Python3使用SMTP发送带附件邮件

import smtplib 
from email.header import Header 
from email.mime.text import MIMEText 
from email.mime.multipart import MIMEMultipart 
 
sender = 'XXXXX@163.com' 
receiver = 'XXXXX@qq.com' 
smtpserver = 'smtp.163.com' 
username = 'XXXXX' 
password = 'XXXXX' 
mail_title = '主题：这是带附件的邮件' 
 
# 创建一个带附件的实例 
message = MIMEMultipart() 
message['From'] = sender 
message['To'] = receiver 
message['Subject'] = Header(mail_title, 'utf-8') 
 
# 邮件正文内容 
message.attach(MIMEText('来来来，这是邮件的正文', 'plain', 'utf-8')) 
 
# 构造附件1（附件为TXT格式的文本） 
att1 = MIMEText(open('text1.txt', 'rb').read(), 'base64', 'utf-8') 
att1["Content-Type"] = 'application/octet-stream' 
att1["Content-Disposition"] = 'attachment; filename="text1.txt"' 
message.attach(att1) 
 
# 构造附件2（附件为JPG格式的图片） 
att2 = MIMEText(open('123.jpg', 'rb').read(), 'base64', 'utf-8') 
att2["Content-Type"] = 'application/octet-stream' 
att2["Content-Disposition"] = 'attachment; filename="123.jpg"' 
message.attach(att2) 
 
# 构造附件3（附件为HTML格式的网页） 
att3 = MIMEText(open('report_test.html', 'rb').read(), 'base64', 'utf-8') 
att3["Content-Type"] = 'application/octet-stream' 
att3["Content-Disposition"] = 'attachment; filename="report_test.html"' 
message.attach(att3) 
 
 
smtpObj = smtplib.SMTP_SSL() # 注意：如果遇到发送失败的情况（提示远程主机拒接连接），这里要使用SMTP_SSL方法 
smtpObj.connect(smtpserver) 
smtpObj.login(username, password) 
smtpObj.sendmail(sender, receiver, message.as_string()) 
print("邮件发送成功！！！") 
smtpObj.quit()
