下载文件的方法与上传非常相似,我们只需调用指定的接口进行下载。 importcom.amazonaws.services.s3.model.S3Object;importjava.io.FileOutputStream;importjava.io.InputStream;publicclassS3Downloader{privateAmazonS3s3Client;publicS3Downloader(AmazonS3s3Client){this.s3Client=s3Client;}publicvoiddownloadFile(Stringbuck...

如果要从S3存储桶下载数据到Lambda函数中,可以使用download_file方法:s3_client.download_file(bucket_name, s3_file_key, local_file_path)。其中,bucket_name是源存储桶的名称,s3_file_key是要下载的文件在存储桶中的键,local_file_path是下载文件保存到本地的路径。 使用boto3进行S3同步的优势包括: 简单易用...
