回到蘋果，開啟[偏好設定」的TimeMachine就可以抓到了喔！import subprocess import smtplib import socket from email.mime.text import MIMEText import datetime # 這裏改成自己的email to = 'example.com' gmail_user = 'test@gmail.com' gmail_password = 'gmail的密碼' smtpserver = smtplib.SMTP('smtp.gmail.com', 587) smtpserver.ehlo() smtpserver.starttls() smtpserver.ehlo smtpserver.login(gmail_user, gmail_password) today = datetime.date.today() # Very Linux Specific arg='ip route list' p=subprocess.Popen(arg,shell=True,stdout=subprocess.PIPE) data = p.communicate() split_data = data[0].split() ipaddr = split_data[split_data.index('src')+1] my_ip = 'Your ip is %s' % ipaddr msg = MIMEText(my_ip) msg['Subject'] = 'IP For RaspberryPi on %s' % today.strftime('%b %d %Y') msg['From'] = gmail_user msg['To'] = to smtpserver.sendmail(gmail_user, [to], msg.as_string()) smtpserver.quit()
python /home/pi/Code/startup_mailer.py就會寄一封信，到你指定的信箱中，告訴你的Pi流浪到哪裡去了！
