如何使用MVC4在Controller中获得主机

Question

I would like to get a HOST name to apply an specific role for on host, because I have 2 websites hosted for the same application folder.

I need get a HOST in my Controller to define this role.

Some like this:

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

Have you tried something like this?

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);
}
