Azure Storage Blob Service REST API: Sample code to get the permissions of a container. Lua

local chilkat = require("chilkat")

-- Azure Blob Service Example: Get Container ACL
-- See also: https://msdn.microsoft.com/en-us/library/azure/dd179469.aspx

-- 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 Azure Storage Blob Service
local bTls = true
local port = 443
local bAutoReconnect = true
-- In this example, the storage account name is "chilkat".
local success = rest:connect("chilkat.blob.core.windows.net", port, bTls, bAutoReconnect)
if not success then
    print(rest.last_error_text)
    return
end

-- Provide Azure Cloud credentials for the REST call.
local azAuth = chilkat.AuthAzureStorage.new()
azAuth.access_key = "AZURE_ACCESS_KEY"
-- The account name used here should match the 1st part of the domain passed in the call to Connect (above).
azAuth.account = "chilkat"
azAuth.scheme = "SharedKey"
azAuth.service = "Blob"
-- This causes the "x-ms-version: 2021-08-06" header to be automatically added.
azAuth.xms_version = "2021-08-06"
success = rest:set_auth_azure_storage(azAuth)

-- Note: The application does not need to explicitly set the following
-- headers: x-ms-date, Authorization.  These headers
-- are automatically set by Chilkat.

-- The expected success response is a 200 response status code with an XML response body.
-- In this example, we are getting the ACL permissions of the container named "mycontainer".
local responseStr = rest:full_request_no_body("GET", "/mycontainer?restype=container&comp=acl")
if not rest.last_method_success then
    print(rest.last_error_text)
    return
end

-- When successful, the Azure Storage service will respond with a 200 response status code,
-- with an XML response body.

if rest.response_status_code ~= 200 then
    -- Examine the request/response to see what happened.
    print("response status code = " .. rest.response_status_code)
    print("response status text = " .. rest.response_status_text)
    print("response header: " .. rest.response_header)
    print("response body (if any): " .. responseStr)
    print("---")
    print("LastRequestStartLine: " .. rest.last_request_start_line)
    print("LastRequestHeader: " .. rest.last_request_header)
    return
end

-- Load the XML response for parsing.
-- An example of the response XML is shown below.
local xml = chilkat.Xml.new()
success = xml:load_xml(responseStr)

print(xml:get_xml())

-- Use the ChilkatPath method to get various pieces of information out
-- of the XML.  For example:

print("Id = " .. xml:chilkat_path("SignedIdentifier|Id|*"))
local startTimeStr = xml:chilkat_path("SignedIdentifier|AccessPolicy|Start|*")
print("Start Time = " .. startTimeStr)

-- The date/time string can be loaded into a CkDateTime object for
-- access to individual parts, or conversion to other formats.
local dateTime = chilkat.DateTime.new()
success = dateTime:set_from_timestamp(startTimeStr)

-- For example..
local bLocalTime = true
local dt = chilkat.DtObj.new()
dateTime:to_dt_obj(bLocalTime, dt)

print(dt.year .. "/" .. dt.month .. "/" .. dt.day)
