网站首页 有时加载不了样式

本帖最后由 yang131261 于 2014-08-15 18:17:14 编辑 做的一个网站,首页有缓存  有时候打开的时候 样式的路径是这样 的   ip地址/css/index.css  首页样式乱了   这个网站一开始用ip:8080访问  绑上域名以后域名访问  但是有时候样式 还是加载的ip的   清除缓存以后  样式的路径换上 域名/css/index.css  首页样式就正常了  首页的缓存采用的是文件缓存

样式的路径采用的是这个函数获得的

<br />function get_http()<br />{<br />    return isset($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) != 'off' ? 'https://' : 'http://';<br />}<br />function get_domain()<br />{<br />    $protocol = get_http();<br />    if (isset($_SERVER['HTTP_X_FORWARDED_HOST'])) {<br />        $host = $_SERVER['HTTP_X_FORWARDED_HOST'];<br />    } elseif (isset($_SERVER['HTTP_HOST'])) {<br />        $host = $_SERVER['HTTP_HOST'];<br />    } else {<br />        if (isset($_SERVER['SERVER_PORT'])) {<br />            $port = ':' . $_SERVER['SERVER_PORT'];<br />            if (':80' == $port && 'http://' == $protocol || ':443' == $port && 'https://' == $protocol) {<br />                $port = '';<br />            }<br />        } else {<br />            $port = '';<br />        }<br />        if (isset($_SERVER['SERVER_NAME'])) {<br />            $host = $_SERVER['SERVER_NAME'] . $port;<br />        } elseif (isset($_SERVER['SERVER_ADDR'])) {<br />            $host = $_SERVER['SERVER_ADDR'] . $port;<br />        }<br />    }<br />    return $protocol . $host;<br />}<br />

------解决方案--------------------
你的网站会是在 http 和 https 间切换吗?
只有在发生切换时才需要产生完整的 url

你 12 行起的,处理端口的代码在什么情况下会执行呢?($_SERVER['HTTP_HOST'] 总是存在的)
处理端口(PORT)和处理 HOST 是平行的,不应该放在 else 分支中
