DIY個人智能家庭網關——python篇之推送門磁報警信息到手機

見《通過openwrt推送門磁報警信息到android手機上》

python代碼如下

#!/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!!!")
