Rust Requires Chilkat v11.0.0+

Upload In-Memory Binary Data to Google Cloud Storage

See more Google Cloud Storage Examples

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

// 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..
let sb_token = chilkat::StringBuilder::new();
let _ = sb_token.load_file("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]"

// Download a JPG image from the Internet, and then upload this JPG to
// a Google Storage bucket.

let jpg_data = chilkat::BinData::new();

    println!("{}", http.last_error_text());

http.set_auth_token(&sb_token.get_as_string().unwrap_or_default());

// Construct a URL to upload to an object named "starfish.jpg" in the "chilkat-ocean" bucket.
