JavaScript 强制跳转 HTTPS 脚本

HTML 自上而下解析，所以脚本需要放在主页上方；最好的实现方法是服务端或者域名解析的时候做 301 跳转

<script type="text/javascript">
var targetProtocol = "https:";
if (window.location.protocol != targetProtocol)
 window.location.href = targetProtocol +
  window.location.href.substring(window.location.protocol.length);
</script>
<script type="text/javascript">
var hosts = /^(192.168.1.)/;
    if (window.location.hostname !== 'localhost' && !hosts.test(window.location.hostname)) {
      // 判断非本地 server 时 http 强制转换成 https
      var targetProtocol = "https:";
      if (window.location.protocol != targetProtocol)
      window.location.href = targetProtocol +
      window.location.href.substring(window.location.protocol.length);
    }
</script>
