python - 通过smtplib错误在本地发送电子邮件

Question

I'm trying to send an email using smtplib without storing smtp credentials locally. I found this article https://www.tutorialspoint.com/python/python_sending_email.htm but get an error. I've fairly new with smtplib. Any help would be appreciated.

#!/usr/bin/python

import smtplib

message = """From: From Person <from@fromdomain.com>
To: To Person <to@todomain.com>
MIME-Version: 1.0
Content-type: text/html
Subject: SMTP HTML e-mail test

This is an e-mail message to be sent in HTML format

<b>This is HTML message.</b>
<h1>This is headline.</h1>
"""

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

error

NameError: name 'SMTPException' is not defined

Answer 1

SMTPException is in the module smtplib. So you either need to import that name, or use smtplib.SMTPException

Answer 2

你应该做那个 smtplib.SMTPException 或者做这行代码从 smtplib import SMTPException 导入它
