python写网站（Python快速实现一个域名）

域名和ip地址信息是非常基础的情报信息，目前网上有很多网站都提供了域名信息的查询、IP地址及归属地的查询。本文通过Python Flask实现域名及IP情报信息的聚合网站。因为域名和IP地址信息会有变化，为了减少接口压力，做了本地数据库的存储，新鲜度保存一周，每次查询先从本地数据库获取信息，如果本地库信息有并且没有超过一个星期就从本地库取，没有就从其他网站获取，并更新到本地库。一、获取域名WHOIS信息网上提供域名WHOIS信息查询的网站有很多，这里以http://whois.chinafu.com 为例实现WHOIS信息的查询和解析。1

import requests
from bs4 import BeautifulSoup
headers = {
'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.116 Safari/537.36'
}

def getwhoisinfobychinafu(domain):
ret_result = {}
result=getWhoisInfoFromDB(domain)
if len(result)==0:
whois_service_url = 'http://whois.chinafu.com/whois.php'
post_data={"domain":domain}

try:
post_result=requests.post(whois_service_url,post_data)
if post_result.status_code == 200:
ret_str = post_result.content.decode('utf-8')
soup = BeautifulSoup(ret_str, 'lxml')
items_tr =soup.find(name='table',attrs={'class':'listtable'}).find_all(name='tr')
for item_tr in items_tr:
td_item=item_tr.find(name='td')
if 'colspan' in td_item.attrs:
key_name='详情'
key_value=td_item.find(name='div',id='tab1').text
else:
key_name=item_tr.find(name='th').text
key_value=item_tr.find(name='td').text
ret_result[key_name]=key_value
addchinafuWhoisInfo2DB(ret_result)
except Exception as r:
print('未知错误 %s' % (r))
#ret_result = json.dumps(ret_result, ensure_ascii=False)
else:
ret_result=result[0]
return ret_result

def getWhoisInfoFromDB(domainname):
whoisInfos=db.session.execute('select * from whoisinfo where domain_name="%s" and updated_time > DATE_SUB(CURDATE(), INTERVAL 1 WEEK)' % domainname).fetchall()
whoisInfo_dics=[]
for whoisInfo in whoisInfos:
chinafuwhoisinfo_dic=chinafuwhoisinfo2dic(whoisInfo)
whoisInfo_dics.append(chinafuwhoisinfo_dic)
return whoisInfo_dics

def addchinafuWhoisInfo2DB(chinafuWhoisInfo_dic):
chinafuWhois=WhoisInfo()
chinafuWhois.domain_name=chinafuWhoisInfo_dic.get('域名DomainName')
chinafuWhois.domain_status=chinafuWhoisInfo_dic.get('域名状态Domain Status','')

chinafuWhois.detail=chinafuWhoisInfo_dic.get('详情', '')[0:10000]
chinafuWhois.source = '中国福网'
db.session.execute('delete from whoisinfo where domain_name="%s" and source="%s"' % (chinafuWhoisInfo_dic.get('域名DomainName'), chinafuWhois.source))
db.session.add(chinafuWhois)
db.session.commit()
这里为了减少直接从其他网站获取WHOIS信息的压力，做了本地数据库的存储，每次先从本地数据库取WHOIS的信息，如果本地库信息有并且没有超过一个星期就从本地库取，没有就从其他网站获取，并更新到本地库。这里getWhoisInfoFromDB实现了取新鲜度为1周的数据，addchinafuWhoisInfo2DB实现将获取的信息保存到本地数据库。二、根据域名解析出IP根据域名解析出IP代码：1

def getIPbyDomain(domain):
addr=''
try:
myaddr = socket.getaddrinfo(domain, 'http')
addr=myaddr[0][4][0]
except Exception as e:
print(e)
return addr
三、获取IP信息获取IP信息的API接口也有很多，有淘宝的 https://ip.taobao.com/outGetIpInfo 、IPINFO http://ipinfo.io/、IPAPI http://ip-api.com/ 以及GeoLite2离线库等。从淘宝IP获取IP信息1

post_data={"ip":ip,"accessKey":"alibaba-inc"}
ret_ipinfo= {}
try:
return_data=requests.post(taobaoIp_url,post_data)
#其中返回数据中code的值的含义为，0：成功，1：服务器异常，2：请求参数异常，3：服务器繁忙，4：个人qps超出
return_json=json.loads(return_data.text)
if return_json['code']==0:
ret_ipinfo['ip']=return_json['data']['ip']

ret_ipinfo['source']='淘宝IP'
addIPInfo2DB(ret_ipinfo)
except Exception as e:
print('未知错误 %s' % (e))
return ret_ipinfo

with geoip2.database.Reader(dbdir) as reader:
response = reader.city(ip)
ipinfo['ip'] =ip
ipinfo['country'] = response.country.names['zh-CN']
ipinfo['region'] =''
ipinfo['city']=response.city.name
ipinfo['org'] =''
ipinfo['loc'] = str(response.location.latitude)+','+str(response.location.longitude)
ipinfo['timezone'] = response.location.time_zone
ipinfo['source'] = 'GeoIP'
addIPInfo2DB(ipinfo)
return ipinfo
四、搭建一个FLASK Web应用来查询聚合的域名、IP情报信息1、FLASK Web应用的工程组织2、配置数据及读取配置数据1）配置数据配置数据分别放在.env及.flaskenv中，其中.env放的是工程中用到的数据库链接等比较私密的配置信息。.flaskenv放的是Flask运行环境的信息.env的配置信息参考如下：1

DEV_DATABASE_URI = 'mysql+pymysql://dbuser:[email protected]:3306/infocol_db_dev?charset=utf8'
TEST_DATABASE_URI = 'mysql+pymysql://dbuser:[email protected]:3306/infocol_db_test?charset=utf8'
PROD_DATABASE_URI = 'mysql+pymysql://dbuser:[email protected]:3306/infocol_db?charset=utf8'

SQLALCHEMY_TRACK_MODIFICATIONS = True
SECRET_KEY=your secret key
.falskenv配置信息参考如下：1
FLASK_ENV=development
2）实现读取配置数据通过config.py实现配置数据的读取及管理1

flaskenv_path=os.path.join(basedir,'.flaskenv')
env_path=os.path.join(basedir,'.env')
if os.path.exists(flaskenv_path):
load_dotenv(flaskenv_path)
if os.path.exists(env_path):
load_dotenv(env_path)

class Config:
geoLiteDBdir=os.path.join(basedir,'GeoLite2\GeoLite2-City.mmdb')
flaskenv = os.getenv('FLASK_ENV','development')
SECRET_KEY=os.getenv('SECRET_KEY','123!@#')
SQLALCHEMY_TRACK_MODIFICATIONS=os.getenv('SQLALCHEMY_TRACK_MODIFICATIONS')
SQLALCHEMY_DATABASE_URI = os.getenv('DEV_DATABASE_URI')
@staticmethod
def init_app(app):
pass

class DevelopmentConfig(Config):
DEBUG=True
SQLALCHEMY_DATABASE_URI = os.getenv('DEV_DATABASE_URI')

class TestingConfig(Config):
TESTING=True
SQLALCHEMY_DATABASE_URI = os.getenv('TEST_DATABASE_URI')

class ProductionConfig(Config):
SQLALCHEMY_DATABASE_URI = os.getenv('PROD_DATABASE_URI')

config={
'development':DevelopmentConfig,
'testing':TestingConfig,
'production':ProductionConfig,
'default':DevelopmentConfig
}
3、界面及路由界面很简单就一个域名/IP的输入框，输入域名或IP后去查询相应的域名信息或IP信息显示到界面上。界面用jinjia2的模板index.html代码如下：1

路由配置处理中实现了获取表单中的信息，并判断是域名还是IP如果是域名者获取whois信息，并根据域名获取IP信息。如果输入的是IP则获取IP信息，并反馈到页面上。1
