Configure AWS Signature Authentication for REST

See more REST Examples

Demonstrates Rest.SetAuthAws, which associates an AuthAws provider so Chilkat signs each request using AWS Signature Version 4. The provider supplies the access key, secret key, region, and service name.

import 'package:chilkat/chilkat.dart';

void main() {
  final rest = CkRest();
  final bTls = true;
  final bAutoReconnect = true;
  try {
    rest.connect('example.com', 443, bTls, bAutoReconnect);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Configure AWS Signature Version 4 request signing.  Provide the access key, secret key, region,
  // and service name.
  final authAws = CkAuthAws();
  // Normally you would not hard-code secrets in source.  You should instead obtain them from an
  // interactive prompt, environment variable, or a secrets vault.
  authAws.accessKey = 'AWS_ACCESS_KEY';
  authAws.secretKey = 'AWS_SECRET_KEY';
  authAws.region = 'us-east-1';
  authAws.serviceName = 's3';

  // Associate the provider so Chilkat signs each request according to AWS requirements.
  try {
    rest.setAuthAws(authAws);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  final String responseText;
  try {
    responseText = rest.fullRequestNoBody('GET', '/');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  print(responseText);
}
