使用了smtplib等第三方庫,進行傳送郵件,完成郵件報警功能

如下是例項 :

#!/usr/bin/python
 
import glob
import operator
from optparse import OptionParser
import smtplib
import email.MIMEText as MIMEText
import email.Utils.formadate as formatdate
 
msg = ""
#主方法
def main():
  global options
  global msg
 
  parser = OptionParser(add_help_option=False)
  parser.add_option("-m","--mail",dest="mail",type="str",help="email address to send report result (comma separated)")
  parser.add_option("-t","--title",dest="title",help="email title (default:Error File Count)")
  parser.add_option("-a","--admin",dest="admin",help="set sender address. works with -m option")
  (options,args) = parser.parse_args()
 
  #這裡監控資料夾下的檔案數,超出25個檔案即報警
  datanum = cntFiles("/data/","csv")
  if (operator.gt(datanum,25)):
    msg += " Please be alert : \n the number of files under /data/ path is greater than 25 :"
    msg += "\n =========================================="
    msg += "\n The number of files is : " + str(datanum)
    sendmsg(options,msg)
  print("==== end ====")
 
#添加發送郵件的資訊
def sendmsg(options,msg):
  if options.mail:
    toAddr = options.mail
    if options.admin:
      fromAddr = options.admin
    else:
      fromAddr = '[email protected]'#這裡是公司的公用SMTP郵箱賬號
 
    if options.title:
      subject = options.title
    else:
      subject = 'File Stacking Alarm'
    msg += "\n ========================================== \n"
    print( msg)
    msg = createMsg(fromAddr,toAddr,subject,msg)
    print( msg)
    send(fromAddr,msg)
  else:
    print( msg)
 
#glob方法,統計資料夾下的檔案數
def cntFiles(in_directory,ext):
  stage = len(glob.glob1(in_directory,"*." + ext))
  return stage
 
#建立郵件頭
def createMsg(fromAddr,body):
  msg = MIMEText(body)
  msg['Subject'] = subject
  msg['To'] = toAddr
  msg['From'] = fromAddr
  msg['Date'] = formatdate()
  return msg
 
#傳送郵件
def send(fromAddr,msg):
  try:
    #這裡新增公司的SMTP郵箱地址
     s = smtplib.SMTP('192.168.12.120')
     s.sendmail(fromAddr,toAddr.split(','),msg.as_string())
     s.close()
     print("SUCCESS: sending email")
  except smtplib.SMTPException:
     print("ERROR: sending email")
 
if __name__ == '__main__':
  main()

linux上做計劃任務,把指令新增進計劃任務中:

Errymsfileemail.py -m [email protected] -t "[ERROR/$HOST] File Stacking Alarm"
