通过控制器实现类似Java的工厂模式

在主入口文件中通过DIRECTORY_SEPARATOR和dirname(__FILE__)以及url中的参数拼接控制模块文件，通过include 进入子控制模块

$l = DIRECTORY_SEPARATOR;

$dir = dirname(__FILE__);

$ctrlName = trim($operation);

$controllerFile = "{$dir}{$l}目录名{$l}xxx{$ctrlName}.php";

if (file_exists($controllerFile)) {

include $controllerFile;

}else {

aaa(-1,lang ( "message", "undefined_action" ));

}

在子控制模块文件中判断逻辑返回json字符串

function aaa($result, $message, $data = array()) {

$jdata['result'] = $result;

$jdata['message'] = $message;

if(!empty($data)){

$jdata['data'] = $data;

}

echo json_encode($jdata);

exit;

}
