 1. 获取设备上传感器的数据，需要在“config.json”里面进行配置请求权限。具体如下：
   
    ```
-   ”reqPermissions“:[
-     {
-        "name":"ohos.permission.ACCELEROMETER",
-        "reason"":"", 
-        "usedScene":{
-         "ability": ["sensor.index.MainAbility",".MainAbility"],
-         "when":"inuse"
-       }
-     },
-     {
-        "name":"ohos.permission.GYROSCOPE",
-        "reason"":"", 
-        "usedScene":{
-         "ability": ["sensor.index.MainAbility",".MainAbility"],
-         "when":"inuse"
-       }
-     },
-     {
-        "name":"ohos.permission.ACTIVITY_MOTION",

-     },
-     {

-        "reason"":"HEALTH_DATA_TEST",
