通過Google App Engine中的smtp和Gmail發送電子郵件的身份驗證錯誤

Question

我試圖通過App Engine中的SMTP通過Google Apps電子郵件發送電子郵件，但在sendmail調用期間我收到了「需要授權」。看起來auth調用本身成功了。

這是我要發送的消息。這是通過IMAP檢索的草稿，所以我知道訪問令牌是好的。它是由Python的email.Message.as_string方法生成的。

foo bar 

--14dae94edfeda1125304f61e1fec 
Content-Type: text/html; charset=UTF-8 

<div dir="ltr">foo bar</div> 

--14dae94edfeda1125304f61e1fec-- 

這裏是我的代碼：

auth_string = 'user=%s^Aauth=Bearer %s^A^A' % ('john@mydomain.com', access_token) 
smtp = smtplib.SMTP('smtp.gmail.com', 587) 
smtp.set_debuglevel(True) 
smtp.ehlo() 
smtp.starttls() 
smtp.ehlo() 
smtp.docmd('AUTH', 'XOAUTH2 ' + base64.b64encode(auth_string)) 
smtp.sendmail('john@mydomain.com', ['ela@mydomain.com'], rfc822_msg_str) 

這裏從SMTP的調試消息。

Answer 1

您從電子郵件應該註冊Google App Engine應用程序。 Google對來自電子郵件ID的限制。這是工作代碼。

__author__ = 'Om Narayan' 
__revision__ = '$' 
__version__ = '0.1' 
__maintainer__ = 'Om Narayan' 
__email__ = 'om.narayan29@gmail.com' 
__status__ = 'Prototype' 

import json 
from app.baseRequestHandler import * 
from google.appengine.api import mail 
from webapp2_extras import auth, sessions, jinja2 


class Email(BaseRequestHandler): 
    def send(self, values, templateFile): 
    message = mail.EmailMessage(sender="<Sender Name> <sender email id registered with google app engine>", 
          subject=values['subject']) 
    message.to = "%s <%s>" % (values['userName'], values['userEmail']) 
    message.body = self.jinja2.render_template('/email/%s.txt' % templateFile, **values) 
    message.html = self.jinja2.render_template('/email/%s.html' % templateFile, **values) 
    message.send() 

    def sendMulti(self, values, templateFile): 
    message = mail.EmailMessage(
       sender="%s (<Sender Name>) <sender email id registered with google app engine>" % values["authorName"], 
       subject=values['subject']) 
    message.to = "%s" % (values['recipients']) 
    message.body = self.jinja2.render_template('/email/%s.txt' % templateFile, **values) 
    message.html = self.jinja2.render_template('/email/%s.html' % templateFile, **values) 
    message.send()
