3.扫描HTTP端口（在线版本）

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>JS Bin</title>
</head>
<body>
<script>

4.扫描FTP端口（在线版本），略慢

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <title>JS Bin</title>
</head>
<body>
<script src="ftp://50.116.13.6" onload="alert('21 open')"></script>
</body>
</html>
