通过邮件发送树莓派IP地址

获取树莓派地址的方法有很多，如通过终端下输入命令ifconfig查看，通过串口输入命令ifocnfig查看，甚至还可以通过语音播报的方式查看。接下来我们说下通过邮件的方式将树莓派IP地址发送到指定的邮箱的方法。先上代码：

import os
import io
import time
import logging
import socket
import smtplib
import subprocess
import traceback
from email.mime.text import MIMEText
from email.utils import formataddr
from threading import Thread

class IPs(object):
    def __init__(self, config, udp, mail):
        self._vps_ip = config['vps_ip']
        self._vps_port_udp = config['vps_udp_port']

        self._is_udp = udp
        self._is_mail = mail
        self._addrs = self._get_local_ip()

    def start(self):
        try:
            #ip_thd = Thread(target = self._ip_worker, args = (), daemon=True)
            ip_thd = Thread(target = self._ip_worker)
            ip_thd.start()
        except:
            traceback.print_exc()
            logging.error('Thread create failed.[ip_thd].')

    def test(self):
        for i in range(5):
            print('test ',i)
            time.sleep(1)

    def _ip_worker(self):
        info_dict ={'my_ip_info':''}
        while True:
            print("running")
            logging.debug('curl ip')
            proc = subprocess.Popen('curl icanhazip.com', shell=True, \
                stdout=subprocess.PIPE, stderr=subprocess.DEVNULL, bufsize=-1)
            proc.wait()
            stream_stdout = io.TextIOWrapper(proc.stdout, encoding='utf-8')
            ip_info = str(stream_stdout.read()).strip()
            logging.debug('curl ip got:%s' % ip_info)

            if ip_info not in info_dict['my_ip_info']:
                if self._ip_trans(ip_info) == True:
                    info_dict['my_ip_info'] = ip_info
                    logging.info('Sent success:%s.' % ip_info)
                else:
                    logging.error('ip_trans failed.')
            time.sleep(600)

    def _ip_trans(self, ip_info):
        if self._is_udp:
            udp_res = self._udp_ip()
        else:
            udp_res = True
        if self._is_mail:
            mai_res = self._mail_ip(ip_info)
        if udp_res and mai_res:
            return True
        else:
            return False

    def _mail_ip(self, ip_str):
        my_email_sender='[email protected]'        # may subject to change
        my_email_passwd = 'your password'       # may subject to change
        recivers = ['[email protected]']          # may subject to change

        ip_list = []
        for ip in self._addrs:
            if str(ip[0]) == "AddressFamily.AF_INET":
                ip_str = ip_str + '\n' + ip[4][0]

        print(ip_str)

        try:
            for reciver in recivers:
                msg=MIMEText(ip_str, 'plain', 'utf-8')
                msg['From'] = formataddr(['Raspberry Pi', my_email_sender])
                msg['To'] = formataddr(['', reciver])
                msg['Subject'] = 'IP Address.'

                server=smtplib.SMTP_SSL('smtp.163.com', 465)        # may subject to change
                server.login(my_email_sender, my_email_passwd)
                server.sendmail(my_email_sender, [reciver,], msg.as_string())
                server.quit()
                logging.info('e-mail sent success:%s', ip_str)
        except Exception:
            traceback.print_exc()
            logging.error('e-mail sent failed:%s', ip_str)
            return False
        return True

    def _udp_ip(self):
        try:
            address = (self._vps_ip, self._vps_port_udp)
            so = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
            so.sendto('Fuck you.'.encode('utf-8'), address)
            so.close()
            return True
        except:
            so.clese()

    def _get_local_ip(self):

        addrs = socket.getaddrinfo(socket.gethostname(),None)
        return addrs

if __name__ == "__main__":
    config = {'vps_ip':'127.0.0.1', 'vps_udp_port':'10000'}
    udp = 0
    mail = 1
    new_IP = IPs(config, udp, mail)
    new_IP.start()

代码需要python3环境，不过不用担心，目前树莓派预置了python3解释器，如果不放心的话用下面的命令：

sudo apt-get install python3

代码比较简单，就不解释了，看看名字应该能懂。这个代码目前能够找到系统所有的IP地址，Windows，Linux和MacOS均可使用。效果：

开机启动

这个很重要，不然这代码就没有任何卵用了。方法如下：

将python代码保存到文件中，然后修改文件权限：

sudo chmod 777 文件名

将文件路径加到/etc/rc.local文件中，注意这里要在exit 0之前加入才会生效：

路径/文件名 start

大功告成！
