如何使用MVC4在Controller中获得主机

Question

我想获得一个主机名，以在主机上应用特定角色，因为我为同一应用程序文件夹托管了两个网站。

我需要在Controller中获得一个HOST才能定义此角色。

像这样：

public override void Initialize(System.Web.Routing.RequestContext requestContext)
{
    base.Initialize(requestContext);

    if (host == "mycustomhost.com")
    {
        ViewBag.Theme = "CustomTheme";
    }
    else
    {
        ViewBag.Theme = "DefaultTheme";
    }
}

Answer 1

你尝试过这样的事情吗？

public override void Initialize(System.Web.Routing.RequestContext requestContext)
{
    base.Initialize(requestContext);

    var customHost = ConfigurationManager.AppSettings["CustomHost"];
    string theme = String.Empty;

    if (customHost.ToLower().Contains(requestContext.HttpContext.Request.Url.Host.ToLower()))
    {
        ViewBag.Theme = "CustomTheme";
    }
    else
    {
        ViewBag.Theme = "DefaultTheme";
    }
}

protected override void Initialize(System.Web.Routing.RequestContext requestContext)
{
    var hostname = requestContext.HttpContext.Request.Url.Host;

    // do something based on 'hostname' value
    // ....

    base.Initialize(requestContext);
}
