利用Python脚本实现发送邮件

python发送邮件，以QQ邮箱为例

import smtplib
from email.mime.text import MIMEText
from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart
# smtplib模块负责连接服务器和发送邮件
# MIMEText：定义邮件的文字数据
# MIMEImage：定义邮件的图片数据
# MIMEMultipart：负责将文字图片音频组装子一起添加附件
class Send_email():
    def __init__(self):
        self.Host = "smtp.qq.com"     #qq邮箱的服务地址
        self.Subject = input("请输入邮件标题：") #设置邮件标题
        self.From = input("请输入发件人地址：") #设置发件人邮箱
        self.To = input("请输入收件人地址：")  #设置收件人邮箱

    # ==========================发送文本====================
    def email_text(self,message ):
        message_text = MIMEText(_text='<h2 style = "color:red;font-size:100px"><a href="http://www.baidu.com">这是网址</h2>')
        message.attach(message_text)

    # ==========================发送图片====================
    def email_image(self,message):
        image_data = open(file="D:\下载\2032946.jpg",mode="rb")
        message_image = MIMEImage(_imagedata=image_data.read(),_subtype="base64",_charset ="utf-8")

        # 设置发送邮件图片的名字
        message_image["Content-disposition"] = 'attachment;filename = "text.jpg"'
        image_data.close()
        message.attach(message_image)

    # ==========================发送附件====================
    def email_file(self,message):
        file_data = open(file="C:\Users\37461\Desktop\新建 XLS 工作表.xls",mode="rb")
        message_file = MIMEText(_text=file_data.read(),_subtype="base64",_charset="utf-8")

        # 设置发送邮件附件的名字
        message_file["Content-Disposition"] = 'attachment;filename = "textfile.xls"'
        file_data.close()
        message.attach(message_file)

    # ==========================发送邮件====================
    def init_email(self):
        message["From"]= self.From          #设置邮件发件人
        message["To"] = self.To             #设置邮件接收人
        message["Subject"] = self.Subject   #设置邮件标题

        # 获取简单邮件传输协议证书
        email_client = smtplib.SMTP_SSL(host="smtp.qq.com")
        # 设置发件人邮箱的域名和端口
        email_client.connect(host="smtp.qq.com",port="465")

        # 登陆邮件，权限验证，password为邮箱密码
        result = email_client.login(user=self.From,password="ohuwivaostufbhei")
        print("登录结果",result)

        # 发送邮件，from_addr：发送人，to_addrs：收件人 ，msg：发送的文本
        email_client.sendmail(from_addr=self.From,to_addrs=self.To,msg=message.as_string())
        # 关闭邮件客户端
        email_client.close()

if __name__== "__main__":
    # 创建一个邮件对象
    message = MIMEMultipart()
    # 调用
    email = Send_email()
    email.email_text(message)
    email.email_image(message)
    email.email_file(message)
    email.init_email()
