Create a Google Cloud Storage Bucket

Demonstrates how to create a Google Cloud Storage bucket. Lua

local chilkat = require("chilkat")

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

-- This example uses a previously obtained access token having permission for the
-- scope "https://www.googleapis.com/auth/cloud-platform"

-- In this example, Get Google Cloud Storage OAuth2 Access Token,
-- the service account access token was saved to a text file.  This example fetches the access token from the file..
local sbToken = chilkat.StringBuilder.new()
sbToken:load_file("qa_data/tokens/googleCloudStorageAccessToken.txt", "utf-8")

-- ---- Step 1
-- Create a JSON that contains the following information, replacing [VALUES_IN_BRACKETS] with the appropriate values:

-- {
--   "name": "[BUCKET_NAME]",
--   "location": "[BUCKET_LOCATION]",
--   "storageClass": "[STORAGE_CLASS]"
-- }

local json = chilkat.JsonObject.new()
json:update_string("name", "chilkat-ocean")
json:update_string("location", "us")
json:update_string("storageClass", "multi_regional")

-- ---- Step 2
-- Send a POST equivalent to this curl command

-- curl -X POST --data-binary @[JSON_FILE_NAME].json \
--      -H "Authorization: Bearer [OAUTH2_TOKEN]" \
--      -H "Content-Type: application/json" \
--      "https://www.googleapis.com/storage/v1/b?project=[PROJECT_ID]"

local http = chilkat.Http.new()
http.auth_token = sbToken:get_as_string()

http:set_url_var("project_id", "chilkat-176611")
local url = "https://www.googleapis.com/storage/v1/b?project={$project_id}"
local resp = chilkat.HttpResponse.new()
local success = http:http_json("POST", url, json, "application/json", resp)
if not success then
    print(http.last_error_text)
    return
end

local responseCode = resp.status_code
if responseCode == 401 then
    print(resp.body_str)
    print("If invalid credentials, then it is likely the access token expired.")
    print("Your app should automatically fetch a new access token and re-try.")
    return
end

print("Response code: " .. responseCode)
print("Response body")
print(resp.body_str)

-- A successful response looks like this:
-- Response code: 200
-- Response body
-- {
--  "kind": "storage#bucket",
--  "id": "chilkat-ocean",
--  "selfLink": "https://www.googleapis.com/storage/v1/b/chilkat-ocean",

-- Parse the JSON response:
local jsonResp = chilkat.JsonObject.new()
jsonResp:load(resp.body_str)

print("name: " .. jsonResp:string_of("name"))
print("timeCreated: " .. jsonResp:string_of("timeCreated"))

-- Parse the date/time created.
local dt = chilkat.DateTime.new()
dt:set_from_timestamp(jsonResp:string_of("timeCreated"))
-- ...
