(JavaScript) Google Cloud SQL - Start Database Instance

Demonstrates how to start a Google Cloud SQL database instance.

For more information, see https://cloud.google.com/sql/docs/mysql/start-stop-restart-instance

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

// 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..
var sbToken = new CkStringBuilder();
sbToken.LoadFile("qa_data/tokens/google_cloud_sql_access_token.txt","utf-8");

// Implements the following CURL command:

// curl -X PATCH \
// -H "Authorization: Bearer "$(gcloud auth print-access-token) \
// -H "Content-Type: application/json; charset=utf-8" \
// -d '{
//   "settings": {
//     "activationPolicy": "ALWAYS" 
//   }
// }' \

// The following JSON is sent in the request body.

// {
//   "settings": {

//   }
// }

// Use "ALWAYS" to start an instance.  Use "NEVER" to stop an instance.

// Causes the "Authorization: Bearer "$(gcloud auth print-access-token)" header to be added.
