利用python自动发邮件

工作中有时长时间运行代码时需要监控进度，或者需要定期发送固定格式邮件时，可以使用下面定义的邮件函数。

该函数调用了outlook和qqmail的接口，只需要放置到python的环境目录中即可 import 并使用。这里建议所有自己定义的函数放置在python3的文件下 而非site-package文件下。

也可以防止在任意默认环境路径下。默认路径查询:

import site;
site.getsitepackages()

自己定义的函数将py文件命名为send_mail.py然后放置在上面显示的其中一个路径下即可。

代码:

def send_outlook(title,body,receivers,attachments):
    '''
    ==========================================================

    title='this is a title!'
    body=
    '
        Mates!
        Bon Apetite
    '
    receivers=['123211855@qq.com','ext.wenzhe.tian@uaes.com']
    attachments=['a.py','b.py'];

    send_outlook(title,body,receivers,attachments)

    ==========================================================
    '''
    import win32com.client as win32
    import warnings
    import pythoncom
    warnings.filterwarnings('ignore')
    pythoncom.CoInitialize()
    sub=title;
    body = body
    outlook = win32.Dispatch('outlook.application')
    receivers = receivers
    for i in receivers:
        mail = outlook.CreateItem(0)
        mail.To = i
        mail.Subject = sub
        mail.Body = body
        for j in attachments:
            mail.Attachments.Add(j)
        mail.Send()

def send_qqmail(user,password,title,body,image,receivers,attachments):
    '''
    ==========================================================

    user='123211855@qq.com';
    password='zpkfkgxvdrnvbgcj'
    title='this is a title!'
    body=
    '
        Mates!
        Bon Apetite
    '
    receivers=['123211855@qq.com','ext.wenzhe.tian@uaes.com']
    attachments=[];

    send_qqmail(user,password,title,body,image,receivers,attachments)

    ==========================================================
    '''
    import smtplib
    from email.mime.text import MIMEText
    from email.mime.image import MIMEImage
    from email.mime.multipart import MIMEMultipart
    # 设置邮箱的域名
    HOST = 'smtp.qq.com'

    message = MIMEMultipart('related')

    #--------------------------------------发送文本-----------------

#    message_html = MIMEText('<h2 style="color:red;font-size:100px">CSDN博客超级好</h2><img src="cid:big">','html','utf-8')
    message_text=MIMEText(body,'plain','utf-8')
    message.attach(message_text)

    #-------------------------------------发送图片--------------------
    # rb  读取二进制文件
    # 要确定当前目录有1.jpg这个文件
    for i in image:
        image_data = open(i,'rb')
        # 设置读取获取的二进制数据
        message_image = MIMEImage(image_data.read())

        image_data.close()
        message_image.add_header('Content-ID','big')
        # 添加图片文件到邮件信息当中去
        message.attach(message_image)

    #-------------------------------------添加文件---------------------

#    message_xlsx = MIMEText(open(r'C:\Users\ext.wenzhe.tian\Desktop\Dynamic_Data_Analysis_v3\Static_data_read_v2.py','rb').read(),'base64','utf-8')
    for i in attachments:
        message_xlsx = MIMEText(open(i,'rb').read(),'base64','utf-8')
        # 设置文件在附件当中的名字
        message_xlsx['Content-Disposition'] = 'attachment;filename='+i
        message.attach(message_xlsx)

    # 设置邮件发件人
    message['From'] = FROM
    # 设置邮件收件人
    message['To'] = TO
    # 设置邮件标题
    message['Subject'] = SUBJECT

    # 获取简单邮件传输协议的证书
    email_client = smtplib.SMTP_SSL()
    # 设置发件人邮箱的域名和端口，端口为465
    email_client.connect(HOST,'')
    # ---------------------------邮箱授权码------------------------------
    result = email_client.login(FROM,password)
    print('登录结果',result)
    email_client.sendmail(from_addr=FROM,to_addrs=TO.split(','),msg=message.as_string())
    # 关闭邮件发送客户端
    email_client.close()

以上代码分outlook邮件和qq邮件发送，qq邮箱发送需开启smtp的服务。

调用方法如下:

from send_mail import send_outlook
from send_mail import send_qqmail
help(send_outlook)
help(send_qqmail)

        Mates!
        Bon Apetite
    '
    receivers=['xxx@qq.com','xxx@xx.com']
    attachments=['a.py','b.py'];

    send_outlook(title,body,receivers,attachments)

    ====================================================================

    ==========================================================

    user='xxxxx@qq.com';
    password='xxxxx'
    title='this is a title!'

    '
    receivers=['xx@qq.com','xx@xx.com']
    attachments=[];

    send_qqmail(user,password,title,body,image,receivers,attachments)
