amazon-web-services - AWS 存储网关 : refresh cache Too many requests have been sent to server

Question

我猜我调用 AWS Storage Gateway refreshCache 方法的频率太高了(如消息所示)，但我不确定我需要等多久才能再次点击它，我们将不胜感激。

AWSStorageGateway gatewayClient = AWSStorageGatewayClientBuilder.standard().build();
 RefreshCacheRequest cacheRequest = new RefreshCacheRequest();
 cacheRequest.setFileShareARN(this.fileShareArn);
 gatewayClient.refreshCache(cacheRequest);

com.amazonaws.services.storagegateway.model.InvalidGatewayRequestException:已向服务器发送了太多请求。 (服务:AWSStorageGateway；状态代码:400；错误代码:InvalidGatewayRequestException；请求 ID:f1ffa249-6908-4ae1-9f71-93fe7f26b2af)在 com.amazonaws.http.AmazonHttpClient$RequestExecutor.handleErrorResponse(AmazonHttpClient.java:1712)在 com.amazonaws.http.AmazonHttpClient$RequestExecutor.executeOneRequest(AmazonHttpClient.java:1367)在 com.amazonaws.http.AmazonHttpClient$RequestExecutor.executeHelper(AmazonHttpClient.java:1113)在 com.amazonaws.http.AmazonHttpClient$RequestExecutor.doExecute(AmazonHttpClient.java:770)

我想你可以引用官方文档。 https://docs.aws.amazon.com/storagegateway/latest/APIReference/API_RefreshCache.html

正如它所说，

When this API is called, it only initiates the refresh operation. When the API call completes and returns a success code, it doesn't necessarily mean that the file refresh has completed. You should use the refresh-complete notification to determine that the operation has completed before you check for new files on the gateway file share.

所以我猜想在您调用 AWS Storage Gateway refreshCache 方法之后，您必须等到刷新操作完成。如果在此期间再次调用该方法，则会引发一些异常。

解决方法可以引用Monitoring Your File Share设置通知。
