在python中发送每个txt文件的附件电子邮件

Question

我有多个文件预定义路径的一部分，我试图为每个可用的txt文件生成一个电子邮件。 下面的代码仅适用于一次，但每个文件每个电子邮件增加一个。

您的输入/建议将非常有帮助。 感谢， AL

    shutil.move(iFiles, destinationFolder) 
    msg.attach(part) 
    #shutil.move(iFiles, destinationFolder) 
    #Mail trigger module 
    server = smtplib.SMTP('IP:25') 
    server.sendmail('[email protected]',['[email protected]'], msg.as_string()) 
    server.quit() 
    print "Email successfully sent!" 
    print "Files moved successfully" 

print "done"

这个问题就出现在这里：

msg.attach(part) 

你在做什么是附加部分此起彼伏，没有清理以前附加部分。

您应该丢弃以前连接的零件，或重新初始化msg。在实践中，重新初始化msg更容易。

# ... code before 

msg=email.mime.Multipart.MIMEMultipart() 
#msg['Subject'] = ' 
msg['From'] = '[email protected]' 
msg['To'] = '[email protected]' 

part = MIMEApplication(open(iFiles).read()) 
part.add_header('Content-Disposition', 
       'attachment; filename="%s"' % os.path.basename(iFiles)) 
shutil.move(iFiles, destinationFolder) 

# ... code after
