S3 Rename File

See more Amazon S3 (new) Examples

Demonstrates how to rename a file on Amazon S3.

Renaming an object (file) in AWS S3 using the AWS S3 API involves copying the object to a new location with the desired name and then deleting the original object.

Ruby

require 'chilkat'

success = false

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

rest = Chilkat::CkRest.new()

# Connect to the Amazon AWS REST server in the desired region.
bTls = true
port = 443
bAutoReconnect = true
success = rest.Connect("s3-us-west-2.amazonaws.com",port,bTls,bAutoReconnect)

# Provide AWS credentials.
authAws = Chilkat::CkAuthAws.new()
authAws.put_AccessKey("AWS_ACCESS_KEY")
authAws.put_SecretKey("AWS_SECRET_KEY")
authAws.put_ServiceName("s3")

# This particular bucket is in the Oregon region, as opposed to the US Standard,
# therefore the Region must be set appropriately.
# Also note that we connected to "s3-us-west-2.amazonaws.com".
authAws.put_Region("us-west-2")

rest.SetAuthAws(authAws)

# Set the bucket name via the HOST header.
# In this case, the bucket name is "chilkat.qa".
# Note that the Host header should use "bucketName.s3.amazonaws.com", not "bucketName.s3-us-west-2.amazonaws.com"
rest.put_Host("chilkat.qa.s3.amazonaws.com")

# Copy /images/sea_creatures/starfish.jpg to /images/sea_creatures/starfish3.jpg
# Notice here that the x-amz-copy-source includes the bucket in the source path,
# but the target path passed to FullRequestNoBody does NOT contain the bucket (because the bucket
# was already specified in the Host header).
rest.AddHeader("x-amz-copy-source","/chilkat.qa/images/sea_creatures/starfish.jpg")

sbResponse = Chilkat::CkStringBuilder.new()
success = rest.FullRequestNoBodySb("PUT","/images/sea_creatures/starfish3.jpg",sbResponse)
if (success == false)
    print rest.lastErrorText() + "\n";
    exit
end

# When successful, the S3 Storage service will respond with a 200 or 204 response code,
# with an XML body.  
if (rest.get_ResponseStatusCode() != 200)
    # Examine the request/response to see what happened.
    print "response status code = " + rest.get_ResponseStatusCode().to_s() + "\n";
    print "response status text = " + rest.responseStatusText() + "\n";

print "Copy Successful." + "\n";

# --------------------------------------
# Now we can delete the original file..
# --------------------------------------

# We no longer want to send the x-amz-copy-source header.  Remove it.
rest.RemoveHeader("x-amz-copy-source")

success = rest.FullRequestNoBodySb("DELETE","/images/sea_creatures/starfish.jpg",sbResponse)
if (success == false)
    print rest.lastErrorText() + "\n";
    exit
end

# If successfully deleted, the response status code is 204 and the response body text will be empty.
