* 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..
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbToken = CreateObject('Chilkat.StringBuilder')
loSbToken.LoadFile("qa_data/tokens/google_cloud_sql_access_token.txt","utf-8")

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Http')
loHttp = CreateObject('Chilkat.Http')

* 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" 
*   }
* }' \
* https://www.googleapis.com/sql/v1beta4/projects/project-id/instances/instance-id

* Use this online tool to generate code from sample JSON:
* Generate Code to Create JSON

* The following JSON is sent in the request body.

* {
*   "settings": {
*     "activationPolicy": "ALWAYS"
*   }
* }

* Use "ALWAYS" to start an instance.  Use "NEVER" to stop an instance.
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJson = CreateObject('Chilkat.JsonObject')
loJson.UpdateString("settings.activationPolicy","ALWAYS")

* Causes the "Authorization: Bearer "$(gcloud auth print-access-token)" header to be added.
loHttp.AuthToken = loSbToken.GetAsString()

loHttp.SetRequestHeader("Content-Type","application/json; charset=utf-8")

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.StringBuilder')
loSbRequestBody = CreateObject('Chilkat.StringBuilder')
loJson.EmitSb(loSbRequestBody)

* 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".)
