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
<?phpif(!defined('BASEPATH'))exit('Nodirectscriptaccessallowed');
//defineyourtoken
define("TOKEN","109");
classWelcomeextendsCI_Controller{
publicfunctionindex()
{
/*
$this->load->helper('url');
$this->load->view('welcome_message');
*/
//usechatresponse
$this->responseMsg();
}
//chatresponse
publicfunctionresponseMsg()
{
//getpostdata,Maybeduetothedifferentenvironments
$postStr=$GLOBALS["HTTP_RAW_POST_DATA"];
//extractpostdata
