    判断网址协议可能这样更好点
    $WebSite = (((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') || (isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https')) ? 'https://' : 'http://') . $_SERVER['HTTP_HOST'];

    $WebSite = (isHTTPS() ? 'https://' : 'http://') . $_SERVER['HTTP_HOST'];这种格式在360或谷歌执行不了

     shuangrong 判断网址协议可能这样更好点 $WebSite = (((isset($_SERVER['HTTPS']) &amp;&amp; $_SERVER['HTTPS'] == 'on') | ...

    function isSecure() {
    return (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off') || $_SERVER['SERVER_PORT'] == 443;
    }
