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-*-
importsys
importlocale
importpoplib
fromemailimportparser
importemail
importstring
#确定运行环境的encoding
__g_codeset=sys.getdefaultencoding()
if"ascii"==__g_codeset:
__g_codeset=locale.getdefaultlocale()[1]
#
defobject2double(obj):
if(obj==Noneorobj==""):
return0
else:
returnfloat(obj)
#endif
#
defutf8_to_mbs(s):
returns.decode("utf-8").encode(__g_codeset)
#
defmbs_to_utf8(s):
returns.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)
#Getmessagesfromserver:
#获得邮件
messages=[pop_conn.retr(i)foriinrange(1,len(pop_conn.list()[1])+1)]
#printmessages
#print"--------------------------------------------------"
#Concatmessagepieces:
