Demonstrates how to create a Google Cloud Storage bucket. VB.NET

Dim success As Boolean = False

' 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..
Dim sbToken As New Chilkat.StringBuilder

' ---- 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]"
' }

Dim json As New Chilkat.JsonObject
json.UpdateString("name","chilkat-ocean")
json.UpdateString("location","us")
json.UpdateString("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]"
