在 Nginx 中，如何重定向到另一个域，同时保留路径和子域？

在 Nginx 中，如何重定向到另一个域，同时保留路径和子域？

例如，我有一个域名olddomain.com，newdomain.com

以下是我希望请求重定向的工作方式：

sub.olddomain.com/hello/world -> sub.newdomain.com/hello/world olddomain.com/hello/world -> newdomain.com/hello/world

有许多子域，因此理想情况下我不想为每个子域都创建一条规则。

这似乎是一个解决方案：

server {
  listen 80;
  server_name olddomain.com *.olddomain.com;
  rewrite ^(/)(.*)$ http://newdomain.com/$2 permanent;
}

但它不适用于子域名，因为所有子域名都会重定向到newdomain.com/path而不考虑子域名。

你似乎正在寻找这样的东西：

if ($http_host ~ (.*)\.olddomain\.com) {
    set $subdomain $1;
    rewrite (.*)$ http://$subdomain.newdomain.com$1 permanent;
}
rewrite ^(/)(.*)$ http://newdomain.com/$2 permanent;

这些是我的测试用例
