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。

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

//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 (!emptyempty($postStr)){



      $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);

      $fromUsername = $postObj->FromUserName;

      $toUsername = $postObj->ToUserName;

      $MsgType = $postObj->MsgType;

      $time = time();



      switch($MsgType){

        case('text'):

          $keyword = trim($postObj->Content);

          $textTpl = "<xml>

                <tousername></tousername>

                <fromusername></fromusername>

                <createtime>%s</createtime>

                <msgtype></msgtype>

                <content></content>

                </xml>";

          switch($keyword){

            case(1):

              // Need to optimize

              // random read data from jokes

              $sql = 'SELECT * FROM jokes';

              $query = $this->db->query($sql);

              $res = $query->result_array();

              $num_rows = $query->num_rows();

              $key = rand(0, $num_rows - 1); // Notice: The value of key is from 0.

              //$contentStr = $key.'#'.$res[$key ]['content']; // debug

              $contentStr = $res[$key ]['content'];

              break;
