将子域重定向到MVC Core中的区域

Question

It's takes many time from my day,

I have windows server 2016 as my server other side I develop my site in MVC core 2.2

OK

Try redirect form admin.mysite.com to mysite.com/admin when user write admin.mysite.com as url Redirect to mysite.com/admin

Test many ways:

1. use re-write in IIS whis this pattern: Area and subdomain routing

     <rules> <rule name="Rewrite sub-domain to dir"> <match url="^admin.*$" /> <conditions> <add input="{HTTP_HOST}" pattern="^admin\\.mysite\\.com$" /> </conditions> <action type="Rewrite" url="mysite.com/admin/{R:0}" /> </rule> </rules> </rewrite> 

2. use this way https://www.azurecurve.co.uk/2011/12/how-to-rewrite-a-sub-domain-to-a-directory-in-iis/ enter link description here

public class AreaRouter : MvcRouteHandler, IRouter
     {
   public new async Task RouteAsync(RouteContext context)
   {
       string url = context.HttpContext.Request.Headers["HOST"]; 
       var splittedUrl = url.Split('.');

       if (splittedUrl.Length > 0 && splittedUrl[0] == "admin")
       {
           context.RouteData.Values.Add("area", "Admin");
       }

       await base.RouteAsync(context);
    }
   }

but OP ways not work

Answer 1

As far as I know, if you want to redirect all the request from admin.mysite.com to mysite.com/admin by using url rewrite.

I suggest you could try below url rewrite rule:

Notice: The match url part will not match the host url like admin.mysite.com . It will just match the pattern part of the url like /admin/test .

       <rule name="Rewrite sub-domain to dir">
           <match url=".*" />
           <conditions>
               <add input="{HTTP_HOST}" pattern="^admin\.mysite\.com$" />
           </conditions>
           <action type="Rewrite" url="http://example.com/admin/{R:0}" />
       </rule>
