Google Cloud SQL - Get Instance Information

See more Google Cloud SQL Examples

Demonstrates how to get information about your Cloud SQL instances, including instance summary information, usage data, operation logs, and database logs. Lua

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

-- In this example, Get Google Cloud SQL 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()

-- Implements the following CURL command:

-- curl -X GET \
-- -H "Authorization: Bearer access-token" \
-- https://www.googleapis.com/sql/v1beta4/projects/project-id/instances/instance-id

-- Use the following online tool to generate HTTP code from a CURL command
-- Convert a cURL Command to HTTP Source Code

-- Causes the "Authorization: Bearer "$(gcloud auth print-access-token)" header to be added.
http.auth_token = sbToken:get_as_string()

-- Replace "project-id" with your actual Google project ID.
-- Replace "instance-id" with your database instance ID, which is the name of your database.  (For example, when I created my test database I named it "chilkat", and therefore my instance-id is "chilkat".)
