conn=httplib.HTTPConnection("www.cnblogs.com")

conn.request("GET","/coderzh/archive/2008/05/13/1194445.html")

r=conn.getresponse()

printr.read()#获取所有内容

importsmtplib

smtpServer='smtp.xxx.com'

fromaddr='foo@xxx.com'

server=smtplib.SMTP(smtpServer)

server.sendmail(fromaddr,toaddrs,msg)

server.quit()
