通常为了友好的URL格式，会进行站点URL的重写，可以在webserver(Nginx)的配置中进行rewrite，也可在在程序端进行

以下使用Yaf框架进行URL的重写，进行一些整理，方便日后查看

YAF的URL重写方式主要有以下几种，可以综合使用

方式1：在配置文件中进行

;a rewrite route match request /product/*/*
routes.route_name.type="rewrite"
routes.route_name.match="/product/:name/:value"
routes.route_name.route.controller=product
routes.route_name.route.action=info

;a regex route match request /list/*/*
routes.route_name1.type="regex"
routes.route_name1.match="#^list/([^/]*)/([^/]*)#"
routes.route_name1.route.controller=Index
routes.route_name1.route.action=action
routes.route_name1.map.1=name
routes.route_name1.map.2=value

;a simple route match /**?c=controller&a=action&m=module
routes.route_name2.type="simple"
routes.route_name2.controller=c
routes.route_name2.module=m
routes.route_name2.action=a

;a simple router match /**?r=PATH_INFO
routes.route_name3.type="supervar"
routes.route_name3.varname=r

;a map route match any request to controller
routes.route_name4.type="map"
routes.route_name4.controllerPrefer=TRUE
routes.route_namer.delimiter="#!"

之后在Bootstrap.php中添加初始化函数，函数名可按自己需求取，必需以_开头才会被调用

<?php
class Bootstrap extends Yaf_Bootstrap_Abstract{
    public function _initConfig() {
        $config = Yaf_Application::app()->getConfig();
        Yaf_Registry::set("config", $config);
    }

    public function _initRoute(Yaf_Dispatcher $dispatcher) {
        $router = $dispatcher->getRouter();
        /**
         * we can add some pre-defined routes in application.ini
         */
        $router->addConfig(Yaf_Registry::get("config")->routes);
        /**
         * add a Rewrite route, then for a request uri: 
         * http://***/product/list/22/foo
         * will be matched by this route, and result:
         *
         *  [module] => 
         *  [controller] => product
         *  [action] => info
         *  [method] => GET
         *  [params:protected] => Array
         *      (
         *          [id] => 22
         *          [name] => foo
         *      )
         * 
         */
        $route  = new Yaf_Route_Rewrite(
            "/product/list/:id/:name",
            array(
                "controller" => "product",
                "action"     => "info",
            )
        ); 
        
        $router->addRoute('dummy', $route);
    }
?>

方式2:直接在程序中，以数组方式配置
以下函数是放在Bootstrap.php中

public function _initRoute(Ap_Dispatcher $dispatcher) {
    //在这里注册自己的路由协议,默认使用static路由
    $router = Ap_Dispatcher::getInstance()->getRouter();
    $routeConfig = array(
    $router = Ap_Dispatcher::getInstance()->getRouter();
    $routeConfig = array(
        "item" => array(
            "type"  => "regex",
            "match" => "#^/(software|game)/(.*).html$#",
            "route" => array('action' => 'item'),
            "map" => array( 1 => 'data_type', 2 => 'docid' ),
        ),
        //正则匹配
        "category" => array(
            "type"  => "regex",
            "match" => "#^/(software|game|video)/(.*)/(list_(.*).html)?$#",
            "route" => array('action' => 'list' ),
            "map" => array( 1 => 'data_type', 2 => 'cid',4 => 'page_num' ),
        ),
        //使用动态结果 :a 表示action
        "name" => array(
           "type"  => "rewrite",        //Yaf_Route_Rewrite route
           "match" => "/user-list/:a/:id", //match only /user-list/开头的
           "route" => array(
               'controller' => "user",  //route to user controller,
               'action'     => ":a",  //使用动态的action
           ),
        ),
    );
    $router->addConfig(new Ap_Config_Simple($routeConfig));
}

方式3:

   /**
    * Add a rewrite route to Yaf_Router route stack
    */
    Yaf_Dispatcher::getInstance()->getRouter()->addRoute("name",
        new Yaf_Route_rewrite(
           "/product/:name/:id/*", //match request uri leading "/product"
           array(
               'controller' => "product",  //route to product controller,
           ),
        )
    );
