Riak CS SetBucketPolicy

[IvanLuber]

Hi,
I've been using golang with minio-go client (https://github.com/minio/minio-go) to Put and Get image objects to RiakCS, and it works splendidly.
But problem arised (I got Accessdenied error) when the object is accessed with url through browser hostname/bucketname/objectkey
*the object is put directly under the bucket

I've raised issue to minio-go (minio/minio-go#894) and it's pointed out to me that Riak CS needs to implement SetBucketPolicy API Handler. It's Probably because Bucket ACL's are deprecated and instead Bucket policies are implemented as in http://docs.aws.amazon.com/AmazonS3/latest/user-guide/add-bucket-policy.html

I hope you can help me with this problem, Best Regards ~

As I did that work for sure ( #364 ), I think you may have misconfigured something either on the CS or on client side.

Hi, @kuenishi , maintainer from minio-go, @poornas , has been actively helping me to solve this issue.
it was pointed out to me that when minio-go client send API request to set a bucket policy :

---------START-HTTP---------

It is not sending content-type as a compliance with s3 spec . maybe Riak is expecting content-type header and throwing an error ?
