  access_token_secret: "token_secret"
)

Parameters:

  • api_key (String) —

    the API key (consumer key)

Instance Method Details

#headers(request) ⇒ Hash{String => String}

Generate the OAuth authentication headers for a request

The signature covers the HTTP method, the URL, its query parameters, and a form-encoded body. Bodies of any other media type, such as the JSON and multipart bodies the X API takes, are not signed.

Examples:

Generate an OAuth authentication header

authenticator.headers(request)

Parameters:

  • request (#http_method, #uri, #body, #[]) —

    the request, whose method, uri, body, and Content-Type the signature reads

Returns:

  • (Hash{String => String}) —

    the authentication header with OAuth signature

def headers(request)
  oauth_header = SimpleOAuth::Header.new(request.http_method, request.uri, form_params(request), credentials)
  {AUTHENTICATION_HEADER => oauth_header.to_s}
end

#user_id ⇒ Integer?

The identifier of the user the access token acts for

An OAuth 1.0a access token begins with the identifier of the user who authorized it, so a client that signs with one knows the user it acts for without asking the API.

Examples:

Read the user a client acts for without a request

client.authenticator.user_id # => 7505382

Returns:

  • (Integer, nil) —

    the identifier, or nil for a token that begins with none
