python 模仿web页面检测域名是否被注册

lx86

最近在给朋友弄个网站，网站基本弄好以后就要申请个域名，以前也接触过域名注册的，这次想真个拉风点的域名，结果。。。令人大失所望。
在不断重复的提交后，发现可以弄个程序检测一下有没有好点的域名，这样就不用人为输入域名了。然后就有了 下面的代码。

#!/bin/env python
#coding=gbk
import urllib
import urllib2
import time
'''关键字构造'''
def analysis(radix,keyword,lenSize):
global res_f
global res_e
if radix==10:
if keyword<radix:
res_f.append(keyword)
else:
res_f.append(keyword%radix)
analysis(radix,keyword/radix,lenSize)
else:
if keyword<radix:
res_e.append(keyword)
else:
res_e.append(keyword%radix)
analysis(radix,keyword/radix,lenSize)
'''form表单提交的地址，不好意思啊请求了几十万次'''
url = 'http://www.7data.com/domain_reg/'
'''域名中字符串的长度'''
chars_length = 3
'''域名中数字的长度'''
numbers_length = 1
print('auto check begin')
total_chars = 26**chars_length
total_numbers = 10**numbers_length
total_index = total_numbers*total_chars
i = 7
j = 26*26*11
'''这层循环是 对数字的遍历'''
while i<=7:
res_f=[]
analysis(10,i,numbers_length)
domain_f = ''
c = numbers_length-len(res_f)
index_1 = 0
'''这层循环是对英文字母的遍历'''
while index_1<c:
res_f.insert(len(res_f), 0)
index_1=index_1+1

for res_f_str in res_f:
domain_f=str(res_f_str)+domain_f
#print (domain_f)
while j<=total_chars:
res_e=[]
analysis(26,j,chars_length)
index_2 = 0
c2 = chars_length-len(res_e)
while index_2<c2:
res_e.insert(len(res_e), 0)
index_2=index_2+1
domain_e = ''
#print res_e
for res_e_str in res_e:
domain_e = chr(res_e_str+97)+domain_e
#print (j,':',domain_e)
'''要注册的域名'''
domainname=domain_e+domain_f
#domainname=domain_e
time.sleep(0.1)
values = {'module':'domainsearch','vrf':'','searchType':'IntDomain','action':'check','searchedDomainName':domainname,'suffix':'.com','imageField2.x':'41','imageField2.y':'17'}
data = urllib.urlencode(values)
req = urllib2.Request(url, data)
try:
#response=''
response = urllib2.urlopen(req)
except Exception,e:
print (Exception,'domain:',domainname,e)

hasResistflag = True
'''判断是否成功'''
for line in response:
if line.find('yes.jpg')>0:
hasResistflag=False
break
if not hasResistflag:
print(time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(time.time())),'index:',j,'domains:',domainname,' --------------can regist--------------')
else:
print(time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(time.time())),'index:',j,'domains:',domainname,' can not regist')

j=j+1
i=i+1
print('auto check end')
