后台，并通过“[color=#4000FF]sudo -i[/color]”命令进入root用户角色；
3、进入python3应用目录”[color=#4000FF]root@DiskStation:/var/packages/py3k/target/usr/local/bin#[/color]“
4、运行下列命令安装pip3
[/size]
[code]wget https://bootstrap.pypa.io/get-pip.py
python3 get-pip.py # 安装pip3
pip3 -V # 查看pip3版本
pip3 install aliyun-python-sdk-core # 安装阿里云SDK核心库
pip3 install aliyun-python-sdk-alidns #安装阿里云DNS库[/code]

pip install aliyun-python-sdk-core # 安装阿里云SDK核心库
pip install aliyun-python-sdk-ecs # 安装管理ECS的库
pip install aliyun-python-sdk-alidns

还需要安装支持库：
[code]
pip install aliyun-python-sdk-core # 安装阿里云SDK核心库
pip install aliyun-python-sdk-ecs # 安装管理ECS的库
pip install aliyun-python-sdk-alidns
[/code]

今天又抽了点时间将IP更新程序优化了一下，调用方法： [color=#FF0000]python aliyundns.py www.atoo.top[/color]，代码如下：
[Codebox=python file=Untitled.py]
# 阿里支DNS自动更新IP地址程序（Python3）
# 文件名 ： aliyundns.py
# 调用方法： python3 aliyundns.py www.atoo.top

#!/usr/bin/env python3
#coding=utf-8

import sys
import json
import urllib.request
import datetime
from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdkalidns.request.v20150109.UpdateDomainRecordRequest import UpdateDomainRecordRequest
from aliyunsdkalidns.request.v20150109.DescribeSubDomainRecordsRequest import DescribeSubDomainRecordsRequest

if len(sys.argv)<=1:
print( 'Usage: python3 aliyundna.py www.atoo.top')
sys.exit(0)

accessKeyId = 'LTAIjO23**PWBfI'
accessSecret = 'JlvkmaC***514aFM9Z14JGQbd8Zp'

DomainName = sys.argv[1]

# print sys.argv[0], sys.argv[1], sys.argv[2]

client = AcsClient(accessKeyId, accessSecret, 'cn-hangzhou')

request = DescribeSubDomainRecordsRequest()
request.set_accept_format('json')
request.set_SubDomain(DomainName)
response = client.do_action_with_exception(request)
# print response
response = json.loads(response.decode())
RecordId = response['DomainRecords']['Record'][0]['RecordId']
RR = response['DomainRecords']['Record'][0]['RR']
old_ip = response['DomainRecords']['Record'][0]['Value']

new_ip = urllib.request.urlopen("http://ip.42.pl/raw").read()


if old_ip != str(new_ip, 'utf-8'):
request = UpdateDomainRecordRequest()
request.set_accept_format('json')

request.set_Value(new_ip)
request.set_Type("A")
request.set_RR(RR)
request.set_RecordId(RecordId)

response = client.do_action_with_exception(request)
print( datetime.datetime.now(), ' ', DomainName,': ', old_ip, ' => ', new_ip )
# else :
# print datetime.datetime.now(), ' ', DomainName, ': IP has not changed.', new_ip

在群晖的计划任务中，定时执行下面的命令，就可定时查询更新aliyun的DNS解析：
[Codebox=bash file=Untitled.bsh]#!/bin/ash
sudo python /volume1/run/aliyundns.py >> /volume1/run/ddns.log[/Codebox]

花9元钱在阿里云上云注册一个“.top”的顶级域名，再利用下面的代码定时更新你家路由器的IP，这样就实现了DDNS的效果了。
下面Python代码中的AcsClient（）、request.set_RecordId("17741030***760")这两个函数的参数请在https://help.aliyun.com/document_detail/53090.html 上查看。
