本人在SAE环境下搭建了CI框架(其实这个小东西用不着用框架的)，直接把代码写在了控制器里面

//define your token

define("TOKEN", "109");

class Welcome extends CI_Controller {

public function index()

{

/*

$this->load->helper('url');

$this->load->view('welcome_message');

*/

// use chat response

$this->responseMsg();

}

// chat response

public function responseMsg()

{

//get post data, May be due to the different environments

$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];

//extract post data

if (!empty($postStr)){
