Amazon Glacier Get Vault Access Policy

See more Amazon Glacier Examples

Demonstrates how to retrieve the access-policy subresource set on the vault Rust

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

let rest = chilkat::Rest::new();

// Connect to the Amazon AWS REST server in the desired region.
let b_tls = true;
let port = 443;
let b_auto_reconnect = true;
let _ = rest.connect("glacier.us-west-2.amazonaws.com", port, b_tls, b_auto_reconnect).is_ok();

// Provide AWS credentials.
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("glacier");
auth_aws.set_region("us-west-2");

let _ = rest.set_auth_aws(&auth_aws).is_ok();

// --------------------------------------------------------------------------
// Note: The above REST connection and setup of the AWS credentials
// can be done once.  After connecting, any number of REST calls can be made.
// The "auto reconnect" property passed to rest.Connect indicates that if
// the connection is lost, a REST method call will automatically reconnect
// if needed.
// --------------------------------------------------------------------------

// For more information, see Glacier Get Vault Access Policy Reference Documentation

let _ = rest.add_header("x-amz-glacier-version", "2012-06-01");

// Get the access policy for the "chilkat" vault.
let sb_response_body = chilkat::StringBuilder::new();
if rest.full_request_no_body_sb("GET", "/AWS_ACCOUNT_ID/vaults/chilkat/access-policy", &sb_response_body).is_err() {
    println!("{}", rest.last_error_text());
    return;

let json_policy = chilkat::JsonObject::new();
let _ = json_policy.load(&json.string_of("Policy").unwrap_or_default());
json_policy.set_emit_compact(false);

println!("{}", json_policy.emit().unwrap_or_default());
println!("----");

// The jsonPolicy contains:
