查询器件

想根据product_key和mac查询设备，获取did,发送数据包如下：
GET /app/devices?product_key=7fbb80daadd444a3a2c193e5ce31f2b9&mac=F0DEF1B61D3E HTTP/1.1
Host: api.gizwits.com
Connection: keep-alive
Accept: */*
X-Gizwits-Application-Id: c99304b8eeea4f52b9ec7b88a3999c86
Content-Type: application/json

平台回应：
HTTP/1.1 404 NOT FOUND
Server: nginx/1.0.15

Content-Type: application/json
