AWS S3 Java: doesObjectExist results in 403: FORBIDDEN

Question

I\'m having trouble with my Java program using the AWS SDK to interact with an S3 bucket.

This is the code I use to create an S3 client:

public S3Sto         


        

Answer 1

Your credentials may be correct, but you will still get FORBIDDEN if you do not set the correct IAM polices. To check for objects in s3 you need the following:

{
    "Version":"2012-10-17",
    "Statement":[
        {
            "Effect":"Allow",
            "Action":[
            "s3:ListBucket"
            ],
            "Resource":["arn:aws:s3:::examplebucket/*"]
        },
        {
            "Effect":"Allow",
            "Action":[
            "s3:GetObject"
            ],
          "Resource":["arn:aws:s3:::examplebucket/*"]
        }
    ]
}
