<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

// 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 CkStringBuilder();
$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 CkHttp();
$http->put_AuthToken($sbToken->getAsString());

// Create an XML document, and write it to a StringBuilder.
// We'll be uploading this XML document.
$xml = new CkXml();
$xml->put_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 CkStringBuilder();
$xml->GetXmlSb($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->get_LastMethodSuccess() == false) {
    print $http->lastErrorText() . "\n";
    exit;
}

$responseCode = $resp->get_StatusCode();
if ($responseCode == 401) {
    print $resp->bodyStr() . "\n";
    print 'If invalid credentials, then it is likely the access token expired.' . "\n";
    print 'Your app should automatically fetch a new access token and re-try.' . "\n";

    exit;
}

print 'Response code: ' . $responseCode . "\n";
print 'Response body' . "\n";
print $resp->bodyStr() . "\n";
