java - 如何知道该网站是否是通过移动设备访问的

Question

我在 asp.net 中遇到了这个问题，但我正在搜索 Scala 或 Java:

How to know if the asp.net site is accessed from a mobile device or from a system/laptop/machine(windows,mac etc)

有什么办法或者我在移动请求的请求浏览器中设置它。

 def check = Action { implicit request =>
     try{
       println(request.headers)
    Ok(write(Map("result"->true)))
    }catch{
      case e:Exception=>
        Ok(write(Map("result"->false)))
    }
  }

我尝试了来自网络的上述请求，iPhone 和 Android 提供了这些信息

您可以使用UADetector解析 User-Agent header 。通过使用ReadableUserAgent#getDeviceCategory ，您可以检测是否来自智能手机。

它可以在 Apache 许可证 2.0 下免费使用。
