刷票一般要突破以下限制：
1、验证码识别
2、同一ip不可连续投票
?
解决办法
1、用tesseract工具，链接在此 https://code.google测试数据/p/tesseract-ocr/?(人人还是加不了https链接)
2、使用代理，国内可以的代理服务器可以从这里找到?http://cn-proxy测试数据/
程序语言当然用python
浏览器投票的流程如下
1、向服务器发送请求，服务器返回验证码和表单
2、填好表单，发送到服务器
可以用firefox+httpfox插件查看整个事件过程，以及发送请求的POST和GET数据格式
使用python的urllib2库实现上述过程
1、向服务器请求验证码
可以用
+BEGIN ?python
import urllib
urllib.urlretrieve(imgurl,imgfile)#imgurl可以从页面源代码找到
+END
但是由于每次请求服务器，都会重新生成验证码，所以这样请求道的验证码即便识别出来，再POST进去时也会提示错误。解决办法时使用cookie
+BEGIN ?python
import cookie
import urllib2
cookiejar=cookielib.MozillaCookieJar(cookieFilename)
opener=urllib2.build_opener(urllib2.HTTPCookieProcessor(cookiejar))
response=opener.open(imgurl)
+END
如果需要使用代理服务器，则可以这样写
+BEGIN ?python
import cookie
import urllib2
proxy_line='127.0.0.1:8087'
cookieFilename='cookie.txt'
cookiejar=cookielib.MozillaCookieJar(cookieFilename)
opener=urllib2.build_opener(urllib2.ProxyHandler({'http':proxy_line}),urllib2.HTTPCookieProcessor(cookieFileJar))
response=opener.open(imgurl,timeout=2)#设置超时时间
+END
这样就是以本机8087端口带有cookie验证访问服务器，下一步识别出验证码，依然带cookie POST进服务器即可。
2、保存验证码到本地
上面response即返回得到的验证码二进制流，写入文件用下面代码
+BEGIN ?python
content=response.read()
fp=file(imgfile,'wb')#将二进制图片保存
fp.write(content)
fp.close()
+END
3、验证码识别
验证码识别用tesseract，由于tesseract没有提供python接口，这里用系统调用外部命令
用法为
+BEGIN python
import os imgfile='img.jpg'
out
