PHP

<?php

require_once(‘Log/LogHelper.php‘);
WriteLog(‘Ajax_GridView_Select---------‘);

foreach($_POST as $k=>$v){    
    WriteLog("POST ". $k .‘--‘ .$v);    
}    
foreach($_GET as $k=>$v){    
    WriteLog("GET ".  $k .‘--‘ .$v);    
}

$json_request=file_get_contents("php://input");  //取请求过来的 JSON
WriteLog( $json_request );
$arr_request = json_decode($json_request,true);
//输出var_dump($arr);
WriteLog("arr_request0 " . $arr_request[0]);
WriteLog("arr_request1 " . $arr_request[1]);

$arr_result = array(); //返回值  

$arr_result[‘rows‘] = "EEEEEEEEE";     
$arr_result[‘action‘] = "黑名单"; 
//echo json_encode($arr_result );
echo encode_json($arr_result);


   //php 5.4版本之前json_encode的option里未添加JSON_UNESCAPED_UNICODE,需自定义函数处理
   function encode_json($str)
   {
       return urldecode(json_encode(url_encode($str)));
   }
   function url_encode($str)
   {
     if(is_array($str))
      {
          foreach($str as $key=>$value)
          {
              $str[urlencode($key)] = url_encode($value);
          }
      }
      else
      {
          $str = urlencode($str);
