python 接收蓝牙网关代码（已解决）

这是mqtt的代码  可以为后面写http通信的数据解析做参考 

完全可以测通的（是因为防火墙的问题）

原因：开启了防火墙在本地是可以测通的  外面的机器是访问不了我的电脑的

解决办法：关闭防火墙就可以了  

存在问题： 貌似没有做任何处理的http包 会存在粘包现象 不定时的的报错 因为用的式异步框架 所以不影响整体运行，但会丢失一部分数据（现改用mqtt通信模式）

有用的代码

    tornado.ioloop.IOLoop.instance().start()

初级+  可以查看每秒内的蓝牙广播设备数量（但不是广播数据量）

import tornado.ioloop
import tornado.web
import msgpack
from binascii import *
class MainHandler(tornado.web.RequestHandler):
    def get(self):
        print('get')
        self.write("Hello, get")
        
    def post(self):
#         print('post')
        package =  self.request.body
        data = msgpack.unpackb(package,use_list=False, raw=False)
        brocast_data = data['devices']
        outData={'header':"",'payload':[]}
        mac_data = set()
        for b in brocast_data:
            record={};
            data_bro={};            
            try:
                record=b2a_hex(b)
                data_bro['type']=hex(int(record[:2],16))
                data_bro['mac']=hex(int(record[2:14],16))
                data_bro['rssi']=hex(int(record[14:16],16))
                data_bro['broadcast_data']=hex(int(record[16:],16))
                mac_data.add(data_bro['mac'])
            except:
                pass;
            outData['payload'].append(data_bro);
        print(len(mac_data))

if __name__ == "__main__":
    application = tornado.web.Application([(r"/", MainHandler),])
    application.listen(1883,'10.33.4.31')
    tornado.ioloop.IOLoop.instance().start()

输出：

偶尔打印异常
