利用Python发送邮件

xiaoxiaoniaoer 2019-12-07

Python对SMTP支持有smtplibemail两个模块,email负责构造邮件,smtplib负责发送邮件。

首先要对邮箱进行设置,这里以QQ邮箱为例:

打开QQ邮箱后,选择“设置-账户”,找到“POP3/IMAP/SMTP/Exchange/CardDAV/CalDAV服务”

利用Python发送邮件

开启pop3/smtp服务,并保存该授权码作为密码使用--生成授权码

 利用Python发送邮件

 最后代码如下:

# -*- coding:utf-8 -*-
import smtplib
from email.mime.text import MIMEText
from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart

class send_email():
    def __init__(self):
        self.Host = "smtp.qq.com"                # QQ邮箱服务地址
        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(多个用逗号隔开)

    # ==========================发送文本====================
    # 发送邮件主体到对方的邮箱中
    def email_text(self,message):
        message_text = MIMEText(_text=‘<h2 style="color:red;font-size:100px"><a href="http://www.baidu.com">这是一个链接</a></h2>‘,_subtype=‘html‘, _charset=‘utf-8‘)
        message.attach(message_text)


    # ==========================发送图片====================
    def email_image(self,message):
        image_data = open(file="123456789.jpg", mode="rb")
        message_image = MIMEImage(_imagedata=image_data.read(), _subtype="base64", _charset="utf-8")

        # 设置文件在附件当中的名字
        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=r"C:\Users\lenovo\Desktop\income.xlsx", mode="rb")
        message_file = MIMEText(_text=file_data.read(), _subtype="base64", _charset="utf-8")

        # 设置文件在附件当中的名字
        message_file[‘Content-Disposition‘] = ‘attachment;filename="textfile.xlsx"‘
        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为邮箱授权码
        result = email_client.login(user=self.From, password="eejjgbvxpzyadhhg")
        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()
    email = send_email()            # 调用对象

    # email.email_text(message)       # 调用对象的方法
    email.email_image(message)
    # email.email_file(message)

    email.init_email()
