本文实例为大家分享了python监控文件并发送邮件的具体代码，供大家参考，具体内容如下

一、配置文件

import time,datetime 
 
TODAY = time.time() 
TIME_PATH = str(TODAY.year) + "/" + str(TODAY.month) + "/" + str(datetime.datetime.now().date()) 
 
MONITOR_CONFIG = { 
 "monitor_file":[ 
  {"key":"py_distribute-datacollect","path":"/home/vagrant/py_distribute/data/" + TIME_PATH + "_error.txt","max_size":100}, 
 ], 
 "send_account":"xxxx@qq.com", 
 "license_code":"feruwfpsiwkuibge", # 授权码 
 "rec_account":["xxxx@qq.com"], 
 "host":"smtp.qq.com", 
 "port":465, 
 "sleep_time":60, 
}

二、监控

import smtplib 
import logging 
import time 
import os 
from email.mime.text import MIMEText 
from monitor_config import MONITOR_CONFIG 
 
FORMAT = '[%(asctime)-15s] %(message)s' 
logging.basicConfig(filename = "monitor.txt", level = logging.DEBUG, filemode = "a", format=FORMAT) 
 
def get_file_size(file_name): 
 if os.path.exists(file_name): 
  bytes_size = float(os.path.getsize(file_name)) 
  kb = bytes_size/1024 
  mb = kb/1024 
  return mb 
 return 0 
 
def send_email(file_name,key): 
 msg = MIMEText(file_name+"文件超过限制，可能存在异常，请处理。项目为："+key) 
 msg = [key] 
 msg["From"]= MONITOR_CONFIG["send_account"] 
 msg["To"] = MONITOR_CONFIG["rec_account"] 
 try: 
  s = smtplib.SMTP_SSL(MONITOR_CONFIG["host"],MONITOR_CONFIG["port"]) 
  s.login(MONITOR_CONFIG["send_account"],MONITOR_CONFIG["license_code"]) 
  s.sendmail(MONITOR_CONFIG["send_account"],MONITOR_CONFIG["rec_account"],msg.as_string()) 
  s.quit() 
  logging.info(file_name + "警告发送成功") 
 except Exception as e: 
  logging.exception(e) 
 
# check 
while True: 
 for file in MONITOR_CONFIG["monitor_file"]: 
  file_size = get_file_size(file["path"]) 
  if file_size > file["max_size"]: 
   send_email(file["path"],file["key"]) 
 logging.info("检查完毕") 
 time.sleep(MONITOR_CONFIG["sleep_time"])

三、需在QQ邮箱设置开启POP3/SMTP服务
