详解php框架Yaf路由重写

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,
      ),
    )
  );
