在boto3中,您可以使用S3.Client.head_object()方法仅加载单个键的元数据。
awsRegion = 'ap-south-1' client = boto3.client('S3', aws_access_key_id=key_id, aws_secret_access_key=secret, region_name=awsRegion) # get img from s3 def load_s3(bucket, key): logger.info('load from s3://{bucket}/{key}') try: response = client.get_object( Bucket=bucket, ...
Using the AWS SDK, you can send a HEAD request, which will tell you if a file exists atKey. Seehttp://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/S3.html#headObject-property varclient=require('s3').createClient({/* options */});client.s3.headObject({Bucket:'s3 bucket name',Key...

S3Client s3 = S3Client.builder().region(Region.US_WEST_2).build(); 操作S3存储桶创建了S3客户端之后,你可以对S3存储桶进行各种操作,例如列出所有存储桶、创建新的存储桶、删除存储桶、获取存储桶的属性等。以下是一些示例:列出所有存储桶: ListBucketResult listResult = s3.listBuckets(); listResult.bucket...
When the user does not have the S3:GetObject permission, S3Client's doesObjectExist method always returns false. It should throw an access denied exception, and only return true or false if it is absolutely sure that the object does or does not exist. Thank you!
