如何在NGINX中获取URL的子域名

我想根据用户输入的子域进行重定向.

例如：

< subdomain> .example.com / admin – > &LT亚结构域&GT .myurl.com

理想情况下,我想传递< subdomain>作为我的重定向网址的参数.

我正在寻找与此类似的东西：

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
}

基于这篇文章在这里：Manipulate or split string(我认为变量集的语法在这个例子中是错误的,但你得到了要点).

解决方法:

URL的域名部分未经location指令测试.您需要在server_name指令中使用命名捕获.有关详情,请参见this document.

例如：

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

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