Constructor Details

#initialize(options = {}) ⇒ Presigner

Returns a new instance of Presigner.

Parameters:

  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :client (Client) —

    Optionally provide an existing Polly client.

  • :credentials (Credentials) —

    This option is deprecated, please use :client instead. Provide an object that responds to ‘#credentials` that returns another object that responds to `#access_key_id`, `#secret_access_key`, and `#session_token`.

    For example, you could provide an instance of following classes:

    * `Aws::Credentials`
* `Aws::SharedCredentials`
* `Aws::InstanceProfileCredentials`
* `Aws::AssumeRoleCredentials`
* `Aws::ECSCredentials`
  • :region (String) —

    This option is deprecated, please use :client instead. The region name, e.g. ‘us-west-2’.
