More specifically, the code that it delegates to in com.amazonaws.services.s3.internal.ServiceUtils.retryableDownloadS3ObjectToFile is flawed. Here are the problems I've identified in the methods for downloading S3 objects to disk: The r...
Retrieves an object from Amazon S3. In theGetObjectrequest, specify the full key name for the object. General purpose buckets- Both the virtual-hosted-style requests and the path-style requests are supported. For a virtual hosted-style request example, if you have the objectphotos/2006/February...

要列出 AWS S3 存储桶中的对象,我们需要创建一个ListObjectsV2Request实例并指定存储桶名称。然后,我们在 s3Client 对象上调用 listObjectsV2方法,并将请求作为参数传递。此方法返回一个ListObjectsV2Response,其中包含有关存储桶中对象的信息。 6.3. 下载对象 要下载对象,我们首先创建一个GetObjectRequest实例并将存储桶名...
内置机制(用于整个AWS SDK)不能处理的是读取S3对象数据。 如果调用AmazonS3.getObject (GetObjectRequest getObjectRequest, File destinationFile),AmazonS3Client将使用自己的重试机制。该机制位于ServiceUtils.retryableDownloadS3ObjectToFile (source)内部,它使用一种次优的硬连接重试行为(它只会重试一次,而不会在Socket...
