Authorizer for AWS sigv4 and cassandra-cpp-sys (DataStax cpp driver)
It uses AWS_ACCESS_KEY_ID
, AWS_SECRET_ACCESS_KEY
, AWS_SESSION_TOKEN
, AWS_DEFAULT_REGION
, AWS_REGION
environment variables for configuration.
Example usage with cassandra-rs (cassandra-cpp crate):
use tokio;
use std::fs;
use cassandra_cpp::*;
use cassandra_sigv4::*;
#[tokio::main]
async fn main() {
let mut cluster = Cluster::default();
cluster.set_contact_points("cassandra.eu-central-1.amazonaws.com").unwrap();
cluster.set_port(9142).unwrap();
// Add these lines to use SigV4 authentication
let auth = Authenticator::default();
auth.set_authenticator(cluster.0);
let cert = fs::read_to_string("./sf-class2-root.crt")
.expect("Certificate is missing");
let mut ssl = Ssl::default();
ssl.add_trusted_cert(cert.as_str()).unwrap();
ssl.set_verify_flags(&[SslVerifyFlag::NONE]);
cluster.set_ssl(ssl);
let session = cluster.connect().await.unwrap();
let statement = session.statement("SELECT keyspace_name FROM system_schema.keyspaces");
let result = statement.execute().await.unwrap();
for row in result.iter() {
let keyspace_name: String = row.get(0).unwrap();
println!("Keyspace: {}", keyspace_name);
}
}
