# 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..
sbToken = Chilkat::CkStringBuilder.new()
sbToken.LoadFile("qa_data/tokens/googleCloudStorageAccessToken.txt","utf-8")

# Send a POST equivalent to this curl command.
# The content of the file is contained in the request body.

# curl -X POST --data-binary @[OBJECT] \
#     -H "Authorization: Bearer [OAUTH2_TOKEN]" \
#     -H "Content-Type: [OBJECT_CONTENT_TYPE]" \
#     "https://www.googleapis.com/upload/storage/v1/b/[BUCKET_NAME]/o?uploadType=media&name=[OBJECT_NAME]"

# Use %20 for the SPACE chars in the path.

# Indicate the file to be streamed in the request body when the HTTP POST is sent.
# Use SPACE chars directly in the local file path.
