Python实现读取邮箱中的邮件功能示例【含文本及附件】

本文实例讲述了Python实现读取邮箱中的邮件功能。分享给大家供大家参考，具体如下：

#-*- encoding: utf-8 -*-
import sys
import locale
import poplib
from email import parser
import email
import string
# 确定运行环境的encoding
__g_codeset = sys.getdefaultencoding()
if "ascii"==__g_codeset:
  __g_codeset = locale.getdefaultlocale()[1]
#
def object2double(obj):
  if(obj==None or obj==""):
    return 0
  else:
    return float(obj)
  #end if
#
def utf8_to_mbs(s):
  return s.decode("utf-8").encode(__g_codeset)
#
def mbs_to_utf8(s):
  return s.decode(__g_codeset).encode("utf-8")
#
host = 'pop.exmail.qq.com'
username = 'user1@xxxx.cn'
password = 'password'
pop_conn = poplib.POP3_SSL(host)
pop_conn.user(username)
pop_conn.pass_(password)
#Get messages from server:
# 获得邮件
messages = [pop_conn.retr(i) for i in range(1, len(pop_conn.list()[1]) + 1)]
#print messages
#print "--------------------------------------------------"
# Concat message pieces:
messages = ["\n".join(mssg[1]) for mssg in messages]
#print messages
#Parse message intom an email object:
# 分析
messages = [parser.Parser().parsestr(mssg) for mssg in messages]
i = 0
for index in range(0,len(messages)):
  message = messages[index];
  i = i + 1;
  subject = message.get('subject')
  h = email.Header.Header(subject)
  dh = email.Header.decode_header(h)
  subject = unicode(dh[0][0], dh[0][1]).encode('utf8')
  mailName = "mail%d.%s" % (i, subject)
  f = open('%d.log'%(i), 'w');
  print >> f, "Date: ", message["Date"]
  print >> f, "From: ", email.utils.parseaddr(message.get('from'))[1]
  print >> f, "To: ", email.utils.parseaddr(message.get('to'))[1]
  print >> f, "Subject: ", subject
  print >> f, "Data: "
  j = 0
  for part in message.walk():
    j = j + 1
    fileName = part.get_filename()
    contentType = part.get_content_type()
    mycode=part.get_content_charset();
    # 保存附件
    if fileName:
      data = part.get_payload(decode=True)
      h = email.Header.Header(fileName)
      dh = email.Header.decode_header(h)
      fname = dh[0][0]
      encodeStr = dh[0][1]
      if encodeStr != None:
        fname = fname.decode(encodeStr, mycode)
      #end if
      fEx = open("%s"%(fname), 'wb')
      fEx.write(data)
      fEx.close()
    elif contentType == 'text/plain':# or contentType == 'text/html':
      #保存正文
      data = part.get_payload(decode=True)
      content=str(data);
      if mycode=='gb2312':
        content= mbs_to_utf8(content)
      #end if
      nPos = content.find('降息')
      print("nPos is %d"%(nPos))
      print >> f, data
    #end if
  #end for
  f.close()
#end for
pop_conn.quit()
