读取睡眠数据

Android

以下示例使用 SessionClient 从 Google 健身检索数据。

val SLEEP_STAGE_NAMES = arrayOf(
    "Unused",
    "Awake (during sleep)",
    "Sleep",
    "Out-of-bed",
    "Light sleep",
    "Deep sleep",
    "REM sleep"
)

val request = SessionReadRequest.Builder()
    .readSessionsFromAllApps()
    // By default, only activity sessions are included, so it is necessary to explicitly
    // request sleep sessions. This will cause activity sessions to be *excluded*.
    .includeSleepSessions()
    // Sleep segment data is required for details of the fine-granularity sleep, if it is present.
    .read(DataType.TYPE_SLEEP_SEGMENT)
    .setTimeInterval(startTime, endTime, TimeUnit.MILLISECONDS)
    .build()

sessionsClient.readSession(request)
    .addOnSuccessListener { response ->
        for (session in response.sessions) {
            val sessionStart = session.getStartTime(TimeUnit.MILLISECONDS)
            val sessionEnd = session.getEndTime(TimeUnit.MILLISECONDS)
            Log.i(TAG, "Sleep between $sessionStart and $sessionEnd")

            // If the sleep session has finer granularity sub-components, extract them:
            val dataSets = response.getDataSet(session)
            for (dataSet in dataSets) {
                for (point in dataSet.dataPoints) {
                    val sleepStageVal = point.getValue(Field.FIELD_SLEEP_SEGMENT_TYPE).asInt()
                    val sleepStage = SLEEP_STAGE_NAMES[sleepStageVal]
                    val segmentStart = point.getStartTime(TimeUnit.MILLISECONDS)
                    val segmentEnd = point.getEndTime(TimeUnit.MILLISECONDS)
                    Log.i(TAG, "\t* Type $sleepStage between $segmentStart and $segmentEnd")
                }
            }
        }
    }

REST

使用 REST API 检索睡眠时段的过程分为两个阶段：

1. 检索会话列表 将 activityType 参数设为 72 (SLEEP)。 注意：您可以使用 startTime 和 endTime，也可以使用 pageToken 检索自上次请求之后的新会话。

   HTTP 方法

   GET
   

   Request URL

   https://www.googleapis.com/fitness/v1/users/me/sessions?startTime=2019-12-05T00:00.000Z&endTime=2019-12-17T23:59:59.999Z&activityType=72
   

   答案

   Session 示例 可能是：

   {
    "session": [
       {
        "id": "Sleep1575505620000",
        "name": "Sleep",
        "description": "",
        "startTimeMillis": "1575505620000",
        "endTimeMillis": "1575526800000",
        "modifiedTimeMillis": "1575590432413",
        "application": {
         "packageName": "com.example.sleep_tracker"
        },
        "activityType": 72  // Sleep
       },
       {
        "id": "Run2939075083",
        "name": "Mud",
        "description": "",
        "startTimeMillis": "1576594403000",
        "endTimeMillis": "1576598754000",
        "modifiedTimeMillis": "1576616010143",
        "application": {
         "packageName": "com.example.run_tracker"
        },
        "activityType": 8  // Running
       }
     ],
    "deletedSession": [],
    "nextPageToken": "1576598754001"
   }
   

2. 如要获得每个时段的睡眠阶段详细信息（如果存在），请使用 针对已过滤列表中的每个会话发出以下请求：

   HTTP 方法

   POST
   

   Request URL

   https://www.googleapis.com/fitness/v1/users/userId/dataset:aggregate
   

   请求正文

   {
     "aggregateBy": [
       {
         "dataTypeName": "com.google.sleep.segment"
       }
     ],
     "endTimeMillis": 1575609060000,
     "startTimeMillis": 1575591360000
   }
   

   答案

   如果请求成功，您会收到 200 OK HTTP 响应状态 代码。响应正文包含活动的 JSON 表示法 组成睡眠时段的片段。每个 intVal 表示 睡眠活动类型

   {
    "bucket": [
     {
      "startTimeMillis": "1575591360000",
      "endTimeMillis": "1575609060000",
      "dataset": [
       {
        "point": [
         {
          "startTimeNanos": "1575591360000000000",
          "endTimeNanos": "1575595020000000000",
          "dataTypeName": "com.google.sleep.segment",
          "originDataSourceId": "...",
          "value": [
           {
            "intVal": 4, // Light sleep
            "mapVal": []
           }
          ]
         },
         {
          "startTimeNanos": "1575595020000000000",
          "endTimeNanos": "1575596220000000000",
          "dataTypeName": "com.google.sleep.segment",
          "originDataSourceId": "...",
          "value": [
           {
            "intVal": 1, // Sleep
            "mapVal": []
           }
          ]
         },
   
         // .... more datapoints
   
         {
          "startTimeNanos": "1575605940000000000",
          "endTimeNanos": "1575609060000000000",
          "dataTypeName": "com.google.sleep.segment",
          "originDataSourceId": "...",
          "value": [
           {
            "intVal": 4, // Light sleep
            "mapVal": []
           }
          ]
         }
        ]
       }
      ]
     }
    ]
   }
