【旧代码整理】uri路由处理部分

来源：互联网发布：wine源码编辑：程序博客网时间：2024/06/05 02:18

一个简单的php mvc框架的代码说明，uri路由处理部分：

/project/application_www/public/index.php

接收到除静态文件外的所有请求，然后 requeire application_admin/init.php 和 /project/init.php 和 /project/run.php

<?phpdefine('PUBLIC_PATH',dirname(__file__));require  '../init.php';require APPLICATION_PATH . '/../run.php';?>

requeire application_admin/init.php

看上去很简单。这里是放局部的初始化配置信息是，但是暂无东西配置，直接require最高级 init.php了

<?phpdefine('APPLICATION_PATH',dirname(__file__));require APPLICATION_PATH . '/../init.php';

/project/run.php

run.php 负责根据 uri 解析出 controller 和 action 、以及params，然后调用对应/project/controller/目录中的contrller class文件，执行action。

<?php$uri = $_SERVER['REQUEST_URI'];$_SGLOBAL = array();$route = Model_Route::get($uri);if(empty($route['controller'])){_Error_404();exit;}else{$_SGLOBAL['controller'] = $route['controller'];$_SGLOBAL['action'] = $route['action'];if(isset($route['params'])){$_SGLOBAL['params'] = $route['params'];}}$file = APPLICATION_PATH . '/controller/' . $_SGLOBAL['controller'] . '.php';if(file_exists($file)){require $file;}else{echo "file not found:{$file}";die();_Error_404();}$class = "Controller_{$_SGLOBAL['controller']}";$action = "action_{$_SGLOBAL['action']}";$obj = new $class;$obj->$action();

/project/application_www/route.php

uri 的路由配置文件；

<?php$_route = array("index_index" => array('url' => '/','controller' => 'index','action' => 'index',),"user_login" => array('url' => '/login','controller' => 'user','action' => 'login',),"user_logout" => array('url' => '/logout','controller' => 'user','action' => 'logout',),"user_setting" => array('url' => '/user_setting/<act>(-<uid>)','controller' => 'user','action' => 'setting','params' => array('default' => array('act'=>'view','uid'=>0),'pattern' => array('act'=>'\w+','uid'=>'\d+'),),),?>

给route举个栗子：

浏览器访问 http://www.domain.com/user_setting/view/1001 时，nginx将除静态和图片文件以外的所有request发到/project/application_www/public/index.php

1、index.php 接收到请求，加载init.php 和 run.php

2、init.php 初始化必要的基本配置后，run.php开始解析uri，调用controller的action user.php 的 method：setting()，并且传入参数act=view,uid=1001，

run.php解析的参数，可以由/project/library/function.php 的 function _get() 取得

/project/run.php 的 Model_Route::get($uri) class，位于 /project/model/route.php[点我]
