Constructor Details

#initialize(args) ⇒ DefaultConnection

Returns a new instance of DefaultConnection.

Parameters:

  • args (Hash) —

    the parameters to initialize the connection with

Options Hash (args):

  • :connect_timeout (Integer) —

    connection timeout in seconds.

  • :socket_timeout (Integer) —

    socket timeout in seconds.

  • :max_connections (Integer) —

    number of connections kept alive in the thread pool. Uses CommunicatorConfiguration.DEFAULT_MAX_CONNECTIONS if not given.

  • :proxy_configuration (Ingenico::Connect::SDK::ProxyConfiguration) —

    object that stores the proxy to use. If not given the system default proxy is used; if there is no system default proxy set either, no proxy is used.

Raises:

  • (ArgumentError)

Instance Method Details

#close ⇒ Object

Frees all networking resources used.

def close
  @http_client.reset_all
end

#close_expired_connections ⇒ Object

HTTPClient automatically closes expired connections so close_expired_connections is a no-operation.

# File 'lib/ingenico/connect/sdk/defaultimpl/default_connection.rb', line 105

def close_expired_connections
  # By default the keep alive timeout is 15 sec, which is the HTTP 1.1
  # standard. To change the value, use keep_alive_timeout= method
  # do nothing, handled by HTTPClient
end

#close_idle_connections(idle_time) ⇒ Object

Closes all connections idle for longer than idle_time seconds. In addition, the keep_alive_timeout is set to idle_time so any future connections idle for longer than idle_time seconds will also be closed.

def disable_logging
  @communicator_logger = nil
end

#enable_logging(communicator_logger) ⇒ Object

Enables logging outgoing requests and incoming responses by registering the communicator_logger. Note that only one logger can be registered at a time and calling enable_logging a second time will override the old logger instance with the new one.

end

#request(method, uri, request_headers, body = nil) {|Integer, Array<Ingenico::Connect::SDK::ResponseHeader>, IO| ... } ⇒ Object

Performs a HTTP request and yields the response as the status code, headers and body. Also ensures the request is logged when sent and its response is logged when received.

Parameters:

  • method (String) —

    ‘GET’, ‘DELETE’, ‘POST’ or ‘PUT’ depending on the HTTP method being used.

  • uri (URI::HTTP) —

    full URI of the location the request is targeted at, including query parameters.

  • request_headers (Array<Ingenico::Connect::SDK::RequestHeader>) —

    list of headers that should be used as HTTP headers in the request.

  • body (String, Ingenico::Connect::SDK::MultipartFormDataObject) (defaults to: nil) —

    request body.
