$data = $this->helper->xmlToArr ( $msg );
   $fromUsername = $data['FromUserName'];
   $toUsername = $data['ToUserName'];
   $msgType = trim($data['MsgType']);
   //默认返回
   $sendtime = time();
    $sendtextTpl = "<xml>
<ToUserName><![CDATA[%s]]></ToUserName>
<FromUserName><![CDATA[%s]]></FromUserName>
<CreateTime>%s</CreateTime>
<MsgType><![CDATA[%s]]></MsgType>
<Content><![CDATA[%s]]></Content>
<FuncFlag>0</FuncFlag>

</xml>"; 

第一步：

if($toUsername == "gh_3c884a361561")
    {
    $sendMsgType = "text";
    $sendContentStr = $event."from_callback";
  $sendResultStr = sprintf($sendtextTpl, $fromUsername, $toUsername, $sendtime, $sendMsgType, $sendContentStr);
    $encryptMsg = $this->encode_msg($sendResultStr, $timeStamp, $nonce, $encryptMsg);
return $encryptMsg;
    }

第二步：

$keyword = trim($data['Content']);

if($toUsername == "gh_3c884a361561" && $keyword == "TESTCOMPONENT_MSG_TYPE_TEXT")
    {
    $sendMsgType = "text";
    $sendContentStr = "TESTCOMPONENT_MSG_TYPE_TEXT_callback";
  $sendResultStr = sprintf($sendtextTpl, $fromUsername, $toUsername, $sendtime, $sendMsgType, $sendContentStr);
    $encryptMsg = $this->encode_msg($sendResultStr, $timeStamp, $nonce, $encryptMsg);
return $encryptMsg;
    }

第三步：

if($toUsername == "gh_3c884a361561" && strpos($keyword, "QUERY_AUTH_CODE") > -1)
    {
    $ticket = str_replace("QUERY_AUTH_CODE:", "", $keyword);
    include_once "wxAuthLib.php";
   
    $wxAuthLib = new wxAuthLib();
    $res = $wxAuthLib->getAuthorizationAppid($ticket); //使用授权码换取公众号的接口调用凭据和授权信息
    //$this->helper->set_php_file(dirname(__FILE__)."/test.php", json_encode($res)); 
    if($res != "")
    {
    $authorizer_access_token = $res['authorization_info']['authorizer_access_token'];
    $url = "https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=".$authorizer_access_token;
    $curlPost['touser'] = $fromUsername;
    $curlPost['msgtype'] = "text";

    $curlPost['text']['content'] = $ticket."_from_api";
    $curlPost = json_encode($curlPost);
       $res = json_decode($this->helper->httpPost($curlPost, $url), true);
    //$this->helper->set_php_file(dirname(__FILE__)."/test.php", $authorizer_access_token);
   
    }
    return "";
    }

在发布之前首先需要完成整个授权流程，前2步发送的信息都需要加密发送。
