今天购入阿里云，然后准备在阿里云上搭建rest风格的API，首先就是URL规则重写
1、URL重写
在apache服务器下，修改httpd.conf文件
(1)Options FollowSymLinks
AllowOverride None
改为
Options FollowSymLinks
AllowOverride All
(2)去掉下面的注释
LoadModule rewrite_module modules/mod_rewrite.so
2、根目录下添加.htaccess文件，完成重写规则
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ index.php?_url=/$1 [QSA,L]
3、实现index.php
首先是define相关的文件夹路径，比如：
//根路径
define('ROOT_PATH',dirname(__FILE__));
define('CONF_PATH',ROOT_PATH.'/conf/');
然后调用dispatch做分发处理
4、实现dispatch.php
通过获取请求参数来分发到不同的文件和方法中
public function dealUrl(){
$url =strip_tags( $_SERVER['REQUEST_URI'] );
$pathseg =explode('/',trim($url,'/'));
$method = Http_Request::get('method');
if(is_null($method)){
throw new Exception('not_found');
}
$resseg =explode('?',trim($pathseg[1],'?'));
$args[] = $resseg[0];
$strFileName =CONTROLLER_PATH.$resseg[0]."Controller.php";
$this->_controllerFile=$resseg[0]."Controller.php";
$this->_strControllerName= $resseg[0];
if(is_file($strFileName)) {
include_once'Controller.php';
include_once$strFileName;
if(!class_exists($this->_strControllerName)) {
throw newException('not_found');
return'false';
}
$objController =new$this->_strControllerName();
if(!method_exists($objController,$method)){
throw newException('not_found');
}
$objController->$method();
}
}
大工告成！
