使用SMTP发送xlsx文件&；Python 3

我在将文件名附加到电子邮件并发送时，无法让SMTP服务器保留我的文件名。我运行了两次，效果非常好。姓名和excel表按预期显示。现在，无论我做什么，附件总是像ATT00001.xlsx一样，过去它工作得很好。（确切地说是在午餐休息时离开，回来后重新运行，没有任何更改）我想知道是否是我如何将excel表附加到我的电子邮件中的。有人知道这是怎么回事吗？谢谢

msg = MIMEMultipart()
sender='email@email.org'
recipients='email@recipient.org'
server=smtplib.SMTP('mail.server.lan')

msg['Subject']='Quarterly Summary'
msg['From']=sender
msg['To']=recipients



filename = r'C:\Users\user.chad\Quarterly\project\output\MyData.xlsx'
attachment = open(r'C:\Users\user.chad\Quarterly\project\output\MyData.xlsx', 'rb')
xlsx = MIMEBase('application','vnd.openxmlformats-officedocument.spreadsheetml.sheet')
xlsx.set_payload(attachment.read())

encoders.encode_base64(xlsx)
xlsx.add_header('Content-Dispolsition', 'attachment', filename=filename)
msg.attach(xlsx)

server.sendmail(sender, recipients, msg.as_string())
server.quit()
attachment.close()

请记录在案：

xlsx.add_header('Content-Dispolsition', 'attachment', filename=filename)

应该是

xlsx.add_header('Content-Disposition', 'attachment', filename=filename)

这是添加带有text/html内容的附件的示例

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.mime.base import MIMEBase
from email import encoders

message = MIMEMultipart()

# add text
message.attach(
    MIMEText(
        content,
        'html',
        'utf-8'
        )
    )

# add attachment
attachment = MIMEBase('application', "octet-stream")
# open a file to attach
attachment.set_payload(open(filepath, "rb").read())
encoders.encode_base64(attachment)
attachment.add_header('Content-Disposition', 'attachment; filename="%s"' % self.filename )
message.attach(attachment)


server.sendmail(SENDER, receivers, message.as_string())

你确定这是内容分发吗？我有这样的东西：用open（attachment，“rb”）作为attache:part=MIMEApplication（attach.read（），Name=os.path.basename（attachment））part['Content-Disposition']='attachment；filename=“{}”格式（os.path.basename（附件））msg.attach（part）@E.Serra duuude。拼写错误。非常感谢。如果你把这个作为一个答案，我会相信你。没问题，伙计，很乐意帮忙
