示例1: retrieveData
/**
* Retrieve a remote REST resource
*
* @param string full URL to this resource
* @param array|false contents of the accept-encoding header
* @param boolean if true, xml will be returned as a string, otherwise, xml will be
* parsed using Pyrus\XMLParser
* @param string|false if string, this will override the recieved content-type and can enforce a parser.
*
* @return string|array
*
* @throws Pyrus\REST\Exception If the xml cannot be parsed
