lithium\action\Request::__construct()

Overrides lithium\core\ObjectDeprecated::__construct()
public method

Constructor. Adds config values to the public properties when a new object is created, pulling request data from superglobals if globals is set to true.

Normalizes casing of request headers.

Parameters

  • array $config

    The available configuration options are the following. Further options are inherited from the parent classes.

    • 'base' string: Defaults to null.
    • 'url' string: Defaults to null.
    • 'data' array: Additional data to use when initializing the request. Defaults to array().
    • 'stream' resource: Stream to read from in order to get the message body when method is POST, PUT or PATCH and data is empty. When not provided php://input will be used for reading.
    • 'env' array: Defaults to array().
    • 'globals' boolean: Use global variables for populating the request's environment and data; defaults to true.
    • 'drain' boolean: Enables/disables automatic reading of streams. Defaults to true. Disable when you're dealing with large binary payloads. Note that this will also disable automatic content decoding of stream data.

Returns

void
