Options Hash (token_params):

  • :client_id (String) —

    A client ID to associate with this token. The generated token may be used to authenticate as this client_id

  • :ttl (Integer) —

    validity time in seconds for the requested Models::TokenDetails. Limits may apply, see https://www.ably.com/docs/general/authentication

  • :capability (Hash) —

    canonicalised representation of the resource paths and associated operations

  • :timestamp (Time) —

    the time of the request

  • :nonce (String) —

    an unquoted, unescaped random string of at least 16 characters

Options Hash (auth_options):

  • :auth_url (String) —

    a URL to be used to GET or POST a set of token request params, to obtain a signed token request

  • :auth_headers (Hash) —

    a set of application-specific headers to be added to any request made to the auth_url

  • :auth_params (Hash) —

    a set of application-specific query params to be added to any request made to the auth_url

  • :auth_method (Symbol) — default: :get —

    HTTP method to use with auth_url, must be either :get or :post

  • :auth_callback (Proc) —

    when provided, the Proc will be called with the token params hash as the first argument, whenever a new token is required. The Proc should return a token string, Models::TokenDetails or JSON equivalent, Models::TokenRequest or JSON equivalent

  • :key (String) —

    API key comprising the key name and key secret in a single string

  • :client_id (String) —

    client ID identifying this connection to other clients (will use client_id specified when library was instanced if provided)

  • :query_time (Boolean) —

    when true will query the Ably system for the current time instead of using the local time

  • :token_params (Hash) —

    convenience to pass in token_params within the auth_options argument, especially useful when setting default token_params in the client constructor
