#  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.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]"
