# 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 = New-Object Chilkat.StringBuilder
$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]"

$http = New-Object Chilkat.Http
$http.AuthToken = $sbToken.GetAsString()

# Create an XML document, and write it to a StringBuilder.
# We'll be uploading this XML document.
$xml = New-Object Chilkat.Xml
$xml.Tag = "note"
$xml.UpdateChildContent("to","Tove")
$xml.UpdateChildContent("from","Jani")
$xml.UpdateChildContent("heading","Reminder")
$xml.UpdateChildContent("body","Don't forget me this weekend!")

# Write the XML to sbXml.
$sbXml = New-Object Chilkat.StringBuilder
$xml.GetXmlSb($sbXml)

# sbXml contains this:

# <note>
#     <to>Tove</to>
#     <from>Jani</from>
#     <heading>Reminder</heading>
#     <body>Don't forget me this weekend!</body>
# </note>

# Construct a URL to upload to an object named "test.xml" in the "chilkat-ocean" bucket.
$http.SetUrlVar("bucket_name","chilkat-ocean")
$http.SetUrlVar("object_name","test.xml")
$url = "https://www.googleapis.com/upload/storage/v1/b/{$bucket_name}/o?uploadType=media&name={$object_name}"

# Note: The PTextSb method first appears in Chilkat v9.5.0.69
