通过Java或JavaScript进行操作系统检测 [英] Operating System Detection by Java or JavaScript

问题描述

我需要检测操作系统名称&Java版本.我可以通过

I need to detect OS name & version in Java. That I can do by

String os_name = System.getProperty("os.name", "");
String os_version = System.getProperty("os.version", "");

，但是问题在于这不可靠.有时它返回错误的信息，并且我无法检测到所有操作系统，除了最流行的Windows，MacOS，Linux等，在64位操作系统的情况下，甚至会提供错误的信息.我需要检测具有任何规格的任何操作系统.我无法为此找到合适的解决方案.

but the problem is that this is not reliable. Sometimes it returns incorrect information, and I can't detect all operating systems, except the most popular Windows, MacOS, Linux etc, and this even provides wrong information in the case of 64 bit operating systems. I need to detect any OS with any kind of specification. I am unable to find the right solution for this.

也许我可以使用JavaScript做到这一点?如果用Java无法实现，请告诉我如何使用JavaScript.

Maybe I can do this with JavaScript? If it's impossible in Java then please tell me how to do it with JavaScript.

任何意见或建议都值得赞赏.

Any input or suggestions highly appreciated.

谢谢.

最诚挚的问候，

推荐答案

在Java中，在猜测操作系统时存在一些常见的错误:

In Java there are some common bugs while guessing the operating system:

也许在Java的较新版本中，它们已解决.

Maybe in newer versions of Java, they are solved.

在Javascript中，您可以使用navigator.appVersion:

In Javascript you can use navigator.appVersion:

// This script sets OSName variable as follows:
// "Windows"    for all versions of Windows
// "MacOS"      for all versions of Macintosh OS
// "Linux"      for all versions of Linux
// "UNIX"       for all other UNIX flavors 
// "Unknown OS" indicates failure to detect the OS

var OSName="Unknown OS";
if (navigator.appVersion.indexOf("Win")!=-1) OSName="Windows";
if (navigator.appVersion.indexOf("Mac")!=-1) OSName="MacOS";
if (navigator.appVersion.indexOf("X11")!=-1) OSName="UNIX";
if (navigator.appVersion.indexOf("Linux")!=-1) OSName="Linux";

document.write('Your OS: '+OSName);
