Upload Filename with SPACE Chars to Google Cloud Storage

See more Google Cloud Storage Examples

Demonstrates how to upload a file with SPACE chars in the name 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]"

let http = chilkat::Http::new();
http.set_auth_token(&sb_token.get_as_string().unwrap_or_default());

// Use %20 for the SPACE chars in the path.
let sb_path = chilkat::StringBuilder::new();
let _ = sb_path.append("/upload/storage/v1/b/bucket_name/o?uploadType=media&name=file%20with%20space%20char.jpg");
let num_replaced = sb_path.replace("bucket_name", "chilkat-ocean");

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.
// Use SPACE chars directly in the local file path.
let _ = req.stream_body_from_file("qa_data/jpg/file with space char.jpg");

let resp = chilkat::HttpResponse::new();
if http.http_s_req("www.googleapis.com", 443, true, &req, &resp).is_err() {
    println!("{}", http.last_error_text());
    return;
}

let response_code = resp.status_code();
if response_code == 401 {
    println!("{}", resp.body_str());
    println!("If invalid credentials, then it is likely the access token expired.");
    println!("Your app should automatically fetch a new access token and re-try.");
    return;
}

println!("Response code: {}", response_code);
println!("Response body");
println!("{}", resp.body_str());
