DIY个人智能家庭网关——python篇之推送门磁报警信息到手机

见《通过openwrt推送门磁报警信息到android手机上》

python代码如下

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import serial
from time import sleep
import json
import subprocess

ser = serial.Serial('/dev/ttyUSB0', 9600, timeout=0.5)

print ser.port
print ser.baudrate

my_addr = "0x5555"

def push_msg(msg):
content = {"platform":"all","audience":"all", "notification":{"alert":msg}}
print content
json_str = json.dumps(content)
print json_str
cmd = "curl -X POST --cacert /etc/ssl/certs/ca-certificates.crt -v https://api.jpush.cn/v3/push/ -H \"Content-Type: application/json\" -u \"xxx:xxx\""
curl_cmdline = '%s -d \'%s\''%(cmd,json_str)
print curl_cmdline
rc = subprocess.call(curl_cmdline, shell=True);

def recv(serial):
while True:
data =serial.read(64)
if data == '':
continue
else:
break
sleep(0.02)
return data

while True:
data =recv(ser)
if data != '':
print data
s = json.loads(data)
print s["addr"]
if s["addr"] == my_addr:
push_msg("Alarm!!!")
