前言
因為有一些網站需要每日檢查是否有問題，所以需要一個報警監控的機制，這個需要你指定你發送的郵箱和你接收的郵箱，就可以做到對網站自動監控了。
這里用的是python3.5
需要安裝的插件:
1、smtplib:發郵件需要用到
2、pycurl:訪問網站時會需要用到
3、linecache:在讀取txt網站清單時需要用到
具體思路:
python程序從txt里面批量讀取到網站的信息,通過Curl.py模擬瀏覽器去訪問網站,并且把訪問的結果寫入到以自己的網站名稱-日期.txt格式的文件中記錄;有幾種情況:
1、如果發現打不開了,直接發郵件提示網站已經打不開
2、發現可以打開,讀取文件中上一次訪問的情況(讀取txt文件最后一行),
1)如果發現上一次是打不開的,發郵件提醒網站已經恢復了
2)如果發現上一次是打得開的(200的返回碼),只是記錄網站訪問的日志就可以了
總共4個文件
Email.py是郵件類,主要用來發郵件的時候調用,這里需要按照你的情況改成你的郵箱(msg['From']),郵箱服務器地址(SMTP地址),和你的郵箱密碼(SMTP.login)
Email.py
#!/usr/bin/python#-*- coding:utf-8 -*-import sysimport smtplibfrom email.mime.text import MIMETextfrom email.mime.multipart import MIMEMultipartclass Email_send(object): def __init__(self,msgTo,data2,Subject): self.msgTo=msgTo self.data2=data2 self.Subject=Subject def sendEmail(self): # (attachment,html) = content msg = MIMEMultipart() msg['Subject'] = self.Subject msg['From'] = 'xxxx@xxxx.com.cn' msg['To'] = self.msgTo html_att = MIMEText(self.data2, 'html', 'utf-8') #att = MIMEText(attachment, 'plain', 'utf-8') msg.attach(html_att) #msg.attach(att) try: smtp = smtplib.SMTP() smtp.connect('smtp.xxxx.com', 25) smtp.login(msg['From'], 'xxxx') #改成自己的郵箱密碼 smtp.sendmail(msg['From'], msg['To'].split(','), msg.as_string()) return('郵件發送成功') except Exception as e: print('--------------sss------',e) def curl(self): import pycurl c=pycurl.Curl() #url="www.luoan.com.cn" #indexfile=open(os.path.dirname(os.path.realpath(__file__))+"/content.txt","wb") c.setopt(c.URL,url) c.setopt(c.VERBOSE,1) c.setopt(c.ENCODING,"gzip") #模擬火狐瀏覽器 c.setopt(c.USERAGENT,"Mozilla/5.0 (Windows NT 6.1; rv:35.0) Gecko/20100101 Firefox/35.0") return cCurl.py 主要用來執行模擬瀏覽器訪問網站并返回結果的文件
#!/usr/bin/python#-*- coding:utf-8 -*-import sysimport pycurlclass Curl(object): def __init__(self,url): self.url=url def Curl_site(self): c=pycurl.Curl() #url="www.luoan.com.cn" #indexfile=open(os.path.dirname(os.path.realpath(__file__))+"/content.txt","wb") c.setopt(c.URL,self.url) c.setopt(c.VERBOSE,1) c.setopt(c.ENCODING,"gzip") #模擬火狐瀏覽器 c.setopt(c.USERAGENT,"Mozilla/5.0 (Windows NT 6.1; rv:35.0) Gecko/20100101 Firefox/35.0") return c
site_moniter.py 這個文件為主程序,主要執行調用上面的函數,讀取txt文件中的網站清單,如果網站打不開就發郵件出來告警
需要注意:
1、把xxxx@xxxx.com改成你自己的郵箱,
2、把文件路徑改成自己的真實路徑

利用Python自動監控網站并發送郵件告警的方法到這就基本結束了，希望對大家的學習工作能有所幫助。
