python發送郵件樣本(支援中文郵件標題)

代碼如下:

def sendmail(login={},mail={}):
'''\
@param login login['user'] login['passwd']
@param mail mail['to_addr'] mail['subject'] mail['content'] mail['attach']
'''
from datetime import datetime
from base64 import b64encode
import smtplib, mimetypes
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.mime.image import MIMEImage

user_info = login['user'].split('@')
mail_configure = {}
mail_configure['mail_encoding'] = 'utf-8'
mail_configure['mail_supplier'] = user_info[1]
mail_configure['from_addr'] = login['user']
mail_configure['server_host'] = 'smtp.%s' % mail_configure['mail_supplier']
error = None

try:
email = MIMEMultipart()
email['from'] = mail_configure['from_addr']
email['to'] = mail['to_addr']
email['subject'] = '=?%s?B?%s?=' % (mail_configure['mail_encoding'],b64encode(mail['subject']))
email_content = MIMEText(mail['content'], _charset=mail_configure['mail_encoding'])
email.attach(email_content)

if 'attach' in mail:
for i in mail['attach']:
ctype, encoding = mimetypes.guess_type(i)
if ctype is None or not encoding is None:
ctype = 'application/octet-stream'
maintype, subtype = ctype.split('/', 1)
att = MIMEImage((lambda f: (f.read(), f.close()))(open(i, 'rb'))[0], _subtype = subtype)
att.add_header('Content-Disposition', 'attachment', filename = i)
email.attach(att)

smtp = smtplib.SMTP()
smtp.connect(mail_configure['server_host'])
smtp.login(user_info[0], login['passwd'])
smtp.sendmail(mail_configure['from_addr'], mail['to_addr'], email.as_string())
smtp.quit()
except Exception as e:
error = e

return (mail_configure['from_addr'], mail['to_addr'], error)

測試

代碼如下:

def t21():
login = {
'user':'ak43@sina.com',
'passwd':'hello@d'
}
mail = {
'to_addr':'ak32@sina.com;ak32@21cn.com',
'subject':'不帶附件的測試郵件',
'content':'''\
sz002718,友邦吊頂
sz002719,麥趣爾
sz002722,金輪股份
''',
}
print sendmail(login, mail)

login = {
'user':'hellot@sina.com',
'passwd':'hello#world'
}
mail = {
'to_addr':'tom12@sina.com;tom12@21cn.com',
'subject':'帶附件的測試郵件',
'content':'''\
sz002718,友邦吊頂
sz002719,麥趣爾
sz002722,金輪股份
''',
'attach':['e:/a/a.txt']
}
print sendmail(login, mail)
