Method: projects.operations.wait
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。
等到指定的长时间运行的操作完成，或最多达到指定的超时，从而返回最新状态。如果操作已完成，则立即返回最新状态。如果指定的超时大于默认的 HTTP/RPC 超时，则使用 HTTP/RPC 超时。如果服务器不支持此方法，则会返回 google.rpc.Code.UNIMPLEMENTED。请注意，此方法会尽力执行命令。它可能会在未达到指定的超时之前返回最新状态（包括立即返回），也就是说，即使立即收到响应，也并不保证操作已完成。
HTTP 请求
POST https://earthengine.googleapis.com/v1alpha/{name=projects/*/operations/**}:wait
网址采用 gRPC 转码语法。
路径参数
| 参数 |
name |
string
要等待的操作资源的名称。
|
请求正文
请求正文中包含结构如下的数据：
| JSON 表示法 |
{
"timeout": string
} |
| 字段 |
timeout |
string (Duration format)
超时之前等待的最长时间。如果将此字段留空，则等待时间最长为底层 HTTP/RPC 协议允许的时间。如果还指定了 RPC 上下文截止时间，则以二者中较短者为准。 该时长以秒为单位，最多包含九个小数位，以“s”结尾。示例："3.5s"。

响应正文
如果成功，则响应正文包含一个 Operation 实例。
