I am trying to find an efficient way to check whether a bucket exist in aws S3 service. I don't want to use the list bucket function of s3 go sdk 'listBuckets' I tried using 'headBucket' function but I think i am using it in the wrong way. any help would be appreciated!

douzai9405 2018-12-18 12:44关注headBucket is the right method if it is your bucket. This way you can check if the bucket exists.
If you mean globally I would try to create the bucket with a uuid at the end. If the bucket already exists you will get the error:
ErrCodeBucketAlreadyExists "BucketAlreadyExists".Does this help?
