Implementation

Future<GetKeyPolicyResponse> getKeyPolicy({
  required String keyId,
  String? policyName,
}) async {
  final headers = <String, String>{
    'Content-Type': 'application/x-amz-json-1.1',
    'X-Amz-Target': 'TrentService.GetKeyPolicy'
  };
  final jsonResponse = await _protocol.send(
    method: 'POST',
    requestUri: '/',
    exceptionFnMap: _exceptionFns,
    // TODO queryParams
    headers: headers,
    payload: {
      'KeyId': keyId,
      if (policyName != null) 'PolicyName': policyName,
    },
  );

  return GetKeyPolicyResponse.fromJson(jsonResponse.body);
