Build PHP Laravel Class and complete missing functionality

Build a Laravel class that is available throughout the cycle of an HTTP web request This must be setup as a small application able to receive an HTTP Post Request, in order to test. It will receive several parameters: This Laravel class will receive an $params array as follows: $params = array( "scrubber" => "AcuityTec", "token" => "some guid value (ex: bccc1fe7-e745-4343-b53b-6145993f177e)" "load" => "base|decision|errors|fields_full_new_request|...", "params" => array( "function" => "convert", "params" => array( "source" => "sys", "destination" => "variable" ) ) ) According to the "load" parameter it will use (if already created) or create (if not instantiated yet), a class in "\app\Scrubber" According to the "scrubber" parameter and the "load" parameter, the new class will load and parse an xml in \app\Scrubber\plugins\[Scrubber], for example, if [Scrubber] = "AcuityTec" and "load" is "base": - will instantiate \app\Scrubber\ScrubberConfBase if not exist or use if already exist - will load and \app\Scrubber\plugins\AcuityTec\[login to view URL] Important: - Do not use Session variables - the classes must be instantiated once - the created object must exist throughout the request, must be accessible whole application - use Orchestra xml parser functions of each class: ScrubberConfBase: - getSettingValue("[setting]"): returns the value for that setting. - getScrubbTypes() return simple array of supported (value="true" && type="boolean") scrubbTypes - getCredentials() return associative array of credentials (setting => value) ScrubberConfDecision: - getConvert($params) ($contains for example: array("token" => "bccc1fe7-e745-4343-b53b-6145993f177e", "score" => 2.5) ): returns "convert" attribute for given token (if token not found returns from default) >> if type = range it must validate $score according to "value" range ScrubberConfErrors: - getDescription($error) returns "description" for a given error code - getConvert($error) return "convert" for the given $error value ScrubberConfReasons: - getDescription($reason) returns the "description" for a given reason code - getConvert($reason) return "convert" for the given $reason value ScrubberConfScore: - getConvert($score) (example: "score" => 2.5): returns the "convert" attribute for the given score >> if type = range it must validate the provided $score falls in valid "value" range ScrubberConfStatus: - getConvert($status) returns "convert" value for the provided $status ScrubberConfSuggest: - getConvert($suggest) returns the "convert" value for the provided $suggest ScrubberField: when loaded, it must parse the HTTP Request post parameters, - validated (according to "validator") items go into assoc-array/object-array - missing or failed-validation required="true" items - missing or failed-validation required="false" items for example loads: [login to view URL] (represents data fields received in POST request by remote client application) - getItemId($params) "params" => array( "source" => "variable", "destination" => "sys", "item" => "session_id" ) returns the "sys" for given "variable" - getItemId($params) "params" => array( "source" => "sys", "destination" => "variable", "item" => "sysSessionId" ) returns the "variable" for given "sys" value - getValue($params) "params" => array( "source" => "sys|variable", "item" => "sysSessionId|session_id" ) returns the value of the Post Parameter (post parameter names are the ones defined in the "sys" attributes) - getRequestParams() returns associative array ("key" => "value") with "variable" as key and post value (based on the "sys" attribute ) - getErrors() returns array of errors - getWarnings() returns array of warnings - getErrorCount() returns # of errors
