Yaf的路由器, 负责分析请求中的request uri, 得出目标模板, 控制器, 动作.

在PHP5.3之后, 打开yaf.use_namespace的情况下, 也可以使用 Yaf\Router

 
    final 
    Yaf_Router
    {
  
    protected 

    array 

    
     _routes
    
   ;
  
    protected 

    string 

    
     _current_route
    
   ;
  public Yaf_Router 
     
      addRoute
     
    (
     string 
     $name
    ,
                                                     
     Yaf_Route_Interface 
     $route
    );
  public boolean 
     
      addConfig
     
    (
     Yaf_Config_Abstract 
     $routes_config
    );
  public array 
     
      getRoutes
     
    (
     void 
    );
  public array 
     
      getRoute
     
    (
     string 
     $name
    );
  public string 
     
      getCurrentRoute
     
    (
     void 
    );
  public boolean 
     
      route
     
    (
     Yaf_Request_Abstract 
     $request
    );
  public boolean 
     
      isModuleName
     
    (
     string 
     $name
    );
}

属性说明

Yaf的路由需要Web服务器把非静态资源的请求都转发到入口脚本, 以下是几种常见Web服务器的重写配置.

Apache:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]

Nginx:

server {
  listen 80;
  server_name yourdomain.com;
  root document_root;
  index index.php index.html;

  if (!-e $request_filename) {
    rewrite ^/(.*) /index.php/$1 last;
  }
}

Lighttpd:

url.rewrite-once = (
  ".*\?(.*)$" => "/index.php?$1",
  ".*\.(js|ico|gif|jpg|png|css|html)$" => "$0",
  "" => "/index.php"
)
