Amazon Glacier Set Vault Access Policy

See more Amazon Glacier Examples

Demonstrates how to set an access policy for a vault (will overwrite the existing policy). Lua

local chilkat = require("chilkat")

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

local rest = chilkat.Rest.new()

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

-- Provide AWS credentials.
local authAws = chilkat.AuthAws.new()
authAws.access_key = "AWS_ACCESS_KEY"
authAws.secret_key = "AWS_SECRET_KEY"
authAws.service_name = "glacier"

success = rest:set_auth_aws(authAws)

-- --------------------------------------------------------------------------
-- Note: The above REST connection and setup of the AWS credentials
-- can be done once.  After connecting, any number of REST calls can be made.
-- The "auto reconnect" property passed to rest.Connect indicates that if
-- the connection is lost, a REST method call will automatically reconnect
-- if needed.
