ee.data.listFeatures
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
列出指定表格資產的特徵。
傳回通話結果。如果指定回呼，則為空值。
| 用量 | 傳回 |
|---|
ee.data.listFeatures(asset, params, callback) | api.ListFeaturesResponse |
| 引數 | 類型 | 詳細資料 |
|---|
asset | 字串 | 要查詢的資料表資產 ID。 |
params | api.ProjectsAssetsListFeaturesNamedParameters | 物件，內含要求參數，可能的值如下：
pageSize (數字)：每頁的結果數上限 (選用)，預設為 1000。 |
pageToken (字串)：選用符記，用於識別伺服器應傳回的結果頁面，通常取自回應物件。 |
region (字串)：如有，則為定義查詢區域的幾何圖形，指定為 GeoJSON 幾何圖形字串 (請參閱 RFC 7946)。 |
filter (以半形逗號分隔的字串)：如有，則指定其他簡單的屬性篩選條件 (請參閱 https://google.aip.dev/160)。 |
|
callback | 函式 (選用) | 選用回呼，會使用兩個參數呼叫：第一個是產生的特徵清單，第二個是失敗時的錯誤字串。如未提供，系統會同步發出呼叫。 |
