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 = '[email protected]'

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()

希望本文所述对大家Python程序设计有所帮助。
