S3 - Working with Buckets in a Region

See more Amazon S3 (new) Examples

Demonstrates how to work with S3 buckets located in a particular region. Lua

local chilkat = require("chilkat")

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

-- When usig the REST class to access an S3 bucket that has been created in a particular region,
-- there are three important things to remember:
--
-- 1) Connect to the domain that includes the region.  For example, instead of connecting to
--    "s3.amazonaws.com", connect to "s3.eu-central-1.amazonaws.com" if your bucket is in the EU Frankfurt region.
--    See http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region   for a list of S3 region domains (endpoints)
--
-- 2) Set the AuthAws.Region property equal to the region, such as "eu-central-1".
--
-- 3) Include the region in request's Host header.
--

-- This example will upload to a bucket in the eu-central-1 region.
--
local rest = chilkat.Rest.new()

-- Connect to the Amazon AWS REST server.
local bTls = true
local port = 443
local bAutoReconnect = true
local success = rest:connect("s3.eu-central-1.amazonaws.com", port, bTls, bAutoReconnect)

-- Provide AWS credentials for the REST call.
local authAws = chilkat.AuthAws.new()
authAws.access_key = "AWS_ACCESS_KEY"
authAws.secret_key = "AWS_SECRET_KEY"
authAws.service_name = "s3"
authAws.region = "eu-central-1"
success = rest:set_auth_aws(authAws)

-- Set the bucket name via the HOST header.
-- In this case, the bucket name is "chilkateufrankfurt" (which was created in the eu-central-1 region)
rest.host = "chilkateufrankfurt.s3.eu-central-1.amazonaws.com"

local fileData = chilkat.BinData.new()
success = fileData:load_file("qa_data/jpg/starfish.jpg")

-- Upload the file to Amazon S3.
local responseBody = chilkat.StringBuilder.new()
success = rest:full_request_bd("PUT", "/starfish.jpg", fileData, responseBody)
if not success then
    print(rest.last_error_text)
    return
end

-- Did we get a 200 response indicating success?
local statusCode = rest.response_status_code
if statusCode ~= 200 then
    print("Error response: " .. responseBody:get_as_string())
    print("Status code: " .. statusCode .. ", Status text: " .. rest.response_status_text)
    return
end

print("File successfully uploaded.")
