php ioc and web rest design

三個核心文件

1.公開訪問web service配置 config.php

2.管理BEAN，掃描，註冊，初始化等流程 ioc.php

3.管理 rest 攔載處理 ws.php

config.php

<?php
    /**
     * @author solq
     * @deprecated blog http://solq.cnblogs.com
     */
    $_suffix = ".php";    
    $_beans=array(
        'TestRef',
    ); 
    /**容器註冊類*/
    $_ioc= array();
    $_app_path_index=1;
?>

ioc.php

 

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

include_once "config.php";
/**
掃描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);
    }
}

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

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

/**容器註冊後期階段*/
function postConstruct_bean(){
    global  $_ioc;
    foreach($_ioc as $bean){    
        if (is_subclass_of($bean, 'Ioc')) {
            $bean->{"setIoc"}($_ioc);
            $bean->{"postConstruct"}();
        }  
    }
}
/**容器銷燬階段*/
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'];
$segments=explode('/',trim($page,'/'));

global $_app_path_index;
//應用

//服務
$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();

/**
獲取請求方式
*/
function get_request_method(){
    return strtolower($_SERVER['REQUEST_METHOD']);

    }
    
    foreach($reflection->getParameters() as $param) {        
        //數據類型注入分解
        $value = $args[$param->getName()];
        if($value==null && !$param->isDefaultValueAvailable()){
            throw new Exception("method [".$method."] param is not :".$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(){
     }
   
    /**
        書寫約定
        [請求方式]_[服務]
    */
     public function get_test1($a,$b,$c=null){
        echo $this->one."\n";
        echo $b."\n";
        echo $c."\n";
    }
    
    public function preDestroy(){
        echo "<br/>postConstruct_bean";
    }
}
?>
