存储日志记录信息为变量的电子邮件警报使用

Question

我只有几个星期的学习蟒蛇以前没有编程背景，所以我为我的无知道歉..

我试图用一个组合的模块来监视文件夹中的新文件（看门狗），任何事件（记录模块）上的警报，然后将警报发送到我的电子邮件（smtplib）。

我找到一个很好的例子在这里：How to run an function when anything changes in a dir with Python Watchdog?

但是，我坚持试图将日志记录信息保存为一个变量在我的电子邮件中使用。我想知道是否需要将日志记录信息输出到文件，然后在行中读取以用作变量。

反正，这就是我所拥有的。任何帮助表示赞赏。与此同时，我会继续Google。

import sys 
import time 
import logging 
from watchdog.observers import Observer 
from watchdog.events import LoggingEventHandler 
import smtplib 

class Event(LoggingEventHandler): 
    def on_any_event(self, event): 
     logMsg = logging.basicConfig(level=logging.INFO, 
         format='%(asctime)s - %(message)s', 
         datefmt='%Y-%m-%d %H:%M:%S') 

     sender = 'NoReply@myDomain.com' 
     receiver = 'test.user@myDomain.com' 
     message = """From: No Reply <NoReply@myDomain.com> 
     TO: Test User <test.user@myDomain.com> 
     Subject: Folder Modify Detected 

     The following change was detected: """ + str(logMsg) 

     mail = smtplib.SMTP('mailServer.myDomain.com', 25) 
     mail.ehlo() 
     mail.starttls() 
     mail.sendmail(sender, receiver, message) 
     mail.close() 

if __name__ == "__main__": 

    path = sys.argv[1] if len(sys.argv) > 1 else '.' 
    event_handler = Event() 
    observer = Observer() 
    observer.schedule(event_handler, path, recursive=False) 
    observer.start() 
    try: 
     while True: 
      time.sleep(1) 
    except KeyboardInterrupt: 
     observer.stop() 
    observer.join()

你需要的是一个SMTPHandler，这样每次该文件夹的变化（新日志中创建），电子邮件被发送。

import logging 
from watchdog.observers import Observer 
from watchdog.events import LoggingEventHandler 

class Event(LoggingEventHandler): 
    def on_any_event(self, event): 
     # do stuff 
     pass 

if __name__ == "__main__": 
    root = logging.getLogger() 
    root.setLevel(logging.INFO) 
    formatter = logging.Formatter('%(asctime)s - %(message)s', 
            '%Y-%m-%d %H:%M:%S') 
    root.setFormatter(formatter) 

    mail_handler = logging.handlers.SMTPHandler(mailhost='mailserver', 
               fromaddr='noreply@example.com', 
               toaddrs=['me@example.com'], 
               subject='The log', 
               credentials=('user','pwd'), 
               secure=None) 
    mail_handler.setLevel(logging.INFO) 
    mail_handler.setFormatter(formatter) 
    root.addHandler(mail_handler) # Add this handler to root logger 

    path = sys.argv[1] if len(sys.argv) > 1 else '.' 
    event_handler = Event() 
    observer = Observer() 
    observer.schedule(event_handler, path, recursive=False) 
    observer.start() 
    try: 
     while True: 
      time.sleep(1) 
    except KeyboardInterrupt: 
     observer.stop() 
    observer.join()
