我有我的 nginx conf 文件，这样每当移动设备访问我的网站时，url 都会被重写为 m.mysite.com，我通过添加以下内容来实现

我从http://detectmobilebrowsers.com/ 它可以工作。但我的所有图片/js/css 文件都无法加载，只能加载 HTML。我知道这是我上面提到的代码块，因为当我删除它并从我的移动设备访问 m.mywebsite.com 时，所有内容都会加载。所以这段代码对我的 css/img/js MIME 类型有影响。我通过 Safari 的控制台错误消息发现了这一点，其中用户代理设置为 iphone。

我可以用 php 或 javascript 检测移动浏览器，但我需要在服务器级别进行检测，以便我可以使用 m.mywebsite.com 中的“m”作为控制器 (codeigniter) 中的标志来提供正确的视图。希望有人能帮助我！谢谢！
答案1
您为访问 的客户端提供来自哪个虚拟主机的图像m.mywebsite.com？如果仍从 提供图像www.mywebsite.com，则客户端将为其请求的每个图像获得重定向，某些浏览器可能无法正确处理。如果您对所有图像都使用相对链接，则应从 提供图像m.mywebsite.com，在这种情况下，nginx 配置www.mywebsite.com根本不会影响它（初始重定向除外）。
