数据库分析

对部分数据库中的数据进行分析

device_db

在device表中，会储存配对的设备的信息

如上图所示，连接的设备为Redmi 手表 2，它的设备id是513932244，mac地址44:27:F3:38:D9:D8，配对的手机的设备id是e9d158d9-e284-476e-8cf3-418c5fd286a0，sn序列号是35796/AGAAJF1Y401267

fitness_user

在user_info_profile表中，储存了用户信息，如id、性别、身高、体重、生日等信息

如上图所示，用户id为2452837599，性别为男，生日为2001-03-25，体重为60KG

fitness_sync

在device_sync表中，储存对应设备可以同步的信息，以二进制储存

fitness_data

保存在fitness_user.user_info_profile中的name字段的值同名的文件夹下

在hr_record表中，每半个小时插入一条心率数据

在sleep_segment表中，会记录睡眠数据

内容如下

{
  "avg_hr":68,//平均心率
  "bedtime":1662995880,//进入睡眠的时间
  "sleep_deep_duration":110,//深度睡眠时长
  "device_bedtime":1662995880,
  "device_wake_up_time":1663022040,//苏醒时间
  "sleep_light_duration":325,//浅睡眠时长
  "max_hr":79,//最大心率
  "min_hr":57,//最小心率
  "protoTime":1663022040,
  "duration":435,//睡眠总时长
  "items":[{
    "end_time":1663000486,
    "state":3,//浅睡眠
    "start_time":1662995880},
    {
      "end_time":1663006447,
      "state":2,//深度睡眠
      "start_time":1663000486},
    {
      "end_time":1663013006,
      "state":3,
      "start_time":1663006447},
    {
      "end_time":1663013602,
      "state":2,
      "start_time":1663013006},
    {
      "end_time":1663019280,
      "state":3,
      "start_time":1663013602},
    {
      "end_time":1663019340,
      "state":5,//清醒
      "start_time":1663019280},
    {
      "end_time":1663022040,
      "state":3,
      "start_time":1663019340}],
  "timezone":32,
  "version":2,
  "awake_count":1,//清醒次数
  "sleep_awake_duration":1,//清醒时长
  "wake_up_time":1663022040//苏醒时间
}

在spo2_record表中会记录血氧饱和度

在stand_record表中会记录有效站立，值为站立起始时间和结束时间

在step_record表中会记录每次行走的时间、卡路里、距离和步数

在stress_record表中会记录压力数据

在temperature_record表中会记录温度数据

fitness_summary

在daily_report表中，每天北京时间8点整会更新数据，包括数据的类型和值

以步数举例，值的形式以字典加列表保存

下面是值及解释

{
  "activeStageList":[],
  "calories":133, //消耗了133卡路里
  "distance":3104, //行走距离为3104米
  "maxEndTime":1663450500,
  "minStartTime":1663396380,
  "sid":"default",
  "stepRecords":[ //每半个小时统计消耗的卡路里、行走的距离和步数

}

APK分析

在之前数据分析时已经知道了一个表hr_record，直接跟着这个表的操作一步一步往上扒

找到同步包

一直抓不到蓝牙包，逆起来看构造又太麻烦，先留坑。。
