Python3如何使用SMTP發(fā)送帶附件郵件？

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 = '主題：這是帶附件的郵件' 
 
# 創(chuàng)建一個(gè)帶附件的實(shí)例 
message = MIMEMultipart() 
message['From'] = sender 
message['To'] = receiver 
message['Subject'] = Header(mail_title, 'utf-8') 
 
# 郵件正文內(nèi)容 
message.attach(MIMEText('來(lái)來(lái)來(lái)，這是郵件的正文', 'plain', 'utf-8')) 
 
# 構(gòu)造附件1（附件為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) 
 
# 構(gòu)造附件2（附件為JPG格式的圖片） 
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) 
 
# 構(gòu)造附件3（附件為HTML格式的網(wǎng)頁(yè)） 
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：如果遇到發(fā)送失敗的情況（提示遠(yuǎn)程主機(jī)拒接連接），這里要使用SMTP_SSL方法 
smtpObj.connect(smtpserver) 
smtpObj.login(username, password) 
smtpObj.sendmail(sender, receiver, message.as_string()) 
print("郵件發(fā)送成功！??！") 
smtpObj.quit()
