Python对SMTP支持有smtplib和email两个模块，email负责构造邮件，smtplib负责发送邮件。
Python对SMTP支持有smtplib和email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”
开启pop3/smtp服务，并保存该授权码作为密码使用--生成授权码
最后代码如下：
# -*- coding:utf-8 -*-import smtplibfrom email.mime.text import MIMETextfrom email.mime.image import MIMEImagefrom email.mime.multipart import MIMEMultipartclass 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 ><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()
