微信问题，求大神搭救。验证过TOKEN后收不到消息
为什么验证过TOKEN后，无论怎么样都接收不到微信的消息，求大神解救！！下面是代码define('TOKEN', 'weixin');//define('DEBUG', FALSE);//是否开启调试模式
class Wxapi extends CI_Controller
{
public function __construct()
{
parent::__construct();
}
public function index() {
//$this->valid();
$this->responseMsg();
}
public function valid()
{
$echoStr = $_GET["echostr"];
if($this->checkSignature()){
echo $echoStr;
exit;
}
}
public function responseMsg()
{
$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
if (!empty($postStr)){
$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
$fromUsername = $postObj->FromUserName;
$toUsername = $postObj->ToUserName;
$keyword = trim($postObj->Content);
$time = time();
$textTpl = "<xml>
<ToUserName><!]></ToUserName>
<FromUserName><!]></FromUserName>
<CreateTime>%s</CreateTime>
<MsgType><!]></MsgType>
<Content><!]></Content>
<FuncFlag>0<FuncFlag>
</xml>";
if(!empty( $keyword ))
{
$msgType = "text";
$contentStr = '你好啊，屌丝';
$resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);
echo $resultStr;
}else{
echo '咋不说哈呢';
}
}else {
echo '咋不说哈呢';
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;
}
}
}
