欄位 |
name |
string
伺服器指派的名稱,而且只在當初傳回這個名稱的服務中是唯一的。如果您使用預設的 HTTP 對應,則 name 應該是以 operations/{unique_id} 結尾的資源名稱。
|
metadata |
object
服務專屬,且與該作業相關聯的中繼資料,通常包含進度資訊和常用中繼資料 (例如建立時間)。部分服務可能不會提供這類中繼資料。凡是會傳回長時間執行作業的方法,都應記錄中繼資料類型 (如果有的話)。 包含任意類型欄位的物件。額外的 "@type" 欄位則包含能辨識類型的 URI。範例:{ "id": 1234, "@type": "types.example.com/standard/id" } 。
|
done |
boolean
如果值為 false ,代表作業仍在執行中。如果值為 true ,代表作業已執行完畢,系統會顯示 error 或 response 的執行結果。
|
聯集欄位 result 。這是作業的執行結果,可能為 error ,或是有效的 response 。如果 done == false ,系統不會將結果設定為 error ,也不會設定為 response 。如果 done == true ,系統會將結果設定為 error 或 response 。部分服務可能不會提供結果。result 只能是下列其中一個設定: |
error |
object (Status )
作業執行失敗或遭到取消時,所顯示的錯誤結果。
|
response |
object
作業執行成功時的一般回應。如果原始方法在執行成功時沒有傳回資料 (例如 Delete ),則回應為 google.protobuf.Empty 。如果原始方法是標準的 Get /Create /Update ,回應則應該為資源。如果是其他方法,回應必須包含類型 XxxResponse ,其中 Xxx 是原始方法的名稱。舉例來說,如果原始方法的名稱為 TakeSnapshot() ,您就能推測出回應類型應該是 TakeSnapshotResponse 。 包含任意類型欄位的物件。額外的 "@type" 欄位則包含能辨識類型的 URI。範例:{ "id": 1234, "@type": "types.example.com/standard/id" } 。

|
刪除長時間執行的作業。 |
|
取得長時間執行的作業的最新狀態。 |
|
列出符合要求中指定篩選器的作業。 |
|
等待指定的長時間執行作業完成,或是最多等到指定的逾時時間為止,並傳回最新狀態。 |

If you use the default HTTP mapping, the `name` should be a resource name ending with `operations/{unique_id}`. |\n| `metadata` | `object` Service-specific metadata associated with the operation. It typically contains progress information and common metadata such as create time. Some services might not provide such metadata. Any method that returns a long-running operation should document the metadata type, if any. An object containing fields of an arbitrary type. An additional field `\"@type\"` contains a URI identifying the type. Example: `{ \"id\": 1234, \"@type\": \"types.example.com/standard/id\" }`. |\n| `done` | `boolean` If the value is `false`, it means the operation is still in progress. If `true`, the operation is completed, and either `error` or `response` is available. |\n| Union field `result`. The operation result, which can be either an `error` or a valid `response`. If `done` == `false`, neither `error` nor `response` is set. If `done` == `true`, exactly one of `error` or `response` can be set. Some services might not provide the result. `result` can be only one of the following: ||\n| `error` | `object (`[Status](/earth-engine/reference/rest/Shared.Types/ListOperationsResponse#Status)`)` The error result of the operation in case of failure or cancellation. |\n| `response` | `object` The normal, successful response of the operation. If the original method returns no data on success, such as `Delete`, the response is `google.protobuf.Empty`. If the original method is standard `Get`/`Create`/`Update`, the response should be the resource. For other methods, the response should have the type `XxxResponse`, where `Xxx` is the original method name. For example, if the original method name is `TakeSnapshot()`, the inferred response type is `TakeSnapshotResponse`. An object containing fields of an arbitrary type. An additional field `\"@type\"` contains a URI identifying the type.
