$strData = '';
$d = '';

echo $_GET['echostr'];
die();
}

static function get_access_token($appid,$secret){
$url="https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$appid."&secret=".$secret;
$json=http_request_json($url);//here cannot use file_get_contents
$data=json_decode($json,true);
