(PHP ActiveX) Upload In-Memory Binary Data to Google Cloud Storage

Demonstrates how to upload in-memory binary data to Google Cloud Storage.

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

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

// 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..
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder')
$sbToken = new COM("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]"

// a Google Storage bucket.
