<?php

/**
  * wechat php test
  */

//define your token
define("TOKEN", "你的token");
$wechatObj = new wechatCallbackapiTest();
$wechatObj->valid();


class wechatCallbackapiTest
{
public function valid()
    {
        $echoStr = $_GET["echostr"];


        //valid signature , option
        if($this->checkSignature()){
        echo $echoStr;
        exit;
        }
    }


    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)){
                
              $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
                $fromUsername = $postObj->FromUserName;
                $toUsername = $postObj->ToUserName;
                $keyword = trim($postObj->Content);
                $time = time();
                $textTpl = "<xml>
<ToUserName><![CDATA[%s]]></ToUserName>
<FromUserName><![CDATA[%s]]></FromUserName>
<CreateTime>%s</CreateTime>
<MsgType><![CDATA[%s]]></MsgType>
<Content><![CDATA[%s]]></Content>
<FuncFlag>0</FuncFlag>
</xml>";             
if(!empty( $keyword ))
                {
              $msgType = "text";
                $contentStr = "Welcome to wechat world!";
                $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);
                echo $resultStr;
                }else{
                echo "Input something...";
                }


        }else {
        echo "";
        exit;
        }
    }

private function checkSignature()
{
        $signature = $_GET["signature"];
        $timestamp = $_GET["timestamp"];
        $nonce = $_GET["nonce"];
       
$token = TOKEN;
$tmpArr = array($token, $timestamp, $nonce);
sort($tmpArr);
$tmpStr = implode( $tmpArr );
$tmpStr = sha1( $tmpStr );

if( $tmpStr == $signature ){
return true;
}else{
return false;
}
}
}

?>
