解决python发送邮件乱码

一.邮件主题乱码

1.打开python的Lib文件夹下的 mimetypes.py 文件，找到大概256行的

‘default_encoding = sys.getdefaultencoding()’。

在这行前面添加三行，并且注释4行代码

#try:
#    ctype = ctype.encode(default_encoding) # omit in 3.x!
#except UnicodeEncodeError:
#    pass
else:
yield ctype
i += 1

if sys.getdefaultencoding() != 'gbk':
reload(sys)
sys.setdefaultencoding('gbk')
default_encoding = sys.getdefaultencoding()

2.在代码中加入下面片段

reload(sys)
sys.setdefaultencoding('gb18030')

二.邮件内容乱码

在代码中对内容做如下处理

msg = MIMEText(content,format,'gbk')

三.详细发送邮件代码

#!/usr/bin/python
#coding:utf-8

import smtplib
from email.mime.text import MIMEText
import sys

#邮箱服务器地址
mail_host = 'smtp.163.com'
#邮箱用户名
mail_user = 'XXX'
#邮箱密码
mail_pass = 'XXX'
mail_postfix = '163.com'

def send_mail(to_list,subject,content):
format='plain'
me = mail_user+"<"+mail_user+"@"+mail_postfix+">"
msg = MIMEText(content,format,'gbk')
reload(sys)
sys.setdefaultencoding('gb18030')
if not isinstance(subject,unicode):
subject = unicode(subject)
msg['Subject'] = subject
msg['From'] = me
msg['to'] = to_list
msg['Accept-Language']='zh-CN'
msg['Accept-Charset']='ISO-8859-1,utf-8'

try:
s = smtplib.SMTP()
s.connect(mail_host)
s.login(mail_user,mail_pass)
s.sendmail(me,to_list,msg.as_string())
s.close()
return True
except Exception,e:
print str(e)
return False

if __name__ == "__main__":
send_mail(sys.argv[1], sys.argv[2], sys.argv[3])

四.收发件人中文乱码

五.测试邮件发送

python email_test.py 'XXX@qq.com' '测试邮件' '这个邮件是测试用'
