使用python语言发送邮件smtp发送文本和添加附件

使用python语言发送邮件smtp，详细见下面脚本

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

import smtplib
from email.mime.text import MIMEText
from email.header import Header

# 第三方SMTP服务
mail_host = 'smtp.126.com'
mail_user = '[e-mail]'
mail_pass = '12345678'

sender = '[e-mail]'
receivers = ['[e-mail]']

# 三个参数： 第一个为文本内容，第二个plain设置文本格式 ，第三个utf-8设置编码
message = MIMEText('Python 邮件发送测试5。。。', 'plain', 'utf-8')
message['From'] = '[e-mail]'   #发送者
message['To'] = '[e-mail]'   #接收者

subject = 'Python 测试邮件5'
message['Subject'] = Header(subject, 'utf-8')


smtpObj = smtplib.SMTP()
smtpObj.connect(mail_host, 25)
smtpObj.login(mail_user, mail_pass)
smtpObj.sendmail(sender, receivers, message.as_string())
print "邮件发送成功"

注意上面的接收者可以随便填写，可以是数字字符 同时126邮箱要在设置里开通 邮箱授权密码

下面为添加附件的代码：、

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

import smtplib
import email
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.header import Header
from email.mime.image import MIMEImage
from email.mime.application import MIMEApplication

# 第三方SMTP服务
mail_host = 'smtp.126.com'
mail_user = '[e-mail]'
mail_pass = '888888'

sender = '[e-mail]'
receivers = ['[e-mail]']


#创建一个带附件的实例
message = MIMEMultipart()
message['From'] = '[e-mail]'   #发送者
message['To'] = 'weiruoyu魏若愚'   #接收者
# 邮件标题
subject = 'Python SMTP邮件测试带附件。。。'
message['Subject'] = Header(subject, 'utf-8')

#邮件正文内容
message.attach(MIMEText('python含有附件', 'plain', 'utf-8'))

#添加附件
part = MIMEApplication(open('test.txt', 'rb').read())
part.add_header('Content-Disposition', 'attachment', filename="test.txt")
message.attach(part)

#添加附件2
part = MIMEApplication(open('abc.docx', 'rb').read())
part.add_header('Content-Disposition', 'attachment', filename="abc.docx")
message.attach(part)

smtpObj = smtplib.SMTP()
smtpObj.connect(mail_host, 25)
smtpObj.login(mail_user, mail_pass)
smtpObj.sendmail(sender, receivers, message.as_string())
smtpObj.quit()

print "邮件发送成功"

上面的filename="test.txt"可以随便自定义的 参考：http://www.runoob.com/python/python-email.html 邮件附件代码参考：http://www.cppcns.com/jiaoben/python/191319.html

下面为添加图片的代码：

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

import smtplib
import email
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.header import Header
from email.mime.image import MIMEImage
from email.mime.application import MIMEApplication

# 第三方SMTP服务
mail_host = 'smtp.126.com'
mail_user = '[e-mail]'
mail_pass = '123456'

sender = '[e-mail]'
receivers = ['[e-mail]']

###########添加图片############

#创建一个带附件的实例
message = MIMEMultipart('related')
message['From'] = '[e-mail]'   #发送者
message['To'] = 'weiruoyu魏若愚'   #接收者
# 邮件标题
subject = 'Python SMTP邮件测试带图片。。。'
message['Subject'] = Header(subject, 'utf-8')

msgAlternative = MIMEMultipart('alternative')
message.attach(msgAlternative)

mail_msg = """
<p>Python 邮件发送测试。。。带图片的</p>
<p><a rel="nofollow" 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>
"""

#邮件正文内容
message.attach(MIMEText(mail_msg, 'html', 'utf-8'))

# 置顶图片为当前目录
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>')
message.attach(msgImage)

smtpObj = smtplib.SMTP()
smtpObj.connect(mail_host, 25)
smtpObj.login(mail_user, mail_pass)
smtpObj.sendmail(sender, receivers, message.as_string())
smtpObj.quit()

print "邮件发送成功"

如果是多个邮箱需要发送的话，只需要修改，

receivers = ['[e-mail]','[e-mail]']
message['To'] = ','.join(receivers)
