讀取睡眠資料

睡眠以時段表示 類型為 sleep。 時段可選擇包含睡眠階段，這些階段較為精細 關於睡眠資料例如淺睡、熟睡或 REM 睡眠 睡眠：

睡眠階段值

睡眠階段類型	值
清醒 (睡眠週期內)	1
睡眠	2
戶外床	3
淺層睡眠	4
深層睡眠	5
快速動眼期	6

「寫入睡眠資料」指南會說明 精細和非精細的睡眠資料會顯示在 Fit 中。

Android

下列範例使用 SessionClient 從 Fit 擷取資料。

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 擷取睡眠時段分為兩個階段：

1. 擷取工作階段清單 將 activityType 參數設為 72 (SLEEP)。 注意：您可以使用 startTime 和 endTime 或使用 pageToken ，擷取自上次要求以來的新工作階段。

   HTTP 方法

   GET
   

   要求網址

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

   回應

   工作階段範例 可能是：

   如果要求成功，您會收到 200 OK HTTP 回應狀態 再也不是件繁重乏味的工作回應主體包含活動的 JSON 表示法 構成睡眠時段的區段每個 intVal 都代表 睡眠活動類型
