python发送带附件的邮件

今天面要用将gradle打包的apk邮件发送给某些成员,jenkins自带的邮件没有这个功能，我就想自己实现一个以备后用，于是还是用我喜欢的python实现了一个：

首先习惯性的写配置：创建一个settings.py文件

# -*-coding:utf-8 -*-
import os

#邮件配置
EMAIL = {
'host': 'smtp.mailgun.org', #邮件服务器地址
'user': 'xxxx@qq.com', #发件用户名
'port': 587,
'password': 'xxxxxx', #发件人密码
'nickname': '牛B的管理员',
'mail_debug': True,
'mail_ssl':True
}

然后就是邮件发送的实现方法：

# -*-coding:utf-8 -*-

import settings
import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEBase
from email.mime.multipart import MIMEMultipart
import mimetypes
from email import encoders
import os
import time

# 发送带附件的邮件
def ToMail(mailto, subject, body, attachments='',  format='plain'):
'''
:param mailto: 发送邮件对象（发送人），可以为列表或字符串
:param subject: 邮件标题
:param body: 邮件主体内容
:param attachments: 邮件附件
:param format: 邮件页面对像
:return: True or False
'''
if isinstance(body, unicode):
body = str(body)
me= settings.EMAIL.get('nickname') + "<"+settings.EMAIL.get('user')+">"
msg = MIMEMultipart()
bo = MIMEText(body, format, 'utf-8')
if not isinstance(subject, unicode):
subject = str(subject)
if isinstance(mailto, list):
msg['To'] = ";".join(mailto)
else:
msg['To'] = mailto
msg.attach(bo)
msg['Subject'] = subject
msg['From'] = me
msg["Accept-Language"]="zh-CN"
msg["Accept-Charset"]="ISO-8859-1,utf-8"
#****************************************
#载入附件
if isinstance(attachments, list):
for file in attachments:
data = open(file.decode('utf-8').encode('gbk'), 'rb')
ctype,encoding = mimetypes.guess_type(file)
if ctype is None or encoding is not None:
ctype = 'application/octet-stream'
maintype,subtype = ctype.split('/',1)
file_msg = MIMEBase(maintype, subtype)
file_msg.set_payload(data.read())
data.close()
encoders.encode_base64(file_msg)
#***************************************************************
# 如果附件名称含有中文, 则 filename 要转换为gb2312编码, 否则就会出现乱码.basename.decode('utf-8').encode('gb2312')
filename = os.path.basename(file)
file_msg.add_header('Content-Disposition', 'attachment; filename="%s"' % filename.decode('utf8').encode('gb2312'))
msg.attach(file_msg)
try:
server = smtplib.SMTP(settings.EMAIL.get('host'),
port=settings.EMAIL.get('port'),
timeout=30)
server.debuglevel=settings.EMAIL.get('mail_debug')
if settings.EMAIL.get('mail_ssl'):
server.starttls()
server.login(settings.EMAIL.get('user'),
settings.EMAIL.get('password'))
server.sendmail(me, mailto, msg.as_string())
return True
finally:
server.close()
return False

#**************************************************
#由于使用的国外的邮件服务器，有些不稳定所以给予三次重发机会
a = 0
while True:
a+= 1
if a <= 3:
status = ToMail(['ffffff@qq.com'],
'aaaaaaaaaaaa',
'aaaaaaaaaaaaa',
attachments=['G:/xxx/xxx/xxxxxx.apk'])
if status:
break

time.sleep(1)
