//  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..

//  ---- 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]"
//  }

//  ---- 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" \
