Question

該腳本中缺少附件

我正在嘗試使用python腳本發送附件，但是我沒有收到附件，附件丟失了，讓我知道如何獲取現在丟失的附件以及此代碼中的錯誤是什么

import smtplib
import base64

filename = "D:\python/Files_List.txt"

fo = open("Files_List.txt", "rb")
filecontent = fo.read()
encodedcontent = base64.b64encode(filecontent)  # base64

sender = 'rom@domain.com'
reciever = 'to@domain.com'

marker = "AUNIQUEMARKe"

body ="""
This is a Attachment Mail
"""
part1 = """From:from<from@domain.com>
To:to<to@domain.com>
Subject: Sending Attachement
MIME-Version: 1.0
Content-Type: multipart/mixed; boundary=%s
--%s
""" % (marker, marker)

part2 = """Content-Type: text/plain
Content-Transfer-Encoding:8bit

%s
--%s
""" % (body,marker)

part3 = """Content-Type: multipart/mixed; name=\"%s\"
Content-Transfer-Encoding:base64
Content-Disposition: attachment; filename=%s

%s--%s--
""" %(filename, filename, encodedcontent, marker)
message = part1 + part2 + part3

try:
   smtpObj = smtplib.SMTP('localhost')
   smtpObj.sendmail(sender, reciever, message)
   print "Successfully sent email"
except Exception:
   print "Error: unable to send email"

您正在讀取要以二進制模式附加的文件，以便您的encodedcontent為bytes類型（可以）。 然后，將其格式化而不轉換為字符串。 結果，您的message包含b'....' （不正確）。
