Bắt đầu huỷ không đồng bộ trên một thao tác chạy trong thời gian dài. Máy chủ sẽ cố gắng hết sức để huỷ thao tác, nhưng không đảm bảo sẽ huỷ thành công. Nếu không hỗ trợ phương thức này, máy chủ sẽ trả về google.rpc.Code.UNIMPLEMENTED. Ứng dụng có thể sử dụng Operations.GetOperation hoặc các phương thức khác để kiểm tra xem thao tác huỷ có thành công hay không hoặc liệu thao tác có hoàn tất mặc dù đã huỷ hay không. Khi huỷ thành công, thao tác sẽ không bị xoá; thay vào đó, thao tác đó sẽ trở thành một thao tác có giá trị Operation.error với google.rpc.Status.code là 1, tương ứng với Code.CANCELLED.

The server makes a best effort to cancel the operation, but success is not guaranteed. If the server doesn't support this method, it returns `google.rpc.Code.UNIMPLEMENTED`. Clients can use `Operations.GetOperation` or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an [Operation.error](/gemini/docs/api/reference/rest/v1/projects.locations.operations#Operation.FIELDS.error) value with a [google.rpc.Status.code](/gemini/docs/api/reference/rest/v1/projects.locations.operations#Status.FIELDS.code) of `1`, corresponding to `Code.CANCELLED`.\n\n### HTTP request\n\n`POST https://cloudaicompanion.googleapis.com/v1/{name=projects/*/locations/*/operations/*}:cancel`\n\nThe URL uses [gRPC Transcoding](https://google.aip.dev/127) syntax.\n\n### Path parameters\n\n### Request body\n\nThe request body must be empty.\n\n### Response body\n\nIf successful, the response body is an empty JSON object.\n\n### Authorization scopes\n\nRequires the following OAuth scope:\n\n- `https://www.googleapis.com/auth/cloud-platform`\n\nFor more information, see the [Authentication Overview](/docs/authentication#authorization-gcp).\n\n### IAM Permissions\n\nRequires the following [IAM](https://cloud.google.com/iam/docs) permission on the `name` resource:\n\n- `cloudaicompanion.operations.cancel`\n\nFor more information, see the [IAM documentation](https://cloud.google.com/iam/docs)."]]
