本文实例讲述了python中django框架通过正则搜索页面上email地址的方法。分享给大家供大家参考。具体实现方法如下：

import re
from django.shortcuts import render
from pattern.web import URL, DOM, abs, find_urls
def index(request):
 \"\"\"
 find email addresses in requested url or contact page
 \"\"\"
 error = \'\'
 emails = set()
 url_string = request.GET.get(\'url\', \'\')
 EMAIL_REGEX = re.compile(r\'[A-Z0-9._%+-]+@[A-Z0-9.-]+\\.[A-Z]{2,6}\', re.IGNORECASE)
 # use absolute url or domain name
 url = URL(url_string) if url_string.startswith(\'http\') else URL(domain=url_string,protocol=\'http\')
 if url_string:
  try:
   dom = DOM(url.download(cached=True))
  except Exception, e:
   error = e
  else:
   contact_urls = { url.string }
   # search links of contact page
   for link in dom(\'a\'):
    if re.search(r\'contact|about\', link.source, re.IGNORECASE):
     contact_urls.add(
      abs(link.attributes.get(\'href\',\'\'), base=url.redirect or url.string))
   for contact_url in contact_urls:
    # download contact page
    dom = DOM(URL(contact_url).download(cached=True))
    # search emails in the body of the page
    for line in dom(\'body\')[0].content.split(\'\\n\'):
     found = EMAIL_REGEX.search(line)
     if found:
      emails.add(found.group())
 data = {
  \'url\': url_string,
  \'emails\': emails,
  \'error\': error,
 }
 return render(request, \'index.html\', data)

希望本文所述对大家的Python程序设计有所帮助。
