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)
