python监控网站更新_Python 通过网站search功能监控网站内容更新[通俗易懂]

大家好，又见面了，我是你们的朋友全栈君。

接到需求帮朋友监控一个信息网站,当该网站有相关的数据更新的时候发送信息到指定邮箱.下面是相关的python脚本,用到了httplib, time , sys ,smtplib模块

#!/usr/bin/env python#coding=utf8import httplib, timeimport sysimport smtplib

reload(sys)

sys.setdefaultencoding(‘utf8’)from email.mime.text import MIMEText

mailto_list=[‘sendmail@126.com’]

mail_host=”smtp.sina.com”mail_user=”sendmailaccount”mail_pass=”sendmailpassword”mail_postfix=”sina.com”sec=60conn = httplib.HTTPConnection(“网站地址”)

conn.request(“GET”, “搜索后的网站地址|/caigou/kw-%E6%B1%A1%E6%B0%B4%E5%A4%84%E7%90%86%E6%8B%9B%E6%A0%87.html”)

r1 = conn.getresponse()

a = r1.read()defsend_mail(to_list,sub,content):me=”网站信息已更新”+””msg = MIMEText(content,_subtype=’html’,_charset=’utf8′)

msg[‘Subject’] = sub

msg[‘From’] = me

msg[‘To’] = “;”.join(to_list)try:

s = smtplib.SMTP()

s.connect(mail_host)

s.login(mail_user,mail_pass)

s.sendmail(me, to_list, msg.as_string())

s.close()returnTrueexcept Exception, e:print str(e)returnFalseprint”The program is starting”whileTrue:

time.sleep( sec )

b = r1.read()if a == b:print’good running ,Now it is ‘ + time.strftime(‘%Y年%m月%d日,%H:%M:%S’)+ ‘\n请稍后…..’else:print”网站更新”if __name__ == ‘__main__’:if send_mail(mailto_list, “网站信息已更新”, “对应网站域名”): print”发送成功”else: print”发送失败”

a = r1.read()
