# 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 = chilkat2.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 = chilkat2.Http()
http.AuthToken = sbToken.GetAsString()

# Create an XML document, and write it to a StringBuilder.
# We'll be uploading this XML document.

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 = chilkat2.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>

# resp is a CkHttpResponse
