Python发送邮件

使用email模块和smtplib模块,内容比较固定,配好了即可实现,代码如下:

一、普通邮件发送
import smtplib
from email.mime.text import MIMEText
email_host = 'smtp.163.com' #邮箱地址
email_user = 'XXX@163.com' # 发送者账号
email_pwd = 'XXX' # 发送者的密码
maillist ='XXX@XXXX.com'
#收件人邮箱,多个账号的话,用逗号隔开
me = email_user
msg = MIMEText('这是个python测试邮件,不用回复。') # 邮件内容
msg['Subject'] = 'python测试' # 邮件主题
msg['From'] = me # 发送者账号
msg['To'] = maillist # 接收者账号列表
smtp = smtplib.SMTP(email_host,port=25) # 连接邮箱,传入邮箱地址,和端口号,smtp的端口号是25
smtp.login(email_user, email_pwd) # 发送者的邮箱账号,密码
smtp.sendmail(me, maillist, msg.as_string())
# 参数分别是发送者,接收者,第三个是把上面的发送邮件的内容变成字符串
smtp.quit() # 发送完毕后退出smtp
print ('email send success.')

注意
1. 发送者密码这里不是平时登录邮箱的密码,而是开启登录第三方邮件客户端的授权码。
2. 多数邮箱的smtp的端口号都是25,个别的请具体确认。


发邮件的代码封装成函数:

import smtplib
from email.mime.text import MIMEText


def send_mail(username, passwd, recv, title, content, mail_host='smtp.163.com', port=25):
'''
发送邮件函数,默认使用163smtp
:param username: 邮箱账号 xx@163.com
:param passwd: 邮箱密码
:param recv: 邮箱接收人地址,多个账号以逗号隔开
:param title: 邮件标题
:param content: 邮件内容
:param mail_host: 邮箱服务器
:param port: 端口号
:return:
'''
msg = MIMEText(content) # 邮件内容
msg['Subject'] = title # 邮件主题
msg['From'] = username # 发送者账号
msg['To'] = recv # 接收者账号列表
smtp = smtplib.SMTP(mail_host, port=port) # 连接邮箱,传入邮箱地址,和端口号,smtp的端口号是25
smtp.login(username, passwd) # 发送者的邮箱账号,密码
smtp.sendmail(username, recv, msg.as_string())
# 参数分别是发送者,接收者,第三个是把上面的发送邮件的内容变成字符串
smtp.quit() # 发送完毕后退出smtp
print('email send success.')


email_user = 'xxxx@163.com' # 发送者账号
email_pwd = 'xxxxx' # 发送者密码
maillist = 'XXX@XXX.com'
title = '测试邮件标题'
content = '这里是邮件内容'
send_mail(email_user, email_pwd, maillist, title, content)

二、发带附件的邮件

import smtplib
#smtplib这个模块是管发邮件
from email.mime.text import MIMEText
#构造邮件内容
from email.mime.multipart import MIMEMultipart
#发带附件的邮件用的
email_host = 'smtp.163.com' #邮箱服务器地址
email_user = 'XXX@163.com' # 发送者账号
email_pwd = 'XXX'
# 发送者密码是邮箱的授权码,不是登录的密码
maillist = 'XXX@XXX.com'
#收件人邮箱,多个账号的话,用逗号隔开
new_msg = MIMEMultipart()
#构建了一个能发附件的邮件对象
new_msg.attach(MIMEText('这是Python测试发邮件的邮件,不要回复'))
# 邮件内容
new_msg['Subject'] = 'Python测试邮件带附件' # 邮件主题
new_msg['From'] = email_user # 发送者账号
new_msg['To'] = maillist # 接收者账号列表
att = MIMEText(open('like_report.txt').read())
att["Content-Type"] = 'application/octet-stream'
att["Content-Disposition"] = 'attachment; filename="haha.txt"'
new_msg.attach(att)
smtp = smtplib.SMTP(email_host,port=25) # 连接邮箱,传入邮箱地址,和端口号,smtp的端口号是25
smtp.login(email_user, email_pwd) # 发送者的邮箱账号,密码
smtp.sendmail(email_user, maillist, new_msg.as_string())
# 参数分别是发送者,接收者,第三个是把上面的发送邮件的内容变成字符串
smtp.quit() # 发送完毕后退出smtp
print ('email send success.')

三、封装发送邮件的类并验证

class SendMail(object):
def __init__(self,username,passwd,recv,title,content,
file=None,
email_host='smtp.163.com',port=25):
self.username = username
self.passwd = passwd
self.recv = recv
self.title = title
self.content = content
self.file = file
self.email_host = email_host
self.port = port
def send_mail(self):
msg = MIMEMultipart()
#发送内容的对象
if self.file:#处理附件的
att = MIMEText(open(self.file).read())
att["Content-Type"] = 'application/octet-stream'
att["Content-Disposition"] = 'attachment; filename="%s"'%self.file
msg.attach(att)
msg.attach(MIMEText(self.content))#邮件正文的内容
msg['Subject'] = self.title # 邮件主题
msg['From'] = self.username # 发送者账号
msg['To'] = self.recv # 接收者账号列表
self.smtp = smtplib.SMTP(self.email_host,port=self.port)
#发送邮件服务器的对象
self.smtp.login(self.username,self.passwd)
try:
self.smtp.sendmail(self.username,self.recv,msg.as_string())
except Exception as e:
print('出错了。。',e)
else:
print('发送成功!')
def __del__(self):
self.smtp.quit()

if __name__ == '__main__':
m = SendMail(
username='XXX@163.com',passwd='XXX',recv='XXX@XXX.com',
title='新鞋的发送邮件',content='哈哈哈啊哈哈哈哈',file='like_report.txt'
)
m.send_mail()
