'  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..
set sbToken = Server.CreateObject("Chilkat_9_5_0.StringBuilder")
success = 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]"

set http = Server.CreateObject("Chilkat_9_5_0.Http")
http.AuthToken = sbToken.GetAsString()

'  Create an XML document, and write it to a StringBuilder.
'  We'll be uploading this XML document.
set xml = Server.CreateObject("Chilkat_9_5_0.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.
set sbXml = Server.CreateObject("Chilkat_9_5_0.StringBuilder")
success = 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.

success = http.SetUrlVar("object_name","test.xml")

'  Note: The PTextSb method first appears in Chilkat v9.5.0.69
' resp is a Chilkat_9_5_0.HttpResponse
Set resp = http.PTextSb("POST",url,sbXml,"utf-8","application/xml",0,0)
If (http.LastMethodSuccess = 0) Then

    Response.End
End If
