在 ASP.NET MVC4 应用程序中

HttpContext.Current.Request.Browser.IsMobileDevice

用于检测移动设备。它为 MC2180 返回 false。

应用程序包含带有 .Mobile 的视图,作为移动设备视图名称的一部分。这些视图未呈现,常规浏览器视图出现。

应用程序是浏览器应用程序,它在移动和非移动设备上的浏览器中呈现不同的视图。

还安装了来自http://51degrees.codeplex.com/免费版的51 度 mobi 模块 。

如果使用摩托罗拉 MC2180 移动数据终端/手持扫描仪登录应用程序,则未检测为移动设备: .移动视图未执行,出现常规视图。

如何强制它被识别为移动设备?设备正在运行 Windows CE 6.0,它包含 Motorola Rhoelements RHOS 自定义浏览器,它返回版本字符串为

Mozilla/5.0 (Windows CE 6.0) AppleWebKit/534.51 (KHTML, like Gecko) MotorolaWebKit/2.1.8.7 Safari/534.51

应用程序应该在 Mono 和 ASP.NET 4 中。jQuery 和 jQuery-mobile 用于移动视图。

根据您提供的用户代理,我设法使用www.detectmobilebrowsers.com将该设备识别为移动设备。它使用正则表达式来评估用户代理,并以各种语言发布了许多示例。

我已将该示例改编为您可以调用的方法;

public bool DeviceIsMobile(string userAgent)
{
  Regex regex1 = new Regex(@"(android|bb\d+|meego).+mobile|avantgo|bada\/|blackberry|blazer|compal|elaine|fennec|hiptop|iemobile|ip(hone|od)|iris|kindle|lge |maemo|midp|mmp|mobile.+firefox|netfront|opera m(ob|in)i|palm( os)?|phone|p(ixi|re)\/|plucker|pocket|psp|series(4|6)0|symbian|treo|up\.(browser|link)|vodafone|wap|windows (ce|phone)|xda|xiino", RegexOptions.IgnoreCase | RegexOptions.Multiline);

  if ((regex1.IsMatch(userAgent) || regex2.IsMatch(userAgent.Substring(0, 4))))
  {
    return true;
  }

  return false;
}

你可以得到用户代理;

HttpContext.Current.Request.UserAgent

MVC3

您可以编写一个自定义ViewEngine来执行此检查并自动显示 .Mobile.cshtml 视图。Scott Hanselman 写了一篇关于如何编写可感知移动设备的 ViewEngine的好帖子——调整它应该可以满足您的需求;

public class MobileRazorViewEngine : RazorViewEngine
{
  public override ViewEngineResult FindView(ControllerContext controllerContext, 
    string viewName, string masterName, bool useCache)
    {
      string userAgent = controllerContext.HttpContext.Request.UserAgent;
      string overrideViewName = DeviceIsMobile(userAgent) ? viewName + ".Mobile" : viewName;

      ViewEngineResult result = NewFindView(controllerContext, overrideViewName, masterName, useCache);

      // If we're looking for a Mobile view and couldn't find it try again without modifying the viewname
      if (overrideViewName.Contains(".Mobile") && (result == null || result.View == null))
      {
        result = NewFindView(controllerContext, viewName, masterName, useCache);
      }

      return result;
    }

    private ViewEngineResult NewFindView(ControllerContext controllerContext, string viewName, string masterName, bool useCache)
    {
      // Get the name of the controller from the path
      string controller = controllerContext.RouteData.Values["controller"].ToString();
      string area = "";

      try
      {
        area = controllerContext.RouteData.DataTokens["area"].ToString();
      }
      catch
      {

      }

      // Create the key for caching purposes           
      string keyPath = Path.Combine(area, controller, viewName);

      // Try the cache           
      if (useCache)
      {
        //If using the cache, check to see if the location is cached.               
        string cacheLocation = ViewLocationCache.GetViewLocation(controllerContext.HttpContext, keyPath);

        if (!string.IsNullOrWhiteSpace(cacheLocation))
        {
          return new ViewEngineResult(CreateView(controllerContext, cacheLocation, masterName), this);
        }
      }

      // Remember the attempted paths, if not found display the attempted paths in the error message.           
      var attempts = new List<string>();

      string[] locationFormats = string.IsNullOrEmpty(area) ? ViewLocationFormats : AreaViewLocationFormats;

      // for each of the paths defined, format the string and see if that path exists. When found, cache it.           
      foreach (string rootPath in locationFormats)
      {
        string currentPath = string.IsNullOrEmpty(area) ? string.Format(rootPath, viewName, controller) : string.Format(rootPath, viewName, controller, area);

      if (FileExists(controllerContext, currentPath))
      {
        ViewLocationCache.InsertViewLocation(controllerContext.HttpContext, keyPath, currentPath);

        return new ViewEngineResult(CreateView(controllerContext, currentPath, masterName), this);
      }

      // If not found, add to the list of attempts.               
      attempts.Add(currentPath);
    }

    // if not found by now, simply return the attempted paths.           
    return new ViewEngineResult(attempts.Distinct().ToList());
  }
}

要使用它,您需要将 ViewEngine 添加到您的App_Start并使用;

ViewEngines.Engines.Add(new MobileRazorViewEngine());

MVC4

正如 Andrus 所指出的,上述使用 ViewEngines 的答案是针对 MVC3 的。在 MVC4 中,您可以扩展DefaultDisplayMode为编写自己的移动自定义检查;

public class RegexMobileDisplay : DefaultDisplayMode
{
  public RegexMobileDisplay() : base("Mobile")
  {
    ContextCondition = context => DeviceIsMobile(context.Request.UserAgent);
  }
}

并在 App_Start 中注册;

DisplayModeProvider.Instance.Modes.Insert(0, new RegexMobileDisplay());

我希望这有帮助。
