 1 | 该项目为使用aliyun动态解析域名脚本，采用python编写，主要适用于在家里自己捣腾服务器的朋友们。由于家用宽带没有固定ip，所以一旦家里的路由器重新拨号了会分配到新的公网ip地址，这会导致在外网无法访问到服务器。东西很简单，一般有点编程知识的人都能看懂，不过在使用前最好再了解下以下几个注意点：
 2 | 
 3 | 1.请记得保管好你的Access Key，所以我没有在我的代码里直接写Access Key Id和Access Key Secret，我把他们单独放在一个key.json文件中，同时将这个文件排除出git，保证只有我自己知道，因为一旦这两个值泄露了那别人就可以直接修改你的域名了。
 4 | 
 5 | 2.阿里云通过RecordId来区分每条域名解析记录，但是他们之前文档上对于这个参数的描述只写了“解析记录的ID”，没有写如何获取这条解析记录ID，我去我的阿里云控制台上找了好久都没找到，到后来我突然想到sdk上有获取域名信息的api，我试着用这个果然返回的信息里有这个字段，后来联系了他们客服，他们也说在控制台上没办法找到，也只有通过api获取域名信息才能找到，后来他们也在文档中注明了这个字段的获取方式。
 6 | 
 7 | 3.更新域名解析主要用到的是阿里云sdk包里aliyun/api/rest/Dns20150109UpdateDomainRecordRequest.py 方法，我为了偷懒直接在这个方法里写死了一些需要固定传入的参数，如果你要对自己的域名做解析的话记得去修改这些参数值。

 9 | ## 20230304 update：
10 | 1.更新为使用阿里云python3接口，弃用原先下载sdk包调用形式
11 | 
12 | 2.新增日志输出
