如何使用MVC4在Controller中獲得主機

Question

我想獲得一個主機名，以在主機上應用特定角色，因為我為同一應用程序文件夾托管了兩個網站。

我需要在Controller中獲得一個HOST才能定義此角色。

像這樣：

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

你嘗試過這樣的事情嗎？

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);
}
