如何使用smtplib实现python自动邮件发送器？

Question

我正在尝试使用auto-mailer编写python smtplib。我已经在运行它，但是我一直在打我的except语句。

代码看起来像这样。

    sender = ['[email protected]']
    receivers = ['[email protected]']

    subject = "does this work?"
    message = "this is a cool email"

    try:
        server = smtplib.SMTP('smtp.gmail.com:587')
        server.ehlo()
        server.starttls()
        server.sendmail(sender, receivers, message)
        print("Successfully sent email")
        server.quit()
    except smtplib.SMTPException:
        print("Error: unable to send email")

感谢您的任何帮助。

编辑：堆栈跟踪如下

Traceback (most recent call last):

    email_protocol()
  File "C:/Users/....py", line 33, in email_protocol
    server.sendmail(sender, receivers, message)
  File "C:\Users\...\lib\smtplib.py", line 867, in sendmail
    raise SMTPSenderRefused(code, resp, from_addr)

该错误很容易解释。您需要提供身份验证。

server.login('<gmaiL-id>', '<password>')

将其放在server.starttls()之后
