从浏览器检测确切的操作系统版本
我想知道是否有一种方法可以使用 PHP/JS/ASP 从我的浏览器中检测到确切的操作系统版本?
I was wondering if there is a way I can detect the exact Operating System version from my browser using PHP/JS/ASP?
我知道我可以检测操作系统的类型(Windows XP、Windows Vista、OS X 等)，但我需要检测确切的版本:Vista Business、Vista Ultimate、Windows XP Home、Windows XP Pro 等..
I know I can detect the type of OS (Windows XP,Windows Vista,OS X,etc) but I need to detect the exact version: Vista Business, Vista Ultimate, Windows XP Home, Windows XP Pro, etc...
推荐答案
简短回答:你不能.
长答案:
您所拥有的只是 HTTP User-Agent 标头中的信息，其中通常包含操作系统名称和版本.
All you have is the information in the HTTP User-Agent header, which usually contains the OS name and version.
通常，在 Mac OS 和 Linux 上运行的浏览器会发送足够的信息来识别确切的操作系统.例如，这是我的 User-Agent 标头:
Usually, browsers running on Mac OS and Linux send enough information to identify the exact OS. For example, here's my User-Agent header:
Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.7) Gecko/2009030423 Ubuntu/8.10 (intrepid) Firefox/3.0.7
Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.7) Gecko/2009030423 Ubuntu/8.10 (intrepid) Firefox/3.0.7
你可以看到我正在运行 Ubuntu 8.10 Intrepid Ibex.
You can see that I'm running Ubuntu 8.10 Intrepid Ibex.
以下是 Firefox 和 Safari 4 Beta 在我的 MacBook Pro 上的报告:
And here's what Firefox and Safari 4 Beta report on my MacBook Pro:
Mozilla/5.0(Macintosh；U；Intel Mac OS X 10.5；en-US；rv:1.9.0.7)Gecko/2009021906 Firefox/3.0.7
Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.0.7) Gecko/2009021906 Firefox/3.0.7
Mozilla/5.0(Macintosh；U；Intel Mac OS X 10_5_6；en-us)AppleWebKit/528.16(KHTML，如 Gecko)版本/4.0 Safari/528.16
Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_5_6; en-us) AppleWebKit/528.16 (KHTML, like Gecko) Version/4.0 Safari/528.16
另一方面，Windows 浏览器通常只报告操作系统版本而不是特定的软件包(Pro、Business 等):
Windows browsers, on the other hand, usually only report the OS version and not the specific package (Pro, Business, etc.):
Mozilla/5.0(Windows；U；Windows NT 5.1；en-US；rv:x.x.x)Gecko/20041107 Firefox/x.x
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:x.x.x) Gecko/20041107 Firefox/x.x
