【Python】利用python自动发送邮件

前言

在训练网络的过程中，需要大量的时间，虽然可以预估网络训练完成时间，但蹲点看结果着实有点不太聪明的亚子。

因此，参照师兄之前发的python利用smtp自动发邮件的代码，我作了些调整，并参照网上的开源代码，整理出了加强版（可以传文件），这样训练的log还有model，或者是远程电脑上的文件都可以通过邮件即时到达接收邮件的邮箱_很方便吧~~

正文

废话不多说，直接上代码。

一、普通文本邮件（作通知训练结束用 ）

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

import smtplib
from email.mime.text import MIMEText

# 第三方 SMTP 服务
mail_host = "smtp.163.com"  # SMTP服务器
mail_user = "yourname"  # 用户名
mail_pass = "xxx"  # 密码(这里的密码不是登录邮箱密码，而是授权码)

sender = 'yourname@163.com'  # 发件人邮箱
receivers = ['othername@163.com']  # 接收人邮箱

content = 'Python Send Mail ! 训练结束！'
title = 'Python SMTP Mail 训练结束'  # 邮件主题

message = MIMEText(content, 'plain', 'utf-8')  # 内容, 格式, 编码
message['From'] = "{}".format(sender)
message['To'] = ",".join(receivers)
message['Subject'] = title

try:
    smtpObj = smtplib.SMTP_SSL(mail_host, 465)  # 启用SSL发信, 端口一般是465
    smtpObj.login(mail_user, mail_pass)  # 登录验证
    smtpObj.sendmail(sender, receivers, message.as_string())  # 发送
    print("mail has been send to {0} successfully.".format(receivers))
except smtplib.SMTPException as e:
    print(e)

二、加强版附件传输邮件

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

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

# Files' Paths:
file1 = 'mail.py'
file2 = 'maill.py'
# 收邮件的地址，可以多个。
Receivers = ['receiver1@163.com'，'receiver2@163.com']
# 邮件主题：
title = 'Python SMTP 邮件(文件传输)'

# 模拟服务器
# SMTP服务器
SMTPServer="smtp.163.com"
# 发邮件的地址
Sender="yourname@163.com"
# 发送者邮件的授权密码，去163邮箱设置里获取。并非是密码。
passwd="xxx"  

# 创建一个带附件的实例
message = MIMEMultipart()
message['From'] = Sender
message['To'] = ",".join(Receivers)
message['Subject'] = title
# 邮件正文内容
message.attach(MIMEText('附件中是要传输的文件。\n ', 'plain', 'utf-8'))
message.attach(MIMEText('The files you need are as followed. \n ', 'plain', 'utf-8'))

# 构造附件1
att1 = MIMEText(open(file1, 'rb').read(), 'base64', 'utf-8')
att1["Content-Type"] = 'application/octet-stream'
att1["Content-Disposition"] = 'attachment; filename={0}'.format(file1)
message.attach(att1)

# 构造附件2
att2 = MIMEText(open(file2, 'rb').read(), 'base64', 'utf-8')
att2["Content-Type"] = 'application/octet-stream'
att2["Content-Disposition"] = 'attachment; filename={0}'.format(file2)
message.attach(att2)

try:
    mailServer = smtplib.SMTP(SMTPServer, 25)  # 25为端口号(邮件），0-1024都被系统占用了
    # 登录邮箱
    mailServer.login(Sender, passwd)  # 需要的是，邮箱的地址和授权密码
    # 发送文件
    mailServer.sendmail(Sender, Receivers, message.as_string())
    print("邮件发送成功")
    print("Mail with {0} & {1} has been send to {2} successfully.".format(file1,file2,Receivers))
except smtplib.SMTPException as e:
    print("Error: 无法发送邮件")
    print(e)

后话

可以把代码加到网络train.py的最后，别忘了在train.py的开头加上：

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

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

然后你就可以专心忙自己的事情，网络训练结束就自动发邮件啦~

果然——Codes change the world.
