// (
// [actionname] => read
// [modulename] => news
// [extra] => 2012
// [status] => 1
// [extraparam] => test
// [year] => 2012

// [finalurl] => news/read?extra=2012&status=1&extraparam=test&year=2012&month=2&day=21
// )
// [finished in 0.6s]
//相当于访问: http://www.test.com/news/read?extra=2012&status=1&extraparam=test&year=2012&month=2&day=21
//在部署时会把index.php隐藏，开启apache的重写模块
//重写规则 ： rewriterule ^(.+)$ /index.php/$1
//开启后，apache会自动把 http:/www.test.com/news/read/2012/2/21/extraparam/test.html转换为 http:/www.test.com/index.php/news/read/2012/2/21/extraparam/test.html
