我如何检测请求是否来自移动浏览器在我的asp.net MVC 3
本文关键字：浏览器 移动 我的 asp MVC net 何检测 检测 是否 请求 | 更新日期: 2023-09-27 18:05:13
我想要实现的很简单;在我的web应用程序中的所有视图中，我只有两个剃刀视图，我为它们创建了一个移动版本。所以我需要将用户重定向到这些视图，如果他们从他们的移动设备访问应用程序。我在控制器级别尝试了以下操作，但当我在不同的移动设备上运行测试时，它没有重定向用户:-
if (Request.Browser.IsMobileDevice)
{
return View("MobileStudentStartAssessment");
}
else {
return View("StudentStartAssessment");
}
那么，是否有另一种方法，我可以遵循，可以检测大多数移动设备?由于
您可以使用Request.Browser.IsMobileDevice属性。
假设您的移动视图用于所有移动设备(而不是具有特定于设备的视图)，您可以检查用户代理字符串，以查看应该返回哪个视图。这只是一个示例，但应该能让您了解更多:
private static string[] mobileDevices = new string[] {"iphone","ppc",
"windows ce","blackberry",
"opera mini","mobile","palm",
"portable","opera mobi" };
public static bool IsMobileDevice(string userAgent)
{
// TODO: null check
userAgent = userAgent.ToLower();
return mobileDevices.Any(x => userAgent.Contains(x));
}
if (MobileHelper.IsMobileDevice(Request.UserAgent))
{
// Return mobile view
}
如果您仍然发现它不能识别您的移动浏览器，请在调试器中检查用户代理字符串，看看是否有可以使用的标识符。
我用51度。Mobi包从nuget。这在检测所有不同的移动设备时更加准确。它立即起作用了。
当浏览器是移动设备时，我将其重定向到不同的区域。

使用WURFL http://wurfl.sourceforge.net/dotnet_index.php
如果你使用asp.net mvc，你可以使用ActionFilter
public class MobileActionFilterAttribute : ActionFilterAttribute
{
// The WURFL database contains information about a huge number of devices and mobile browsers.
// http://wurfl.sourceforge.net/
// http://wurfl.sourceforge.net/dotnet_index.php
// http://wurfl.sourceforge.net/help_doc.php
private static readonly IWURFLManager WurflManager;
static MobileActionFilterAttribute ()
{
IWURFLConfigurer configurer = new ApplicationConfigurer();
WurflManager = WURFLManagerBuilder.Build(configurer);
}
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
HttpRequestBase request = filterContext.RequestContext.HttpContext.Request;
// We don't have ARR server for dev environment, so we still need to check to see if the current domain name is the mobile site.
if (request.Url.AbsoluteUri.StartsWith(SiteConfiguration.Current.MobileSiteAddress, StringComparison.OrdinalIgnoreCase))
{
return;
}
// Creates a WURFLRequest object from an ASP.NET HttpRequest object
WURFLRequest wurflRequest = WURFLRequestFactory.CreateRequest(HttpContext.Current.Request);
// Indicates whether the current user agent string refers to a desktop agent.
if (wurflRequest.IsDesktopRequest)
return;
// Get the information about the device
IDevice deviceInfo = WurflManager.GetDeviceForRequest(wurflRequest);
// Tells you if a device is a tablet computer (iPad and similar, regardless of OS)
bool isTablet = string.Equals(deviceInfo.GetCapability("is_tablet") ?? string.Empty, "true", StringComparison.OrdinalIgnoreCase);
if (isTablet)
{
// so we don't show the mobile site for iPad.
return;
}
// Indicates whether the current user agent string refers to a mobile device.
bool isMobileRequest = wurflRequest.IsMobileRequest;
// Tells you if a device is wireless or not. Specifically a mobile phone or a PDA are considered wireless devices, a desktop PC or a laptop are not
bool isWirelessDevice = string.Equals(deviceInfo.GetCapability("is_wireless_device") ?? string.Empty, "true", StringComparison.InvariantCultureIgnoreCase);
if (isMobileRequest && isWirelessDevice)
{
// we can redirect to the mobile site!
filterContext.Result = new RedirectResult(SiteConfiguration.Current.MobileSiteAddress);
}
}
}
我使用这个方法来检测手机和桌面
if (eDurar.MobileDetect.DeviceType.Any(m => Request.UserAgent.Contains(m)))
{
Layout = "~/Views/Shared/_mobileLayout.cshtml";
@Html.Partial("mobileIndex");
}
else
{
Layout = "~/Views/Shared/_Layout.cshtml";
@Html.Partial("desktopIndex");
}
可以使用
if (Request.Browser["IsMobileDevice"] == "true")
{
//Mobile Browser Detected
}
else
{
//Desktop Browser Detected
}
使用51Degrees的开源。net Api，您可以在这里获得，https://github.com/51Degrees/dotNET-Device-Detection，您可以检测各种各样的移动设备。
你可以在51度做类似的事情。配置文件以启用重定向。
<redirect devicesFile="" timeout="20" firstRequestOnly="true"
originalUrlAsQueryString="false" mobileHomePageUrl="~/Mobile/StudentStartAssessment.aspx"
mobilePagesRegex="/Mobile/">

检查请求是否来自移动设备，您可以使用
HttpContext.Request.Browser.IsMobileDevice
，因为这将返回一个布尔值结果。
