ee.data.getOperation
使用集合让一切井井有条
根据您的偏好保存内容并对其进行分类。
获取有关某项操作或一系列操作的信息。
如需详细了解操作，请访问：https://cloud.google.com/apis/design/design_patterns#long_running_operations
返回操作状态，或从操作名称到状态的映射。每项操作都包含：
- name：操作名称，格式为 projects/X/operations/Y
- done：当操作已完成运行时，为 true。
- error：可能会在 done=true 时设置。包含来自 https://cloud.google.com/tasks/docs/reference/rpc/google.rpc#status 的消息和其他字段
- 元数据，其中包含
+ state：PENDING、RUNNING、CANCELLING、SUCCEEDED、CANCELLED 或 FAILED
+ description：提供的任务说明
+ 类型：EXPORT_IMAGE、EXPORT_FEATURES 等。
+ create_time：操作的首次提交时间。
+ update_time：最近一次更新的时间戳。
+ start_time：操作开始时间（如有）。
+ end_time：操作完成运行的时间（如有）。
+ attempt：此任务的重试次数，从 1 开始。
+ destination_uris：相应操作输出的资源。
+ batch_eecu_usage_seconds：相应操作使用的 CPU。
