# 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 the JSON body of the PUT request that will be sent.

# {
#   "storageClass": "[STORAGE_CLASS]"
# }
# 

$json = New-Object Chilkat.JsonObject
# Be careful if using the "regional" storage class.  See the note below about the 400 error response.
$json.UpdateString("storageClass","nearline")

# ---- Step 2
# Send a PUT equivalent to this curl command

# curl -X PUT --data-binary @[JSON_FILE_NAME].json \
#     -H "Authorization: Bearer [OAUTH2_TOKEN]" \
#     -H "Content-Type: application/json" \
#     "https://www.googleapis.com/storage/v1/b/[BUCKET_NAME]?fields=storageClass"
