Python 当我将名称设置为变量时，作为 xlsx 的电子邮件附件不起作用

Question

我想不时发送自动邮件至，并在邮件中附加一个 excel 文件。如果我直接在前面写 excel 文件的名称就可以了，但是如果我 link 它到一个变量，会发生什么是附加的无格式文件。e-mail view at inbox

简而言之，我希望这一行与一个名为 attachmentFile 的变量一起使用，而不是编写“2020-01-01.xlsx” part.add_header('Content-Disposition', 'attachment; filename="attachmentFile"')

import smtplib,ssl
from email.mime.multipart import MIMEMultipart
from email.mime.base import MIMEBase
from email.mime.text import MIMEText
from email.utils import formatdate
from email import encoders

attachmentFile="2021-01-02.xlsx"
def send_mail():

  send_from= 'spotalert@****.com'
  send_to='deniz.yildirim@****.com'
  subject = 'Uygunsuz Punta Bildirimi'

  body_1='Merhaba\n'
  body_2= 'xxxxx Nolu Punta Tahribatli kontrolde uygunsuz cikmistir.\n'
  body_3='Uygunsuzluk sebebi =  xxxxxxx '      + 'Puntanin Bulundugu Posta :'+'\n'
  body_4= ' Bu otomatik bir maildir lutfen cevap vermeyiniz.\n'
  body_5='Uygunsuzlugun ciktigi tarih'+ '\n'


  text = body_1 + body_2 + body_3 + body_4 +body_5 
  msg = MIMEMultipart()
  msg['From'] = send_from
  msg['To'] = send_to
  msg['Date'] = formatdate(localtime = True)
  msg['Subject'] = subject
  msg.attach(MIMEText(text))

  part = MIMEBase('application', "octet-stream") 
  part.set_payload(open(attachmentFile, "rb").read())
  encoders.encode_base64(part)
  part.add_header('Content-Disposition', 'attachment; filename="2021-01-02.xlsx"')
  msg.attach(part)

Answer 1

在代码的倒数第二行，而不是：

part.add_header('Content-Disposition', 'attachment; filename="2021-01-02.xlsx"')

使用这个：

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