基于python的邮件发送代码

基于python的邮件发送代码

1、本地已安装smtp服务,如sendmail等:

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

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

sender = 'from@runoob.com'
receivers = ['429240967@qq.com']  # 接收邮件,可设置为你的QQ邮箱或者其他邮箱

# 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...', 'plain', 'utf-8')
message['From'] = Header("菜鸟教程", 'utf-8')   # 发送者
message['To'] =  Header("测试", 'utf-8')        # 接收者

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


try:
   smtpObj = smtplib.SMTP('localhost')
   smtpObj.sendmail(sender, receivers, message.as_string())
   print "邮件发送成功"
except smtplib.SMTPException:
   print "Error: 无法发送邮件"

2、使用第三方提供的SMTP服务

2.1 案例一:
#!/usr/bin/python
#coding:utf-8
import smtplib
from email.mime.text import MIMEText
import sys
mail_host = 'smtp.163.com'
mail_user = 'test@163.com'
mail_pass = 'your_mail_password'
mail_postfix = '163.com'
def send_mail(to_list,subject,content):
   me = "zabbix 监控告警平台"+"<"+mail_user+"@"+mail_postfix+">"
   msg = MIMEText(content, 'plain', 'utf-8')
   msg['Subject'] = subject
   msg['From'] = me
   msg['to'] = to_list
   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])

说明:该脚本会调用第三方的邮箱账户,需要你填写正确的mail_host, mail_user以及mail_pass。假如脚本名字为mail.py,则发邮件的命令为:

python  mail.py aming@aminglinux.com "邮件主题" "邮件内容"
2.2 案例二:
#!/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.XXX.com"  #设置服务器
mail_user="XXXX"    #用户名
mail_pass="XXXXXX"   #口令


sender = 'from@runoob.com'
receivers = ['429240967@qq.com']  # 接收邮件,可设置为你的QQ邮箱或者其他邮箱

message = MIMEText('Python 邮件发送测试...', 'plain', 'utf-8')
message['From'] = Header("菜鸟教程", 'utf-8')
message['To'] =  Header("测试", 'utf-8')

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


try:
   smtpObj = smtplib.SMTP()
   smtpObj.connect(mail_host, 25)    # 25 为 SMTP 端口号
   smtpObj.login(mail_user,mail_pass)  
   smtpObj.sendmail(sender, receivers, message.as_string())
   print "邮件发送成功"
except smtplib.SMTPException:
   print "Error: 无法发送邮件"

3、使用Python发送HTML格式的邮件

Python发送HTML格式的邮件与发送纯文本消息的邮件不同之处就是将MIMEText中_subtype设置为html。具体代码如下:

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

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

sender = 'from@runoob.com'
receivers = ['429240967@qq.com']  # 接收邮件,可设置为你的QQ邮箱或者其他邮箱

mail_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>
"""
message = MIMEText(mail_msg, 'html', 'utf-8')
message['From'] = Header("菜鸟教程", 'utf-8')
message['To'] =  Header("测试", 'utf-8')

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


try:
   smtpObj = smtplib.SMTP('localhost')
   smtpObj.sendmail(sender, receivers, message.as_string())
   print "邮件发送成功"
except smtplib.SMTPException:
   print "Error: 无法发送邮件"

4、Python 发送带附件的邮件

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。

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

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

sender = 'from@runoob.com'
receivers = ['429240967@qq.com']  # 接收邮件,可设置为你的QQ邮箱或者其他邮箱

#创建一个带附件的实例
message = MIMEMultipart()
message['From'] = Header("菜鸟教程", 'utf-8')
message['To'] =  Header("测试", 'utf-8')
subject = 'Python SMTP 邮件测试'
message['Subject'] = Header(subject, 'utf-8')

#邮件正文内容
message.attach(MIMEText('这是菜鸟教程Python 邮件发送测试……', 'plain', 'utf-8'))

# 构造附件1,传送当前目录下的 test.txt 文件
att1 = MIMEText(open('test.txt', 'rb').read(), 'base64', 'utf-8')
att1["Content-Type"] = 'application/octet-stream'
# 这里的filename可以任意写,写什么名字,邮件中显示什么名字
att1["Content-Disposition"] = 'attachment; filename="test.txt"'
message.attach(att1)

# 构造附件2,传送当前目录下的 runoob.txt 文件
att2 = MIMEText(open('runoob.txt', 'rb').read(), 'base64', 'utf-8')
att2["Content-Type"] = 'application/octet-stream'
att2["Content-Disposition"] = 'attachment; filename="runoob.txt"'
message.attach(att2)

try:
   smtpObj = smtplib.SMTP('localhost')
   smtpObj.sendmail(sender, receivers, message.as_string())
   print "邮件发送成功"
except smtplib.SMTPException:
   print "Error: 无法发送邮件"

5、在 HTML 文本中添加图片

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

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

sender = 'from@runoob.com'
receivers = ['429240967@qq.com']  # 接收邮件,可设置为你的QQ邮箱或者其他邮箱

msgRoot = MIMEMultipart('related')
msgRoot['From'] = Header("菜鸟教程", 'utf-8')
msgRoot['To'] =  Header("测试", 'utf-8')
subject = 'Python SMTP 邮件测试'
msgRoot['Subject'] = Header(subject, 'utf-8')

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


mail_msg = """
<p>Python 邮件发送测试...</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>
"""
msgAlternative.attach(MIMEText(mail_msg, 'html', 'utf-8'))

# 指定图片为当前目录
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>')
msgRoot.attach(msgImage)

try:
   smtpObj = smtplib.SMTP('localhost')
   smtpObj.sendmail(sender, receivers, msgRoot.as_string())
   print "邮件发送成功"
except smtplib.SMTPException:
   print "Error: 无法发送邮件"

6、使用第三方 SMTP 服务发送

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

import smtplib
from email.mime.text import MIMEText
from email.utils import formataddr

my_sender='429240967@qq.com'    # 发件人邮箱账号
my_pass = 'xxxxxxxxxx'              # 发件人邮箱密码
my_user='429240967@qq.com'      # 收件人邮箱账号,我这边发送给自己
def mail():
   ret=True
   try:
       msg=MIMEText('填写邮件内容','plain','utf-8')
       msg['From']=formataddr(["FromRunoob",my_sender])  # 括号里的对应发件人邮箱昵称、发件人邮箱账号
       msg['To']=formataddr(["FK",my_user])              # 括号里的对应收件人邮箱昵称、收件人邮箱账号
       msg['Subject']="菜鸟教程发送邮件测试"                # 邮件的主题,也可以说是标题

       server=smtplib.SMTP_SSL("smtp.qq.com", 465)  # 发件人邮箱中的SMTP服务器,端口是25
       server.login(my_sender, my_pass)  # 括号中对应的是发件人邮箱账号、邮箱密码
       server.sendmail(my_sender,[my_user,],msg.as_string())  # 括号中对应的是发件人邮箱账号、收件人邮箱账号、发送邮件
       server.quit()  # 关闭连接
   except Exception:  # 如果 try 中的语句没有执行,则会执行下面的 ret=False
       ret=False
   return ret

ret=mail()
if ret:
   print("邮件发送成功")
else:
   print("邮件发送失败")
