如何使用Python以Gmail作为提供者发送电子邮件?

我试图使用python发送电子邮件(Gmail)，但我得到以下错误。

Traceback (most recent call last):  
File "emailSend.py", line 14, in <module>  
server.login(username,password)  
File "/usr/lib/python2.5/smtplib.py", line 554, in login  
raise SMTPException("SMTP AUTH extension not supported by server.")  
smtplib.SMTPException: SMTP AUTH extension not supported by server.

Python脚本如下所示。

import smtplib

fromaddr = 'user_me@gmail.com'
toaddrs  = 'user_you@gmail.com'
msg = 'Why,Oh why!'
username = 'user_me@gmail.com'
password = 'pwd'
server = smtplib.SMTP('smtp.gmail.com:587')
server.starttls()
server.login(username,password)
server.sendmail(fromaddr, toaddrs, msg)
server.quit()

这是

创建Gmail APP密码!

创建之后，创建一个名为sendgmail.py的文件

然后添加以下代码:

try:

    server.ehlo()
    server.login(gmail_user, gmail_app_password)
    server.sendmail(sent_from, sent_to, email_text)
    server.close()

    print('Email sent!')
except Exception as exception:
    print("Error: %s!\n\n" % exception)

所以，如果你成功了，你会看到这样的图像:

其他回答

来自@David的很棒的回答，这里是Python 3没有通用的try-除了:

def send_email(user, password, recipient, subject, body):

    gmail_user = user
    gmail_pwd = password
    FROM = user
    TO = recipient if type(recipient) is list else [recipient]
    SUBJECT = subject
    TEXT = body

    # Prepare actual message
    message = """From: %s\nTo: %s\nSubject: %s\n\n%s
    """ % (FROM, ", ".join(TO), SUBJECT, TEXT)

    server = smtplib.SMTP("smtp.gmail.com", 587)
    server.ehlo()
    server.starttls()
    server.login(gmail_user, gmail_pwd)
    server.sendmail(FROM, TO, message)
    server.close()

我遇到过类似的问题，并无意中发现了这个问题。我得到一个SMTP身份验证错误，但我的用户名/ pass是正确的。下面是解决问题的方法。我读到:

https://support.google.com/accounts/answer/6010255

简而言之，谷歌不允许您通过smtplib登录，因为它已经标记了这种登录为“不太安全”，所以你要做的是去这个链接，而你登录到你的谷歌帐户，并允许访问:

https://www.google.com/settings/security/lesssecureapps

一旦设置好了(见下面的截图)，它就可以工作了。

登录现在工作:

smtpserver = smtplib.SMTP("smtp.gmail.com", 587)
smtpserver.ehlo()
smtpserver.starttls()
smtpserver.ehlo()
smtpserver.login('me@gmail.com', 'me_pass')

更改后的回复:

(235, '2.7.0 Accepted')

响应之前:

smtplib.SMTPAuthenticationError: (535, '5.7.8 Username and Password not accepted. Learn more at\n5.7.8 http://support.google.com/mail/bin/answer.py?answer=14257 g66sm2224117qgf.37 - gsmtp')

还是不行?如果您仍然得到SMTPAuthenticationError，但现在代码是534，这是因为位置未知。点击这个链接:

https://accounts.google.com/DisplayUnlockCaptcha

点击继续，这应该给你10分钟的时间来注册你的新应用。所以现在继续进行另一次登录尝试，它应该可以工作。

更新:这似乎不能马上工作，你可能会卡在smptlib中得到这个错误:

235 == 'Authentication successful'
503 == 'Error: already authenticated'

该消息说使用浏览器登录:

SMTPAuthenticationError: (534, '5.7.9 Please log in with your web browser and then try again. Learn more at\n5.7.9 https://support.google.com/mail/bin/answer.py?answer=78754 qo11sm4014232igb.17 - gsmtp')

启用“lesssecureapps”后，去喝杯咖啡，回来后再次尝试“DisplayUnlockCaptcha”链接。从用户体验来看，更改可能需要一个小时才能生效。然后再次尝试登录过程。

你需要在直接运行到STARTTLS之前说EHLO:

server = smtplib.SMTP('smtp.gmail.com:587')
server.ehlo()
server.starttls()

此外，您应该真正创建From:、To:和Subject:消息头，用空行与消息体分隔，并使用CRLF作为EOL标记。

E.g.

msg = "\r\n".join([
  "From: user_me@gmail.com",
  "To: user_you@gmail.com",
  "Subject: Just a message",
  "",
  "Why, oh why"
  ])

注意:

为了做到这一点，你需要在gmail帐户配置中启用“允许不太安全的应用程序”选项。否则，当gmail检测到一个非谷歌应用程序试图登录你的帐户时，你会得到一个“关键安全警报”。
