MVC5根据域名切换View模板_ASP.NET获取当前访问域名

最近有这么一个需求、就是通过不同的域名访问跳转不同的View、其实实现起来并不难、不过一般在项目上线的时候经常会有类似的需求、下面就跟大家分享一下解决方案

重写模板查找方式

public class MyRazorViewEngine : RazorViewEngine
{
    public MyRazorViewEngine() : base()
    {

    }
    private const  string DefaultView = "~/Views/";
    private const string MoblieDomain = "m.";
    private const string WwwFolder = "~/Views/www/";
    private const string MoblieFolder = "~/Views/mobile/";

    public static string GetView(HttpRequestBase request)
    {
        if (request.Url == null) return DefaultView;
        var url = request.Url.Host;
        return url.Contains(MoblieDomain) ? MoblieFolder : WwwFolder;
    }
    string GetView(ControllerContext controllerContext)
    {
        return GetView(controllerContext.HttpContext.Request);
    }
    protected override IView CreatePartialView(ControllerContext controllerContext, string partialPath)
    {
        var views = GetView(controllerContext);
        return base.CreatePartialView(controllerContext, partialPath.Replace(DefaultView,views));
    }
    protected override IView CreateView(ControllerContext controllerContext, string viewPath, string masterPath)
    {
        var views = GetView(controllerContext);
        return base.CreateView(controllerContext, viewPath.Replace(DefaultView, views),
            masterPath.Replace(DefaultView, views));
    }
    protected override bool FileExists(ControllerContext controllerContext, string virtualPath)
    {
        var views = GetView(controllerContext);
        return base.FileExists(controllerContext, virtualPath.Replace(DefaultView, views));
    }
}

Application_Start()注册

ViewEngines.Engines.Add(new MyRazorViewEngine());
_ViewStart.cshtml
@{ 
    Layout = "~/Views/Shared/_Layout.cshtml".Replace("~/Views/", MyRazorViewEngine.GetView(Request)); 
}
