Returns

Type	Description
`Promise<SystemsManagerParameter[]>`	A Promise that fulfills with an array of `SystemsManagerParameter` objects.

Example

import exec from 'k6/execution';

import {
  AWSConfig,
  SystemsManagerClient,
} from 'https://jslib.k6.io/aws/0.14.0/ssm.js';

const awsConfig = new AWSConfig({
  region: __ENV.AWS_REGION,
  accessKeyId: __ENV.AWS_ACCESS_KEY_ID,
  secretAccessKey: __ENV.AWS_SECRET_ACCESS_KEY,
  sessionToken: __ENV.AWS_SESSION_TOKEN,
});

const systemsManager = new SystemsManagerClient(awsConfig);
const testParameterName = 'jslib-test-parameter';
const testParameterValue = 'jslib-test-value';
const testParameterSecretName = 'jslib-test-parameter-secret';
// this value was created with --type SecureString
const testParameterSecretValue = 'jslib-test-secret-value';

export default async function () {
  // Currently the parameter needs to be created before hand

  // Let's get its value
  // getParameter returns a parameter object: e.g. {name: string, value: string...}
  const parameter = await systemsManager.getParameter(testParameterName);
  if (parameter.value !== testParameterValue) {
    exec.test.abort('test parameter not found');
  }

  // Let's get the secret value with decryption
  // destructure the parameter object to get to the values you want
  const { value: encryptedParameterValue } = await systemsManager.getParameter(
    testParameterSecretName,
    true
  );
  if (encryptedParameterValue !== testParameterSecretValue) {
    exec.test.abort('encrypted test parameter not found');
  }
}
