用户的proxy帐号里api key要设置好，那个key设置后是不显示的，但会显示已设置
key是自已随便生成的
$uid = 22222;
$skey = ‘langansafe&*#‘;
$time = time();
$vhost = ‘liuwei‘;
$data = array(
‘uid‘=>$uid,
‘t‘=>$time,
‘skey‘=>$skey,
‘vhost‘=>$vhost,
‘sign‘=>md5(md5($uid.$skey).$time),
);
$url = "https://www.test.com/api2/site/index.php/token";
$str = $this->curl($url,$data);
$re = json_decode($str,true);
return $re;
