问题 Is there a way to detect the platform (Window / Linux) in which the website is running by Groovy / Grails? 回答1: System.properties['os.name'] will return the name of the OS, e.g. "Windows XP". So if you want to figure out whether you're running on Windows or not, you could do something like: if (System.properties['os.name'].toLowerCase().contains('windows')) { println "it's Windows" } else { println "it's not Windows" } Alternatively, org.apache.commons.lang.SystemUtils (from the Apache

问题 I'm working on a couple of Linux tools and need to prevent installation on Windows, since it depends on FHS and is thus rendered useless on that platform. The platform.platform function comes close but only returns a string. Unfortunately I don't know what to search for in that string for it to yield a reliable result. Does anyone know what to search for or does anyone know of another function that I'm missing here? 回答1: >>> import platform >>> platform.system() 'Windows' 回答2: For those that

问题 In a .NET 2.0 C# application I use the following code to detect the operating system platform: string os_platform = System.Environment.OSVersion.Platform.ToString(); This returns \"Win32NT\". The problem is that it returns \"Win32NT\" even when running on Windows Vista 64-bit. Is there any other method to know the correct platform (32 or 64 bit)? Note that it should also detect 64 bit when run as a 32 bit application on Windows 64 bit. 回答1: IntPtr.Size won't return the correct value if

Detecting a mobile browser

问题 I\'m looking for a function which return boolean value if user has mobile browser or not. I know that I can use navigator.userAgent and write that function by using regex, but user-agents are too various for different platforms. I doubt that match all possible devices would be easy, and I think this problem has been solved before many times so there should be some kind of complete solution for such task. I was looking at this site, but sadly the script is so cryptic that I have no idea how to
