管理資料來源
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
Fitness REST API 可讓您建立、取得及更新資料來源。資料來源是指
是獨一無二的感應器資料來源您會使用資料來源將健身資料插入健身類別
儲存，您可以擷取由特定資料來源插入的健身資料。
資料來源會以 Users.dataSources 表示
資源。
建立資料來源

再也不是件繁重乏味的工作回應主體包含資料來源的 JSON 表示法，
包括 datasource.dataStreamId
資源，可做為後續要求的資料來源 ID。

A data source represents\na unique source of sensor data. You use data sources to insert fitness data into the fitness\nstore, and you can retrieve fitness data inserted by a particular data source.\n\nData sources are represented by the [`Users.dataSources`](/fit/rest/v1/reference/users/dataSources)\nresource.\n| **Important:** For best practices when managing user data, see [Responsible use of Google Fit](/fit/overview#responsible_use_of_google_fit).\n\nCreate a data source\n--------------------\n\nThis example demonstrates how to create a new data source named \"MyDataSource\"\nthat provides step count increments.\n\nHTTP method\n: POST\n\nRequest URL\n: `https://www.googleapis.com/fitness/v1/users/me/dataSources`\n\nRequest body\n:\n\n {\n \"dataStreamName\": \"MyDataSource\",\n \"type\": \"derived\",\n \"application\": {\n \"detailsUrl\": \"http://example.com\",\n \"name\": \"Foo Example App\",\n \"version\": \"1\"\n },\n \"dataType\": {\n \"field\": [\n {\n \"name\": \"steps\",\n \"format\": \"integer\"\n }\n ],\n \"name\": \"com.google.step_count.delta\"\n },\n \"device\": {\n \"manufacturer\": \"Example Manufacturer\",\n \"model\": \"ExampleTablet\",\n \"type\": \"tablet\",\n \"uid\": \"1000001\",\n \"version\": \"1.0\"\n }\n }\n\nResponse\n\n: If the data source is created successfully, the response is a `200 OK` status\n code.
