为python中的每个txt文件发送附件电子邮件

Question

我在预定义路径中包含多个文件，并且正在尝试为每个可用的txt文件生成电子邮件。 下面的代码只能工作一次，但是每封电子邮件的每个文件都会递增。

您的意见/建议将非常有帮助。 谢谢AL

print "done"

此问题出现在这里：

msg.attach(part)

您正在做的是一个接一个地连接零件，而不清洗以前连接的零件。

您应该丢弃先前连接的部件，或重新初始化msg 。 实际上，重新初始化msg更容易。

# ... code before

msg=email.mime.Multipart.MIMEMultipart()
#msg['Subject'] = '
msg['From'] = 'john@domain.com'
msg['To'] = 'user1@domain.com'

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

# ... code after
