Amazon S3 - Create Bucket with Constraint

Create an Amazon S3 bucket with a constraint using the REST API.

Download Chilkat Ruby Library

#  <CreateBucketConfiguration>
#          <LocationConstraint>EU</LocationConstraint>
#  </CreateBucketConfiguration>

#  The HTTP component now includes a method to generate
#  the current date/time in RFC 2616 compliant format.
#  Note: The GenTimeStamp method is available as a pre-release (as of 18-June-2008).
#  It will become available in the next new version dated after
#  18-June-2008.

#  The PUT request operation with a bucket URI creates a new bucket.

#  We want SHA1 for the HMAC hash algorithm:
crypt.put_HashAlgorithm("sha1")

#  These must be changed for your account:
AWSAccessKeyId = "zzzzzzzzzzzzzzzzzzzz"
AWSSecretAccessKey = "zzzzzzzzzzzzzzzzzzzzzzzzzz"

#  Set the HMAC secret key:
crypt.SetHmacKeyString(AWSSecretAccessKey)

#  By setting the charset = "utf-8", the string will be converted
#  to utf-8 (internal to the Chilkat component) prior to signing:
crypt.put_Charset("utf-8")

#  Indicate that Base64 output is desired:
crypt.put_EncodingMode("base64")

signature = crypt.hmacStringENC(strToSign)

#  The bucket to be created is specified in the Host header.
#  In this example, the "chilkat2" bucket is created:
