我该如何检测用户操作系统

Question

我有以下代码来获取用户详细信息:

HttpBrowserCapabilities bc = HttpContext.Current.Request.Browser;
string UserAgent = HttpContext.Current.Request.UserAgent;

ENT_TrackingData ret = new ENT_TrackingData()
{
    IPAddress = HttpContext.Current.Request.UserHostAddress,
    Browser = bc.Browser + " " + bc.Version,                
    DateStamp = DateTime.Now,
    PageViewed = HttpContext.Current.Request.Url.AbsolutePath,
    NodeId = UmbracoHelper.GetCurrentNodeID(),
    IsMobileDevice = IsMobileDevice(UserAgent),
    Platform = bc.Platform
};

这很好但我注意到平台总是说我的机器的Windows NT不是Windows 7.有没有办法在ASP.Net中检测这种类型的信息？

Answer 1

这是我想出来的,它似乎运作得相当好:

public String GetUserEnvironment(HttpRequest request)
{
    var browser = request.Browser;
    var platform = GetUserPlatform(request);
    return string.Format("{0} {1} / {2}", browser.Browser, browser.Version, platform);
}

public String GetUserPlatform(HttpRequest request)
{
    var ua = request.UserAgent;

    if (ua.Contains("Android"))
        return string.Format("Android {0}", GetMobileVersion(ua, "Android"));

    if (ua.Contains("iPad"))
        return string.Format("iPad OS {0}", GetMobileVersion(ua, "OS"));

    if (ua.Contains("iPhone"))
        return string.Format("iPhone OS {0}", GetMobileVersion(ua, "OS"));

    if (ua.Contains("Linux") && ua.Contains("KFAPWI"))
        return "Kindle Fire";

    if (ua.Contains("RIM Tablet") || (ua.Contains("BB") && ua.Contains("Mobile")))
        return "Black Berry";

    if (ua.Contains("Windows Phone"))
        return string.Format("Windows Phone {0}", GetMobileVersion(ua, "Windows Phone"));

    if (ua.Contains("Mac OS"))
        return "Mac OS";

    if (ua.Contains("Windows NT 5.1") || ua.Contains("Windows NT 5.2"))
        return "Windows XP";

    if (ua.Contains("Windows NT 6.0"))
        return "Windows Vista";

    if (ua.Contains("Windows NT 6.1"))
        return "Windows 7";

    if (ua.Contains("Windows NT 6.2"))
        return "Windows 8";

    if (ua.Contains("Windows NT 6.3"))
        return "Windows 8.1";

    if (ua.Contains("Windows NT 10"))
        return "Windows 10";

    //fallback to basic platform:
    return request.Browser.Platform + (ua.Contains("Mobile") ? " Mobile " : "");
}

public String GetMobileVersion(string userAgent, string device)
{
    var temp = userAgent.Substring(userAgent.IndexOf(device) + device.Length).TrimStart();
    var version = string.Empty;

    foreach (var character in temp)
    {
        var validCharacter = false;
        int test = 0;

        if (Int32.TryParse(character.ToString(), out test))
        {
            version += character;
            validCharacter = true;
        }

        if (character == '.' || character == '_')
        {
            version += '.';
            validCharacter = true;
        }

        if (validCharacter == false)
            break;
    }

    return version;
}

Answer 2

使用Request.UserAgent

if (Request.UserAgent.IndexOf("Windows NT 5.1") > 0)
{
//xp
}
else if (Request.UserAgent.IndexOf("Windows NT 6.0") > 0)
{
//VISTA
}
else if (Request.UserAgent.IndexOf("Windows NT 6.1") > 0)
{
//7
}
else if (Request.UserAgent.IndexOf("Windows NT 6.2") > 0) 
{ 
//8
}
else if (Request.UserAgent.IndexOf("Windows NT 6.3") > 0) 
{ 
//8.1
}
else if (Request.UserAgent.IndexOf("Windows NT 10.0") > 0) 
{ 
//10
}

Answer 3

根据This Official Microsoft Document,我们可以使用它来检测Windows操作系统:

String userAgent = Request.UserAgent;

if (userAgent.IndexOf("Windows NT 6.3") > 0)
{
    //Windows 8.1
}
else if (userAgent.IndexOf("Windows NT 6.2") > 0)
{
    //Windows 8
}
else if (userAgent.IndexOf("Windows NT 6.1") > 0)
{
    //Windows 7
}
else if (userAgent.IndexOf("Windows NT 6.0") > 0) 
{ 
    //Windows Vista
}
else if (userAgent.IndexOf("Windows NT 5.2") > 0) 
{ 
    //Windows Server 2003; Windows XP x64 Edition
}
else if (userAgent.IndexOf("Windows NT 5.1") > 0) 
{ 
    //Windows XP
}
else if (userAgent.IndexOf("Windows NT 5.01") > 0) 
{ 
    //Windows 2000, Service Pack 1 (SP1)
}
else if (userAgent.IndexOf("Windows NT 5.0") > 0) 
{ 
    //Windows 2000
}
else if (userAgent.IndexOf("Windows NT 4.0") > 0) 
{ 
    //Microsoft Windows NT 4.0
}
else if (userAgent.IndexOf("Win 9x 4.90") > 0) 
{ 
    //Windows Millennium Edition (Windows Me)
}
else if (userAgent.IndexOf("Windows 98") > 0) 
{ 
    //Windows 98
}
else if (userAgent.IndexOf("Windows 95") > 0) 
{ 
    //Windows 95
}
else if (userAgent.IndexOf("Windows CE") > 0) 
{ 
    //Windows CE
}
else
{ 
    //Others
}

Answer 4

有一个很酷的工具名为:https://github.com/ua-parser/uap-csharp
,它将用户代理解析为操作系统,浏览器,浏览器版本等...
链接到Nuget

这是如何使用它:

 public static string GetUserOS(string userAgent)
 {
    // get a parser with the embedded regex patterns
    var uaParser = Parser.GetDefault();
    ClientInfo c = uaParser.Parse(userAgent);
    return c.OS.Family;
 }

                this.os_version = version;
            }
        }

用法

var os = new OS();
os.os_name; // here is os name
os.os_version; // here is os vers

没有准确的方法可以做到这一点，因为您从用户请求的标头中获得的所有信息都可以很容易地被用户更改并且可以包含任何内容。

如果您同意阅读可能不准确的信息，那么您可能需要检查类似问题的答案
