添加营养数据

您可以向 Google 健身添加营养数据，只需创建数据源并使用 com.google.nutrition 数据类型。每个数据点都代表 膳食或零食中消耗的所有营养素的比例。此示例展示了如何将 营养数据。

创建数据源

Android

使用 DataSource.Builder 创建新的数据源。例如 nutritionSource。

val nutritionSource = DataSource.Builder()
    .setDataType(DataType.TYPE_NUTRITION)
    // ...
    .build()

REST

调用 REST API 以创建新的数据源。例如 NutritionSource。

HTTP 方法

POST

Request URL

{
  "dataStreamName": "NutritionSource",
  "type": "raw",
  "application": {
    "detailsUrl": "http://example.com",
    "name": "My Example App",
    "version": "1"
  },
  "dataType": {
    "name": "com.google.nutrition",
   }
}

添加营养数据

Android

此示例展示了如何创建新数据点和添加营养成分 香蕉的数据，使用 nutritionSource 数据源。

val nutrients = mapOf(
    Field.NUTRIENT_TOTAL_FAT to 0.4f,
    Field.NUTRIENT_SODIUM to 1f,
    Field.NUTRIENT_SATURATED_FAT to 0.1f,
    Field.NUTRIENT_PROTEIN to 1.3f,
    Field.NUTRIENT_TOTAL_CARBS to 27.0f,
    Field.NUTRIENT_CHOLESTEROL to 0.0f,
    Field.NUTRIENT_CALORIES to 105.0f,
    Field.NUTRIENT_SUGAR to 14.0f,
    Field.NUTRIENT_DIETARY_FIBER to 3.1f,
    Field.NUTRIENT_POTASSIUM to 422f
)
val banana = DataPoint.builder(nutritionSource)
    .setTimestamp(timestamp, TimeUnit.MILLISECONDS)
    .setField(Field.FIELD_FOOD_ITEM, "banana")
    .setField(Field.FIELD_MEAL_TYPE, Field.MEAL_TYPE_SNACK)
    .setField(Field.FIELD_NUTRIENTS, nutrients)
    .build()

REST

此示例展示了如何使用 NutritionSource 数据源。营养数据类型的值是 营养成分（地图）、膳食类型（4 = “零食”）和实际的菜品 （字符串）。
