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

// 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..
Chilkat.StringBuilder sbToken = new 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]"

Chilkat.Http http = new Chilkat.Http();
http.AuthToken = sbToken.GetAsString();

// Create an XML document, and write it to a StringBuilder.
// We'll be uploading this XML document.
Chilkat.Xml xml = new 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.
Chilkat.StringBuilder sbXml = new 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");
string 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
Chilkat.HttpResponse resp = http.PTextSb("POST",url,sbXml,"utf-8","application/xml",false,false);
if (http.LastMethodSuccess == false) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

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

    return;
}

Debug.WriteLine("Response code: " + Convert.ToString(responseCode));
Debug.WriteLine("Response body");
Debug.WriteLine(resp.BodyStr);

// A successful response looks like this:
