S3 - Working with Buckets in a Region

See more Amazon S3 (new) Examples

Demonstrates how to work with S3 buckets located in a particular region. Rust

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

// When usig the REST class to access an S3 bucket that has been created in a particular region,
// there are three important things to remember:
// 
// 1) Connect to the domain that includes the region.  For example, instead of connecting to
//    "s3.amazonaws.com", connect to "s3.eu-central-1.amazonaws.com" if your bucket is in the EU Frankfurt region.
//    See http://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region   for a list of S3 region domains (endpoints)
// 
// 2) Set the AuthAws.Region property equal to the region, such as "eu-central-1".
// 
// 3) Include the region in request's Host header.
// 

// This example will upload to a bucket in the eu-central-1 region.
// 
let rest = chilkat::Rest::new();

// Connect to the Amazon AWS REST server.
let b_tls = true;
let port = 443;
let b_auto_reconnect = true;
let _ = rest.connect("s3.eu-central-1.amazonaws.com", port, b_tls, b_auto_reconnect).is_ok();

// Provide AWS credentials for the REST call.
let auth_aws = chilkat::AuthAws::new();
auth_aws.set_access_key("AWS_ACCESS_KEY");
auth_aws.set_secret_key("AWS_SECRET_KEY");
auth_aws.set_service_name("s3");
auth_aws.set_region("eu-central-1");
let _ = rest.set_auth_aws(&auth_aws).is_ok();

// Set the bucket name via the HOST header.
// In this case, the bucket name is "chilkateufrankfurt" (which was created in the eu-central-1 region)
rest.set_host("chilkateufrankfurt.s3.eu-central-1.amazonaws.com");

let file_data = chilkat::BinData::new();
let _ = file_data.load_file("qa_data/jpg/starfish.jpg").is_ok();

// Upload the file to Amazon S3.
let response_body = chilkat::StringBuilder::new();
if rest.full_request_bd("PUT", "/starfish.jpg", &file_data, &response_body).is_err() {
    println!("{}", rest.last_error_text());
    return;
}

// Did we get a 200 response indicating success?
let status_code = rest.response_status_code();
if status_code != 200 {
    println!("Error response: {}", response_body.get_as_string().unwrap_or_default());
    println!("Status code: {}, Status text: {}", status_code, rest.response_status_text());
    return;
}

println!("File successfully uploaded.");
