Python-可以在平原项目中使用附件中的邮件，但不能在课堂上使用

Question

我正在从Windows文件夹中挑选一个文件，我正在尝试通过Gmail发送。
该代码在单独的Python程序中执行时可以正常工作，但是我无法在类中使用相同的程序。

import smtplib
import base64
filename = str("JDI Offline.txt").split('\')[-1:][0]
filepath = "C:WindowsJDI Offline.txt"
fo = open(filepath, "rb")
filecontent = fo.read()
fo.close()
encodedcontent = base64.b64encode(filecontent)
sender = '[e-mail]'
receiver = '[e-mail]'
marker = "AUNIQUEMARKER"
body = """
Test to send attatchment
"""
part1 = """From: From Varshil<[e-mail]>
To:me
Subject: Sending attatchment
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: attatchment; filepath=%s
%s
--%s--
""" % (filename, filepath, encodedcontent, marker)
message = part1 + part2 + part3
try:
    mail = smtplib.SMTP('smtp.gmail.com', 587)
    mail.ehlo()
    mail.starttls()
    mail.login('[e-mail]', 'xxxxxxxx')
    mail.sendmail('[e-mail]', '[e-mail]', message)
    print "Mail Sent successfully"
except Exception:
    print "Error"

当我在类中使用此代码时，我会收到空白邮件。我已连接屏幕截图

在类中使用程序的程序
程序的程序时，没有类的程序

类Sendmail： def send_mail（）： 导入SMTPLIB 导入base64

filename = str("JDI Offline.txt").split('\')[-1:][0]
filepath = "C:WindowsJDI Offline.txt"
fo = open(filepath, "rb")
filecontent = fo.read()
fo.close()
encodedcontent = base64.b64encode(filecontent)
sender = '[e-mail]'
receiver = '[e-mail]'
marker = "AUNIQUEMARKER"
body = """
Test to send attatchment
"""
part1 = """From: From Varshil<[e-mail]>

message = part1 + part2 + part3
try:
    mail = smtplib.SMTP('smtp.gmail.com', 587)
    mail.ehlo()
    mail.starttls()
    mail.login('[e-mail]', 'xxxxxxxx')
    mail.sendmail('[e-mail]', '[e-mail]', message)
    print "Mail Sent successfully"
except Exception:
    print "Error"
ob=sendmail()
ob.send_email()

有人请告诉什么问题。

我找到了解决问题的解决方案。该代码没有工作，因此我搜索了一个新代码。我正在此处发布代码以备将来参考。在以下代码中，我正在读取文件中的数据并附加标签，因为这是我的要求。您可以根据需要更改代码

# coding:utf-8

    part = MIMEBase.MIMEBase('application', 'octet-stream')
    part.set_payload((filecontent))
    encoders.encode_base64(part)
    part.add_header('Content-Disposition', "attachment; filename= %s" % filename)
    msg.attach(part)
