How to implement domain name resolution without login in Python
目的是编写python脚本,通过dnspod api获取个人域名内的dns解析记录,
免登录实现域名的解析、修改和删除:
为什么要编写这个脚本?当你在公司负责很多的域名又经常需要解析和查看,频繁登录网站去查去修改是一件费神的事。
上图的账号内有2个域名ssw.fit和ssw.ski,我想給ssw.ski增加了一条A记录,
把test子域名解析到我的linux云服务器,添加完后访问test.ssw.ski
如何获得域名解析信息
使用dnspod api
#获取domain_id curl 'https://dnsapi.cn/Domain.List' -d 'login_token=&format=json' #获取record_id curl 'https://dnsapi.cn/Record.List' -d 'login_token=&format=json&domain_id='
获取Token
访问https://console.dnspod.cn/account/token/token,创建一个秘钥
完成后程序中可以使用ID,TOKEN来访问api。
目标实现
一般都通过requests 的post方法访问对应网址。
不过这里用curl命令更简介方便,它也可以发起post请求,并且一条命令解决。
所以用python来执行linux下的curl命令就可以了:
class DomainHandler(object): def __init__(self): pass def exec_cmd(self,cmd): res = Popen(cmd, shell=True, stdout=PIPE) ret = res.communicate()[0].decode('utf-8') return ret.strip()
下面以添加A记录为例。
添加字典对应函数入口:
dic = { '1':DomainHandler().add, '2':DomainHandler().mod, '3':DomainHandler().delete } tag = True while tag: print(''' 1.增加 2.修改 3.删除 q.退出 ''') choice = input('\033[1;42m输入选项:\033[0m').strip() if not choice: continue if choice == 'q': break if choice in dic: dic[choice]() else: print('\033[31m选项不存在\033[0m')
添加记录的入口函数:
def add(self): self.domain_info() while tag: self.domain_id = input('\033[1;42m输入域名ID:\033[0m').strip() if self.domain_id == 'q': break if not self.domain_id or not self.domain_id.isdigit(): print('\033[31merror id\033[0m') continue self.sub_domain = input('\033[1;42m子域名[@或*等]:\033[0m').strip() self.record_type = input('\033[1;42m类型[A或CNAME]:\033[0m').strip() self.address = input('\033[1;42m记录值(ip或域名):\033[0m').strip() if not self.sub_domain or not self.record_type or not self.address: print('\033[31m参数不能为空\033[0m') continue self.add_Arecord(self.domain_id,self.sub_domain,self.record_type,self.address) if self.domain_id == 'q' or self.record_type == 'q' or self.address == 'q': self.tag = False break
获取域名信息:
def domain_info(self): cmd = 'curl -s https://dnsapi.cn/Domain.List -d "login_token=391845,92f408bb5343e&format=json"' data = json.loads(self.exec_cmd(cmd)) print(data) for item in data['domains']: print('%s:%s' % (item['name'], item['id']))
添加记录:
def add_Arecord(self,domain_id,sub_domain,record_type,address): print(domain_id,sub_domain,record_type,address) cmd2 = "curl -s -X POST https://dnsapi.cn/Record.Create -d 'login_token=391845,92f408bb5343e&format=json&domain_id={0}&sub_domain={1}&record_type={2}&record_line_id=0&value={3}'".format( domain_id, sub_domain, record_type, address) r = json.loads(self.exec_cmd(cmd2)) print(r['status']['message'])
修改记录
我想把test.ssw.ski的ip修改为1.1.1.1
ipconfig/flushdns刷新一下dns缓存,生效了:
文章还没写完,它就检测到域名未备案了

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

To run Python code in Sublime Text, you need to install the Python plug-in first, then create a .py file and write the code, and finally press Ctrl B to run the code, and the output will be displayed in the console.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development.
