Asp.net mvc ASP.NET MVC子域

Asp.net mvc ASP.NET MVC子域,asp.net-mvc,subdomain,Asp.net Mvc,Subdomain,我有这样的主机和域名: www.EXAMPLE.com www.PAGE1.EXAMPLE.com www.PAGE2.EXAMPLE.com www.PAGE3.EXAMPLE.com ... etc... 我已经创建了几个这样的子域: www.EXAMPLE.com www.PAGE1.EXAMPLE.com www.PAGE2.EXAMPLE.com www.PAGE3.EXAMPLE.com ... etc... 所有这些子域都指向同一个ASP.NET MVC 5应用程序 我想做

我有这样的主机和域名:

www.EXAMPLE.com
www.PAGE1.EXAMPLE.com
www.PAGE2.EXAMPLE.com
www.PAGE3.EXAMPLE.com
... etc...
我已经创建了几个这样的子域:

www.EXAMPLE.com
www.PAGE1.EXAMPLE.com
www.PAGE2.EXAMPLE.com
www.PAGE3.EXAMPLE.com
... etc...
所有这些子域都指向同一个ASP.NET MVC 5应用程序

我想做一个系统,它将根据子域加载数据。 例如:

我有文章对象,可以是自动评论、游戏评论或书评等

我想在www.auto.example.com加载文章类型为auto的数据,在www.book.example.com加载书籍类型的数据等

将有许多类型的页面

这样做的最佳实践是什么


顶级域www.example.com应显示其他内容。这将是其他人的主页。

您可以通过编写自定义路由来实现这一点。以下是如何(改编自)

以及您的控制器方法:

public ActionResult Index(string subdomain)
{
    //Query your database for the relevant articles based on subdomain
    var viewmodel = MyRepository.GetArticles(subdomain);
    Return View(viewmodel);
}

这是我很久以来一直想用ASP.NET MVC做的事情,但是。。。这不是ASP.NET MVC负责的问题。这是一个服务器问题(IIS)。您需要做的是允许在IIS服务器上使用通配符子域,并将它们指向您的one应用程序

然后您可以使用HttpContext执行类似的操作:

HttpContext.Current.Request.Url.Host // user1.yourwebsite.com
然后,您只需解析它,并将其推送到您的ASP.NET MVC应用程序中,不管您认为合适:

  • 把它推到会话中
  • 更新当前路线数据并输入值
  • 等等
选择真的取决于你


注意:这里的缺点是,这使得本地开发变得越来越困难,因此您可能希望模拟一种方法,在应用程序中伪造子域。

我尝试了
Paul Taylor
上面的答案很好,但这对我来说并不完全有效。 我使用
Route
类的这个实现

将自定义域添加到
C:/Windows/System32/drivers/etc/hosts
文件中
