树莓派开机自动检测并发送IP地址到指定邮箱

在不固定的网络环境下（如出差），IP地址是不固定的，每次都用网线连接电脑查看太麻烦，开发LED屏显示IP地址更耗时间，今天突然想到，可以写个脚本，开机自动检测IP发送到我的邮箱，比较方便。

python的网络功能强大，遂使用python编写脚本，参照的网络文章。

参考文章：http://blog.csdn.net/u013151320/article/details/50251959

一. 新建一个python脚本文件

[johnwick@raspberrypi~]$nano send_ip.py

二. 编辑脚本内容

1. 获取python的位置

   [johnwick@raspberrypi~]$which python/usr/bin/python  

   1. 编写代码 （未进行检查（有相当多的错误）没有错误提示的代码请看内容 4）

      #!/usr/bin/python#-*-coding:utf-8-*-import socketimport timeimport smtplibimport urllibfrom email.mine.multipart import MIMEMultipartfrom email.mime.text import MIMETextfrom email.mime.image import MIMEImage    def sendEmail(smtpserver,username,password,sender,receiver,subject,msghtml):msgRoot =MIMEMultipart('reklated')msgRoot['to']=','.join(receiver)msgRoot['Subject']= subjectmsgText = MIMEText(msghtml,'html','utf-8')msgRoot.attach(msgText)smtp = smtplib.SMTP()smtp.connect(smtpserver,"25")smtp.login(username,password)print "yes"smtp.quit()#检查网络连通性def check_network()        while True:            try:                result=urllib.urlopen('http://baidu.com').read()                print result                print "Network is Ready!"                break          except Exception , e:                print e                print "Network is not ready,Sleep 5s..."                time.sleep(5)        return True#获取 本级制定接口的IP地址    def get_ip_address():            s =socket.socket(socket.AF_INET,socket.SOCK_DGRAM)            s.connect(("1.1.1.1",80))            ipaddr=s.getsockname()[0]            s.close()            return ipaddr    if  __name__ == '__main__' :            check_network()            ipaddr= get_ip_address()            sendEmail("smtp.sohu.com",'你的邮箱帐号','你的邮箱密码','发件人地址',['收件人地址'],'IP Address of Raspberry PI',ipaddr)

   期间调试发现，因为复制粘贴，出现了相当多的错误提示
   大部分都是因为不正确地使用缩进量。
   由于python语法对缩进量的要求极为严格（比如：同级语句缩进量必须相同、禁止空格和tab混用）

   1. 大部分的操作记录如下：

   2. 没有错误提示的代码

      #!/usr/bin/python#-*-coding:utf-8-*-import socketimport timeimport smtplibimport urllibfrom email.mime.multipart import MIMEMultipartfrom email.mime.text import MIMETextfrom email.mime.image import MIMEImagedef sendEmail(smtpserver,username,password,sender,receiver,subject,msghtml): msgRoot = MIMEMultipart('reklated') msgRoot['to']=','.join(receiver) msgRoot['Subject']= subject msgText = MIMEText(msghtml,'html','utf-8') msgRoot.attach(msgText) smtp = smtplib.SMTP() smtp.connect(smtpserver,"25") smtp.login(username,password) print "yes" smtp.quit()    #检查网络连通性def check_network():        while True:                try:                        result=urllib.urlopen('http://baidu.com').read()                        print result                        print "Network is Ready!"                        break                except Exception , e:                        print e                        print "Network is not ready,Sleep 5s..."                        time.sleep(5)        return True#获取 本级制定接口的IP地址def get_ip_address():        s =socket.socket(socket.AF_INET,socket.SOCK_DGRAM)        s.connect(("0.0.0.0",80))        ipaddr=s.getsockname()[0]        s.close()        return ipaddrif  __name__ == '__main__' :        check_network()        ipaddr= get_ip_address()        sendEmail('smtp.163.com','[e-mail]','2345125241241','[e-mail]',['[e-mail]'],'IP Address of Raspberry PI',ipaddr)

   3. 执行情况：

   执行后没发送邮件，只进行了网络连通性检测，没有错误提示

   [johnwick@raspberrypi~]$python send_ip.py<html><meta http-equiv="refresh" content="0;url=http://www.baidu.com/"></html>Network is Ready!yes

   细节：
   选择发送邮件的邮箱后（我想用[e-mail]作为代理邮箱，通过smtp 服务代理发送，但是网易的安全策略相当严格，使用SMTP服务需要进行验证）

   加上使用sendmail服务发送邮件有一些相当复杂且严谨的配置。

   所以后来使用了msmtp+mutt+shell脚本的方式成功实现了开机检测IP并发送到指定邮箱。
