// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Http')
$http = new COM("Chilkat.Http");

// Implements the following CURL command:

// curl -X PATCH --data-binary @JSON_FILE_NAME \
//   -H "Authorization: Bearer OAUTH2_TOKEN" \
//   -H "Content-Type: application/json" \
//   "https://storage.googleapis.com/storage/v1/b/BUCKET_NAME/o/OBJECT_NAME"

// Use the following online tool to generate HTTP code from a CURL command
// Convert a cURL Command to HTTP Source Code

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.BinData')
$bdRequestBody = new COM("Chilkat.BinData");
$success = $bdRequestBody->LoadFile('JSON_FILE_PATH');
if ($success != 1) {
    print 'Failed to load JSON_FILE_PATH' . "\n";
    exit;
}

// Adds the "Authorization: Bearer OAUTH2_TOKEN" header.
$http->AuthToken = 'OAUTH2_TOKEN';

// resp is a Chilkat.HttpResponse
$resp = $http->PBinaryBd('PATCH','https://storage.googleapis.com/storage/v1/b/BUCKET_NAME/o/OBJECT_NAME',$bdRequestBody,'application/json',0,0);
if ($http->LastMethodSuccess == 0) {
    print $http->LastErrorText . "\n";
    exit;
}

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder')
$sbResponseBody = new COM("Chilkat.StringBuilder");
$resp->GetBodySb($sbResponseBody);

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JsonObject')
$jResp = new COM("Chilkat.JsonObject");
$jResp->LoadSb($sbResponseBody);
$jResp->EmitCompact = 0;

print 'Response Body:' . "\n";
print $jResp->emit() . "\n";
