python 写入json数据到数据库

json数据格式：

# json格式数据
data={
   "camera": {
      "created": "1531925035",
      "type": 1,
      "description": "A bridge is a structure that is built over a railway, river, or road so that people or vehicles can cross from one side to the other.",
      "location": {
         "locationID":"1",
         "country": "china",
         "city": "xian",
         "region": "changanqu"
      },
      "project_id": "Golden Gate Bridge",
      "task_id": "23232",
      "camera_id": "23232",
      "mu": "mm",
      "value": {
         "x": "123123",
         "y": "123123"
      },
      "ext_info": "null"
   }
