fix: getBucketLocation using virtual hosted style for Ksyun KS3

[ChaosBee]

Ksyun KS3 —— Object Storage Service by Kingsoft Cloud.

The getBucketLocation API is accessed using virtual hosted style in KS3 by default.

We are not going to add more endpoints here. Aliyun is where we will stop.

OK. Thank you for your response.
What a pity. I believe that host-style access is better than path-style access. So is it possible that minio-sdk or minio will add a variable changing the style of get-bucket-location?

All you need to do is tell how the bucket lookups must happen

https://github.com/minio/minio-go/blob/master/api.go#LL107C6-L107C6

There is no reason to have new magic added into codebase. However I would perhaps go ahead and allow extending the checks to ensure users pass their own functions here instead of polluting the SDK further.

As your mention, I tried the BucketLoookup Variable before, but it does no effect on the urlStr that get_bucket_location use.

Yes that is correct because an S3 service must implement both path and dns style. The region is not known prior to getBucketLocation() - however can fix the behavior here. to use DNS style for GetBucketLocation() requests if it works?

#1785 this should work for you @ChaosBee
