python - 使用 Tweepy 给自己发送电子邮件提醒。但是电子邮件内容正在累积每条推文。我想让它覆盖

Question

我正在使用 Tweepy 和流媒体实时跟踪推文。每当有人用某些关键词发帖时，我都会尝试通过电子邮件将推文发送给自己:

class StreamCollector(tweepy.Stream):

    def on_status(self, status):
        if not hasattr(status, 'retweeted_status') and status.in_reply_to_screen_name == None and status.is_quote_status == Fal\
se:
            if status.author.followers_count > 10:
                print('Twitter Handle: @'+status.author.screen_name)
                print('Followers:',status.author.followers_count)
                print('Tweet:',status.text)
                print('\n')

                mail_content = 'Tweet: {0}\nFollowers: {1}\nTweet Link: https://twitter.com/{2}/status/{3}'.format(status.text,\
status.author.followers_count,status.author.screen_name,status.id_str)

                message['Subject'] = '@'+status.author.screen_name   #The subject line                                          


                message.attach(MIMEText(mail_content, 'plain')) #Create SMTP session for sending the mail                       
                session = smtplib.SMTP('smtp.gmail.com', 587) #use gmail with port                                              
                session.starttls() #enable security                                                                             
                session.login(sender_address, sender_pass) #login with mail_id and password                                     

                text = message.as_string()
                session.sendmail(sender_address, receiver_address, text)
                mail_content = []
                session.quit()

stream = StreamCollector(api_key,api_key_secret,access_token, access_token_secret)
stream.filter(track=["trigger words"])

一切正常 - 除了 - mail_content 似乎附加在每条新推文中 - 但我希望它被覆盖。目前，每封新电子邮件还包含所有先前推文的 mail_content。

谁能解释为什么会这样，我该如何解决？

看起来 message 被重用了，你继续做 attach(payload) .

调用set_content()相反。

# message.attach(MIMEText(mail_content, 'plain'))  # -
message.set_content(mail_content)                  # +

您可能也应该每次都创建一个新的 message 实例。
