Upload File to Google Cloud Storage

See more Google Cloud Storage Examples

Demonstrates how to upload a file 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"

let json_token = chilkat::JsonObject::new();
if json_token.load_file("qa_data/tokens/googleCloudStorage.json").is_err() {
    println!("{}", json_token.last_error_text());
    return;
}

// 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]"

let req = chilkat::HttpRequest::new();
req.set_http_verb("POST");
req.set_path(&sb_path.get_as_string().unwrap_or_default());
req.set_content_type("image/jpeg");
// Indicate the file to be streamed in the request body when the HTTP POST is sent.
let _ = req.stream_body_from_file("qa_data/jpg/penguins.jpg");
