(Chilkat2-Python) Upload String to Google Cloud Storage

Demonstrates how to upload an in-memory string to Google Cloud Storage.

Note: This example requires Chilkat v9.5.0.69 or later because it uses the http.PTextSb method.

Chilkat2 Python Downloads

install with pip

pip3 install chilkat2

or download... Python Module for Windows, Linux, Alpine Linux, MacOS, Solaris

import sys
import chilkat2

# 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 = chilkat2.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 = 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>
# </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
# resp is a CkHttpResponse
resp = http.PTextSb("POST",url,sbXml,"utf-8","application/xml",False,False)
if (http.LastMethodSuccess == False):
    print(http.LastErrorText)
    sys.exit()

responseCode = resp.StatusCode
if (responseCode == 401):
    print(resp.BodyStr)
    print("If invalid credentials, then it is likely the access token expired.")
    print("Your app should automatically fetch a new access token and re-try.")

    sys.exit()

print("Response code: " + str(responseCode))
print("Response body")
print(resp.BodyStr)

# A successful response looks like this:
# Response code: 200
