问题描述

我写了一个简单的脚本来通过Gmail SMTP服务器发送电子邮件.这里的代码:

I wrote a simple script to send an email via the Gmail SMTP server. Here the code:

import smtplib
msg = 'Hello World!'
server = smtplib.SMTP('smtp.gmail.com', 587) #port 465 or 587
server.ehlo()
server.starttls()
server.ehlo()
server.login('username@googlemail.com','password')
server.sendmail('username@googlemail.com','username@googlemail.com', msg)
server.close()

有时它可以工作,有时会出现错误.是什么原因呢?我已将Gmail配置为接受安全性较低的应用程序.如果发生错误,我会收到以下消息:

Sometimes it works and sometimes I get an error. What is the reason for it? I have configured Gmail for accepting less secure apps. If the error occurs I get the following message:

Traceback (most recent call last):
  File "email.py", line 31, in <module>
    server.login('username@googlemail.com','password')
  File "/usr/lib/python3.5/smtplib.py", line 729, in login

    raise SMTPAuthenticationError(code, resp)

推荐答案

答案建议首先为安全性较低的应用启用访问权限.如果那不起作用,您可以尝试访问该页面上提供的链接: https://www.google.com/accounts/DisplayUnlockCaptcha

The answer recommends enabling access for less secure apps first. If that does not work you could try visiting the link, which is supplied on that page: https://www.google.com/accounts/DisplayUnlockCaptcha

这可以启用访问权限.
