Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require 'chilkat'

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

http = Chilkat::CkHttp.new()

# Insert your AWS keys here:
http.put_AwsAccessKey("AWS_ACCESS_KEY")
http.put_AwsSecretKey("AWS_SECRET_KEY")

bucketName = "chilkat.ocean"
objectName = "seahorse.jpg"
localFilePath = "qa_data/jpg/seahorse.jpg"
contentType = "image/jpg"

# User-defined metadata are name/value pairs, and are added to the HTTP request header.
# Header names must begin with "x-amz-meta-" to distinguish them from other HTTP headers.
# Note that Amazon S3 stores user-defined metadata keys in lowercase.

# For example, to add genus=Hippocampus, we do this:
http.SetRequestHeader("x-amz-meta-genus","Hippocampus")

# Add a few more user-metadata key pairs.
http.SetRequestHeader("x-amz-meta-species","big-belly seahorse")
http.SetRequestHeader("x-amz-meta-habitat","shallow tropical and temperate waters")

success = http.S3_UploadFile(localFilePath,contentType,bucketName,objectName)

if (success != true)
    print http.lastErrorText() + "\n";
else
    print "File uploaded." + "\n";
