python实现邮件自动发送


						本文实例为大家分享了python实现邮件自动发送的具体代码，供大家参考，具体内容如下

case 1：纯文本和HTML文件发送





# -*- coding: UTF-8 -*-





import smtplib

import traceback

from email.mime.text import MIMEText

from email.mime.multipart import MIMEMultipart



def sendmail(subject,msg,toaddrs,fromaddr,smtpaddr,password):

 '''

 @subject:邮件主题

 @msg:邮件内容

 @toaddrs:收信人的邮箱地址

 @fromaddr:发信人的邮箱地址

 @smtpaddr:smtp服务地址，可以在邮箱看，比如163邮箱为smtp.163.com

 @password:发信人的邮箱密码

 '''



 mail_msg = MIMEMultipart()

 if not isinstance(subject,unicode): #过滤或者不过滤貌似没啥影响

  subject = unicode(subject, 'utf-8')

 mail_msg['Subject'] = subject

 mail_msg['From'] =fromaddr

 mail_msg['To'] = ','.join(toaddrs)

 mail_msg.attach(MIMEText(msg, 'plain', 'utf-8')) #f发送文本文件

 #mail_msg.attach(MIMEText(msg, 'html', 'utf-8')) #发送html格式邮件

 try:

  s = smtplib.SMTP()

  s.connect(smtpaddr) #连接smtp服务器

  s.login(fromaddr,password) #登录邮箱

  s.sendmail(fromaddr, toaddrs, mail_msg.as_string()) #发送邮件

  s.quit()

  print "邮件发送成功！"

 except Exception,e:

  print "Error: unable to send email"

  print traceback.format_exc()





if __name__ == '__main__':

 fromaddr = "h******m@126.com"

 smtpaddr = "smtp.126.com"

 toaddrs = ["83****789@qq.com","h******m@126.com"]

 subject = "Hello,我是邮件主题"

 password = "不能告诉你"

 #msg = "Hello,我是邮件内容 !!!"

 msg="""

 <p>Python 邮件发送测试...</p>

 <p><a href="http://www.runoob.com" >这是一个链接</a></p>

 """

 sendmail(subject,msg,toaddrs,fromaddr,smtpaddr,password)



case 2.添加附件：发送带附件的邮件，首先要创建MIMEMultipart()实例，然后构造附件，如果有多个附件，可依次构造，最后利用smtplib.smtp发送。





# -*- coding: UTF-8 -*-



# 如何添加附件

import os





import smtplib

import traceback

from email.mime.text import MIMEText

from email.mime.multipart import MIMEMultipart

os.chdir("C:\\Users\\h****m\\Desktop\\Auto_email")





def sendmail(subject,msg,toaddrs,fromaddr,smtpaddr,password):

 '''

 @subject:邮件主题

 @msg:邮件内容

 @toaddrs:收信人的邮箱地址

 @fromaddr:发信人的邮箱地址

 @smtpaddr:smtp服务地址，可以在邮箱看，比如163邮箱为smtp.163.com

 @password:发信人的邮箱密码

 '''





 mail_msg = MIMEMultipart()

 if not isinstance(subject,unicode): #过滤或者不过滤貌似没啥影响

  subject = unicode(subject, 'utf-8')

 mail_msg['Subject'] = subject

 mail_msg['From'] =fromaddr

 mail_msg['To'] = ','.join(toaddrs)

 #mail_msg.attach(MIMEText(msg, 'plain', 'utf-8')) #f发送文本文件

 mail_msg.attach(MIMEText(msg, 'html', 'utf-8')) #发送html格式邮件

 

 #构造附件1

 att1=MIMEText(open("test_file1.txt",'rb').read(),'base64','utf-8') #注意：直接读取中文文件名会报错 

 att1["Content-Type"] = 'application/octet-stream'

 att1["Content-Disposition"] = 'attachment; filename="test_file1.txt"'

 mail_msg.attach(att1)

 

 

 #构造附件2：添加中文附件名

 att2=MIMEText(open(u'测试文件2.docx','rb').read(),'base64','utf-8')

 att2["Content-Type"] = 'application/octet-stream'

 att2["Content-Disposition"] = 'attachment; filename="test_file2.docx"'

 mail_msg.attach(att2)

 

 try:

  s = smtplib.SMTP()

  s.connect(smtpaddr) #连接smtp服务器

  s.login(fromaddr,password) #登录邮箱

  s.sendmail(fromaddr, toaddrs, mail_msg.as_string()) #发送邮件

  s.quit()

  print "邮件发送成功！"

 except Exception,e:

  print "Error: unable to send email"

  print traceback.format_exc()





if __name__ == '__main__':

 fromaddr = "h****m@126.com"

 smtpaddr = "smtp.126.com"

 toaddrs = ["83****789@qq.com","h****m@126.com"]

 subject = "Hello,我是邮件主题"

 password = "不能告诉你"

 #msg = "Hello,我是邮件内容 !!!"

 msg="""

 <p>Python 邮件发送测试...</p>

 <p><a href=http://www.runoob.com >这是一个链接</a></p>

 """

 sendmail(subject,msg,toaddrs,fromaddr,smtpaddr,password)



case 3: 发送图片(容易被判别为垃圾邮件，导致：SMTPDataError: (554, 'DT:SPM 126……错误)





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



fromaddr = "h****m@126.com"

smtpaddr = "smtp.126.com"

toaddrs = ["83****789@qq.com","h****m@126.com"]

subject = "Hello,我是邮件主题"

password = "不能告诉你"



#test3

msg = """

<p>Python 邮件发送添加图片测试...</p>

<p><a href="http://www.runoob.com" >菜鸟教程链接</a></p>

<p>图片演示：</p>

<p><img src="cid:image1"></p>

"""



import os

import smtplib



from email.mime.text import MIMEText

from email.mime.multipart import MIMEMultipart

from email.mime.image import MIMEImage

os.chdir("C:\\Users\\h****m\\Desktop\\Auto_email")



msgRoot = MIMEMultipart('related')

if not isinstance(subject,unicode): #过滤或者不过滤貌似没啥影响

 subject = unicode(subject, 'utf-8')





msgRoot['Subject'] = subject

msgRoot['From'] =fromaddr

msgRoot['To'] = ','.join(toaddrs)





msgAlternative = MIMEMultipart('alternative')

msgRoot.attach(msgAlternative)



msg = """

<p>Python 邮件发送测试...</p>

<p>图片演示：</p>

<p><img src="cid:image1"></p>

"""

msgAlternative.attach(MIMEText(msg, 'html', 'utf-8'))





fp = open('test.PNG', 'rb')

msgImage = MIMEImage(fp.read())

fp.close()



# 定义图片 ID，在 HTML 文本中引用

msgImage.add_header('Content-ID', '<image1>')

msgRoot.attach(msgImage)



s = smtplib.SMTP()

s.connect(smtpaddr) #连接smtp服务器

s.login(fromaddr,password) #登录邮箱

s.sendmail(fromaddr, toaddrs, msgRoot.as_string()) #发送邮件

s.quit()

print "邮件发送成功！"



#邮件发送成功！



对于case3，发送很不稳定，时而发送得出，时而报 SMTPDataError: 554错误，等有空了，看有没有方法弄个稳定的版本。case1,case2在工作中基本够用了。
