如何在NGINX中获取URL的子域 [英] How to get subdomain of URL in NGINX

问题描述

我想根据用户输入的子域进行重定向.

I am wanting to do a redirect based on what subdomain the user is entering.

例如:

<subdomain>.example.com/admin -> <subdomain>.myurl.com

理想情况下，我想将<subdomain>作为参数传递给我的重定向URL.

Ideally I want to pass <subdomain> as a parameter to my redirect URL.

我正在寻找与此类似的东西:

I was looking at something along the lines of this:

location ~ (sub).(somewhere).(com)/(some)(thing)/(something)(else) {
  set $var1 = $1; # = sub in above example
  set $var2 = $2; # = somewhere in above example
  set $var3 = $3; # = com in above example
  set $var4 = $4; # = some in above example
  set $var5 = $5; # = thing in above example
  set $var6 = $6; # = something in above example
  set $var7 = $7; # = else in above example
  rewrite ^ $1/$2 last; # would be sub/somewhere
}

根据此处的这篇文章:操纵或分割字符串(我认为变量集在此示例中是错误的，但您可以理解要点).

based on this post here: Manipulate or split string (I think the syntax of the variable set is wrong in this example but you get the gist).

推荐答案

URL的域名部分未通过location指令进行测试.您将需要在server_name指令中使用命名捕获.有关详细信息，请参见本文档.

The domain name part of the URL is not tested by the location directive. You will need to use a named capture in the server_name directive. See this document for details.

例如:

server {
    server_name ~^(?<name>\w+)\.example\.com$;

    location /admin {
        return 301 $scheme://$name.myurl.com/;
    }
}
