python 发邮件

python发送邮件并带有附件，如果安装相关的包，先用pip安装这些包：smtplib，email

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.application import MIMEApplication
 
 
 # msg，邮件的正文
 def send_mail(msg):
     # 设置邮件服务器，请按实际情况修改
     mail_host = "smtp.xxx.com.cn"
     # 登录邮件的帐号，请按实际情况修改
     mail_user = "test"
     # 登录邮件的密码，请按实际情况修改
     mail_pass = "test123456"
     # 发送人，请按实际情况修改
     sender = 'test@xxx.com.cn'
     # 接收人,，请按实际情况修改，多个接收人以逗号隔开
     receivers = ['test1@xxx.com.cn', 'test2@xxx.com.cn']
     # msg = MIMEMultipart('mixed')
     msg = MIMEMultipart('related')
     # 邮件标题，请按实际修改
     msg['Subject'] = u"这里是邮件的标题 "
     msg['From'] = sender
     # 收件人为多个收件人,通过join将列表转换为以;为间隔的字符串
     msg['To'] = ";".join(receivers)
 
     # 设置邮件正文
     html_msg = msg
     text_plain = MIMEText(html_msg, 'html', 'utf-8')
     msg.attach(text_plain)
 
     # 设置附件,file_path是附件的路径，请按实际情况修改
     file_path = "d:test.html"
     sendfile = MIMEApplication(open(file_path, 'rb').read())
     sendfile.add_header('Content-Disposition', 'attachment', filename='fail-report.html')
     msg.attach(sendfile)
 
     try:
         smtpObj = smtplib.SMTP()
         smtpObj.connect(mail_host)
         smtpObj.login(mail_user, mail_pass)
         smtpObj.sendmail(sender, receivers, msg.as_string())
         print ("邮件发送成功")
     except smtplib.SMTPException:
         print ("邮件发送失败")
