php ioc and web rest design

浏览数：27 / 时间：2015年06月09日

三个核心文件

1.公开访问web service配置 config.php

2.管理BEAN，扫描，注册，初始化等流程 ioc.php

3.管理 rest 拦载处理 ws.php

config.php

<?php
    /**
     * @author solq
     * @deprecated blog http://solq.cnblogs.com
     */
    $_suffix = ".php";    
    $_beans=array(
        ‘TestRef‘,
    ); 
    /**容器注册类*/
    $_ioc= array();
    $_app_path_index=1;
?>

ioc.php

<?php
    /**
     * @author solq
     * @deprecated blog http://solq.cnblogs.com
     */

include_once "config.php";
/**
扫描BEAN
*/
function scan_bean(){
    global $_suffix;
    global $_beans;
    global $_ioc;    

    for($i=0;$i<count($_beans);$i++){ 
        $name = $_beans[$i];
        $file = $name.$_suffix;
        include_once $file;
        register_bean($name,new $name);
    }
}

/**注册BEAN*/
function register_bean($name,$bean){
    global  $_ioc;    
    $_ioc[$name]=$bean;
}

/**获取BEAN*/
function get_bean($name){
    global  $_ioc;
    return  $_ioc[$name];
}

/**容器注册后期阶段*/
function postConstruct_bean(){
    global  $_ioc;
    foreach($_ioc as $bean){    
        if (is_subclass_of($bean, ‘Ioc‘)) {
            $bean->{"setIoc"}($_ioc);
            $bean->{"postConstruct"}();
        }  
    }
}
/**容器销毁阶段*/
function preDestroy_bean(){
    global  $_ioc;
    foreach($_ioc as $bean){
         if (is_subclass_of($bean, ‘Ioc‘)) {
            $bean->{"preDestroy"}();
        }  
    }
}


interface  Ioc{
    public function postConstruct();
    public function preDestroy();
    public function setIoc($_ioc);
}

abstract class AbstractIoc implements Ioc{
    public function postConstruct(){}
    public function preDestroy(){}
    public function setIoc($_ioc){}
}

?>

ws.php

<?php
    /**
     * @author solq
     * @deprecated blog http://solq.cnblogs.com
     */

include_once "ioc.php";

$page=$_SERVER[‘REQUEST_URI‘];

//应用
$app = $segments[$_app_path_index];
//服务
$service = $segments[$_app_path_index+1];

$method=$service;
$get_params = $_GET;
$post_params = $_POST;

$bean = get_bean($app);

if($bean ==null){
    throw new Exception("bean  [".$app."] not find"); 
}

postConstruct_bean();
___call($bean,$method,$get_params,$post_params);
preDestroy_bean();

/**
获取请求方式
*/
function get_request_method(){
    return strtolower($_SERVER[‘REQUEST_METHOD‘]);

    }
    
    foreach($reflection->getParameters() as $param) {        
        //数据类型注入分解
        $value = $args[$param->getName()];

        }
        $pass[] = $value; 
    }
    return $reflection->invokeArgs($bean, $pass); 
} 
?>

TestRef.php

<?php
include_once "ioc.php";
class TestRef extends AbstractIoc
{
    public $one = ‘aaaaaaaa‘;
    
     public function __construct(){
     }

    }
    
    public function preDestroy(){

?>
