* 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..
loSbToken = CreateObject('Chilkat.StringBuilder')
loSbToken.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.
